App::lcpan - Manage your local CPAN mirror
This document describes version 1.074 of App::lcpan (from Perl distribution App-lcpan), released on 2023-09-26.
See lcpan script.
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.
~/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.
index_name
index.db
cpan
./index.db
/home/ujang/lcpan.db
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")
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 ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.
Return value: (any)
By default will return an array of CPAN ID's. If you set detail to true, will return array of records.
detail
deps(%args) -> [$status_code, $reason, $payload, \%result_meta]
List dependencies of distributions.
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.
lcpan
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.
--phase
--rel
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.
META.json
META.yml
Makefile.PL
Build.PL
Also, some releases specify dynamic config, so there might actually be more dependencies.
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.
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.
Qux
Bar
MyModule
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:
flatten
% 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)
Include core modules.
include_indexed => bool (default: 1)
Include modules that are indexed (listed in 02packages.details.txt.gz).
include_noncore => bool (default: 1)
Include non-core modules.
include_unindexed => bool (default: 1)
Include modules that are not indexed (not listed in 02packages.details.txt.gz).
level => int (default: 1)
Recurse for a number of levels (-1 means unlimited).
modules => array[perl::modname]
perl_version => str (default: "v5.38.0")
Set base Perl version for determining core modules.
phase => str (default: "runtime")
rel => str (default: "requires")
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

This function is not exported.
modules(%args) -> [$status_code, $reason, $payload, \%result_meta]
List modules/packages.
dist => perl::distname
Filter by distribution.
namespaces => array[perl::modname]
Select modules belonging to certain namespace(s).

List reverse dependencies.
List what distributions depend on Sah::Schema::filename:
rdeps(modules => ["Sah::Schema::filename"]);
List what distributions depend on one of the modules in Sah-Schemas-Path:
rdeps(dists => ["Sah-Schemas-Path"]);
authors => array[str]
Filter certain author.
This can be used to select certain author(s).
authors_arent => array[str]
Filter out certain author.
This can be used to filter out certain author(s). For example if you want to know whether a module is being used by another CPAN author instead of just herself.
dists => array[perl::distname]

releases(%args) -> [$status_code, $reason, $payload, \%result_meta]
List releases/tarballs.
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.

nofile
nometa

full_path => bool
no_path => bool
sort => array[str] (default: ["name"])
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.

App::lcpan::Manual
CPAN::SQLite
CPAN::Mini
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.
02packages.details.txt.gz
01mailrc.txt.gz
CPAN::SQLite::CPANMeta
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.

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.
