man Getopt::Complete::Compgen (3): standard tab-completion callbacks

VERSION

This document describes Getopt::Complete::Compgen 0.26.

SYNOPSIS

# A completion spec can use any of the following, specified by a single
# word, or a single character, automatically:

use Getopt::Complete(
'myfile' => 'files', # or 'f'
'mydir' => 'directories', # or 'd'
'mycommand' => 'commands', # or 'c'
'myuser' => 'users', # or 'u'
'mygroup' => 'groups', # or 'd'
'myenv' => 'environment', # or 'e'
'myservice' => 'services', # or 's'
'myalias' => 'aliases', # or 'a'
'mybuiltin' => 'builtins' # or 'b'
);

DESCRIPTION

This module contains subroutines which can be used as callbacks with Getopt::Complete, and which implement all of the standard completions supported by the bash ``compgen'' builtin.

Running ``compgen -o files abc'' will produce the completion list as though the user typed ``abc<TAB>'', with the presumption the user is attempting to complete file names.

This module provides a subroutine names ``files'', with an alias named ``f'', which returns the same list.

The subroutine is suitable for use in a callback in a Getopt::Complete competion specification.

It does the equivalent for directories, executable commands, users, groups, environment variables, services, aliases and shell builtins.

These are the same:

 @matches = Getopt::Complete::Compgen::files("whatevercommand","abc","whateverparam",$whatever_other_args);
 
 @same = `bash -c "compgen -f sometext"`;
 chomp @same;

These are equivalent in any spec:

   \&Getopt::Complete::Compgen::files
   \&Getopt;:Complete::Compgen::f
  'Getopt::Complete::Compgen::files'
  'Getopt;:Complete::Compgen::f'
  'files'
  'f'
