PERL-REVERSION(1p)					User Contributed Perl Documentation					PERL-REVERSION(1p)

NAME
perl-reversion - Manipulate project version numbers SYNOPSIS
perl-reversion [options] [file ...] Options: -help see this summary -man view man page for perl-reversion -bump make the smallest possible increment -bump-revision increment the specified version component -bump-version -bump-subversion -bump-alpha -set <version> set the project version number -current <version> specify the current version -normal print current version in a specific format OR -numify force versions to be a specific format, -stringify with -set or -bump -dryrun just go through the motions, but don't actually save files DESCRIPTION
A typical distribution of a Perl module has embedded version numbers is a number of places. Typically the version will be mentioned in the README file and in each module's source. For a module the version may appear twice: once in the code and once in the pod. This script makes it possible to update all of these version numbers with a simple command. To update the version numbers of specific files name them on the command line. Any directories will be recursively expanded. If used with no filename arguments perl-reversion will attempt to update README and any files below lib/ in the current project. OPTIONS
"-bump" Attempt to make the smallest possible increment to the version. The least significant part of the version string is incremented. 1 => 2 1.1 => 1.2 1.1.1 => 1.1.2 1.1.1_1 => 1.1.1_2 "-bump-revision" "-bump-version" "-bump-subversion" "-bump-alpha" Increment the specified version component. Like the "inc_*" methods of Perl::Version, incrementing a component sets all components to the right of it to zero. "-set <version>" Set the version to the specified value. Unless the "-normal" option is also specified the format of each individual version string will be preserved. "-current <version>" Specify the current version. Only matching version strings will be updated. "-normal" "-numify" "-stringify" Use a specific formatting, as in "Formatting" in Perl::Version. Alone, these options control how the current (found) version is displayed. With "-bump" or "-set", also update version strings to have the given formatting, regardless of the version format passed to "-set" or the current version (for "-bump"). If none of these options are specified, perl-reversion will preserve the formatting of each individual version string (the same as "-stringify"). "-dryrun" If set, perl-reversion will not save files. Use this to see what gets changed before it actually happens. AUTHOR
