Introduction
************
This manual corresponds to version 3.2 of the Kpathsea library,
released in October 1997.
The library's fundamental purpose is to return a filename from a list
of directories specified by the user, similar to what shells do when
looking up program names to execute.
The following software, all of which we maintain, uses this library:
* Dviljk (see the `dvilj' man page)
* Dvipsk (*note Introduction: (dvips)Top.)
* GNU font utilities (*note Introduction: (fontu)Top.)
* Web2c (*note Introduction: (web2c)Top.)
* Xdvik (see the `xdvi' man page)
Other software that we do not maintain also uses it.
We are still actively maintaining the library (and probably always
will be, despite our hopes). If you have comments or suggestions,
please send them to us (*note Reporting bugs::.).
We distribute the library under the GNU Library General Public License
(LGPL), with one exception (see below). In short, this means if you
write a program using the library, you must (offer to) distribute the
source to the library, along with any changes you have made, and allow
anyone to modify the library source and distribute their modifications.
It does not mean you have to distribute the source to your program,
although we hope you will.
The exception is the part of the file `expand.c' which implements
brace expansion. We took this from Bash, which is covered by the GNU
General Public License (GPL). Therefore, if you wish to redistribute
the library under the LGPL, you must remove this code. (If you write a
replacement we can distribute, we hope you'll share it with us.) See
the files `COPYING' and `COPYING.LIB' for the text of the GNU licenses.
If you know enough about TeX to be reading this manual, then you (or
your institution) should consider joining the TeX Users Group (if
you're already a member, great!). TUG produces the periodical
`TUGboat', sponsors an annual meeting and publishes the proceedings,
and arranges courses on TeX for all levels of users throughout the
world. Anyway, here is the address:

History
=======
(This section is for those people who are curious about how the
library came about.) (If you like to read historical accounts of
software, we urge you to seek out the GNU Autoconf manual and the
"Errors of TeX" paper by Don Knuth, published in `Software--Practice and
Experience' 19(7), July 1989.)
[Karl writes.] My first ChangeLog entry for Web2c seems to be
February 1990, but I may have done some work before then. In any case,
Tim Morgan and I were jointly maintaining it for a time. (I should
mention here that Tim had made Web2c into a real distribution long
before I had ever used it or even heard of it, and Tom Rokicki did the
original implementation. I was using `pxp' and `pc' on VAX 11/750's
and the hot new Sun 2 machines.)
It must have been later in 1990 and 1991 that I started working on
`TeX for the Impatient'. Dvips, Xdvi, Web2c, and the GNU fontutils
(which I was also writing at the time) all used different environment
variables, and, more importantly, had different bugs in their path
searching. This became extremely painful, as I was stressing everything
to the limit working on the book. I also desperately wanted to
implement subdirectory searching, since I couldn't stand putting
everything in one big directory, and also couldn't stand having to
explicitly specify `cm', `pandora', ... in a path.
In the first incarnation, I just hacked separately on each
program--that was the original subdirectory searching code in both Xdvi
and Dvips, though I think Paul Vojta has completely rewritten Xdvi's
support by now. That is, I tried to go with the flow in each program,
rather than changing the program's calling sequences to conform to
common routines.
Then, as bugs inevitably appeared, I found I was fixing the same thing
three times (Web2c and fontutils were always sharing code, since I
maintained those--there was no Dvipsk or Xdvik or Dviljk at this
point). After a while, I finally started sharing source files. They
weren't yet a library, though. I just kept things up to date with shell
scripts. (I was developing on a 386 running ISC 2.2 at the time, and so
didn't have symbolic links. An awful experience.)
The ChangeLogs for Xdvik and Dvipsk record initial releases of those
distributions in May and June 1992. I think it was because I was tired
of the different configuration strategies of each program, not so much
because of the path searching. (Autoconf was being developed by David
MacKenzie and others, and I was adapting it to TeX and friends.)
I started to make a separate library that other programs could link
with on my birthday in April 1993, according to the ChangeLog. I don't
remember exactly why I finally took the time to make it a separate
library; a conversation with david zuhn that initiated it. Just seemed
like it was time.
Dviljk got started in March 1994 after I bought a Laserjet 4.
(Kpathsea work got suspended while Norm Walsh and I, with Gustaf
Neumann's help, implemented a way for TeX to get at all those neat
builtin LJ4 fonts ... such a treat to have something to typeset in
besides Palatino!)
By spring of 1995, I had implemented just about all the path-searching
features in Kpathsea that I plan to, driven beyond my initial goals by
Thomas Esser and others. I then started to integrate Web2c with
Kpathsea. After the release of a stable Web2c, I hope to be able to stop
development, and turn most of my attention back to making fonts for GNU.
(Always assuming Micros**t hasn't completely obliterated Unix by then,
or that software patents haven't stopped software development by anybody
smaller than a company with a million-dollar-a-year legal budget. Which
is actually what I think is likely to happen, but that's another
story...)
[Olaf writes.] At the end of 1997, UNIX is still alive and kicking,
individuals still develop software, and Web2c development still
continues. Karl had been looking for some time for someone to take up
part of the burden, and I volunteered.

(A copy of this chapter is in the distribution file
`kpathsea/INSTALL'.)

installation follows. If you encounter trouble, see *Note Common

Simple installation
===================
Installing TeX and friends for the first time can be a daunting
experience. Thus, you may prefer to skip this whole thing and just get
precompiled executables: see *Note unixtex.ftp::.
This section explains what to do if you wish to take the defaults for
everything, and generally to install in the simplest possible way. Most
steps here refer to corresponding subsection in the next section which
explains how to override defaults and generally gives more details.
By default everything will be installed under `/usr/local' and the
following discussion assumes this. However, if you already have TeX
installed, its location is used to derive the directory under which
everything is to be installed.
1. Be sure you have enough disk space: approximately 8 megabytes for
the compressed archives, 15MB for sources, 45MB for compilation,
40MB for the (initial) installed system (including library files).
*Note Disk space::.
2. Retrieve these two distribution archives:
`ftp://ftp.tug.org/tex/texk.tar.gz'
These are the sources, which you will be compiling.
`ftp://ftp.tug.org/tex/texmflib.tar.gz'
This is a basic set of input files. You should unpack it in
the directory `/usr/local/share'; doing so will create a
`texmf' subdirectory there.
*Note Kpathsea application distributions::.
3. When using the default search paths, there is no need to edit any
distribution files. *Note Changing search paths::.
4. At the top level of the distribution, run `sh configure'. (If you
have the GNU Bash shell installed, run `bash configure'.) *Note
Running configure::.
5. `make'. *Note Running make::. If you are using a BSD 4.4 system
such as FreeBSD or NetBSD, use GNU make (often installed in
`/usr/local/bin'), not the BSD make.
If you are using a HP-UX 10 system and the native compiler,
specify the `+u' flag in `XCFLAGS'.
6. `make install'. *Note Installing files::.
7. `make distclean'. *Note Cleaning up::.
8. Set up a cron job to rebuild the filename database that makes
searching faster. This line will rebuild it every midnight:
0 0 * * * cd /usr/local/share/texmf && /BINDIR/mktexlsr
*Note Filename database generation::, and *Note Filename
database::.
9. If you're installing Dvips, you also need to set up configuration
files for your printers and make any additional PostScript fonts
available. *Note Installation: (dvips)Installation. If you have
any color printers, see *Note Color device configuration:
(dvips)Color device configuration.
10. The first time you run a DVI driver, a bunch of PK fonts will be
built by Metafont via `mktexpk' (and added to the filename
database). This will take some time. Don't be alarmed; they will
created only this first time (unless something is wrong with your
path definitions).
By default, `mktexpk' will create these fonts in a hierarchy under
`/var/tmp/texfonts'; it simply assumes that `/var/tmp' exists and
is globally writable. If you need a different arrangement, see
*Note mktex configuration::.
*Note mktex scripts::.
11. For some simple tests, try `tex story \\bye' and `latex sample2e'.
Then run `xdvi story' or `dvips sample2e' on the resulting DVI
files to preview/print the documents. *Note Installation
testing::.
File: kpathsea.info, Node: Custom installation, Next: Security, Prev: Simple installation, Up: Installation
Custom installation
===================
Most sites need to modify the default installation procedure in some
way, perhaps merely changing the prefix from `/usr/local', perhaps
adding extra compiler or loader options to work around `configure'
bugs. This section explains how to override default choices. For
additional distribution-specific information:
* `dviljk/INSTALL'.
* *Note Installation: (dvips)Installation.
* *Note Installation: (web2c)Installation.
* `xdvik/INSTALL'.
These instructions are for Unix systems. Other operating-system
specific distributions have their own instructions. The code base
itself supports Amiga, DOS, OS/2, and VMS.
Following are the same steps as in the previous section (which
describes the simplest installation), but with much more detail.

Kpathsea application distributions
----------------------------------
The archive `ftp://ftp.tug.org/tex/texk.tar.gz' contains all of the
Kpathsea applications I maintain, and the library itself. For example,
since NeXT does not generally support X11, you'd probably want to skip
`xdvik' (or simply remove it after unpacking `texk.tar.gz'. If you are
not interested in all of them, you can also retrieve them separately:
`dviljk.tar.gz'
DVI to PCL, for LaserJet printers.
`dvipsk.tar.gz'
DVI to PostScript, for previewers, printers, or PDF generation.
`web2c.tar.gz'
The software needed to compile TeX and friends.
`web.tar.gz'
The original WEB source files, also used in compilation.
`xdvik.tar.gz'
DVI previewing under the X window system.
If you want to use the Babel LaTeX package for support of non-English
typesetting, you may need to retrieve additional files. See the file
`install.txt' in the Babel distribution.
File: kpathsea.info, Node: Changing search paths, Next: Running configure, Prev: Kpathsea application distributions, Up: Custom installation
Changing search paths
---------------------
If the search paths for your installation differ from the standard
TeX directory structure (*note Introduction: (tds)Top.), edit the file
`kpathsea/texmf.in' as desired, before running `configure'. For
example, if you have all your fonts or macros in one big directory.
You may also wish to edit the file `mktex.cnf', either before or
after installation, to control various aspects of `mktexpk' and
friends. *Note mktex configuration::.
You do not need to edit `texmf.in' to change the default top-level or
other installation *directories* (only the paths). You can and should
do that when you run `configure' (next step).
You also do not need to edit `texmf.in' if you are willing to rely on
`texmf.cnf' at runtime to define the paths, and let the compile-time
default paths be incorrect. Usually there is no harm in doing this.
The section below explains default generation in more detail.
* Menu:
* Default path features::
* Default path generation::
File: kpathsea.info, Node: Default path features, Next: Default path generation, Up: Changing search paths
Default path features
.....................
The purpose of having all the different files described in the section
above is to avoid having the same information in more than one place. If
you change the installation directories or top-level prefix at
`configure'-time, those changes will propagate through the whole
sequence. And if you change the default paths in `texmf.in', those
changes are propagated to the compile-time defaults.
The Make definitions are all repeated in several Makefile's; but
changing the top-level `Makefile' should suffice, as it passes down all
the variable definitions, thus overriding the submakes. (The
definitions are repeated so you can run Make in the subdirectories, if
you should have occasion to.)
By default, the bitmap font paths end with `/$MAKETEX_MODE', thus
including the device name (usually a Metafont mode name such as
`ljfour'). This distinguishes two different devices with the same
resolution--a write/white from a write/black 300dpi printer, for
example.
However, since most sites don't have this complication, Kpathsea
(specifically, the `kpse_init_prog' function in `kpathsea/proginit.c')
has a special case: if the mode has not been explicitly set by the user
(or in a configuration file), it sets `MAKETEX_MODE' to `/'. This
makes the default PK path, for example, expand into `.../pk//', so
fonts will be found even if there is no subdirectory for the mode (if
you arranged things that way because your site has only one printer,
for example) or if the program is mode-independent (e.g., `pktype').
To make the paths independent of the mode, simply edit `texmf.in'
before installation, or the installed `texmf.cnf', and remove the
`$MAKETEX_MODE'.
*Note mktex script arguments::, for how this interacts with `mktexpk'.
*Note TeX directory structure: TeX directory structure, for a
description of the default arrangement of the input files that comprise
the TeX system. The file `kpathsea/HIER' is a copy of that section.
File: kpathsea.info, Node: Default path generation, Prev: Default path features, Up: Changing search paths
Default path generation
.......................
This section describes how the default paths are constructed.
You may wish to ignore the whole mess and simply edit `texmf.cnf'
after it is installed, perhaps even copying it into place beforehand so
you can complete the installation, if it seems necessary.
To summarize the chain of events that go into defining the default
paths:
1. `configure' creates a `Makefile' from each `Makefile.in'.
2. When Make runs in the `kpathsea' directory, it creates a file
`texmf.sed' that substitutes the Make value of `$(var)' for a
string `@var@'. The variables in question are the one that define
the installation directories.
3. `texmf.sed' (together with a little extra magic--see
`kpathsea/Makefile') is applied to `texmf.in' to generate
`texmf.cnf'. This is the file that will eventually be installed
and used.
4. The definitions in `texmf.cnf' are recast as C `#define''s in
`paths.h'. These values will be the compile-time defaults; they
are not used at runtime unless no `texmf.cnf' file can be found.
(That's a lie: the compile-time defaults are what any extra :'s in
`texmf.cnf' expand into; but the paths as distributed have no extra
:'s, and there's no particular reason for them to.)
File: kpathsea.info, Node: Running configure, Next: Running make, Prev: Changing search paths, Up: Custom installation
Running `configure'
-------------------
Run `sh configure OPTIONS' (in the top-level directory, the one
containing `kpathsea/'), possibly using a shell other than `sh' (*note
configure shells::.).
`configure' adapts the source distribution to the present system via
`#define''s in `*/c-auto.h', which are created from the corresponding
`c-auto.in'. It also creates a `Makefile' from the corresponding
`Makefile.in', doing `@VAR@' and `ac_include' substitutions).
`configure' is the best place to control the configuration,
compilation, and installed location of the software, either via
command-line options, or by setting environment variables before
invoking it. For example, you can disable `mktexpk' by default with
the option `--disable-mktexpk'. *Note configure options::.

