=head1 NAME
parse-cpan-changes - Parse CPAN Changes file
=head1 VERSION
This document describes version 0.077 of parse-cpan-changes (from Perl distribution App-CPANChangesUtils), released on 2022-06-13.
=head1 SYNOPSIS
% B<parse-cpan-changes> [B<--class>=I<perl::modname>] [B<--debug>|B<--log-level>=I<level>|B<--quiet>|B<--trace>|B<--verbose>] [B<--format>=I<name>|B<--json>] [B<--(no)naked-res>] [B<--page-result>[=I<program>]|B<--view-result>[=I<program>]] [B<--parse-release-metadata>|B<--no-parse-release-metadata>|B<--noparse-release-metadata>] [B<--unbless>|B<--no-unbless>|B<--nounbless>] -- [I<file>]
See examples in the L</EXAMPLES> section.
=head1 DESCRIPTION
This utility is a simple wrapper for L<CPAN::Changes>.
=head1 OPTIONS
C<*> marks required options.
=head2 Main options
=over
=item B<--class>=I<s>
Default value:
 "CPAN::Changes"
=item B<--file>=I<s>
If not specified, will look for file called Changes/ChangeLog in current directory.
Can also be specified as the 1st command-line argument.
=item B<--no-parse-release-metadata>
If set to true (the default), the utility will attempt to parse release metadata
in the release note. The release note is the text after the version and date in
the first line of a release entry:
 0.001 - 2022-06-10 THIS IS THE RELEASE NOTE AND CAN BE ANY TEXT
One convention I use is for the release note to be semicolon-separated of
metadata entries, where each metadata is in the form of HTTP-header-like "Name:
Value" text where Name is dash-separated words and Value is any text that does
not contain newline or semicolon. Example:
 0.001 - 2022-06-10  Urgency: high; Backward-Incompatible: yes
Note that Debian changelog also supports "key=value" in the release line.
This option, when enabled, will first check if the release note is indeed in the
form of semicolon-separated metadata. If yes, will create a key called
C<metadata> in the release result structure containing a hash of metadata:
 { "urgency" => "high", "backward-incompatible" => "yes" }
Note that the metadata names are converted to lowercase.
=item B<--no-unbless>
If you set this to false, you'll need to use an output format that can handle
serializing Perl objects, e.g. on the CLI using C<--format=perl>.
=back
=head2 Logging options
=over
=item B<--debug>
Shortcut for --log-level=debug.
=item B<--log-level>=I<s>
Set log level.
By default, these log levels are available (in order of increasing level of
importance, from least important to most): C<trace>, C<debug>, C<info>,
C<warn>/C<warning>, C<error>, C<fatal>. By default, the level is usually set to
C<warn>, which means that log statements with level C<info> and less important
levels will not be shown. To increase verbosity, choose C<info>, C<debug>, or
C<fatal>.
For more details on log level and logging, as well as how new logging levels can
be defined or existing ones modified, see L<Log::ger>.
=item B<--quiet>
Shortcut for --log-level=error.
=item B<--trace>
Shortcut for --log-level=trace.
=item B<--verbose>
Shortcut for --log-level=info.
=back
=head2 Output options
=over
=item B<--format>=I<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.
=item B<--json>
Set output format to json.
=item B<--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
C<--naked-res> so you just get:
 [1,2,3]
=item B<--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. C<less> is chosen.
=item B<--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.
=back
=head2 Other options
=over
=item B<--help>, B<-h>, B<-?>
Display help message and exit.
=item B<--version>, B<-v>
Display program's version and exit.
=back
=head1 COMPLETION
This script has shell tab completion capability with support for several
shells.
=head2 bash
To activate bash completion for this script, put:
 complete -C parse-cpan-changes parse-cpan-changes
in your bash startup (e.g. F<~/.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 L<cpanm-shcompgen>
which can activate shell completion for scripts immediately.
=head2 tcsh
To activate tcsh completion for this script, put:
 complete parse-cpan-changes 'p/*/`parse-cpan-changes`/'
in your tcsh startup (e.g. F<~/.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 L<shcompgen> (see above).
=head2 other shells
For fish and zsh, install L<shcompgen> as described above.

=head1 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 L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>, and sometimes one or two other
Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required
beyond that are considered a bug and can be reported to me.
