(formerly PCCTS) is a language tool that provides a framework for constructing recognizers, compilers, and translators from grammatical descriptions containing Java, C#, C++, or Python actions. ANTLR provides excellent support for tree construction, tree walking, and translation.

In this installment we look at two useful tools in the arsenal of any Linux programmer: lex and yacc. These tools have enabled us to easily build the scripting language and GUI framework that we used in Pirates Ho!, our SDL-based Linux game.

The VCG tool reads a textual and readable specification of a graph and visualizes the graph. If not all positions of nodes are fixed, the tool layouts the graph using several heuristics as reducing the number of crossings, minimizing the size of edges, centering of nodes. The specification language of the VCG tool is nearly compatible to GRL, the language of the edge tool, but contains many extensions. The VCG tool allows folding of dynamically or statically specified regions of the graph. It uses colors and runs on X11 and MS Windows 3.1. (An older version runs on Sunview).
The VCG tool is not a graph editor. It is intended to visualize large graphs that are automatically generated by programs, e.g. debuggers of data structures.

Lexical analysers (lexers) and parser generators, programming language creation kits
If you are thinking of creating your own programming language, writing a compiler or interpreter, or a scripting facility for your application, or even creating a documentation parsing facility, the tools on this page are designed to (hopefully) ease your task. These compiler construction kits, parser generators, lexical analyzer / analyser (lexers) generators, code optimzers (optimizer generators), provide the facility where you define your language and allow the compiler creation tools to generate the source code for your software.

JFlex is a lexical analyzer generator (also known as scanner generator) for Java(tm), written in Java(tm). It is also a rewrite of the very useful tool JLex which was developed by Elliot Berk at Princeton University. As Vern Paxson states for his C/C++ tool flex: They do not share any code though.
JFlex is designed to work together with the LALR parser generator CUP by Scott Hudson, and the Java modification of Berkeley Yacc BYacc/J by Bob Jamison. It can also be used together with other parser generators like ANTLR or as a standalone tool.



PEG.js generates parser from a grammar that describes expected input and can specify what the parser returns (using semantic actions on matched parts of the input). Generated parser itself is a JavaScript object with a simple API.

John Maeda created the DBN language as a tool to teach programming to non-developers. It was quite an influential language; in fact it was the precursor of the popular processing language, developed by Maeda’s students Casey Reas and Ben Fry, taking many ideas from DBN.

Jison takes a context-free grammar as input and outputs a JavaScript file capable of parsing the language described by that grammar. You can then use the generated script to parse inputs and accept, reject, or perform actions based on the input. If you’re familiar with Bison or Yacc, or other clones, you’re almost ready to roll.
Jison can be installed for Node using npm
Once you have generated the parser and saved it, you no longer need Jison or any other dependencies.
The generated parser script may be included in a web page without any need for a CommonJS loading environment. It’s as simple as pointing to it via a script tag
The LALR(1) parser and lexical analyzer generator for JavaScript, written in JavaScript.
JS/CC is the first available parser development system for JavaScript and ECMAScript-derivates. It has been developed, both, with the intention of building a productive compiler development system and with the intention of creating an easy-to-use academic environment for people interested in how parse table generation is done general in bottom-up parsing.

Esprima (esprima.org) is an educational ECMAScript (also popularly known as JavaScript) parsing infrastructure for multipurpose analysis. It is also written in ECMAScript. Esprima is created and maintained by Ariya Hidayat.
