Complete::Module - Complete with installed Perl module names


This document describes version 0.23 of Complete::Module (from Perl distribution Complete-Module), released on 2015-11-29.


 use Complete::Module qw(complete_module);
 my $res = complete_module(word => 'Text::A');
 # -> ['Text::ANSI', 'Text::ANSITable', 'Text::ANSITable::', 'Text::Abbrev']


$Complete::Module::OPT_SHORTCUT_PREFIXES => hash

Shortcut prefixes. The default is:

   df  => "DateTime/Format/",
   dz  => "Dist/Zilla/",
   dzb => "Dist/Zilla/PluginBundle/",
   dzp => "Dist/Zilla/Plugin/",
   dzr => "Dist/Zilla/Role/",
   pw  => "Pod/Weaver/",
   pwb => "Pod/Weaver/PluginBundle/",
   pwp => "Pod/Weaver/Plugin/",
   pwr => "Pod/Weaver/Role/",
   pws => "Pod/Weaver/Section/",

If user types one of the keys, it will be replaced with the matching value from this hash.



Can be used to set the default for $Complete::Module::OPT_SHORTCUT_PREFIXES. It should be in the form of:


For example:



complete_module(%args) -> any

Complete with installed Perl module names.

For each directory in @INC (coderefs are ignored), find Perl modules and module prefixes which have word as prefix. So for example, given Te as word, will return e.g. [Template, Template::, Term::, Test, Test::, Text::]. Given Text:: will return [Text::ASCIITable, Text::Abbrev, ...] and so on.

This function has a bit of overlapping functionality with Module::List, but this function is geared towards shell tab completion. Compared to Module::List, here are some differences: 1) list modules where prefix is incomplete; 2) interface slightly different; 3) (currently) doesn't do recursing; 4) contains conveniences for completion, e.g. map casing, expand intermediate paths (see Complete for more details on those features), autoselection of path separator character, some shortcuts, and so on.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • find_pm => bool (default: 1)

    Whether to find .pm files.

  • find_pmc => bool (default: 1)

    Whether to find .pmc files.

  • find_pod => bool (default: 1)

    Whether to find .pod files.

  • find_prefix => bool (default: 1)

    Whether to find module prefixes.

  • ns_prefix => str

    Namespace prefix.

    This is useful if you want to complete module under a specific namespace (instead of the root). For example, if you set ns_prefix to Dist::Zilla::Plugin (or Dist::Zilla::Plugin::) and word is F, you can get ['FakeRelease', 'FileFinder::', 'FinderCode'] (those are modules under the Dist::Zilla::Plugin:: namespace).

  • path_sep => str

    Path separator.

    For convenience in shell (bash) completion, instead of defaulting to :: all the time, will look at word. If word does not contain any :: then will default to /. This is because :: (contains colon) is rather problematic as it is by default a word-break character in bash and the word needs to be quoted to avoid word-breaking by bash.

  • word* => str (default: "")

    Word to complete.

Return value: (any)