`configure' shells
..................
If you have Bash, the GNU shell, use it if `sh' runs into trouble
(*note Top: (features)Top.).
Most Bourne shell variants other than Bash cannot handle `configure'
scripts as generated by GNU Autoconf (*note Introduction:
(autoconf)Top.). Specifically:
`ksh'
The Korn shell may be installed as `/bin/sh' on AIX. `/bin/bsh'
may serve instead.
`ash'
Ash is sometimes installed as `/bin/sh' on NetBSD, FreeBSD, and
Linux systems. `/bin/bash' should be available.
`Ultrix /bin/sh'
`/bin/sh' under Ultrix is a DEC-grown shell that is notably
deficient in many ways. `/bin/sh5' may be necessary.

...................
For a complete list of all `configure' options, run `configure
--help' or see *Note Running `configure' scripts: (autoconf)Invoking
configure, (a copy is in the file `kpathsea/README.CONFIGURE'). The
generic options are listed first in the `--help' output, and the
package-specific options come last. The environment variables
`configure' pays attention to are listed below.
Options particularly likely to be useful are `--prefix', `--datadir',
and the like; see *Note configure scenarios::.
This section gives pointers to descriptions of the `--with' and
`--enable' options to `configure' that Kpathsea-using programs accept.
`--without-mktexmf-default'
`--without-mktexpk-default'
`--without-mktextfm-default'
`--with-mktextex-default'
Enable or disable the dynamic generation programs. *Note mktex
configuration::.
`--enable-shared'
Build Kpathsea as a shared library, and link against it. Also
build the usual static library. *Note Shared library::.
`--disable-static'
Build only the shared library. Implies `--enable-shared'.
`--enable-maintainer-mode'
Enables make targets that are useful for the maintainer and likely
to be a pain for anyone else; the makefiles created when this
option is enabled may not work at all for you. You have been
warned.
File: kpathsea.info, Node: configure environment, Next: configure scenarios, Prev: configure options, Up: Running configure
`configure' environment
.......................
`configure' uses the value of the following environment variables in
determining your system's characteristics, and substitutes for them in
Makefile's:
`CC'
The compiler to use: default is `gcc' if it's installed, otherwise
`cc'.
`CFLAGS'
Options to give the compiler: default is `-g -O2' for `gcc', `-g'
otherwise. `CFLAGS' comes after any other options. You may need
to include `-w' here if your compilations commonly have useless
warnings (e.g., `NULL redefined'), or `configure' may fail to
detect the presence of header files (it takes the messages on
standard error to mean the header file doesn't exist).
`CPPFLAGS'
Options to pass to the compiler preprocessor; this matters most for
configuration, not the actual source compilation. The `configure'
script often does only preprocessing (e.g., to check for the
existence of #include files), and `CFLAGS' is not used for this.
You may need to set this to something like
`-I/usr/local/include/wwwhatever' if you have the libwww library
installed for hyper-xdvik (see `xdvik/INSTALL').
`DEFS'
Additional preprocessor options, but not used by `configure'.
Provided for enabling or disabling program features, as documented
in the various program-specific installation instructions. `DEFS'
comes before any compiler options included by the distribution
`Makefile's or by `configure'.
`LDFLAGS'
Additional options to give to the loader. `LDFLAGS' comes before
any other linker options.
`LIBS'
Additional libraries to link with.
File: kpathsea.info, Node: configure scenarios, Next: Shared library, Prev: configure environment, Up: Running configure
`configure' scenarios
.....................
Here are some common installation scenarios:
* Including X support in Metafont. This is disabled by default,
since many sites have no use for it, and it's a leading cause of
configuration problems.
configure --with-x-toolkit
* Putting the binaries, TeX files, GNU info files, etc. into a single
TeX hierarchy, say `/texmf', requires overriding defaults in both
`configure' and `make':
configure --prefix=`/texmf' --datadir=`/texmf'
make texmf=`/texmf'
* You can compile on multiple architectures simultaneously either by
building symbolic link trees with the `lndir' script from the X11
distribution, or with the `--srcdir' option:
configure --srcdir=SRCDIR
* If you are installing binaries for multiple architectures into a
single hierarchy, you will probably want to override the default
`bin' and `lib' directories, something like this:
configure --prefix=TEXMF --datadir=TEXMF \
--bindir=TEXMF/ARCH/bin --libdir=TEXMF/ARCH/lib
make texmf=TEXMF
(Unless you make provisions for architecture-specific files in
other ways, e.g., with Depot or an automounter.)
* To compile with optimization (to compile without debugging, remove
the `-g'):
env CFLAGS="-g -O" sh configure ...
For a potential problem if you optimize, see *Note TeX or
Metafont failing: TeX or Metafont failing.
File: kpathsea.info, Node: Shared library, Prev: configure scenarios, Up: Running configure
Shared library
..............
You can compile Kpathsea as a shared library on a few systems, by
specifying the option `--enable-shared' when you run `configure'.
The main advantage in doing this is that the executables can then
share the code, thus decreasing memory and disk space requirements.
On some systems, you can record the location of shared libraries in a
binary, usually by giving certain options to the linker. Then
individual users do not need to set their system's environment variable
(e.g., `LD_LIBRARY_PATH') to find shared libraries. If you want to do
this, you will need to add the necessary options to `LDFLAGS' yourself;
for example, on Solaris, include something like `-R${prefix}/lib', on
IRIX or Linux, use `-rpath${prefix}/lib'. (Unfortunately, making this
happen by default is very difficult, because of interactions with an
existing installed shared library.)
Currently, shared library support is implemented only on Linux, SunOS
4 (Solaris 1), SunOS 5 (Solaris 2), IRIX 5, and IRIX 6. If you're
interested and willing in adding support for other systems, please see
the `configure' mode in the `klibtool' script, especially the
host-specific case statement around line 250.
File: kpathsea.info, Node: Running make, Next: Installing files, Prev: Running configure, Up: Custom installation
Running `make'
--------------
`make' (still in the top-level directory). This also creates the
`texmf.cnf' and `paths.h' files that define the default search paths,
and (by default) the `plain' and `latex' TeX formats.
You can override directory names and other values at `make'-time.
`make/paths.make' lists the variables most commonly reset. For
example, `make default_texsizes=600' changes the list of fallback
resolutions.
You can also override each of `configure''s environment variables
(*note configure environment::.). The Make variables have the same
names.
Finally, you can supply additional options via the following
variables. (`configure' does not use these.)
`XCPPFLAGS'
`XDEFS'
Preprocessor options.
`XCFLAGS'
Compiler options.
`XLDFLAGS'
Loader options (included at beginning of link commands).
`XLOADLIBES'
More loader options (included at end of link commands).
`XMAKEARGS'
Additional Make arguments passed to all sub-`make''s. You may need
to include assignments to the other variables here via `XMAKEARGS';
for example: `make XMAKEARGS="CFLAGS=-O XDEFS=-DA4"'.
It's generally a bad idea to use a different compiler (`CC') or
libraries (`LIBS') for compilation than you did for configuration,
since the values `configure' determined may then be incorrect.
Adding compiler options to change the "universe" you are using
(typically BSD vs. system V) is generally a cause of trouble. It's
best to use the native environment, whatever that is; `configure' and
the software usually adapt best to that. In particular, under Solaris
2.x, you should not use the BSD-compatibility library (`libucb') or
include files (`ucbinclude').
If you want to use the Babel LaTeX package for support of non-English
typesetting, you need to modify some files before making the LaTeX
format. See the file `install.txt' in the Babel distribution.

