Parser Generators

Parsing module is a pure-Python module that implements an LR(1) parser generator, as well as CFSM and GLR parser drivers. From an algorithmic perspective, this is one of the most advanced parser generators in existence, for the following reasons: - The Parsing module uses a scalable algorithm... Platforms: *nix

This program is a parser that abstract a data structure from a given Entrez Gene record, and users of the parser can decide what to do/extract from the data structure. Perl Entrez Gene Parser project provides Perl parsers for NCBI's Entrez Gene based on regular expression, Parse::RecDescent,... Platforms: Windows, Mac, *nix, Perl, BSD Solaris

LLnextgen is an Extended-LL(1) parser generator. LLnextgen project is a rewrite of the LLgen parser generator by D. Grune and C.J.H. Jacobs which is part of the Amsterdam Compiler Kit (ACK). Like all parser generators, LLnextgen takes the description of the grammar with associated actions as... Platforms: *nix

LLg is a recursive descent parser generator. SYNOPSIS use LLg; @tokens = ( ADDOP => [-+], LEFTP => [(], RIGHTP => [)], INTEGER => 0|[1-9][0-9]*, ); $reader = Lex->new(@tokens); $ADDOP->debug; $expr = And->new(($factor, Any->new($ADDOP, $factor)), sub { shift(@_); my $result =... Platforms: *nix

KxParser is a dinamic and reliable parser library. There are many parser generators today on the market and you may be wondering why yet another? Answer is simple - because none of those parsers are dynamic initialized! What does it mean? Today's parsers allows you to define inputs and rules and... Platforms: Windows

SimpleParse provides a simple and fast parser generator using a modified version of the mxTextTools text-tagging engine. SimpleParse allows you to generate parsers directly from your EBNF grammar. Unlike most parser generators, SimpleParse generates single-pass parsers (there is no distinct... Platforms: BSD Solaris

Kelbt project can generate backtracking LALR parsers. Standard LALR parser generators emit an error upon encountering a conflict in the parse tables. Kelbt forges onward, generating parsers which handle conflicts by backtracking at runtime. Kelbt is able to generate a parser for any context-free... Platforms: *nix

Python is a nice scripting language. It even gives you access to it's own parser and compiler. It also gives you access to different other parsers for special purposes like XML and string templates. But sometimes you may want to have your own parser. This is what's pyPEG for. To get a quick... Platforms: Mac

VisualLangLab is a visual parser-generator IDE for development of parsers without code or script of any kind. It is simple in use, and easy to learn. Unlike other parser-generators, VisualLangLab represents parser rules as visual grammar-trees with distinct icons for the grammar-tree nodes. The... Platforms: *nix

yagg::Tutorial is a Perl module that contains a tutorial for yagg. SYNOPSIS # To use the generator ./yagg -m nonterminals.yg terminals.lg ./output/progs/generate 5 This tutorial will show you how to use yagg, by way of two examples. In the first example, we create a simple logical... Platforms: *nix

JFlex is a lexical analyzer generator (also known as scanner generator) for Java(tm), written in Java(tm). JFlex is designed to work together with the LALR parser generator CUP. It can also be used together with other parser generators like ANTLR or as a standalone tool. Features: - Faster... Platforms: Windows, *nix, Java, BSD Solaris

Dragon is a powerful parser generator. It produces a consequent, object-oriented, integrated scanner and parser solution. Dragon parser generator also scales for very large grammar defintions. Since dragon parses LR(1) grammars, the generation algorithm is quite CPU intensive. Using LR(1)... Platforms: *nix

RDFStore::Parser::SiRPAC is a Perl module that implements a streaming RDF Parser as a direct implementation of XML::Parser::Expat. SYNOPSIS use RDFStore::Parser::SiRPAC; use RDFStore::NodeFactory; my $p=new RDFStore::Parser::SiRPAC( ErrorContext => 2, Handlers => { Init => sub { print... Platforms: *nix

Makefile::Parser is a Simple Parser for Makefiles. SYNOPSIS use Makefile::Parser; $parser = Makefile::Parser->new; # Equivalent to ->parse(Makefile); $parser->parse or die Makefile::Parser->error; # Get last value assigned to the specified variable CC: print $parser->var(CC); # Get...
