ANother Tool for Language Recognition (ANTLR) is the name of a parser generator that uses LL(k) parsing. ANTLR is the successor to the Purdue Compiler Construction Tool Set (PCCTS), first developed in ... [More] 1989, and is under active development. Its maintainer is professor Terence Parr of the University of San Francisco. [Less]

Java Compiler Compiler is the most popular parser generator for use with Java applications. A parser generator is a tool that reads a grammar specification and converts it to a Java program that can ... [More] recognize matches to the grammar. In addition to the parser generator itself, JavaCC provides other standard capabilities related to parser generation such as tree building (via a tool called JJTree included with JavaCC), actions, debugging, etc. [Less]

Parsec is designed from scratch as an industrial-strength parser library. It is simple, safe, well documented (on the package homepage), has extensive libraries and good error messages, and is also fast.

Spirit is an object-oriented, recursive descent parser generator framework implemented using template meta-programming techniques. Expression templates allow Spirit to approximate the syntax of ... [More] Extended Backus Normal Form (EBNF) completely in C++. The Spirit framework enables a target grammar to be written exclusively in C++. EBNF grammar specifications can mix freely with other C++ code and, thanks to the generative power of C++ templates, are immediately executable. [Less]

Happy is a parser generator system for Haskell, similar to the tool `yacc' for C. Like `yacc', it takes a file containing an annotated BNF specification of a grammar and produces a Haskell module ... [More] containing a parser for the grammar. Happy is flexible: you can have several Happy parsers in the same program, and several entry points to a single grammar. Happy can work in conjunction with a lexical analyser supplied by the user (either hand-written or generated by another program), or it can parse a stream of characters directly (but this isn't practical in most cases). [Less]

popt is a command line option parsing library. While it is similiar to getopt, it contains a number of enhancements, including: 1) popt is fully reentrant 2) popt can parse arbitrary argv[] style ... [More] arrays while getopt(3) makes this quite difficult 3) popt allows users to alias command line arguments 4) popt provides convience functions for parsing strings into argv[] style arrays [Less]

Smarty-like template parser written in C++.

Ragel compiles finite state machines from regular languages into executable C, C++, Objective-C, D, Java or Ruby code. Ragel state machines can not only recognize byte sequences as regular expression ... [More] machines do, but can also execute code at arbitrary points in the recognition of a regular language. Code embedding is done using inline operators that do not disrupt the regular language syntax. [Less]

FlatPack came out of the frustration of having to mix file parsing logic with business logic. FlatPack on SourceForge: a Java (1.4+) flat file parser that handles CSV, fixed length and custom ... [More] delimiters. The formats are configured in XML, it is fast and released under Apache license 2.0. Substrings in a fixed width parse can be daunting to deal with when trying to analyze what existing code is doing, and what about when you have no comments... We also provide delimited file parsing; works with any delimiter / qualifier, multiline records, delimiter or qualifier allowed in column value. [Less]

SableCC is an object-oriented framework that generates compilers (and interpreters) in the Java programming language.