should add a line (you choose where) to the file `dir' in your
`$(infodir)' directory. Sample text for this is given near the top of
the Texinfo source files (`kpathsea/kpathsea.texi',
`dvipsk/dvips.texi', and `web2c/doc/web2c.texi'). If you have a recent
version of the GNU Texinfo distribution installed
(`ftp://prep.ai.mit.edu/pub/gnu/texinfo-3.9.tar.gz' or later), this
should happen automatically.
On the offchance that this is your first Info installation, the `dir'
file I use is included in the distribution as `etc/dir-example'.
You may wish to use one of the following targets, especially if you
are installing on multiple architectures:
* `make install-exec' to install in architecture-dependent
directories, i.e., ones that depend on the `$(exec_prefix)' Make
variable. This includes links to binaries, libraries, etc., not
just "executables".
* `make install-data' to install in architecture-independent
directories, such as documentation, configuration files, pool
files, etc.
If you use the Andrew File System, the normal path (e.g., PREFIX/bin)
only gets you to a read-only copy of the files, and you must specify a
different path for installation. The best way to do this is by setting
the `prefix' variable on the `make' command line. The sequence becomes
something like this:
configure --prefix=/whatever
make
make install prefix=/afs/.SYSTEM.NAME/system/1.3/@sys/whatever
With AFS, you will definitely want to use relative filenames in
`ls-R' (*note Filename database::.), not absolute filenames. This is
done by default, but check anyway.
File: kpathsea.info, Node: Cleaning up, Next: Filename database generation, Prev: Installing files, Up: Custom installation
Cleaning up
-----------
The basic command is `make distclean'. This removes all files created
by the build.
Alternatively,
* `make mostlyclean' if you intend to compile on another
architecture. For Web2C, since the generated C files are portable,
they are not removed. If the `lex' vs. `flex' situation is going
to be different on the next machine, `rm web2c/lex.yy.c'.
* `make clean' to remove files created by compiling, but leave
configuration files and Makefiles.
* `make maintainer-clean' to remove everything that the Makefiles can
rebuild. This is more than `distclean' removes, and you should
only use it if you are thoroughly conversant with (and have the
necessary versions of) Autoconf.
* `make extraclean' to remove other junk, e.g., core files, log
files, patch rejects. This is independent of the other `clean'
targets.
File: kpathsea.info, Node: Filename database generation, Next: mktex scripts, Prev: Cleaning up, Up: Custom installation
Filename database generation
----------------------------
You will probably want to set up a `cron' entry on the appropriate
machine(s) to rebuild the filename database nightly or so, as in:
0 0 * * * cd TEXMF && /BINDIR/mktexlsr
*Note Filename database::.
Although the `mktex...' scripts make every effort to add newly-created
files on the fly, it can't hurt to make sure you get a fresh version
every so often.
File: kpathsea.info, Node: mktex scripts, Next: Installation testing, Prev: Filename database generation, Up: Custom installation
`mktex' scripts
---------------
If Kpathsea cannot otherwise find a file, for some file types it is
configured by default to invoke an external program to create it
dynamically (*note mktex configuration::.). This is most useful for
fonts (bitmaps, TFM's, and arbitrarily-sizable Metafont sources such as
the Sauter and EC fonts), since any given document can use fonts never
before referenced. Trying to build all fonts in advance is therefore
impractical, if not impossible.
The script is passed the name of the file to create and possibly other
arguments, as explained below. It must echo the full pathname of the
file it created (and nothing else) to standard output; it can write
diagnostics to standard error.
* Menu:
* mktex configuration::
* mktex script names::
* mktex script arguments::
File: kpathsea.info, Node: mktex configuration, Next: mktex script names, Up: mktex scripts
`mktex' configuration
.....................
The following file types can run an external program to create missing
files: `pk', `tfm', `mf', `tex'; the scripts are named `mktexpk',
`mktextfm', `mktexmf', and `mktextex'.
In the absence of `configure' options specifying otherwise,
everything but `mktextex' will be enabled by default. The `configure'
options to change the defaults are:
--without-mktexmf-default
--without-mktexpk-default
--without-mktextfm-default
--with-mktextex-default
The `configure' setting is overridden if the environment variable or
configuration file value named for the script is set; e.g., `MKTEXPK'
(*note mktex script arguments::.).
As distributed, all the scripts source a file `texmf/web2c/mktex.cnf'
if it exists, so you can override various defaults. See `mktex.opt',
for instance, which defines the default mode, resolution, some special
directory names, etc. If you prefer not to change the distributed
scripts, you can simply create `mktex.cnf' with the appropriate
definitions (you do not need to create it if you have nothing to put in
it). `mktex.cnf' has no special syntax; it's an arbitrary Bourne shell
script. The distribution contains a sample `mktex.cnf' for you to copy
and modify as you please (it is not installed anywhere).
In addition, you can configure a number of features with the
`MT_FEATURES' variable, which you can define:
* in `mktex.opt', as just mentioned;
* by editing the file `mktex.opt', either before `make install' (in
the source hierarchy) or after (in the installed hierarchy);
* or in the environment.
If none of the options below are enabled, `mktexpk', `mktextfm', and
`mktexmf' follow the following procedure to decide where fonts should
be installed. Find the tree where the font's sources are, and test the
permissions of the `fonts' directory of that tree to determine whether
it is writable. If it is, put the files in the tree in appropriate
locations. If it isn't writable, see whether the tree is a system tree
(named in `SYSTEXMF'). If so, the `VARTEXFONTS' tree is used. In all
other cases the working directory is used.
The `appendonlydir' option is enabled by default.
`appendonlydir'
Tell `mktexdir' to create directories append-only, i.e., set their
sticky bit (*note Mode Structure: (fileutils)Mode Structure.).
This feature is silently ignored on non-Unix platforms (e.g.
Windows/NT and MS-DOS) which don't support similar functionality.
This feature is enabled by default.
`dosnames'
Use 8.3 names; e.g., `dpi600/cmr10.pk' instead of `cmr10.600pk'.
Note that this feature only affects filenames that would otherwise
clash with other TeX-related filenames; `mktex' scripts do nothing
about filenames which exceed the 8+3 MS-DOS limits but remain
unique when truncated (by the OS) to these limits, and nether do
the scripts care about possible clashes with files which aren't
related with TeX. For example, `cmr10.600pk' would clash with
`cmr10.600gf' and is therefore changed when `dosnames' is in
effect, but `mf.pool' and `mp.base' don't clash with any
TeX-related files and are therefore unchanged.
This feature is turned on by default on MS-DOS. If you do not wish
`dosnames' to be set on an MS-DOS platform, you need to set the
`MT_FEATURES' environment variable to a value that doesn't include
`dosnames'. You can also change the default setting by editing
`mktex.opt', but only if you use the `mktex' shell scripts; the
emulation programs don't consult `mktex.opt'.
`fontmaps'
Instead of deriving the location of a font in the destination tree
from the location of the sources, the aliases and directory names
from the Fontname distribution are used. (*note Introduction:
(fontname)Top.).
`nomode'
Omit the directory level for the mode name; this is fine as long as
you generate fonts for only one mode.
`stripsupplier'
Omit the font supplier name directory level.
`striptypeface'
Omit the font typeface name directory level.
`strip'
Omit the font supplier and typeface name directory levels. This
feature is deprecated in favour of `stripsupplier' and
`striptypeface'.
`varfonts'
When this option is enabled, fonts that would otherwise be written
in system texmf tree go to the `VARTEXFONTS' tree instead. The
default value in `kpathsea/Makefile.in' is `/var/tmp/texfonts'.
The `Linux File System Standard' recommends `/var/tex/fonts'.
The `varfonts' setting in `MT_FEATURES' is overridden by the
`USE_VARTEXFONTS' environment variable: if set to `1', the feature
is enabled, and if set to `0', the feature is disabled.
File: kpathsea.info, Node: mktex script names, Next: mktex script arguments, Prev: mktex configuration, Up: mktex scripts
`mktex' script names
....................
The following table shows the default name of the script for each
possible file types. (The source is the variable `kpse_make_specs' in
`kpathsea/tex-make.c'.)
`mktexpk'
Glyph fonts.
`mktextex'
TeX input files.
`mktexmf'
Metafont input files.
`mktextfm'
TFM files.
These names are overridden by an environment variable specific to the
program--for example, `DVIPSMAKEPK' for Dvipsk.
If a `mktex...' script fails, the invocation is appended to a file
`missfont.log' (by default) in the current directory. You can then
execute the log file to create the missing files after fixing the
problem.
If the current directory is not writable and the environment variable
or configuration file value `TEXMFOUTPUT' is set, its value is used.
Otherwise, nothing is written. The name `missfont.log' is overridden
by the `MISSFONT_LOG' environment variable or configuration file value.
File: kpathsea.info, Node: mktex script arguments, Prev: mktex script names, Up: mktex scripts
`mktex' script arguments
........................
The first argument to a `mktex' script is always the name of the file
to be created.
In the default `mktexpk' implementation, additional arguments may
also be passed:
`--dpi NUM'
Sets the resolution of the generated font to NUM.
`--mfmode NAME'
Sets the Metafont mode to NAME.
`--bdpi NUM'
Sets the the "base dpi" for the font. This must match the mode
being used.
`--mag STRING'
A "magstep" string suitable for the Metafont `mag' variable. This
must match the combination of BDPI and DPI being used.
`--destdir STRING'
A directory name. If the directory is absolute, it is used as-is.
Otherwise, it is appended to the root destination directory set in
the script.

Installation testing
--------------------
Besides the tests listed in *Note Simple installation::, you can try
running `make check'. This includes the torture tests (trip, trap, and
mptrap) that come with Web2c (*note Triptrap: (web2c)Triptrap.).
File: kpathsea.info, Node: Security, Next: TeX directory structure, Prev: Custom installation, Up: Installation
Security
========
None of the programs in the TeX system require any special system
privileges, so there's no first-level security concern of people gaining
illegitimate root access.
A TeX document, however, can write to arbitrary files, e.g.,
`~/.rhosts', and thus an unwitting user who runs TeX on a random
document is vulnerable to a trojan horse attack. This loophole is
closed by default, but you can be permissive if you so desire in
`texmf.cnf'. *Note tex invocation: (web2c)tex invocation. MetaPost has
the same issue.
Dvips, Xdvi, and TeX can also execute shell commands under some
circumstances. To disable this, see the `-R' option in *Note Option
details: (dvips)Option details, the xdvi man page, and *Note tex
invocation: (web2c)tex invocation, respectively.
Another security issue arises because it's very useful--almost
necessary--to make arbitrary fonts on user demand with `mktexpk' and
friends. Where do these files get installed? By default, the
`mktexpk' distributed with Kpathsea assumes a world-writable `/var/tmp'
directory; this is a simple and convenient approach, but it may not
suit your situation because it means that a local cache of fonts is
created on every machine.
To avoid this duplication, many people consider a shared, globally
writable font tree desirable, in spite of the potential security
problems. To do this you should change the value of `VARTEXFONTS' in
`texmf.cnf' to refer to some globally known directory. *Note mktex
configuration::.
The first restriction you can apply is to make newly-created
directories under `texmf' be append-only with an option in `mktex.cnf'.
*Note mktex configuration::.
Another approach is to establish a group (or user) for TeX files,
make the `texmf' tree writable only to that group (or user), and make
`mktexpk' et al. setgid to that group (or setuid to that user). Then
users must invoke the scripts to install things. (If you're worried
about the inevitable security holes in scripts, then you could write a
C wrapper to exec the script.)
The `mktex...' scripts install files with the same read and write
permissions as the directory they are installed in. The executable,
sgid, suid, and sticky bits are always cleared.
Any directories created by the `mktex...' scripts have the same
permissions as their parent directory, unless the `appendonlydir'
feature is used, in which case the sticky bit is always set.

TeX directory structure
=======================
This section describes the default installation hierarchy of the
distribution. It conforms to both the GNU coding standards and the TeX
directory structure (TDS) standard. For rationale and further
explanation, please see those documents. The GNU standard is available
as `ftp://prep.ai.mit.edu/pub/gnu/standards/standards.texi' and
mirrors. The TDS document is available from `CTAN:/tex-archive/tds'
(*note unixtex.ftp::.).
You can change the default paths in many ways (*note Changing search
paths::.). One common desire is to put everything (binaries and all)
under a single top-level directory such as `/usr/local/texmf' or
`/opt/texmf'--in the terms used below, make PREFIX and TEXMF the same.
For specific instructions on doing that, see *Note configure
scenarios::.
Here is a skeleton of the default directory structure, extracted from
the TDS document:
PREFIX/ installation root (`/usr/local' by default)
bin/ executables
man/ man pages
include/ C header files
info/ GNU info files
lib/ libraries (`libkpathsea.*')
share/ architecture-independent files
texmf/ TDS root

dvips/ `.pro', `.ps', `psfonts.map'
fonts/ font-related files
TYPE/ file type (e.g., `tfm', `pk')
MODE/ type of output device (types `pk' and `gf' only)
SUPPLIER/ name of a font supplier (e.g., `public')
TYPEFACE/ name of a typeface (e.g., `cm')
dpiNNN/ font resolution (types `pk' and `gf' only)
metafont/ Metafont (non-font) input files
base/ base distribution (e.g., `plain.mf')
misc/ single-file packages (e.g., `modes.mf')
PKG/ name of a package (e.g., `mfpic')
metapost/ MetaPost input files
base/ base distribution (e.g., `plain.mp')
misc/ single-file packages
PKG/ name of a package
support/ support files for MetaPost-related utilities (e.g., `trfonts.map')
mft/ `MFT' inputs (e.g., `plain.mft')
tex/ TeX input files
FORMAT/ name of a format (e.g., `plain')
base/ base distribution for FORMAT (e.g., `plain.tex')
misc/ single-file packages (e.g., `webmac.tex')
local/ local additions to or local configuration files for FORMAT
PKG/ name of a package (e.g., `graphics', `mfnfss')
generic/ format-independent packages
hyphen/ hyphenation patterns (e.g., `hyphen.tex')
images/ image input files (e.g., Encapsulated PostScript)
misc/ single-file format-independent packages (e.g., `null.tex').
PKG/ name of a package (e.g., `babel')
web2c/ implementation-dependent files (`.pool', `.fmt', `texmf.cnf', etc.)

Following are general instructions for Unix or other sites who wish to
acquire the Web2c distribution, (plain) TeX, LaTeX (2e), BibTeX,
Metafont, MetaPost, DVI processors for the X window system, PostScript,
the PCL language in the HP LaserJet, and related programs. They are
oriented towards building from the original sources, though some
information on alternative packages is included in the last section.
See also `http://www.tug.org/web2c', the Web2c and Kpathsea home page.

Electronic distribution
-----------------------
In many places we refer to CTAN:. This is *both* a host name and a
directory name. Here are some primary locations:
`ftp://ctan.tug.org/tex-archive' (California, USA)
`ftp://ftp.dante.de/tex-archive' (Germany)
`ftp://ftp.tex.ac.uk/tex-archive' (England)
CTAN has many mirrors worldwide; see the top-level file
`README.mirrors' from one of the sites above, or finger
<[email protected]>, or see `http://www.tug.org/CTAN.sites'. A list
current as of the time of distribution is in the top-level file
`./MIRROR'.
You can also access CTAN via the World Wide Web, Gopher, electronic
mail, or NFS. The same `README.mirrors' file explains how.
You will need to retrieve some or all of the following archives,
depending on your needs (don't forget to set binary mode for file
transfers):
`CTAN:/systems/web2c/texmflib.tar.gz'
A basic collection of fonts (TFM files only) and macro packages
(including Texinfo and LaTeX 2e). It unpacks into `texmf/'; if
you change the structure of this hierarchy, you will also have to
change the default search paths (*note Changing search paths::.).
It is required unless you already have these files, in which case
you should change the default paths as necessary to find them.
There are other packages of library files, `etexlib.tar.gz',
`omegalib.tar.gz', and `pdftexlib.tar.gz', that are required as
well if you install e-TeX, Omega, or pdfTeX respectively.
`CTAN:/systems/web2c/web.tar.gz'
The original WEB source files, written mostly by Don Knuth.
Required unless you already have this `web' version. (The WEB
sources change irregularly with respect to Web2c itself.) Unpacks
into `web2c-VERSION'.
`CTAN:/systems/web2c/web2c.tar.gz'
The Web2c system. Required. Also unpacks into `web2c-VERSION'.
`CTAN:/systems/web2c/web2c-etex.tar.gz'
Additions to the Web2c system for building e-TeX. Optional. Also
unpacks into `web2c-VERSION'.
`CTAN:/systems/web2c/web2c-omega.tar.gz'
Additions to the Web2c system for building Omega. Optional. Also
unpacks into `web2c-VERSION'.
`CTAN:/systems/web2c/web2c-pdftex.tar.gz'
Additions to the Web2c system for building pdfTeX. Optional. Also
unpacks into `web2c-VERSION'.
`CTAN:/systems/web2c/texk.tar.gz'
The web and web2c sources, plus the additions for web2c, plus the
dvi drivers mentioned below, plus extra dvi drivers and tools not
packaged separately. Recommended if you want to build a complete
system. Unpacks into `texk-VERSION'.
`CTAN:/dviware/dvipsk/dvipsk.tar.gz'
DVI-to-PostScript translator. Unpacks into `dvipsk-VERSION'.
Optional.
`CTAN:/dviware/xdvik/xdvik.tar.gz'
X window system DVI previewer. Unpacks into `xdvik-VERSION'.
Optional.
`CTAN:/dviware/dviljk/dviljk.tar.gz'
DVI-to-PCL (HP LaserJet) translator. Unpacks into
`dviljk-VERSION'. Optional.
All that said, the originating host for the software above is
`ftp.tug.org'. You can retrieve these distributions (but not much
else) from the `tex/' directory on that host.

