A RubyGems plugin that patches gems.
gem-patch is a RubyGems plugin that helps to patch gems without manually opening and rebuilding them. It opens a given
.gem file, extracts it, patches it with system
patch command, clones its spec, updates the file list and builds the patched gem.
gem install gem-patch and you are done.
On Fedora you can use YUM:
sudo yum install rubygem-gem-patch
gem patch [options] name-version.gem PATCH [PATCH ...]
|-pNUMBER||--strip-numberNUMBER||Sets the file name strip count to NUMBER.|
|-FNUMBER||--fuzz=NUMBER||Set NUMBER of lines to ignore in looking for places to install a hunk.|
|-oFILE||--output=FILE||Set output FILE.|
|--patch-options=OPTIONS||Pass additional patch command options.|
|-cPATHS||--copy-in=PATHS||Copy in files or folders (separated by comma)|
|-rPATHS||--remove=PATHS||Remove files or folders before rebuild (separated by comma)|
|--dry-run||Print the results from patching, but do not change any files.|
|--verbose||Print additional info and STDOUT from

--dry-run switch behaviour has been changed and it's not the same as in original
patch command. Instead,
patch command modify files, but doesn't override the gem to be patched nor the output file at the end. This way we can easily use dry run also for patches involving more diffs changing each other.
If you need to check patching files that are not part of .gem release (such as a separate test suite), you can do it with
--copy-in=test,folders option. If you don't want to include those additional files then delete them with
This version is build for both RubyGems 1.8 and RubyGems 2.0.
