Open Source C++ Parser Generators - Page 2

Wisent is an LALR(1) parser generator with pluggable front- and backends. It generates object-oriented code with clean namespace separation. A yacc-like frontend is currently accompanied by a C++ and a Java backend. The tool itself is implemented in C++.

Library providing real-life XBNF grammars. All ressources about XBNF neurotranslator compiler here : https://neurotranslator.sourceforge.io

XMLpg - XML parser generator. Generates an XML parser in C++ from a DTD. The generated code will provide validation as well as conversion of the input XML.

This project is a parser generator, like the lex and yacc, but is based on the JavaCC grammar. It was writing in c++, run on linux and dos, and don't use another library. The grammar parser is specified through a simple file, and the parser generated

The Chilon Library is a C++0x utility library. The most advanced parts are a command-line argument parser and a parser generator library based on parsing expression grammars with built in AST generation abilities.

cojson is a C++ pull-type JSON parser/serializer for constrained platforms, such as bare metal applications on low-end MCUs. It does not use memory allocation and has almost no external dependencies. It is not intrusive – it neither forces nor implies any particular design of the application. Instead it adapts to fit any existing application code. It is tolerant to data type mismatching. When such occurs, parser just skips mismatching data and makes best efforts to continue parsing. The parser is recursive, e.g. nested JSON elements are handled with the recursion. However, this recursion is driven by the structure definition, not by the input data, which prevents stack faults on malformed input data. cojson is character type neutral – it can work with signed or unsigned character, as well as with standard wide character types: wchar_t, char16_t and char32_t. It is also transparent for UTF8 and properly handles BOM sequence.

Implementation of a combined scanner and parser generator for object oriented C++ or Java code generation

A program for generating C++ code based on an RDF schema. The generated code can then navigate RDF structures that conform to the schema.

Native C++ implementation of a JSON library. Contains a Parser, a Generator and and easy-to-use Navigator in one single class. To build you will need at least a C++11 capable compiler such as MSVC 10 (express edition). There is no other 3rd party library required to compile or run it.

C++ parser generator based on project lemon

LR(k) parser generator (k>=0) implementation.

A file parser/generator interface

QPG is a lexer and parser generator tailored for modern C++. The syntax of its grammer is designed to be more flexible and easily read than those of traditional tools like flex and bison. It's build on Qt4 but can produce output independent of it.

qtBisonC++ is a general-purpose parser generator that converts a grammar description for an LALR(1) context-free grammar into a QT C++ program to parse that grammar. qtBisonC++ reads the given input files for a description of a scanner to generate. The description is in the form of grammar in Backus-Naur Form (BNF), called rules. qtBisonC++ generates as output a C++ source and include file, `lexyy.cpp` and `lexyy.h`, which defines a class `lexyy'. This file is compiled with your code to produce an executable. When the executable is run, it analyses its input to verify that its correspond to the grammar.

The SoulNG project contains two tools: a lexical analyzer generator slg and a parser generator spg. The generators and the produced lexical analyzers and parsers use four C++ libraries that are also included in the project. The slg tool takes a .lexer file that contains the description of a lexical analyzer as input and produces C++ source code for a lexical analyzer as output. The produced lexical analyzer is a finite state machine that recognizes patterns described as regular expressions and return corresponding token identifiers to the parser. The spg tool takes .parser files that contain descriptions of parsers as input and produces C++ source code for parser classes as output. The parser generator produces a recursive descent top-down backtracking parser that use the lexical analyzer generated by slg to tokenize the input.
