    UniCC LALR(1) Parser Generator

    UniCC LALR(1) Parser Generator

    Parser generator, targetting C, C++, Python, JavaScript, JSON and XML

    UniCC (UNIversal Compiler-Compiler) compiles an augmented grammar definition into a program source code that parses the described grammar. Because UniCC is intended to be target-language independent, it can be configured via template definition files to emit parsers in almost any programming language. UniCC comes with out of the box support for the programming languages C, C++, Python (both 2.x and 3.x) and JavaScript. Parsers can also be generated into JSON and XML.
