unparser ======== [](http://travis-ci.org/mbj/unparser) [](https://gemnasium.com/mbj/unparser) [](https://codeclimate.com/github/mbj/unparser) Generate equivalent source for ASTs from whitequarks awesome [parser](https://github.com/whitequark/parser). This library is in early development stage and still has some bugs/missing features. Nevertheless it is able to regenerate it own source and serves well for [mutant](https://github.cm/mbj/mutant) mutators and the in-memory vendoring for self hosting mutant. Usage ----- ```ruby require 'unparser' Unparser.unparse(your_ast) # => "the code" ``` Equivalent vs identical: ```ruby require 'unparser' code = <<-RUBY %w(foo bar) RUBY node = Parser::CurrentRuby.parse(code) generated = Unparser.unparse(node) # ["foo", "bar"], NOT %w(foo bar) ! code == generated # false, not identical code Parser::CurrentRuby.parse(generated) == node # true, but identical AST ``` Summary: unparser does not reproduce your source! It produces equivalent source. Installation ------------ Install the gem `unparser` via your prefered method. Credits ------- * [Markus Schirp (mbj)](https://github.com/mbj) Author Contributing ------------- * Fork the project. * Make your feature addition or bug fix. * Add tests for it. This is important so I don't break it in a future version unintentionally. * Commit, do not mess with Rakefile or version (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull) * Send me a pull request. Bonus points for topic branches. License ------- See LICENSE file.
