One platform to build, fine-tune, and deploy ML models. No MLOps team required.
Access Gemini 3 and 200+ models. Build chatbots, agents, or custom models with built-in monitoring and scaling.
KFlex is an extension to JFlex that makes it easy to generate lexers whose actions call methods of a listener interface. This simplifies parser development and makes the lexer a reusable drop-in component.
The LALR parser generator (LPG) is a tool for developing scanners and parsers written in Java, C++ or C. Input is specified by BNF rules. LPG supports backtracking (to resolve ambiguity), automatic AST generation and grammar inheritance.
Lapg is the combined lexical analyzer and parser generator, which converts a description for a context-free LALR grammar into source file to parse the grammar. Generates code for Java, Javascript, C, C++ and C#.
A simple way to create a syntax highlighting editor for a custom language/grammar and/or create custom grammar parsers. This is a .NET project written in C#. See details here: http://acct001.com/wordpress/?p=190

An other library for the common problem of parsing arbitrary text data.
A small, easy-to-use Java library
LR parser without lookahead limitation.
Semantic action defined in class not in grammar definition file.
Dresden OCLallows to query arbitrary EMF-based models. It provides an advanced OCL2 Editor, a Parser, an Interpreter, and a Codegenerator for Java and SQL.
WE MOVED TO GITHUB. PLEASE VISIT https://github.com/dresden-ocl/dresdenocl
A parser generator based on parsing expression grammar rules. It generates code and accepts actions in LLVM Assembly rather than C like its predecessor, PEG, did.
Verto is a compiler that uses a top-down recursive descent parser implemented in Java
for educational purposes. It translates Verto language (a subset of the C language) into Caesar machine language.
Verto is the Latin word for interpret.
Mixed Analog/Digital Simulator framework - parser and elaborator for Verilog and Verilog-AMS, and an extended C++ (ParC - http://parallel.cc) to be used as the simulation engine.
Generate a parser at runtime from a collection of C++ objects. Concisely state a parser specification in ordinary C++ code. Learn from a parser generator with an object-oriented design.
A Java library for parsing files and building Abstract Syntax Tree based on context free (CF) grammar.
Easy to use and provides fast prototyping. With grammar provided the library provides the AST of input. Command line interface is provided.
IvmaiAsn ASN1/ECN/XDR Tools. A collection of the ASN.1/ECN parser, XDR-to-ASN.1 converter and pretty-printer scripts for ASN.1/ECN specifications. Contains also a formal definition of the ASN.1 built-in types, ECN encoding classes and XDR encodings.
lightJacc is a small but strong grammar parser generator. It adopts a parsing strategy of its own: dynamic concurrent parsing -- which made it much stronger than LR or LL family CCs (YACC, ANTLR, etc), but still keep good performance.
ParGeL is an LALR(k) parser generator, which allows creation of inheritable parsers in runtime and compile time environments. ParGeL is written 100% in Java.
Complete LALR(1) parser generator and engine in PHP.
Complete LALR(1) parser generator and engine (like BISON or YACC) but it's all done in PHP, and the input grammar is easier and more maintainable. Write your actions in PHP. Generate PHP output code. Drive your parser with PHP. Wanna make a language?
OFD.NET is a project to create an Open Flash Debugger in C#, plus other tools targeting flash technology and especially actionScript. There are plans for a swf parser/generator, an AS3 compiler, a decompiler, etc.
This project aims at providing a parser for fortran source code. Output is in XML format. The parser is based on the g95 parser. Additionnal tools in Perl are provided: Fortran source browser; pseudo-compiler environment.
Annotation based lexer and parser generator suitable for processing wide range of languages, from small domain specific languages to big ones like Java. Actions may be written directly as annotated java methods. Examples of expression language and Java5.
CSP Canonical LR(1) Parser Generator. Includes lexer and parser generator. Supports all OS. Produces code as standard ANSI C++ w/ minimal STL and usable in commercial or non-commercial purposes.
More Than Parsing is a parser generator for context free grammars defined in a BNF-like format. It generates scanners, parsers, ASTs, etc. This sf project is no longer active, development will continue in a different place.
The fluffy language is a toy language designed around the libfirm intermediate representation library. It supports the typical low-level constructions known from C combined with generic programming constructs. Lexer and parser are extensible with plugins
QVT-Parser parses QVT-Relations model-transformation specifications from textual syntax into EMF QVT-models. QVT defines a language for expressing model-to-model transformations. The parser is is built using ANTLR and EMF.
