NAME

App::lcpan - Manage your local CPAN mirror

VERSION

This document describes version 1.072 of App::lcpan (from Perl distribution App-lcpan), released on 2023-03-28.

SYNOPSIS

See lcpan script.

FUNCTIONS

authors

Usage:

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

List authors.

Examples:

List all authors:
```
authors();
```

Find CPAN IDs which start with something:

authors(query => ["MICHAEL%"]); # -> ["MICHAEL", "MICHAELW", undef, {}]

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

added_or_updated_since => date

Include only records that are added/updated since a certain date.
added_or_updated_since_last_index_update => true

Include only records that are added/updated since the last index update.
added_or_updated_since_last_n_index_updates => posint

Include only records that are added/updated since the last N index updates.
cpan => dirname

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

Defaults to ~/cpan.
detail => bool

(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.
or => bool

When there are more than one query, perform OR instead of AND logic.
query => array[str]

Search query.
query_type => str (default: "any")

(No description)
random => true

Random sort.
result_limit => uint

Only return a certain number of records.
result_start => posint (default: 1)

Only return starting from the n'th record.
sort => array[str] (default: ["id"])

Sort the result.
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)

By default will return an array of CPAN ID's. If you set detail to true, will return array of records.

deps

Usage:

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

List dependencies of distributions.

Examples:

List what modules Module-List requires:
```
deps(dists => ["Module-List"]);
```
List modules Module-List requires (module name will be converted to distro name):
```
deps(dists => ["Module::List"]);
```
List what distribution that contains Sah::Schema::filename requires:
```
deps(modules => ["Sah::Schema::filename"]);
```
Sah::Schema::filename is included in Sah-Schemas-Path distribution, so this command is equivalent to "lcpan deps Sah-Schemas-Path". You can't do "lcpan deps Sah::Schema::filename" because lcpan will assume that you ask "lcpan deps Sah-Schema-filename" and there is no Sah-Schema-filename distribution.

List non-core modules Module-List requires:

deps(dists => ["Module-List"], include_core => 0);

List dependencies of a specific distribution release:
```
deps(dists => ["Module-List\@0.004"]);
```

By default only runtime requires are displayed. To see prereqs for other phases (e.g. configure, or build, or ALL) or for other relationships (e.g. recommends, or ALL), use the --phase and --rel options.

Note that dependencies information are taken from META.json or META.yml files. Not all releases (especially older ones) contain them. lcpan (like MetaCPAN) does not extract information from Makefile.PL or Build.PL because that requires running (untrusted) code.

Also, some releases specify dynamic config, so there might actually be more dependencies.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

added_or_updated_since => date

Include only records that are added/updated since a certain date.
added_or_updated_since_last_index_update => true

Include only records that are added/updated since the last index update.
added_or_updated_since_last_n_index_updates => posint

Include only records that are added/updated since the last N index updates.
added_since => date

Include only records that are added since a certain date.
added_since_last_index_update => true

Include only records that are added since the last index update.
added_since_last_n_index_updates => posint

Include only records that are added since the last N index updates.
cpan => dirname

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

Defaults to ~/cpan.
dists => array[perl::distname_with_optional_ver]

Distribution names (with optional version suffix, e.g. Foo-Bar@1.23).
dont_uniquify => bool

Allow showing multiple modules for different dists.
exclude_deps => array[perl::modname]

Exclude some dependencies from being shown.
flatten => bool

Instead of showing tree-like information, flatten it.

When recursing, the default is to show the final result in a tree-like table, i.e. indented according to levels, e.g.:
```
% lcpan deps -R MyModule
| module            | author  | version |
|-------------------|---------|---------|
| Foo               | AUTHOR1 | 0.01    |
|   Bar             | AUTHOR2 | 0.23    |
|   Baz             | AUTHOR3 | 1.15    |
| Qux               | AUTHOR2 | 0       |
```
To be brief, if Qux happens to also depends on Bar, it will not be shown in the result. Thus we don't know the actual Bar version that is needed by the dependency tree of MyModule. For example, if Qux happens to depends on Bar version 0.45 then MyModule indirectly requires Bar 0.45.

To list all the direct and indirect dependencies on a single flat list, with versions already resolved to the largest version required, use the flatten option:
```
% lcpan deps -R --flatten MyModule
| module            | author  | version |
|-------------------|---------|---------|
| Foo               | AUTHOR1 | 0.01    |
| Bar               | AUTHOR2 | 0.45    |
| Baz               | AUTHOR3 | 1.15    |
| Qux               | AUTHOR2 | 0       |
```
Note that Bar's required version is already 0.45 in the above example.
include_core => bool (default: 1)

The status field is the processing status of the file/release by lcpan. ok means file has been extracted and the meta files parsed, nofile means file is not found in mirror (possibly because the mirroring process excludes the file e.g. due to file size too large), nometa means file does not contain META.{yml,json}, unsupported means file archive format is not supported (e.g. rar), err means some other error in processing file.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

added_or_updated_since => date

Include only records that are added/updated since a certain date.
added_or_updated_since_last_index_update => true

Include only records that are added/updated since the last index update.

Defaults to ~/cpan.
detail => bool

(No description)

(No description)
has_makefilepl => bool

(No description)
has_metajson => bool

(No description)
has_metayml => bool

(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.
latest => bool

(No description)
no_path => bool

(No description)
or => bool

When there are more than one query, perform OR instead of AND logic.
query => array[str]

Search query.

Only return starting from the n'th record.
sort => array[str] (default: ["name"])

(No description)
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.
updated_since => date

Include only records that are updated since certain date.
updated_since_last_index_update => true

Include only records that are updated since the last index update.
updated_since_last_n_index_updates => posint

Include only records that are updated since the last N index updates.
use_bootstrap => bool (default: 1)

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

Returns an enveloped result (an array).

Return value: (any)

reset

Usage:

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

Reset (empty) the database index.

All data tables will be emptied. This includes all records in the log table as well as index_creation_time record in the meta table, so there is no records of previous indexing activity. There is also no record of resetting in the log.

Tables are not dropped and re-created. The meta table is not emptied.

This function is not exported.

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

Defaults to ~/cpan.
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.

HISTORY

This application began as CPAN::SQLite::CPANMeta, an extension of CPAN::SQLite. CPAN::SQLite parses 02packages.details.txt.gz and 01mailrc.txt.gz and puts the parse result into a SQLite database. CPAN::SQLite::CPANMeta parses the META.json/META.yml files in individual release files and adds it to the SQLite database.

In order to simplify things for the users (one-step indexing) and get more freedom in database schema, lcpan skips using CPAN::SQLite and creates its own SQLite database. It also parses 02packages.details.txt.gz but does not parse distribution names from it but instead uses META.json and META.yml files extracted from the release files. If no META.* files exist, then it will use the module name.

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.
