# ABSTRACT: No line insertion and does Package version with our
__END__
=pod
=head1 NAME
Dist::Zilla::Plugin::OurPkgVersion - No line insertion and does Package version with our
=head1 VERSION
version 0.21
=head1 SYNOPSIS
in dist.ini
[OurPkgVersion]
in your modules
# VERSION
=head1 DESCRIPTION
This module was created as an alternative to
L<Dist::Zilla::Plugin::PkgVersion> and uses some code from that module. This
module is designed to use a the more readable format C<our $VERSION =
$version;> as well as not change then number of lines of code in your files,
which will keep your repository more in sync with your CPAN release. It also
allows you slightly more freedom in how you specify your version.
=head2 EXAMPLES
in dist.ini
...
version = 0.01;
[OurPkgVersion]
in lib/My/Module.pm
package My::Module;
# VERSION
...
output lib/My/Module.pm
package My::Module;
our $VERSION = '0.01'; # VERSION
...
please note that whitespace before the comment is significant so
package My::Module;
BEGIN {
# VERSION
}
...
becomes
package My::Module;
BEGIN {
our $VERSION = '0.01'; # VERSION
}
...
while
package My::Module;
BEGIN {
# VERSION
}
...
becomes
package My::Module;
BEGIN {
our $VERSION = '0.01'; # VERSION
}
...
you can also add additional comments to your comment
...
# VERSION: generated by DZP::OurPkgVersion
...
becomes
...
our $VERSION = '0.1.0'; # VERSION: generated by DZP::OurPkgVersion
...
you can also use perltidy's default static side comments (##)
...
## VERSION
...
becomes
...
our $VERSION = '0.1.0'; ## VERSION
...
Also note, the package line is not in any way significant, it will insert the
C<our $VERSION> line anywhere in the file before C<# VERSION> as many times as
you've written C<# VERSION> regardless of whether or not inserting it there is
a good idea. OurPkgVersion will not insert a version unless you have C<#
VERSION> so it is a bit more work.
If you make a trial release, the comment will be altered to say so:
# VERSION
becomes
our $VERSION = '0.01'; # TRIAL VERSION

=head1 METHODS
=over
=item BUILD
Provides validations after object creation.
=item munge_files
Override the default provided by L<Dist::Zilla::Role::FileMunger> to limit
the number of files to search to only be modules and executables.
=item munge_file
tells which files to munge, see L<Dist::Zilla::Role::FileMunger>.
=item finder
Override the default L<FileFinder|Dist::Zilla::Role::FileFinder> for
finding files to check and update. The default value is C<:InstallModules>
and C<:PerlExecFiles> (when available; otherwise C<:ExecFiles>)
-- see also L<Dist::Zilla::Plugin::ExecDir>, to make sure the script
files are properly marked as executables for the installer.
=back
=head1 PROPERTIES
=over
=item underscore_eval_version
For version numbers that have an underscore in them, add this line
immediately after the our version assignment:
$VERSION = eval $VERSION;
This is arguably the correct thing to do, but changes the line numbering
of the generated Perl module or source, and thus optional.
=item semantic_version
Setting this property to "true" (1) will set the version of the
module/distribution to properly use semantic versioning. It will also expect
that you setup C<version> with a v-string, without adding quotes. For example:
version = v0.0.1
Beware you can't setup both C<underscore_eval_version> and C<semantic_version>
since both are mutually exclusive: if you try, your code is going to C<die>.
For more details, check
L<this blog|https://weblog.bulknews.net/how-to-correctly-use-semantic-version-vx-y-z-in-perl-modules-eb08568ab911>
for more details about using semantic version with Perl.
=item skip_main_module
Set to true to ignore the main module in the distribution. This prevents
a warning when using L<Dist::Zilla::Plugin::VersionFromMainModule> to
obtain the version number instead of the C<dist.ini> file.
=item overwrite
When enabled, this option causes any match of the C<< # VERSION >> comment
to first check for an existing C<< our $VERSION = ...; >> on the same line,
and if found, overwrite the value in the existing statement. (the comment
still gets modified for trial releases)
Currently, the value must be a single Perl token such as a string or number.
=item no_critic
When C<underscore_eval_version> is used the generated code for dev versions
may not technically be L<Perl::Critic> compliant due to string eval, but is
nevertheless pretty safe. This option will add the appropriate C<no critic>
directive to save you the hassle.
