Complete::Module - Complete with installed Perl module names


This document describes version 0.263 of Complete::Module (from Perl distribution Complete-Module), released on 2023-03-19.


 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:

   bs  => "Bencher/Scenario/",
   bss => "Bencher/Scenarios/",
   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/",
   rp  => "Regexp/Pattern/",
   ss  => "Sah/Schema/",
   sss => "Sah/Schemas/",
If user types one of the keys, it will be replaced with the matching value from
this hash.




 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):

  • exclude_dir => bool

    (No description)

  • exclude_leaf => bool

    (No description)

  • 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 => perl::modname

    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).

  • ns_prefixes => array[perl::modname]

    Namespace prefixes.

    If you specify this instead of ns_prefix, then the routine will search from all the prefixes instead of just one.

  • 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.

  • recurse => bool

    (No description)

  • recurse_matching => str (default: "level-by-level")

    (No description)

  • word* => str (default: "")

    Word to complete.

Return value: (any)

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