CD-ROM distribution
-------------------
Numerous organizations distribute various TeX CD-ROM's:
* TUG, UK TUG, and GUTenberg (French-speaking TeX user group)
collaborated to produce the `TeX Live' CD-ROM, based on teTeX,
which in turn is based on Web2c; email <[email protected]> or
see `http://www.tug.org/tex-live.html'.
* Dante (the German-speaking TeX user group) has produced a CD-ROM.
See `http://www.dante.de/dante/DANTE-CTAN-CD-ROM.html', and
`http://www.dante.de/tex-informationen/CD-ROMs.html' for
information about TeX CD's in general. Both are in German.
* The Free Software Foundation's `Source Code CD-ROM' contains the
minimal TeX source distribution described in the previous section
(i.e., enough to print GNU documentation); email
<[email protected]>.
* The Gateway! CD-ROM set contains a runnable NetBSD/Amiga
distribution and sources; see
`http://www.netbsd.org/Sites/cdroms.html'.
* The InfoMagic CD-ROM is a copy of CTAN (see previous section); see
`http://www.infomagic.com'.
* NTG (Dutch-speaking TeX user group) produced the 4allTeX CD-ROM;
email <[email protected]>, or see `http://www.ntg.nl/4allcd/'.
This is a runnable system.
* The Prime Time TeXcetera CD-ROM is also a copy of CTAN; email
<[email protected]> or see `http://www.ptf.com/ptf/'.
* Walnut Creek's TeX CD-ROM is also a copy of CTAN; email
<[email protected]> or see `http://www.cdrom.com:/titles/tex.html'.
* Most Linux distributions include some TeX package based on Web2c;
see the Linux documentation file `Distribution-HOWTO' for a
comparison of Linux distributions, available (for example) via
`http://www.linux.org'.
If you know of additional TeX CD-ROM distributions to add to this
list, please inform <[email protected]>.

Other TeX packages
------------------
Many other TeX implementations are available in `CTAN:/systems',
including ready-to-run distributions for Unix, Amiga, Acorn, VMS,
Macintosh, DOS, and Windows (in various forms). Although Web2c has
support in the source code for many operating systems, and in fact some
of the other distributions are based on it, it's unlikely to work as
distributed on anything but Unix. (Please contribute improvements!)
The Unix distribution alluded to above is the teTeX distribution.
This includes both complete sources and precompiled binaries for many
popular Unix variants, including Linux. It is based on Web2c, and
contains many other TeX-related programs as well.
The host labrea.stanford.edu is the original source for the files for
which Donald Knuth is directly responsible: `tex.web', `plain.tex',
etc. However, unless you want to build your TeX library tree ab initio,
it is more reliable and less work to retrieve these files as part of
the above packages. In any case, labrea is not the canonical source for
anything except what was created by Stanford TeX project, so do not
rely on all the files available at that ftp site being up-to-date.

Bug checklist
-------------
Before reporting a bug, please check below to be sure it isn't already
known (*note Common problems::.).
Bug reports should be sent via electronic mail to
<[email protected]>, or by postal mail to 135 Center Hill Road /
Plymouth, MA 02360 / USA.
The general principle is that a good bug report includes all the
information necessary for reproduction. Therefore, to enable
investigation, your report should include the following:
* The version number(s) of the program(s) involved, and of Kpathsea
itself. You can get the former by giving a sole option `--version'
to the program, and the latter by running `kpsewhich --version'.
The `NEWS' and `ChangeLog' files also contain the version number.
* The hardware, operating system (including version number),
compiler, and `make' program you are using (the output of `uname
-a' is a start on the first two, though often incomplete). If the
bug involves the X window system, include X version and supplier
information as well (examples: X11R6 from MIT; X11R4 from HP;
OpenWindows 3.3 bundled with SunOS 4.1.4).
* Any options you gave to `configure'. This is recorded in the
`config.status' files.
If you are reporting a bug in `configure' itself, it's probably
system-dependent, and it will be unlikely the maintainers can do
anything useful if you merely report that thus-and-such is broken.
Therefore, you need to do some additional work: for some bugs, you
can look in the file `config.log' where the test that failed should
appear, along with the compiler invocation and source program in
question. You can then compile it yourself by hand, and discover
why the test failed. Other `configure' bugs do not involve the
compiler; in that case, the only recourse is to inspect the
`configure' shell script itself, or the Autoconf macros that
generated `configure'.
* The log of all debugging output, if the bug is in path searching.
You can get this by setting the environment variable
`KPATHSEA_DEBUG' to `-1' before running the program. Please look
at the log yourself to make sure the behavior is really a bug
before reporting it; perhaps "old" environment variable settings
are causing files not to be found, for example.
* The contents of any input files necessary to reproduce the bug.
For bugs in DVI-reading programs, for example, this generally
means a DVI file (and any EPS or other files it uses)--TeX source
files are helpful, but the DVI file is necessary, because that's
the actual program input.
GNU `shar', available from `ftp://prep.ai.mit.edu/pub/gnu' is a
convenient way of packaging multiple (possibly binary) files for
electronic mail. If you feel your input files are too big to send
by email, you can ftp them to `ftp://ftp.tug.org/incoming' (that
directory is writable, but not readable).
* If you are sending a patch (do so if you can!), please do so in
the form of a context diff (`diff -c') against the original
distribution source. Any other form of diff is either not as
complete or harder for me to understand. Please also include a
`ChangeLog' entry.
* If the bug involved is an actual crash (i.e., core dump), it is
easy and useful to include a stack trace from a debugger (I
recommend the GNU debugger GDB, available from
`ftp://prep.ai.mit.edu/pub/gnu'). If the cause is apparent (a
`NULL' value being dereferenced, for example), please send the
details along. If the program involved is TeX or Metafont, and
the crash is happening at apparently-sound code, however, the bug
may well be in the compiler, rather than in the program or the
library (*note TeX or Metafont failing: TeX or Metafont failing.).
* Any additional information that will be helpful in reproducing,
diagnosing, or fixing the bug.

Debugging
---------
Kpathsea provides a number of runtime debugging options, detailed
below by their names and corresponding numeric values. When the files
you expect aren't being found, the thing to do is enable these options
and examine the output.
You can set these with some runtime argument (e.g., `-d') to the
program; in that case, you should use the numeric values described in
the program's documentation (which, for Dvipsk and Xdvik, are different
than those below). It's best to give the `-d' (or whatever) option
first, for maximal output. Dvipsk and Xdvik have additional
program-specific debugging options as well.
You can also set the environment variable `KPATHSEA_DEBUG'; in this
case, you should use the numbers below. If you run the program under a
debugger and set the variable `kpathsea_debug', also use the numbers
below.
In any case, by far the simplest value to use is `-1', which will
turn on all debugging output. This is usually better than guessing
which particular values will yield the output you need.
Debugging output always goes to standard error, so you can redirect it
easily. For example, in Bourne-compatible shells:
dvips -d -1 ... 2>/tmp/debug
It is sometimes helpful to run the standalone Kpsewhich utility
(*note Invoking kpsewhich::.), instead of the original program.
In any case, you can *not* use the *names* below; you must always use
somebody's numbers. (Sorry.) To set more than one option, just sum
the corresponding numbers.
`KPSE_DEBUG_STAT (1)'
Report `stat'(2) calls. This is useful for verifying that your
directory structure is not forcing Kpathsea to do many additional
file tests (*note Slow path searching::., and *note Subdirectory
expansion::.). If you are using an up-to-date `ls-R' database
(*note Filename database::.), this should produce no output unless
a nonexistent file that must exist is searched for.
`KPSE_DEBUG_HASH (2)'
Report lookups in all hash tables: `ls-R' and `aliases' (*note
Filename database::.); font aliases (*note Fontmap::.); and config
file values (*note Config files::.). Useful when expected values
are not being found, e.g.., file searches are looking at the disk
instead of using `ls-R'.
`KPSE_DEBUG_FOPEN (4)'
Report file openings and closings. Especially useful when your
system's file table is full, for seeing which files have been
opened but never closed. In case you want to set breakpoints in a
debugger: this works by redefining `fopen' (`fclose') to be
`kpse_fopen_trace' (`kpse_fclose_trace').
`KPSE_DEBUG_PATHS (8)'
Report general path information for each file type Kpathsea is
asked to search. This is useful when you are trying to track down
how a particular path got defined--from `texmf.cnf', `config.ps',
an environment variable, the compile-time default, etc. This is
the contents of the `kpse_format_info_type' structure defined in
`tex-file.h'.
`KPSE_DEBUG_EXPAND (16)'
Report the directory list corresponding to each path element
Kpathsea searches. This is only relevant when Kpathsea searches
the disk, since `ls-R' searches don't look through directory lists
in this way.
`KPSE_DEBUG_SEARCH (32)'
Report on each file search: the name of the file searched for, the
path searched in, whether or not the file must exist (when drivers
search for `cmr10.vf', it need not exist), and whether or not we
are collecting all occurrences of the file in the path (as with,
e.g., `texmf.cnf' and `texfonts.map'), or just the first (as with
most lookups). This can help you correlate what Kpathsea is doing
with what is in your input file.
`KPSE_DEBUG_VARS (64)'
Report the value of each variable Kpathsea looks up. This is
useful for verifying that variables do indeed obtain their correct
values.
`GSFTOPK_DEBUG (128)'
Activates debugging printout specific to `gsftopk' program.
`MAKETEX_DEBUG (512)'
If you use the optional `mktex' programs instead of the
traditional shell scripts, this will report the name of the site
file (`mktex.cnf' by default) which is read, directories created by
`mktexdir', the full path of the `ls-R' database built by
`mktexlsr', font map searches, `MT_FEATURES' in effect, parameters
from `mktexnam', filenames added by `mktexupd', and some
subsidiary commands run by the programs.
`MAKETEX_FINE_DEBUG (1024)'
When the optional `mktex' programs are used, this will print
additional debugging info from functions internal to these
programs.
Debugging output from Kpathsea is always written to standard error,
and begins with the string `kdebug:'. (Except for hash table buckets,
which just start with the number, but you can only get that output
running under a debugger. See comments at the `hash_summary_only'
variable in `kpathsea/db.c'.)
File: kpathsea.info, Node: Logging, Next: Common problems, Prev: Debugging, Up: Reporting bugs
Logging
-------
Kpathsea can record the time and filename found for each successful
search. This may be useful in finding good candidates for deletion when
your filesystem is full, or in discovering usage patterns at your site.
To do this, define the environment or config file variable
`TEXMFLOG'. The value is the name of the file to append the
information to. The file is created if it doesn't exist, and appended
to if it does.
Each successful search turns into one line in the log file: two words
separated by a space. The first word is the time of the search, as the
integer number of seconds since "the epoch", i.e., UTC midnight 1
January 1970 (more precisely, the result of the `time' system call).
The second word is the filename.
For example, after `setenv TEXMFLOG /tmp/log', running Dvips on
`story.dvi' appends the following lines:
774455887 /usr/local/share/texmf/dvips/config.ps
774455887 /usr/local/share/texmf/dvips/psfonts.map
774455888 /usr/local/share/texmf/dvips/texc.pro
774455888 /usr/local/share/texmf/fonts/pk/ljfour/public/cm/cmbx10.600pk
774455889 /usr/local/share/texmf/fonts/pk/ljfour/public/cm/cmsl10.600pk
774455889 /usr/local/share/texmf/fonts/pk/ljfour/public/cm/cmr10.600pk
774455889 /usr/local/share/texmf/dvips/texc.pro
Only filenames that are absolute are recorded, to preserve some
semblance of privacy.

