App::lcpan::Cmd::update - Create/update local CPAN mirror
This document describes version 1.074 of App::lcpan::Cmd::update (from Perl distribution App-lcpan), released on 2023-09-26.
Usage:
handle_cmd(%args) -> [$status_code, $reason, $payload, \%result_meta]
Create/update local CPAN mirror.
This subcommand first create/update the mirror files by downloading from a remote CPAN mirror, then update the index.
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.
~/cpan
exclude_author => array[str]
Exclude files from certain author(s).
force_update_index => bool
Update the index even though there is no change in files.
include_author => array[str]
Only include files from certain author(s).
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.
index_name
index.db
cpan
./index.db
/home/ujang/lcpan.db
max_file_size => int
If set, skip downloading files larger than this.
remote_url => str
Select CPAN mirror to download from.
retry_delay => int
Number of seconds to delay between retry attempt.
retry_max_attempts => int
Number of retry attempts on failed HTTP request.
skip_file_indexing_pass_1 => bool
(No description)
skip_file_indexing_pass_2 => bool
skip_file_indexing_pass_3 => bool
skip_index_file_patterns => array[re]
Skip one or more file patterns from being indexed.
skip_index_files => array[str]
Skip one or more files from being indexed.
skip_sub_indexing => bool (default: 1)
Since sub indexing is still experimental, it is not enabled by default. To enable it, pass the --no-skip-sub-indexing option.
--no-skip-sub-indexing
skip_sub_indexing_file_patterns => array[re]
Skip one or more file patterns from being parsed for subs.
skip_sub_indexing_files => array[str]
Skip one or more files from being parsed for subs.
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.
update_files => bool (default: 1)
Update the files.
update_index => bool (default: 1)
Update the index.
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)

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.
