ANTLR Version 2.7.5 January 28, 2005
ANTLR, ANother Tool for Language Recognition, (formerly PCCTS) is a language tool that provides a framework for constructing recognizers, compilers, and translators from grammatical descriptions containing Java, C++, or C# actions [You can use PCCTS 1.xx to generate C-based parsers].
Computer language translation has become a common task. While compilers and tools for traditional computer languages (such as C or Java) are still being built, their number is dwarfed by the thousands of mini-languages for which recognizers and translators are being developed. Programmers construct translators for database formats, graphical data files (e.g., PostScript, AutoCAD), text processing files (e.g., HTML, SGML). ANTLR is designed to handle all of your translation tasks.
Terence Parr has been working on ANTLR since 1989 and, together with his colleagues, has made a number of fundamental contributions to parsing theory and language tool construction, leading to the resurgence of LL(k)-based recognition tools.
Here is a chronological history and credit list for ANTLR/PCCTS.
If you are looking for the previous main version (PCCTS 1.33) of ANTLR rather than the new Java-based version, see Getting started with PCCTS.