Common problems
---------------
Here are some common problems with configuration, compilation,
linking, execution, ...
* Menu:
* Unable to find files:: If your program can't find fonts (or whatever).
* Slow path searching:: If it takes forever to find anything.
* Unable to generate fonts:: If mktexpk fails.
* TeX or Metafont failing:: Likely compiler bugs.
* Empty Makefiles:: When configure produces empty makefiles.
* XtStrings:: When _XtStrings is undefined.
* dlopen:: When dlopen is undefined.
* ShellWidgetClass:: For dynamic linking troubles under OpenWindows.
* Pointer combination warnings:: For old compilers that don't grok char *.
File: kpathsea.info, Node: Unable to find files, Next: Slow path searching, Up: Common problems
Unable to find files
....................
If a program complains it cannot find fonts (or other input files),
any of several things might be wrong. In any case, you may find the
debugging options helpful. *Note Debugging::.
* Perhaps you simply haven't installed all the necessary files; the
basic fonts and input files are distributed separately from the
programs. *Note unixtex.ftp::.
* You have (perhaps unknowingly) told Kpathsea to use search paths
that don't reflect where the files actually are. One common cause
is having environment variables set from a previous installation,
thus overriding what you carefully set in `texmf.cnf' (*note
Supported file formats::.). System `/etc/profile' or other files
such may be the culprit.
* Your files reside in a directory that is only pointed to via a
symbolic link, in a leaf directory and is not listed in `ls-R'.
Unfortunately, Kpathsea's subdirectory searching has an
irremediable deficiency: If a directory D being searched for
subdirectories contains plain files and symbolic links to other
directories, but no true subdirectories, D will be considered a
leaf directory, i.e., the symbolic links will not be followed.
*Note Subdirectory expansion::.
You can work around this problem by creating an empty dummy
subdirectory in D. Then D will no longer be a leaf, and the
symlinks will be followed.
The directory immediately followed by the `//' in the path
specification, however, is always searched for subdirectories,
even if it is a leaf. Presumably you would not have asked for the
directory to be searched for subdirectories if you didn't want it
to be.
* If the fonts (or whatever) don't already exist, `mktexpk' (or
`mktexmf' or `mktextfm') will try to create them. If these rather
complicated shell scripts fail, you'll eventually get an error
message saying something like `Can't find font FONTNAME'. The best
solution is to fix (or at least report) the bug in `mktexpk'; the
workaround is to generate the necessary fonts by hand with
Metafont, or to grab them from a CTAN site (*note unixtex.ftp::.).
* There is a bug in the library. *Note Reporting bugs::.
File: kpathsea.info, Node: Slow path searching, Next: Unable to generate fonts, Prev: Unable to find files, Up: Common problems
Slow path searching
...................
If your program takes an excessively long time to find fonts or other
input files, but does eventually succeed, here are some possible
culprits:
* Most likely, you just have a lot of directories to search, and that
takes a noticeable time. The solution is to create and maintain a
separate `ls-R' file that lists all the files in your main TeX
hierarchy. *Note Filename database::. Kpathsea always uses `ls-R'
if it's present; there's no need to recompile or reconfigure any
of the programs.
* Your recursively-searched directories (e.g.,
`/usr/local/share/texmf/fonts//'), contain a mixture of files and
directories. This prevents Kpathsea from using a useful
optimization (*note Subdirectory expansion::.).
It is best to have only directories (and perhaps a `README') in the
upper levels of the directory structure, and it's very important
to have *only* files, and no subdirectories, in the leaf
directories where the dozens of TFM, PK, or whatever files reside.
In any case, you may find the debugging options helpful in determining
precisely when the disk or network is being pounded. *Note Debugging::.
File: kpathsea.info, Node: Unable to generate fonts, Next: TeX or Metafont failing, Prev: Slow path searching, Up: Common problems
Unable to generate fonts
........................
This can happen if either `mktexpk' hasn't been installed properly,
or if the local installation of Metafont isn't correct.
If `mf' is a command not found by `mktexpk', then you need to install
Metafont (*note unixtex.ftp::.).
If Metafont runs, but generates fonts at the wrong resolution, you
need to be sure the `M' and `D' lines in your Dvips configuration file
match (*note Config files: (dvips)Config files.). For example, if
`mktexpk' is generating 300dpi fonts, but you need 600dpi fonts, you
should have:
M ljfour
D 600
If Metafont runs but generates fonts at a resolution of 2602dpi (and
prints out the name of each character as well as just a character
number, and maybe tries to display the characters), then your Metafont
base file probably hasn't been made properly. (It's using the default
`proof' mode, instead of an actual device mode.) To make a proper
`plain.base', assuming the local mode definitions are contained in a
file `modes.mf', run the following command (assuming Unix):
inimf "plain; input modes; dump"
Then copy the `plain.base' file from the current directory to where the
base files are stored on your system (`/usr/local/share/texmf/web2c' by
default), and make a link (either hard or soft) from `plain.base' to
`mf.base' in that directory. *Note inimf invocation: (web2c)inimf
invocation.
File: kpathsea.info, Node: TeX or Metafont failing, Next: Empty Makefiles, Prev: Unable to generate fonts, Up: Common problems
TeX or Metafont failing
.......................
If TeX or Metafont get a segmentation fault or otherwise fail while
running a normal input file, the problem is usually a compiler bug
(unlikely as that may sound). Even if the trip and trap tests are
passed, problems may lurk. Optimization occasionally causes trouble in
programs other than TeX and Metafont themselves, too.
Insufficient swap space may also cause core dumps or other erratic
behavior.
For a workaround, if you enabled any optimization flags, it's best to
omit optimization entirely. In any case, the way to find the facts is
to run the program under the debugger and see where it's failing.
Also, if you have trouble with a system C compiler, I advise trying
the GNU C compiler. And vice versa, unfortunately; but in that case I
also recommend reporting a bug to the GCC mailing list; see *Note Bugs:
(gcc)Bugs.
To report compiler bugs effectively requires perseverance and
perspicacity: you must find the miscompiled line, and that usually
involves delving backwards in time from the point of error, checking
through TeX's (or whatever program's) data structures. Things are not
helped by all-too-common bugs in the debugger itself. Good luck.
One known cause of trouble is the way arrays are handled. Some of the
Pascal arrays have a lower index other than 0, and the C code will take
the pointer to the allocated memory, subtract the lower index, and use
the resulting pointer for the array. While this trick often works, ANSI
C doesn't guarantee that it will. It it known to fail on HP-UX 10
mchines when the native compiler is used, unless the `+u' compiler
switch was specified. Using GCC will work on this platform as well.
File: kpathsea.info, Node: Empty Makefiles, Next: XtStrings, Prev: TeX or Metafont failing, Up: Common problems
Empty Makefiles
...............
On some systems (NetBSD, FreeBSD, AIX 4.1, and Mach10), `configure'
may fail to properly create the Makefiles. Instead, you get an error
which looks something like this:
prompt$ ./configure
...
creating Makefile
sed: 1: "\\@^ac_include make/pat ...": \ can not be used as a string delimiter
So far as I know, the bug here is in `/bin/sh' on these systems. I
don't have access to a machine running any of them, so if someone can
find a workaround that avoids the quoting bug, I'd be most grateful.
(Search for `ac_include' in the `configure' script to get to the
problematic code.)
It should work to run `bash configure', instead of using `/bin/sh'.
You can get Bash from `ftp://prep.ai.mit.edu/pub/gnu' and mirrors.
Another possible cause (reported for NeXT) is a bug in the `sed'
command. In that case the error may look like this:
Unrecognized command: \@^ac_include make/paths.make@r make/paths.make
In this case, installing GNU `sed' should solve the problem. You can
get GNU `sed' from the same places as Bash.
File: kpathsea.info, Node: XtStrings, Next: dlopen, Prev: Empty Makefiles, Up: Common problems
`XtStrings'
...........
You may find that linking X programs results in an error from the
linker that `XtStrings' is undefined, something like this:
gcc -o virmf ...
.../x11.c:130: undefined reference to `XtStrings'
This generally happens because of a mismatch between the X include
files with which you compiled and the X libraries with which you linked;
often, the include files are from MIT and the libraries from Sun.
The solution is to use the same X distribution for compilation and
linking. Probably `configure' was unable to guess the proper
directories from your installation. You can use the `configure'
options `--x-includes=PATH' and `--x-libraries=PATH' to explicitly
specify them.
File: kpathsea.info, Node: dlopen, Next: ShellWidgetClass, Prev: XtStrings, Up: Common problems
`dlopen'
........
(This section adapted from the file `dlsym.c' in the X distribution.)
The `Xlib' library uses the standard C function `wcstombs'. Under
SunOS 4.1, `wcstombs' uses the `dlsym' interface defined in `libdl.so'.
Unfortunately, the SunOS 4.1 distribution does not include a static
`libdl.a' library.
As a result, if you try to link an X program statically under SunOS,
you may get undefined references to `dlopen', `dlsym', and `dlclose'.
One workaround is to include these definitions when you link:
void *dlopen() { return 0; }
void *dlsym() { return 0; }
int dlclose() { return -1; }
These are contained in the `dlsym.c' file in the MIT X distribution.
File: kpathsea.info, Node: ShellWidgetClass, Next: Pointer combination warnings, Prev: dlopen, Up: Common problems
`ShellWidgetClass'
..................
(This section adapted from the comp.sys.sun.admin FAQ.)
If you are linking with Sun's OpenWindows libraries in SunOS 4.1.x,
you may get undefined symbols `_get_wmShellWidgetClass' and
`_get_applicationShellWidgetClass' when linking. This problem does not
arise using the standard MIT X libraries under SunOS.
The cause is bugs in the `Xmu' shared library as shipped from Sun.
There are several fixes:
* Install the free MIT distribution from `ftp.x.org' and mirrors.
* Get the OpenWindows patches listed below.
* Statically link the `Xmu' library into the executable.
* Avoid using `Xmu' at all. If you are compiling Metafont, see *Note
Online Metafont graphics: (web2c)Online Metafont graphics. If you
are compiling Xdvi, see the `-DNOTOOL' option in `xdvik/INSTALL'.
* Ignore the errors. The binary runs fine regardless.
Here is the information for getting the two patches:
Patch ID: 100512-02
Bug ID's: 1086793, 1086912, 1074766
Description: 4.1.x OpenWindows 3.0 `libXt' jumbo patch
Patch ID: 100573-03
Bug ID: 1087332
Description: 4.1.x OpenWindows 3.0 undefined symbols when using shared `libXmu'.
The way to statically link with `libXmu' depends on whether you are
using a Sun compiler (e.g., `cc') or `gcc'. If the latter, alter the
`x_libs' Make variable to include
-static -lXmu -dynamic
If you are using the Sun compiler, use `-Bstatic' and `-Bdynamic'.

