  • mustermann-contrib: A gem with additional pattern types and extensions.

Projects using Mustermann

Mustermann is typically used by other frameworks and libraries, primarily but not exclusively for handing HTTP requests.

These include, amongst others:

  • Sinatra:
    A DSL for quickly creating web applications with minimal effort
  • Hanami:
    A flexible framework for maintainable Ruby apps
  • Grape:
    An opinionated framework for creating REST-like APIs in Ruby.
  • Padrino:
    A Ruby web framework built upon Sinatra.
  • Praxis:
    A framework that focuses on both the design and implementation aspects of creating APIs.
  • Webspicy:
    A technology agnostic specification and test framework that yields better coverage for less testing effort.
  • Alchemrest:
    Betterment's library for building robust, reliable, performant integrations with third party APIs, with a focus on making APIs work with the rest of your domain layer not against it.
  • HTTP Fake:
    An HTTP fake implementation for test suites.
  • oas_parser and oas_parser_reborn:
    An open source Open API Spec 3 Definition Parser
  • Pendragon:
    Provides an HTTP router and its toolkit for use in Rack. As a Rack application, it makes it easy to define complicated routing.
  • Wayferer:
    Web crawling framework based on ActiveJob.
  • apiculture:
    A toolkit for building REST APIs on top of Rack. By WeTransfer.

Git versions with Bundler

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

Pattern Types

The identity, regexp, rails, and sinatra types are included in the mustermann gem, all the other types listed here are part of the mustermann-contrib gem. There are also third-party gems providing additional types, like mustermann-grape.

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

About the name

  • Erika Mustermann and Max Mustermann are official German placeholder names, like Jane Doe and John Doe in English. They are used on official documents, like identity cards, when the real name of a person is not known or must be withheld for privacy reasons. This seems very fitting for a library offering placeholders in strings.
  • Muster is German for "pattern", so Mustermann can be read as "pattern man" or "pattern person".
  • Referring to it as The Amazing Mustermann is a Spider-Man reference.

Requirements

Ruby 3.3+ compatible Ruby implementation (MRI, JRuby, and TruffleRuby are tested).
