A universal, multi-language, multi-paradigm code analyzer

Mulang is a tool for analysing source code, which is built on top of five main components:

  1. an Abstract Semantic Tree, an intermediate language which allows to express the semantic - as opposed to syntatic - structure of a multi-paradigm program;
  2. a set of more than 90 inspections for querying code querying code either explicitly - expectations - or implicitlt - smells.
  3. an Expectations Definition Language (EDL), a language for defining custom expectations
  4. a command line tool for analysing both source code in many languages and Mulang's AST. This tool is distributed as both a linux-amd64 binary and a JavaScript package. See downloads section.
  5. higher level interfaces in ruby and javascript that are easier to use and provides some additional capabilities like expectations parsing and automatic internationalized humanization.