Searching overview
==================
A "search path" is a colon-separated list of "path elements", which
are directory names with a few extra frills. A search path can come
from (a combination of) many sources; see below. To look up a file
`foo' along a path `.:/dir', Kpathsea checks each element of the path
in turn: first `./foo', then `/dir/foo', returning the first match (or
possibly all matches).
The "colon" and "slash" mentioned here aren't necessarily `:' and `/'
on non-Unix systems. Kpathsea tries to adapt to other operating
systems' conventions.
To check a particular path element E, Kpathsea first sees if a
prebuilt database (*note Filename database::.) applies to E, i.e., if
the database is in a directory that is a prefix of E. If so, the path
specification is matched against the contents of the database.
If the database does not exist, or does not apply to this path
element, or contains no matches, the filesystem is searched (if this
was not forbidden by the specification with `!!' and if the file being
searched for must exist). Kpathsea constructs the list of directories
that correspond to this path element, and then checks in each for the
file being searched for. (To help speed future lookups of files in the
same directory, the directory in which a file is found is floated to the
top of the directory list.)
The "file must exist" condition comes into play with VF files and
input files read by the TeX `\openin' command. These files may not
exist (consider `cmr10.vf'), and so it would be wrong to search the
disk for them. Therefore, if you fail to update `ls-R' when you
install a new VF file, it will never be found.
Each path element is checked in turn: first the database, then the
disk. If a match is found, the search stops and the result is
returned. This avoids possibly-expensive processing of path
specifications that are never needed on a particular run. (Unless the
search explicitly requested all matches.)
Although the simplest and most common path element is a directory
name, Kpathsea supports additional features in search paths: layered
default values, environment variable names, config file values, users'
home directories, and recursive subdirectory searching. Thus, we say
that Kpathsea "expands" a path element, meaning transforming all the
magic specifications into the basic directory name or names. This
process is described in the sections below. It happens in the same
order as the sections.
Exception to all of the above: If the filename being searched for is
absolute or explicitly relative, i.e., starts with `/' or `./' or
`../', Kpathsea simply checks if that file exists.
Ordinarily, if Kpathsea tries to access a file or directory that
cannot be read, it gives a warning. This is so you will be alerted to
directories or files that accidentally lack read permission (for
example, a `lost+found'). If you prefer not to see these warnings,
include the value `readable' in the `TEX_HUSH' environment variable or
config file value.
This generic path searching algorithm is implemented in
`kpathsea/pathsearch.c'. It is employed by a higher-level algorithm
when searching for a file of a particular type (*note File lookup::.,
and *Note Glyph lookup::).
File: kpathsea.info, Node: Path sources, Next: Path expansion, Prev: Searching overview, Up: Path searching
Path sources
============
A search path can come from many sources. In the order in which
Kpathsea uses them:
1. A user-set environment variable, e.g., `TEXINPUTS'. Environment
variables with an underscore and the program name appended
override; for example, `TEXINPUTS_latex' overrides `TEXINPUTS' if
the program being run is named `latex'.
2. A program-specific configuration file, e.g., an `S /a:/b' line in
Dvips' `config.ps' (*note Config files: (dvips)Config files.).
3. A line in a Kpathsea configuration file `texmf.cnf', e.g.,
`TEXINPUTS=/c:/d' (see below).
4. The compile-time default (specified in `kpathsea/paths.h').
You can see each of these values for a given search path by using the
debugging options (*note Debugging::.).
These sources may be combined via default expansion (*note Default
expansion::.).
* Menu:
* Config files:: Kpathsea's runtime config files (texmf.cnf).
File: kpathsea.info, Node: Config files, Up: Path sources
Config files
------------
As mentioned above, Kpathsea reads "runtime configuration files"
named `texmf.cnf' for search path and other definitions. The search
path used to look for these configuration files is named `TEXMFCNF',
and is constructed in the usual way, as described above, except that
configuration files cannot be used to define the path, naturally; also,
an `ls-R' database is not used to search for them.
Kpathsea reads *all* `texmf.cnf' files in the search path, not just
the first one found; definitions in earlier files override those in
later files. Thus, if the search path is `.:$TEXMF', values from
`./texmf.cnf' override those from `$TEXMF/texmf.cnf'.
While (or instead of) reading this description, you may find it
helpful to look at the distributed `texmf.cnf', which uses or at least
mentions most features. The format of `texmf.cnf' files follows:
* Comments start with `%' and continue to the end of the line.
* Blank lines are ignored.
* A `\' at the end of a line acts as a continuation character, i.e.,
the next line is appended. Whitespace at the beginning of
continuation lines is not ignored.
* Each remaining line must look like
VARIABLE [. PROGNAME] [=] VALUE
where the `=' and surrounding whitespace is optional.
* The VARIABLE name may contain any character other than whitespace,
`=', or `.', but sticking to `A-Za-z_' is safest.
* If `.PROGNAME' is present, the definition only applies if the
program that is running is named (i.e., the last component of
`argv[0]' is) PROGNAME or `PROGNAME.exe'. This allows different
flavors of TeX to have different search paths, for example.
* VALUE may contain any characters except `%' and `@'. (These
restrictions are only necessary because of the processing done on
`texmf.cnf' at build time, so you can stick those characters in
after installation if you have to.) The `$VAR.PROG' feature is
not available on the right-hand side; instead, you must use an
additional variable (see below for example). A `;' in VALUE is
translated to `:' if running under Unix; this is useful to write a
single `texmf.cnf' which can be used under both Unix and NT. (If
you really want `;''s in your filenames, add
`-DALLOW_SEMICOLON_IN_FILENAMES' to `CFLAGS'.)
* All definitions are read before anything is expanded, so you can
use variables before they are defined (like Make, unlike most other
programs).
Here is a configuration file fragment illustrating most of these points:
% TeX input files -- i.e., anything to be found by \input or \openin ...
latex209_inputs = .:$TEXMF/tex/latex209//:$TEXMF/tex//
latex2e_inputs = .:$TEXMF/tex/latex//:$TEXMF/tex//
TEXINPUTS = .:$TEXMF/tex//
TEXINPUTS.latex209 = $latex209_inputs
TEXINPUTS.latex2e = $latex2e_inputs
TEXINPUTS.latex = $latex2e_inputs
Although this format has obvious similarities to Bourne shell
scripts--change the comment character to `#', disallow spaces around
the `=', and get rid of the `.NAME' convention, and it could be run
through the shell. But there seemed little advantage to doing this,
since all the information would have to passed back to Kpathsea and
parsed there anyway, since the `sh' process couldn't affect its
parent's environment.
The implementation of all this is in `kpathsea/cnf.c'.

Path expansion
==============
Kpathsea recognizes certain special characters and constructions in
search paths, similar to that in shells. As a general example:
`~$USER/{foo,bar}//baz' expands to all subdirectories under directories
`foo' and `bar' in $USER's home directory that contain a directory or
file `baz'. These expansions are explained in the sections below.
* Menu:
* Default expansion:: a: or :a or a::b expands to a default.
* Variable expansion:: $foo and ${foo} expand to environment values.
* Tilde expansion:: ~ and ~user expand to home directories.
* Brace expansion:: a{foo,bar}b expands to afoob abarb.
* KPSE_DOT expansion:: . is replaced with $KPSE_DOT if it is defined.
* Subdirectory expansion:: a// and a//b recursively expand to subdirs.
File: kpathsea.info, Node: Default expansion, Next: Variable expansion, Up: Path expansion
Default expansion
-----------------
If the highest-priority search path (*note Path sources::.) contains
an "extra colon" (i.e., leading, trailing, or doubled), Kpathsea
inserts at that point the next-highest-priority search path that is
defined. If that inserted path has an extra colon, the same happens
with the next-highest. (An extra colon in the compile-time default
value has unpredictable results, so installers beware.)
For example, given an environment variable setting
setenv TEXINPUTS /home/karl:
and a `TEXINPUTS' value from `texmf.cnf' of
.:$TEXMF//tex
then the final value used for searching will be:
/home/karl:.:$TEXMF//tex
Since Kpathsea looks for multiple configuration files, it would be
natural to expect that (for example) an extra colon in `./texmf.cnf'
would expand to the path in `$TEXMF/texmf.cnf'. Or, with Dvips'
configuration files, that an extra colon in `config.$PRINTER' would
expand to the path in `config.ps'. This doesn't happen. It's not
clear this would be desirable in all cases, and trying to devise a way
to specify the path to which the extra colon should expand seemed truly
baroque.
Technicality: Since it would be useless to insert the default value in
more than one place, Kpathsea changes only one extra `:' and leaves any
others in place (they will eventually be ignored). Kpathsea checks
first for a leading `:', then a trailing `:', then a doubled `:'.
You can trace this by debugging "paths" (*note Debugging::.).
Default expansion is implemented in the source file
`kpathsea/kdefault.c'.
File: kpathsea.info, Node: Variable expansion, Next: Tilde expansion, Prev: Default expansion, Up: Path expansion
Variable expansion
------------------
`$foo' or `${foo}' in a path element is replaced by (1) the value of
an environment variable `foo' (if defined); (2) the value of `foo' from
`texmf.cnf' (if defined); (3) the empty string.
If the character after the `$' is alphanumeric or `_', the variable
name consists of all consecutive such characters. If the character
after the `$' is a `{', the variable name consists of everything up to
the next `}' (braces may not be nested around variable names).
Otherwise, Kpathsea gives a warning and ignores the `$' and its
following character.
You must quote the $'s and braces as necessary for your shell.
*Shell* variable values cannot be seen by Kpathsea, i.e., ones defined
by `set' in C shells and without `export' in Bourne shells.
For example, given
setenv tex /home/texmf
setenv TEXINPUTS .:$tex:${tex}prev
the final `TEXINPUTS' path is the three directories:
.:/home/texmf:/home/texmfprev
The `.PROGNAME' suffix on variables and `_PROGNAME' on environment
variable names are not implemented for general variable expansions.
These are only recognized when search paths are initialized (*note Path
sources::.).
Variable expansion is implemented in the source file
`kpathsea/variable.c'.
File: kpathsea.info, Node: Tilde expansion, Next: Brace expansion, Prev: Variable expansion, Up: Path expansion
Tilde expansion
---------------
A leading `~' in a path element is replaced by the value of the
environment variable `HOME', or `.' if `HOME' is not set.
A leading `~USER' in a path element is replaced by USER's home
directory from the system `passwd' database.
For example,
setenv TEXINPUTS ~/mymacros:
will prepend a directory `mymacros' in your home directory to the
default path.
As a special case, if a home directory ends in `/', the trailing
slash is dropped, to avoid inadvertently creating a `//' construct in
the path. For example, if the home directory of the user `root' is
`/', the path element `~root/mymacros' expands to just `/mymacros', not
`//mymacros'.
Tilde expansion is implemented in the source file `kpathsea/tilde.c'.
File: kpathsea.info, Node: Brace expansion, Next: KPSE_DOT expansion, Prev: Tilde expansion, Up: Path expansion
Brace expansion
---------------
`x{A:B}y' expands to `xAy:xBy'. For example:
foo/{1:2}/baz
expands to `foo/1/baz:foo/2/baz'. `:' is the path separator on the
current system; e.g., on a DOS system, it's `;'.
Braces can be nested; for example, `x{A:B{1:2}}y' expands to
`xAy:xB1y:xB2y'.
Multiple non-nested braces are expanded from right to left; for
example, `x{A:B}{1:2}y' expands to `x{A:B}1y:x{A:B}2y', which expands
to `xA1y:xB1y:xA2y:xB2:y'.
This feature can be used to implement multiple TeX hierarchies, by
assigning a brace list to `$TEXMF', as mentioned in `texmf.in'.
In old versions of the library you had to use a comma. While this
usage is deprecated, it is still supported for backwards compatibility
with old configurations. The last example could have been written
`x{A,B}{1,2}y'.
Brace expansion is implemented in the source file
`kpathsea/expand.c'. It is a modification of the Bash sources, and is
thus covered by the GNU General Public License, rather than the Library
General Public License that covers the rest of Kpathsea.
File: kpathsea.info, Node: KPSE_DOT expansion, Next: Subdirectory expansion, Prev: Brace expansion, Up: Path expansion
`KPSE_DOT' expansion
--------------------
When `KPSE_DOT' is defined in the environment, it names a directory
that should be considered the current directory for the purpose of
looking up files in the search paths. This feature is needed by the
`mktex...' scripts *Note mktex scripts::, because these change the
working directory. You should not ever define it yourself.
File: kpathsea.info, Node: Subdirectory expansion, Prev: KPSE_DOT expansion, Up: Path expansion
Subdirectory expansion
----------------------
Two or more consecutive slashes in a path element following a
directory D is replaced by all subdirectories of D: first those
subdirectories directly under D, then the subsubdirectories under
those, and so on. At each level, the order in which the directories are
searched is unspecified. (It's "directory order", and definitely not
alphabetical.)
If you specify any filename components after the `//', only
subdirectories which match those components are included. For example,
`/a//b' would expand into directories `/a/1/b', `/a/2/b', `/a/1/1/b',
and so on, but not `/a/b/c' or `/a/1'.
You can include multiple `//' constructs in the path.
`//' at the beginning of a path is ignored; you didn't really want to
search every directory on the system, did you?
I should mention one related implementation trick, which I took from
GNU find. Matthew Farwell suggested it, and David MacKenzie
implemented it.
The trick is that in every real Unix implementation (as opposed to the
POSIX specification), a directory which contains no subdirectories will
have exactly two links (namely, one for `.' and one for `..'). That is
to say, the `st_nlink' field in the `stat' structure will be two.
Thus, we don't have to stat everything in the bottom-level (leaf)
directories--we can just check `st_nlink', notice it's two, and do no
more work.
But if you have a directory that contains a single subdirectory and
500 regular files, `st_nlink' will be 3, and Kpathsea has to stat every
one of those 501 entries. Therein lies slowness.
You can disable the trick by undefining `UNIX_ST_LINK' in
`kpathsea/config.h'. (It is undefined by default except under Unix.)
Unfortunately, in some cases files in leaf directories are `stat''d:
if the path specification is, say, `$TEXMF/fonts//pk//', then files in
a subdirectory `.../pk', even if it is a leaf, are checked. The reason
cannot be explained without reference to the implementation, so read
`kpathsea/elt-dirs.c' (search for `may descend') if you are curious.
And if you can find a way to *solve* the problem, please let me know.
Subdirectory expansion is implemented in the source file
`kpathsea/elt-dirs.c'.
File: kpathsea.info, Node: Filename database, Next: Invoking kpsewhich, Prev: Path expansion, Up: Path searching
Filename database (`ls-R')
==========================
Kpathsea goes to some lengths to minimize disk accesses for searches
(*note Subdirectory expansion::.). Nevertheless, at installations with
enough directories, searching each possible directory for a given file
can take an excessively long time (depending on the speed of the disk,
whether it's NFS-mounted, how patient you are, etc.).
In practice, a font tree containing the standard PostScript and PCL
fonts is large enough for searching to be noticeably slow on typical
systems these days. Therefore, Kpathsea can use an externally-built
"database" file named `ls-R' that maps files to directories, thus
avoiding the need to exhaustively search the disk.
A second database file `aliases' allows you to give additional names
to the files listed in `ls-R'. This can be helpful to adapt to "8.3"
filename conventions in source files.
The `ls-R' and `aliases' features are implemented in the source file
`kpathsea/db.c'.
* Menu:
* ls-R:: The main filename database.
* Filename aliases:: Aliases for those names.
* Database format:: Syntax details of the database file.
File: kpathsea.info, Node: ls-R, Next: Filename aliases, Up: Filename database
`ls-R'
------
As mentioned above, you must name the main filename database `ls-R'.
You can put one at the root of each TeX installation hierarchy you wish
to search (`$TEXMF' by default); most sites have only one hierarchy.
Kpathsea looks for `ls-R' files along the `TEXMFDBS' path, so that
should presumably match the list of hierarchies.
The recommended way to create and maintain `ls-R' is to run the
`mktexlsr' script, which is installed in `$(bindir)' (`/usr/local/bin'
by default). That script goes to some trouble to follow symbolic links
as necessary, etc. It's also invoked by the distributed `mktex...'
scripts.
At its simplest, though, you can build `ls-R' with the command
cd /YOUR/TEXMF/ROOT && ls -LAR ./ >ls-R
presuming your `ls' produces the right output format (see the section
below). GNU `ls', for example, outputs in this format. Also presuming
your `ls' hasn't been aliased in a system file (e.g., `/etc/profile')
to something problematic, e.g., `ls --color=tty'. In that case, you
will have to disable the alias before generating `ls-R'. For the
precise definition of the file format, see *Note Database format::.
Regardless of whether you use the supplied script or your own, you
will almost certainly want to invoke it via `cron', so when you make
changes in the installed files (say if you install a new LaTeX
package), `ls-R' will be automatically updated.
The `-A' option to `ls' includes files beginning with `.' (except
for `.' and `..'), such as the file `.tex' included with the LaTeX
tools package. (On the other hand, *directories* whose names begin
with `.' are always ignored.)
If your system does not support symbolic links, omit the `-L'.
`ls -LAR /YOUR/TEXMF/ROOT' will also work. But using `./' avoids
embedding absolute pathnames, so the hierarchy can be easily
transported. It also avoids possible trouble with automounters or
other network filesystem conventions.
Kpathsea warns you if it finds an `ls-R' file, but the file does not
contain any usable entries. The usual culprit is running plain `ls -R'
instead of `ls -LR ./' or `ls -R /YOUR/TEXMF/ROOT'. Another
possibility is some system directory name starting with a `.' (perhaps
if you are using AFS); Kpathsea ignores everything under such
directories.
Because the database may be out-of-date for a particular run, if a
file is not found in the database, by default Kpathsea goes ahead and
searches the disk. If a particular path element begins with `!!',
however, *only* the database will be searched for that element, never
the disk. If the database does not exist, nothing will be searched.
Because this can surprise users ("I see the font `foo.tfm' when I do an
`ls'; why can't Dvips find it?"), it is not in any of the default
search paths.
File: kpathsea.info, Node: Filename aliases, Next: Database format, Prev: ls-R, Up: Filename database
Filename aliases
----------------
In some circumstances, you may wish to find a file under several
names. For example, suppose a TeX document was created using a DOS
system and tries to read `longtabl.sty'. But now it's being run on a
Unix system, and the file has its original name, `longtable.sty'. The
file won't be found. You need to give the actual file `longtable.sty'
an alias `longtabl.sty'.
You can handle this by creating a file `aliases' as a companion to
the `ls-R' for the hierarchy containing the file in question. (You
must have an `ls-R' for the alias feature to work.)
The format of `aliases' is simple: two whitespace-separated words per
line; the first is the real name `longtable.sty', and second is the
alias (`longtabl.sty'). These must be base filenames, with no
directory components. `longtable.sty' must be in the sibling `ls-R'.
Also, blank lines and lines starting with `%' or `#' are ignored in
`aliases', to allow for comments.
If a real file `longtabl.sty' exists, it is used regardless of any
aliases.
File: kpathsea.info, Node: Database format, Prev: Filename aliases, Up: Filename database
Database format
---------------
The "database" read by Kpathsea is a line-oriented file of plain
text. The format is that generated by GNU (and most other) `ls'
programs given the `-R' option, as follows.
* Blank lines are ignored.
* If a line begins with `/' or `./' or `../' and ends with a colon,
it's the name of a directory. (`../' lines aren't useful,
however, and should not be generated.)
* All other lines define entries in the most recently seen directory.
/'s in such lines will produce possibly-strange results.
* Files with no preceding directory line are ignored.
For example, here's the first few lines of `ls-R' (which totals about
30K bytes) on my system:
bibtex
dvips
fonts
ls-R
metafont
metapost
tex
web2c
./bibtex:
bib
bst
doc

