App::RewriteVersion - A tool to rewrite and bump your Perl module versions


 use App::RewriteVersion;
 my $app = App::RewriteVersion->new;
 # Options
 # Bump versions for modules in current dist directory
 # Bump versions in specified dist directory
 $app->rewrite_versions($app->bump_version($app->current_version(dist_dir => $dist_dir)), dist_dir => $dist_dir);
 # Override module to read version from
 $app->rewrite_versions($app->bump_version($app->current_version(file => $file)));
 # Bump versions in specific subdirectories
 $app->rewrite_versions($app->bump_version($app->current_version), subdirs => ['foo','bar']);
 # Custom version bump algorithm
 $app->rewrite_versions($app->bump_version($app->current_version, sub { shift + 0.05 }));
 # Don't bump, just synchronize versions with main module
 # Set versions to specified version


App::RewriteVersion is a tool for managing Perl module versions in a distribution. It is heavily based on the Dist::Zilla plugin Dist::Zilla::Plugin::RewriteVersion. Similarly to that plugin, the V environment variable can be used to override the version detected from the main module.

Existing version assignments and new versions must be parseable with the same rules as in "DESCRIPTION" in Dist::Zilla::Plugin::RewriteVersion, that is to say, they should either be a decimal number with a single decimal point, or a tuple version with a leading v and at least 3 segments separated by decimal points. Version assignments should be in the form our $VERSION = '...';.

See perl-rewrite-version and perl-bump-version for details on command-line usage.



 my $bool = $app->allow_decimal_underscore;
 $app = $app->allow_decimal_underscore(0);

If true, decimal versions with underscores will be allowed. Defaults to true. See "Using underscore in decimal $VERSION" in Dist::Zilla::Plugin::BumpVersionAfterRelease for more information.


 my $bool = $app->dry_run;
 $app = $app->dry_run(1);

If true, the module will process files as normal but not actually modify them. Useful with "verbose" to verify expected functionality.

 my $bool = $app->follow_symlinks;
 $app = $app->follow_symlinks(1);

If true, the application will follow symlinked directories when traversing the distribution for modules. Defaults to false.


 my $bool = $app->global;
 $app = $app->global(1);

If true, the application will replace all version assignments found instead of just the first instance in each file. Defaults to false.


 my $bool = $app->verbose;
 $app = $app->verbose(1);

Enable progress messages to be printed to STDOUT. Defaults to false.



 my $app = App::RewriteVersion->new;

Construct a new App::RewriteVersion object.


 my $new_version = $app->bump_version($version);
 my $new_version = $app->bump_version($version, sub { $_[0] + 1 });

Increments a version string, returning the new version string. An optional coderef can be passed for custom version bump logic. The coderef will receive the current version string as the first argument and is expected to return a new version string. By default, Version::Next is used. An exception will be thrown if an invalid version is passed according to the current settings.


 my $current_version = $app->current_version;
 my $current_version = $app->current_version(dist_dir => $dist_dir);
 my $current_version = $app->current_version(file => $file);

Returns the current version of the distribution using "version_from". If no file is passed, the main module filename will be guessed from dist_dir (defaulting to current working directory), using heuristics similar to Dist::Zilla::Plugin::NameFromDirectory and "main_module" in Dist::Zilla. For example, if the directory is named Foo-Bar it will look for lib/Foo/ within the distribution, and if that doesn't exist, the shortest module path found. If the V environment variable is set, it will be returned regardless of other options. An exception will be thrown if no version is found in the specified or guessed file, or if no perl modules could be found.


 my $bool = $app->rewrite_version($file, $version);
 my $bool = $app->rewrite_version($file, $version, is_trial => $is_trial);

Rewrites the version of the file at $file to $version if it has a version assignment in the form our $VERSION = '...';. Returns true if the version was rewritten, or false if no version assignment was found. If is_trial is true, # TRIAL will be appended to the version assignment line when rewriting. The -TRIAL indication is not part of the version and should be added to the name of the archive you upload to PAUSE, which is outside of the scope of this tool. An exception will be thrown if an invalid version is passed, or an I/O error occurs. A warning will be printed if $version is lower than the version previously declared in the file.


 $app = $app->rewrite_versions($version);
 $app = $app->rewrite_versions($version, dist_dir => $dist_dir);
 $app = $app->rewrite_versions($version, is_trial => 1);
 $app = $app->rewrite_versions($version, subdirs => ['lib']);

Rewrites the versions of all perl files found in dist_dir (defaulting to current working directory) to $version using "rewrite_version". The subdirs option can be used to specify an arrayref of subdirectories relative to dist_dir in which versions will be rewritten, otherwise defaulting to lib, script, and bin. If passed, the is_trial option is passed through to "rewrite_version". An exception will be thrown if an invalid version is passed, or an I/O error occurs.


 my $version = $app->version_from($file);

Attempts to read version from the file at $file. Returns undef if no version assignment was found.
