Free Compiler Construction Tools 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. If you want a (printed) book on compiler construction, you might want to check out the famous by Aho, Sethi and Ullman. The 'Dragon book', as it is affectionately called by some, is regarded by many as the standard book on writing compilers.

If you want for a particular language (eg, C, C++, Ada, COBOL, etc) to ease your task for constructing a compiler for that language, check out the page.

It has integrated support for Unicode character sets (UTF-8, UTF-16, UTF-32), generates thread-safe scanners by default, can optionally use Boost Regex as a regex engine, supports lazy quantifiers, word boundary anchors (etc) in regular expressions, and so on. When not invoked with flex compatibility, it will not use macros and globals. The generated scanner produces C++ scanner classes derived from a template. The source code is released under the BSD 3-Clause licence, and can be compiled under Windows, Mac OS X and Linux, although a Windows executable is also provided in the distribution package. Waxeye is a parser generator that takes a Parsing Expression Grammar (PEG) as input.

It supports C, Java, JavaScript, Python, Ruby and Scheme. It also supports modular grammars (where your grammar is split across multiple files) and grammar testing (to check that every component of your language is parsed the way you want it to). The program is released under the MIT licence. The peg program creates a C recursive descent parser generator from a Parsing Expression Grammar (PEG). The alternative, leg, uses a slightly different syntax to make it more convenient for those who are familiar with lex and yacc. Both support unlimited backtracking, ordered choice as a means for disambiguation, and can combine lexical analysis and parsing into a single activity. The program is released under the MIT licence, and the parsers created are unencumbered by any licence.

This program, re2c, generates C/C++ lexical analyzers. It takes regular expressions that you write and produces a deterministic finite automaton (DFA), which, when run, will process input according to your rules and execute the matching code (which you write).

Lex

Unlike lex and flex (see elsewhere on ), you do not call the yylex() function to start the lexer, but have access to a variety of lower-level functions which give you greater flexibility in processing your input. According to their website, this lexer generator is used in programs like and SpamAssassin. The source code is in the public domain. AdaGOOP, which stands for Ada Generator of Object Oriented Parsers, creates a parser that generate an object oriented parse tree, and a traversal of the tree using the visitor pattern.

It relies on the SCATC versions of aflex and ayacc which you can also get from their site. The source code is provided, and there are no restrictions on its use. Quex, or Queχ (depending on which part of the site you read), produces a directly coded lexical analyzer engine with pre- and post- conditions rather than the table-driven created by the Lex/Flex family (see elsewhere on ). Features include inheritable 'lexer modes' that provide transition control and indentation events, a general purpose token class, a token queue that allow tokens to be communicated without returning from the lexical analyzer function, line and column numbering, generation of transition graphs, etc. You will need to install before using this lexical analyser generator. It generates code. It is released under the GNU LGPL with additional restrictions; see the documentation for details., Mac OS X, Solaris and are supported.
