VERSION

This document describes version 0.023 of list-new-cpan-dists (from Perl distribution App-ListNewCPANDists), released on 2023-03-28.

SYNOPSIS

list-new-cpan-dists --help (or -h, -?)

list-new-cpan-dists --version (or -v)

list-new-cpan-dists [--cpan=dirname] [--db-name=filename] [--debug|--log-level=level|--quiet|--trace|--verbose] [--exclude-author-re=re] [(--exclude-author=cpan::pause_id)+|--exclude-authors-json=json] [--exclude-dist-re=re] [(--exclude-dist=perl::distname)+|--exclude-dists-json=json] [--format=name|--json] [--include-author-re=re] [(--include-author=cpan::pause_id)+|--include-authors-json=json] [--include-dist-re=re] [--last-month] [--last-week] [--last-year] [--(no)naked-res] [--page-result[=program]|--view-result[=program]] [--this-month] [--this-week] [--this-year] [--today] [--yesterday] [--include-dists-json=json] -- [from_time] [to_time]

See examples in the "EXAMPLES" section.

DESCRIPTION

This utility queries MetaCPAN to find out what CPAN distributions are new in a given time period (i.e. has their first release made during that time period). This utility also collects the information in a SQLite database which defaults to ~/cpan/index-lncd.db or ~/index-lncd.db if ~/cpan~ does not exist. You can customize the location of the generated SQLite database using the cpan and db_name arguments.

OPTIONS

* marks required options.

Db options

--db-name=s

Filename of database.

Default value:

"index-lncd.db"

Filtering options

--exclude-author-re=s

--include-authors-json=s

See --include-author.

--include-dists-json=s

(No description)

Local cpan options

--cpan=s

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

Defaults to ~/cpan. This actually does not need to be a real CPAN local mirror, but can be just an empty directory. If you use happen to use App::lcpan, you can use the local CPAN mirror generated by lcpan (which also defaults to ~/cpan) to store the database.

Logging options

--debug

Shortcut for --log-level=debug.

--log-level=s

Set log level.

By default, these log levels are available (in order of increasing level of importance, from least important to most): trace, debug, info, warn/warning, error, fatal. By default, the level is usually set to warn, which means that log statements with level info and less important levels will not be shown. To increase verbosity, choose info, debug, or trace.

For more details on log level and logging, as well as how new logging levels can be defined or existing ones modified, see Log::ger.

--quiet

Shortcut for --log-level=error.

--trace

Shortcut for --log-level=trace.

--verbose

Shortcut for --log-level=info.

Output options

--format=s

Choose output format, e.g. json, text.

Default value:

undef

Output can be displayed in multiple formats, and a suitable default format is chosen depending on the application and/or whether output destination is interactive terminal (i.e. whether output is piped). This option specifically chooses an output format.

--json

Set output format to json.

--naked-res

When outputing as JSON, strip result envelope.

Default value:

0

By default, when outputing as JSON, the full enveloped result is returned, e.g.:

[200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use --naked-res so you just get:

[1,2,3]
--page-result

Filter output through a pager.

This option will pipe the output to a specified pager program. If pager program is not specified, a suitable default e.g. less is chosen.

--view-result

View output using a viewer.

This option will first save the output to a temporary file, then open a viewer program to view the temporary file. If a viewer program is not chosen, a suitable default, e.g. the browser, is chosen.

Time filtering options

--from-time=s, --from

(No description)

Can also be specified as the 1st command-line argument.

--last-month

(No description)

--last-week

Monday is the start of the week.

--last-year

(No description)

--this-month

(No description)

--this-week

Monday is the start of the week.

--this-year

(No description)

--to-time=s, --to

(No description)

Can also be specified as the 2nd command-line argument.

--today

(No description)

--yesterday

(No description)

Other options

--help, -h, -?

Display help message and exit.

--version, -v

Display program's version and exit.

COMPLETION

This script has shell tab completion capability with support for several shells.

bash

To activate bash completion for this script, put:

complete -C list-new-cpan-dists list-new-cpan-dists

in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.

tcsh

To activate tcsh completion for this script, put:

complete list-new-cpan-dists 'p/*/`list-new-cpan-dists`/'

in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.

It is also recommended to install shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.

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.