`kpsewhich': Standalone path searching
======================================
The Kpsewhich program exercises the path searching functionality
independent of any particular application. This can also be useful as a
sort of `find' program to locate files in your TeX hierarchies, perhaps
in administrative scripts. It is used heavily in the distributed
`mktex...' scripts.
Synopsis:
kpsewhich OPTION... FILENAME...
The options and filename(s) to look up can be intermixed. Options
can start with either `-' or `--', and any unambiguous abbreviation is
accepted.
* Menu:
* Path searching options:: Changing the mode, resolution, etc.
* Auxiliary tasks:: Path and variable expansion.
* Standard options:: -help and -version.
File: kpathsea.info, Node: Path searching options, Next: Auxiliary tasks, Up: Invoking kpsewhich
Path searching options
----------------------
Kpsewhich looks up each non-option argument on the command line as a
filename, and returns the first file found. There is no option to
return all the files with a particular name (you can run the Unix
`find' utility for that, *note Invoking find: (findutils)Invoking
find.).
Various options alter the path searching behavior:
`--dpi=NUM'
Set the resolution to NUM; this only affects `gf' and `pk'
lookups. `-D' is a synonym, for compatibility with Dvips.
Default is 600.
`--format=NAME'
Set the format for lookup to NAME. By default, the format is
guessed from the filename, with `tex' being used if nothing else
fits. The recognized filename extensions (including any leading
`.') are also allowable NAMEs.
All formats also have a name, which is the only way to specify
formats with no associated suffix. For example, for Dvips
configuration files you can use `--format="dvips config"'. (The
quotes are for the sake of the shell.)
Here's the current list of recognized names and the associated
suffixes. *Note Supported file formats::, for more information on
each of these.

This option and `--path' are mutually exclusive.
`--interactive'
After processing the command line, read additional filenames to
look up from standard input.
`-mktex=FILETYPE'
`-no-mktex=FILETYPE'
Turn on or off the `mktex' script associated with FILETYPE. The
only values that make sense for FILETYPE are `pk', `mf', `tex',
and `tfm'. By default, all are off in Kpsewhich. *Note mktex
scripts::.
`--mode=STRING'
Set the mode name to STRING; this also only affects `gf' and `pk'
lookups. No default: any mode will be found. *Note mktex script
arguments::.
`--must-exist'
Do everything possible to find the files, notably including
searching the disk. By default, only the `ls-R' database is
checked, in the interest of efficiency.
`--path=STRING'
Search along the path STRING (colon-separated as usual), instead
of guessing the search path from the filename. `//' and all the
usual expansions are supported (*note Path expansion::.). This
option and `--format' are mutually exclusive. To output the
complete directory expansion of a path, instead of doing a
one-shot lookup, see `--expand-path' in the following section.
`--progname=NAME'
Set the program name to NAME; default is `kpsewhich'. This can
affect the search paths via the `.PROGNAM' feature in
configuration files (*note Config files::.).
File: kpathsea.info, Node: Auxiliary tasks, Next: Standard options, Prev: Path searching options, Up: Invoking kpsewhich
Auxiliary tasks
---------------
Kpsewhich provides some additional features not strictly related to
path lookup:
* `--debug=NUM' sets the debugging options to NUM. *Note
Debugging::.
* `--expand-braces=STRING' outputs the variable and brace expansion
of STRING. *Note Path expansion::.
* `--expand-var=STRING' outputs the variable expansion of STRING.
For example, the `mktex...' scripts run `kpsewhich
--expand-var='$TEXMF'' to find the root of the TeX system
hierarchy. *Note Path expansion::.
* `--expand-path=STRING' outputs the complete expansion of STRING as
a colon-separated path. This is useful to construct a search path
for a program that doesn't accept recursive subdirectory
specifications.
For one-shot uses of an arbitrary (not built in to Kpathsea) path,
see `--path' in the previous section.
* `--show-path=NAME' shows the path that would be used for file
lookups of file type NAME. Either a filename extension (`pk',
`.vf', etc.) or an integer can be used, just as with `--format',
described in the previous section.
File: kpathsea.info, Node: Standard options, Prev: Auxiliary tasks, Up: Invoking kpsewhich
Standard options

Kpsewhich accepts the standard GNU options:
* `--help' prints a help message on standard output and exits.
* `--version' prints the Kpathsea version number and exits.

TeX support
***********
Although the basic features in Kpathsea can be used for any type of
path searching, it came about (like all libraries) with a specific
application in mind: I wrote Kpathsea specifically for TeX system
programs. I had been struggling with the programs I was using (Dvips,
Xdvi, and TeX itself) having slightly different notions of how to
specify paths; and debugging was painful, since no code was shared.
Therefore, Kpathsea provides some TeX-specific formats and features.
Indeed, many of the supposedly generic path searching features were
provided because they seemed useful in that conTeXt (font lookup,
particularly).
Kpathsea provides a standard way to search for files of any of the
supported file types; glyph fonts are a bit different than all the rest.
Searches are based solely on filenames, not file contents--if a GF file
is named `cmr10.600pk', it will be found as a PK file.
* Menu:
* Supported file formats:: File types Kpathsea knows about.
* File lookup:: Searching for most kinds of files.
* Glyph lookup:: Searching for bitmap fonts.
* Suppressing warnings:: Avoiding warnings via TEX_HUSH.

Supported file formats
======================
Kpathsea has support for a number of file types. Each file type has a
list of environment and config file variables that are checked to define
the search path, and most have a default suffix that plays a role in
finding files (see the next section). Some also define additional
suffixes, and/or a program to be run to create missing files on the fly.
Since environment variables containing periods, such as
`TEXINPUTS.latex', are not allowed on some systems, Kpathsea looks for
environment variables with an underscore, e.g., `TEXINPUTS_latex'
(*note Config files::.).

appending `INPUTS'. Assuming the program is called `foo', this gives
us the following table.

(text files used by `foo') `FOOINPUTS'.
`other binary files'
(binary files used by `foo') `FOOINPUTS'.
If an environment variable by these names are set, the corresponding
`texmf.cnf' definition won't be looked at (unless, as usual, the
environment variable value has an extra `:'). *Note Default
expansion::.
For the font variables, the intent is that:
* `TEXFONTS' is the default for everything.
* `GLYPHFONTS' is the default for bitmap (or, more precisely,
non-metric) files.
* Each font format has a variable of its own.
* Each program has its own font override path as well; e.g.,
`DVIPSFONTS' for Dvipsk. Again, this is for bitmaps, not metrics.

File lookup
===========
This section describes how Kpathsea searches for most files (bitmap
font searches are the exception, as described in the next section).
Here is the search strategy for a file NAME:
1. If the file format defines default suffixes, and the suffix of
NAME name is not already a known suffix for that format, try the
name with each default appended, and use alternative names found
in the fontmaps if necessary. We postpone searching the disk as
long as possible. Example: given `foo.sty', look for `foo.sty.tex'
before `foo.sty'. This is unfortunate, but allows us to find
`foo.bar.tex' before `foo.bar' if both exist and we were given
`foo.bar'.
2. Search for NAME, and if necssary for alternative names found in
the fontmaps. Again we avoid searching the disk if possible.
Example: given `foo', we look for `foo'.
3. If the file format defines a program to invoke to create missing
files, run it (*note mktex scripts::.).
This is implemented in the routine `kpse_find_file' in
`kpathsea/tex-file.c'. You can watch it in action with the debugging
options (*note Debugging::.).

