NAME
complete – file name completion |
SYNOPSIS
#include <u.h> #include <libc.h> #include <complete.h>
typedef struct CompletionCompletion;
Completion* complete(char *dir, char *s);
void freecompletion(Completion *c); |
DESCRIPTION
The complete function implements file name completion. Given a
directory dir and a string s, it returns an analysis of the file
names in that directory that begin with the string s. The fields
nmatch and nfile will be set to the number of files that match
the prefix and filename will be filled in with their names. If
the file named is a directory, a slash character will be appended
to it. If no files match the string, nmatch will be zero, but complete will return the full set of files in the directory, with nfile set to their number. The flag advance reports whether the string s can be extended without changing the set of files that match. If true, string will be set to the extension; that is, the value of string may be appended to s by the caller to extend the embryonic file name unambiguously. The flag complete reports whether the extended file name uniquely identifies a file. If true, string will be suffixed with a blank, or a slash and a blank, depending on whether the resulting file name identifies a plain file or a directory. The freecompletion function frees a Completion structure and its contents.
In rio(1) and acme(1), file name completion is triggered by a
control–F character or an Insert character. |

DIAGNOSTICS
The complete function returns a null pointer and sets errstr if
the directory is unreadable or there is some other error. |
BUGS
The behavior of file name completion should be controlled by the
plumber. |
