NAME

App::lcpan::Cmd::doc - Show POD documentation of module/POD/script

VERSION

This document describes version 1.073 of App::lcpan::Cmd::doc (from Perl distribution App-lcpan), released on 2023-07-09.

FUNCTIONS

handle_cmd

Usage:

handle_cmd(%args) -> [$status_code, $reason, $payload, \%result_meta]

Show POD documentation of module/POD/script.

Examples:

  • Seach module/POD/script named Rinci:

    handle_cmd(name => "Rinci");

  • Specifically choose .pm file:

    handle_cmd(name => "Rinci.pm");

  • Specifically choose .pod file:

    handle_cmd(name => "Rinci.pod");

  • Look for script first named strict:

    handle_cmd(name => "strict", script => 1);

  • Dump the raw POD instead of rendering it:

    handle_cmd(name => "Text::Table::Tiny", format => "raw");

This command extracts module (.pm)/.pod/script from release tarballs and render its POD documentation. Since the documentation is retrieved from the release tarballs in the mirror, the module/.pod/script needs not be installed.

Note that currently this command has trouble finding documentation for core modules because those are contained in perl release tarballs instead of release tarballs of modules, and lcpan is currently not designed to work with those.

This function is not exported.

Arguments ('*' denotes required arguments):

  • cpan => dirname

    Location of your local CPAN mirror, e.g. /path/to/cpan.

    Defaults to ~/cpan.

  • format => str (default: "man")

    (No description)

  • index_name => filename (default: "index.db")

    Filename of index.

    If index_name is a filename without any path, e.g. index.db then index will be located in the top-level of cpan. If index_name contains a path, e.g. ./index.db or /home/ujang/lcpan.db then the index will be located solely using the index_name.

  • name* => str

    Module or script name.

    If the name matches both module name and script name, the module will be chosen. To choose the script, use --script (-s).

  • script => bool

    Look for script first.

  • update_db_schema => bool (default: 1)

    Whether to update database schema to the latest.

    By default, when the application starts and reads the index database, it updates the database schema to the latest if the database happens to be last updated by an older version of the application and has the old database schema (since database schema is updated from time to time, for example at 1.070 the database schema is at version 15).

    When you disable this option, the application will not update the database schema. This option is for testing only, because it will probably cause the application to run abnormally and then die with a SQL error when reading/writing to the database.

    Note that in certain modes e.g. doing tab completion, the application also will not update the database schema.

  • use_bootstrap => bool (default: 1)

    Whether to use bootstrap database from App-lcpan-Bootstrap.

    If you are indexing your private CPAN-like repository, you want to turn this off.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)

CONTRIBUTING

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.
