Abstract base class for formatting option help. OptionParser
instances should use one of the HelpFormatter subclasses for
formatting help; by default IndentedHelpFormatter is used.
Instance attributes:
parser : OptionParser
the controlling OptionParser instance
indent_increment : int
the number of columns to indent per nesting level
max_help_position : int
the maximum starting column for option help text
help_position : int
the calculated starting column for option help text;
initially the same as the maximum
width : int
total number of columns for output (pass None to constructor for
this value to be taken from the $COLUMNS environment variable)
level : int
current indentation level
current_indent : int
current indentation level (in columns)
help_width : int
number of columns available for option help text (calculated)
default_tag : str
text to replace with each option's default value, "%default"
by default. Set to false value to disable default value expansion.
option_strings : { Option : str }
maps Option instances to the snippet of help text explaining
the syntax of that option, e.g. "-h, --help" or
"-fFILE, --file=FILE"
_short_opt_fmt : str
format string controlling how short options with values are
printed in help text. Must be either "%s%s" ("-fFILE") or
"%s %s" ("-f FILE"), because those are the two syntaxes that
Optik supports.
_long_opt_fmt : str
similar but for long options; must be either "%s %s" ("--file FILE")
or "%s=%s" ("--file=FILE").

Abstract base class.
Class attributes:
standard_option_list : [Option]
list of standard options that will be accepted by all instances
of this parser class (intended to be overridden by subclasses).
Instance attributes:
option_list : [Option]
the list of Option objects contained by this OptionContainer
_short_opt : { string : Option }
dictionary mapping short option strings, eg. "-f" or "-X",
to the Option instances that implement them. If an Option
has multiple short option strings, it will appears in this
dictionary multiple times. [1]
_long_opt : { string : Option }
dictionary mapping long option strings, eg. "--file" or
"--exclude", to the Option instances that implement them.
Again, a given Option can occur multiple times in this
dictionary. [1]
defaults : { string : any }
dictionary mapping option destination names to default
values for each destination [1]
[1] These mappings are common to (shared by) all components of the
controlling OptionParser, where they are initially created.

Class attributes:
standard_option_list : [Option]
list of standard options that will be accepted by all instances
of this parser class (intended to be overridden by subclasses).
Instance attributes:
usage : string
a usage string for your program. Before it is displayed
to the user, "%prog" will be expanded to the name of
your program (self.prog or os.path.basename(sys.argv[0])).
prog : string
the name of the current program (to override
os.path.basename(sys.argv[0])).
epilog : string
paragraph of help text to print after option help
option_groups : [OptionGroup]
list of option groups in this parser (option groups are
irrelevant for parsing the command-line, but very useful
for generating help)
allow_interspersed_args : bool = true
if true, positional arguments may be interspersed with options.
Assuming -a and -b each take a single argument, the command-line
-ablah foo bar -bboo baz
will be interpreted the same as
-ablah -bboo -- foo bar baz
If this flag were false, that command line would be interpreted as
-ablah -- foo bar -bboo baz
-- ie. we stop processing options as soon as we see the first
non-option argument. (This is the tradition followed by
Python's getopt module, Perl's Getopt::Std, and other argument-
parsing libraries, but it is generally annoying to users.)
process_default_values : bool = true
if true, option default values are processed similarly to option
values from the command line: that is, they are passed to the
type-checking function for the option's type (as long as the
default value is a string). (This really only matters if you
have defined custom types; see SF bug #955889.) Set it to false
to restore the behaviour of Optik 1.4.1 and earlier.
rargs : [string]
the argument list currently being parsed. Only set when
parse_args() is active, and continually trimmed down as
we consume arguments. Mainly there for the benefit of
callback options.
largs : [string]
the list of leftover arguments that we have skipped while
parsing options. If allow_interspersed_args is false, this
list is always empty.
values : Values
the set of option values currently being accumulated. Only
set when parse_args() is active. Also mainly for callbacks.
Because of the 'rargs', 'largs', and 'values' attributes,
OptionParser is not thread-safe. If, for some perverse reason, you
need to parse command-line arguments simultaneously in different
threads, use different OptionParser instances.

Declare that you are done with this OptionParser. This cleans up
reference cycles so the OptionParser (and all objects referenced by
it) can be garbage-collected promptly. After calling destroy(), the
OptionParser is unusable.

parse_args(args : [string] = sys.argv[1:],
values : Values = None)
-> (values : Values, args : [string])
Parse the command-line options found in 'args' (default:
sys.argv[1:]). Any errors result in a call to 'error()', which
by default prints the usage message to stderr and calls
sys.exit() with an error message. On success returns a pair
(values, args) where 'values' is an Values instance (with all
your option values) and 'args' is the list of arguments left
over after parsing options.

Check that the supplied option values and leftover arguments are

(possibly adjusted, possibly completely new -- whatever you
like). Default implementation just returns the passed-in
values; subclasses may override as desired.
