This repository contains multiple projects (each installable as separate gems).

• mustermann: Your personal string matching expert. This is probably what you're looking for.
• mustermann-contrib: A meta gem depending on all other official mustermann gems.
• mustermann-fileutils: Efficient file system operations using Mustermann patterns.
• mustermann-strscan: A version of Ruby's StringScanner made for pattern objects.
• mustermann-visualizer: Syntax highlighting and tree visualization for patterns.'
• A selection of pattern types for mustermann, each as their own little library, see below.

You can easily use the latest edge version from GitHub of any of these gems via Bundler:

github 'sinatra/mustermann' do
  gem 'mustermann'
  gem 'mustermann-contrib'
end

The identity, regexp and sinatra types are included in the mustermann gem, all the other types have their own gems.

Any software using Mustermann is obviously compatible with at least one of the above.

Ruby 2.6+ compatible Ruby implementation.

JRuby support is unknown, see more in issue #72.
