A Ruby Port of Neil Fraser's diff_match_patch Library

RDiffMatchPatch¶ ↑

This is a Ruby port of Google’s DiffMatchPatch library (originally written by Neil Fraser neil.fraser.name) code.google.com/p/google-diff-match-patch/

Installation from GitHub Gems¶ ↑

sudo gem install arunthampi-rdiff_match_patch --source=http://gems.github.com

Installation from Source (More reliable)¶ ↑

git clone git://github.com/arunthampi/rdiff_match_patch.git
cd rdiff_match_patch
rake install

Status¶ ↑

As of now, only the ‘match’ capabilities of DiffMatchPatch have been implemented. Contributions are welcome to add support for Diff and Patch as well. Matching has been added as a module such as RDiffMatchPatch::Match.

The plan is that if you want only a specific functionality to be mixed in (to the String class for example), then you only include that particular module.

For example:

class String
  include RDiffMatchPatch::Match
end

When the entire library has been ported, you can get all the functionality by simply including the various RDiffMatchPatch modules, once they are implemented.

class String
  include RDiffMatchPatch::Match
  include RDiffMatchPatch::Patch
end

Usage¶ ↑

The module can be included like so:

class String
  include RDiffMatchPatch::Match
end

"abc".fuzzy_match("abc") # => 0