Glyph lookup
============
This section describes how Kpathsea searches for a bitmap font in GF
or PK format (or either) given a font name (e.g., `cmr10') and a
resolution (e.g., 600).
Here is an outline of the search strategy (details in the sections
below) for a file NAME at resolution DPI. The search stops at the
first successful lookup.
1. Look for an existing file NAME.DPIFORMAT in the specified
format(s).
2. If NAME is an alias for a file F in the fontmap file
`texfonts.map', look for F.DPI.
3. Run an external program (typically named `mktexpk') to generate
the font (*note mktex scripts::.)
4. Look for FALLBACK.DPI, where FALLBACK is some last-resort font
(typically `cmr10').
This is implemented in `kpse_find_glyph_format' in
`kpathsea/tex-glyph.c'.
* Menu:
* Basic glyph lookup:: Features common to all glyph lookups.
* Fontmap:: Aliases for fonts.
* Fallback font:: Resolutions and fonts of last resort.

Basic glyph lookup
------------------
When Kpathsea looks for a bitmap font NAME at resolution DPI in a
format FORMAT, it first checks each directory in the search path for a
file `NAME.DPIFORMAT'; for example, `cmr10.600pk'. Kpathsea looks for
a PK file first, then a GF file.
If that fails, Kpathsea looks for `dpiDPI/NAME.FORMAT'; for example,
`dpi600/cmr10.pk'. This is how fonts are typically stored on
filesystems (such as DOS) that permit only three-character extensions.
If that fails, Kpathsea looks for a font with a close-enough DPI.
"Close enough" is defined by the macro `KPSE_BITMAP_TOLERANCE' in
`kpathsea/tex-glyph.h' to be `DPI / 500 + 1'. This is slightly more
than the 0.2% minimum allowed by the DVI standard
(`CTAN:/dviware/driv-standard/level-0').
File: kpathsea.info, Node: Fontmap, Next: Fallback font, Prev: Basic glyph lookup, Up: Glyph lookup
Fontmap
-------
If a bitmap font or metric file is not found with the original name
(see the previous section), Kpathsea looks through any "fontmap" files
for an "alias" for the original font name. These files are named
`texfonts.map' and searched for along the `TEXFONTMAPS'
environment/config file variable. All `texfonts.map' files that are
found are read; earlier definitions override later ones.
This feature is intended to help in two respects:
1. An alias name is limited in length only by available memory, not
by your filesystem. Therefore, if you want to ask for
`Times-Roman' instead of `ptmr', you can (you get `ptmr8r').
2. A few fonts have historically had multiple names: specifically,
LaTeX's "circle font" has variously been known as `circle10',
`lcircle10', and `lcirc10'. Aliases can make all the names
equivalent, so that it no longer matters what the name of the
installed file is; TeX documents will find their favorite name.
The format of fontmap files is straightforward:
* Comments start with `%' and continue to the end of the line.
* Blank lines are ignored.
* Each nonblank line is broken up into a series of "words": a
sequence of non-whitespace characters.
* If the first word is `include', the second word is used as a
filename, and it is searched for and read.
* Otherwise, the first word on each line is the true filename;
* the second word is the alias;
* subsequent words are ignored.
If an alias has an extension, it matches only those files with that
extension; otherwise, it matches anything with the same root, regardless
of extension. For example, an alias `foo.tfm' matches only when
`foo.tfm' is being searched for; but an alias `foo' matches `foo.vf',
`foo.600pk', etc.
As an example, here is an excerpt from the `texfonts.map' in the
Web2c distribution. It makes the circle fonts equivalent and includes
automatically generated maps for most PostScript fonts available from
various font suppliers.
circle10 lcircle10
circle10 lcirc10
lcircle10 circle10
lcircle10 lcirc10
lcirc10 circle10
lcirc10 lcircle10
...
include adobe.map
include apple.map
include bitstrea.map
...
Fontmaps are implemented in the file `kpathsea/fontmap.c'. The
Fontname distribution has much more information on font naming (*note
Introduction: (fontname)Introduction.).
File: kpathsea.info, Node: Fallback font, Prev: Fontmap, Up: Glyph lookup
Fallback font
-------------
If a bitmap font cannot be found or created at the requested size,
Kpathsea looks for the font at a set of "fallback resolutions". You
specify these resolutions as a colon-separated list (like search paths).
Kpathsea looks first for a program-specific environment variable (e.g.,
`DVIPSSIZES' for Dvipsk), then the environment variable `TEXSIZES',
then a default specified at compilation time (the Make variable
`default_texsizes'). You can set this list to be empty if you prefer
to find fonts at their stated size or not at all.
Finally, if the font cannot be found even at the fallback resolutions,
Kpathsea looks for a fallback font, typically `cmr10'. Programs must
enable this feature by assigning to the global variable
`kpse_fallback_font' or calling `kpse_init_prog' (*note Calling
sequence::.); the default is no fallback font.

Suppressing warnings
====================
Kpathsea provides a way to suppress selected usually-harmless
warnings; this is useful at large sites where most users are not
administrators, and thus the warnings are merely a source of confusion,
not a help. To do this, you set the environment variable or
configuration file value `TEX_HUSH' to a colon-separated list of
values. Here are the possibilities:
`all'
Suppress everything possible.
`checksum'
Suppress mismatched font checksum warnings.
`lostchar'
Suppress warnings when a character is missing from a font that a
DVI or VF file tries to typeset.
`readable'
Suppress warnings about attempts to access a file whose permissions
render it unreadable.
`special'
Suppresses warnings about an unimplemented or unparsable
`\special' command.
`tex-hush.c' defines the function that checks the variable value. Each
driver implements its own checks where appropriate.

Programming overview
====================
Aside from this manual, your best source of information is the source
to the programs I've modified to use Kpathsea (*note Introduction::.).
Of those, Dviljk is probably the simplest, and hence a good place to
start. Xdvik adds VF support and the complication of X resources.
Dvipsk adds the complication of its own config files. Web2c is source
code I also maintain, so it uses Kpathsea rather straightforwardly, but
is of course complicated by the Web to C translation. Finally,
Kpsewhich is a small utility program whose sole purpose is to exercise
the main path-searching functionality.
Beyond these examples, the `.h' files in the Kpathsea source describe
the interfaces and functionality (and of course the `.c' files define
the actual routines, which are the ultimate documentation).
`pathsearch.h' declares the basic searching routine. `tex-file.h' and
`tex-glyph.h' define the interfaces for looking up particular kinds of
files. You may wish to use `#include <kpathsea/kpathsea.h>', which
includes every Kpathsea header.
The library provides no way for an external program to register new
file types: `tex-file.[ch]' must be modified to do this. For example,
Kpathsea has support for looking up Dvips config files, even though no
program other than Dvips will likely ever want to do so. I felt this
was acceptable, since along with new file types should also come new
defaults in `texmf.cnf' (and its descendant `paths.h'), since it's
simplest for users if they can modify one configuration file for all
kinds of paths.
Kpathsea does not parse any formats itself; it barely opens any files.
Its primary purpose is to return filenames. The GNU font utilities does
contain libraries to read TFM, GF, and PK files, as do the programs
above, of course.
File: kpathsea.info, Node: Calling sequence, Next: Program-specific files, Prev: Programming overview, Up: Programming
Calling sequence
================
The typical way to use Kpathsea in your program goes something like
this:
1. Call `kpse_set_program_name' with `argv[0]' as the first argument;
the second argument is a string or `NULL'. The second argument is
used by Kpathsea as the program name for the `.PROGRAM' feature of
config files (*note Config files::.). If the second argument is
`NULL', the value of the first argument is used. This function
must be called before any other use of the Kpathsea library.
If necessary, `kpse_set_program_name' sets the global variables
`program_invocation_name' and `program_invocation_short_name'.
These variables are used in the error message macros defined in
`kpathsea/lib.h'. It sets the global variable `kpse_program_name'
to the program name it uses. It also initializes debugging
options based on the environment variable `KPATHSEA_DEBUG' (if
that is set). Finally, it sets the variables `SELFAUTOLOC',
`SELFAUTODIR' and `SELFAUTOPARENT' to the location, parent and
grandparent directory of the executable, removing `.' and `..'
path elements and resolving symbolic links. These are used in the
default configuration file to allow people to invoke TeX from
anywhere, specifically from a mounted CD-ROM. (You can use
`--expand-var=\$SELFAUTOLOC', etc., to see the values finds.)
2. The `kpse_set_progname' is deprecated. A call to
`kpse_set_progname' with `argv[0]' is equivalent to a call of
`kpse_set_program_name' with first argument `argv[0]' and second
argument `NULL'. The function is deprecated because it cannot
ensure that the `.PROGRAM' feature of config files will always
work (*note Config files::.).
3. Set debugging options. *Note Debugging::. If your program doesn't
have a debugging option already, you can define one and set
`kpathsea_debug' to the number that the user supplies (as in Dviljk
and Web2c), or you can just omit this altogether (people can
always set `KPATHSEA_DEBUG'). If you do have runtime debugging
already, you need to merge Kpathsea's options with yours (as in
Dvipsk and Xdvik).
4. If your program has its own configuration files that can define
search paths, you should assign those paths to the `client_path'
member in the appropriate element of the `kpse_format_info' array.
(This array is indexed by file type; see `tex-file.h'.) See
`resident.c' in Dvipsk for an example.
5. Call `kpse_init_prog' (see `proginit.c'). It's useful for the DVI
drivers, at least, but for other programs it may be simpler to
extract the parts of it that actually apply. This does not
initialize any paths, it just looks for (and sets) certain
environment variables and other random information. (A search
path is always initialized at the first call to find a file of
that type; this eliminates much useless work, e.g., initializing
the BibTeX search paths in a DVI driver.)
6. The routine to actually find a file of type FORMAT is
`kpse_find_FORMAT', defined in `tex-file.h'. These are macros that
expand to a call to `kpse_find_file'. You can call, say,
`kpse_find_tfm' after doing only the first of the initialization
steps above--Kpathsea automatically reads the `texmf.cnf' generic
config files, looks for environment variables, and does expansions
at the first lookup.
7. To find PK and/or GF bitmap fonts, the routines are `kpse_find_pk',
`kpse_find_gf' and `kpse_find_glyph', defined in `tex-glyph.h'.
These return a structure in addition to the resultant filename,
because fonts can be found in so many ways. See the documentation
in the source.
8. To actually open a file, not just return a filename, call
`kpse_open_file'. This function takes the name to look up and a
Kpathsea file format as arguments, and returns the usual `FILE *'.
It always assumes the file must exist, and thus will search the
disk if necessary (unless the search path specified `!!', etc.).
In other words, if you are looking up a VF or some other file that
need not exist, don't use this.
Kpathsea also provides many utility routines. Some are generic: hash
tables, memory allocation, string concatenation and copying, string
lists, reading input lines of arbitrary length, etc. Others are
filename-related: default path, tilde, and variable expansion, `stat'
calls, etc. (Perhaps someday I'll move the former to a separate
library.)
The `c-*.h' header files can also help your program adapt to many
different systems. You will almost certainly want to use Autoconf for
configuring your software if you use Kpathsea; I strongly recommend
using Autoconf regardless. It is available from
`ftp://prep.ai.mit.edu/pub/gnu/'.
File: kpathsea.info, Node: Program-specific files, Next: Programming with config files, Prev: Calling sequence, Up: Programming
Program-specific files
======================
Many programs will need to find some configuration files. Kpathsea
contains some support to make it easy to place them in their own
directories. The Standard TeX directory structure (*note Introduction:
(tds)Top.), specifies that such files should go into a subdirectory
named after the program, like `texmf/ttf2pk'.
Two special formats, `kpse_program_text_format' and
`kpse_program_binary_format' exist, which use `.:$TEXMF/PROGRAM//' as
their compiled-in search path. To override this default, you can use
the variable `PROGRAMINPUTS' in the environment and/or `texmf.cnf'.
That is to say, the name of the variable is constructed by converting
the name of the program to upper case, and appending `INPUTS'.
The only difference between these two formats is whether
`kpse_open_file' will open the files it finds in text or binary mode.
File: kpathsea.info, Node: Programming with config files, Prev: Program-specific files, Up: Programming
Programming with config files
=============================
You can (and probably should) use the same `texmf.cnf' configuration
file that Kpathsea uses for your program. This helps installers by
keeping all configuration in one place.
To retrieve a value VAR from config files, the best way is to call
`kpse_var_value' on the string `VAR'. This will look first for an
environment variable VAR, then a config file value. The result will be
the value found or `NULL'. This function is declared in
`kpathsea/variable.h'. For an example, see the `shell_escape' code in
`web2c/lib/texmfmp.c'.
The routine to do variable expansion in the context of a search path
(as opposed to simply retrieving a value) is `kpse_var_expand', also
declared in `kpathsea/variable.h'. It's generally only necessary to
set the search path structure components as explained in the previous
section, rather than using this yourself.
If for some reason you want to retrieve a value *only* from a config
file, not automatically looking for a corresponding environment
variable, call `kpse_cnf_get' (declared in `kpathsea/cnf.h') with the
string VAR.
No initialization calls are needed.
