RE2 is a fast, safe, thread-friendly alternative to backtracking regular expression engines like those used in PCRE, Perl, and Python. It is a C++ library. This is the source code repository for RE2, a regular expression library. There is a fair amount of documentation (including code snippets) in the re2.h header file. Unless otherwise noted, the RE2 source files are distributed under the BSD-style license found in the LICENSE file. In POSIX mode, RE2 accepts standard POSIX (egrep) syntax...

GraphQL is a query language for your API, and a server-side runtime for executing queries by using a type system you define for your data. GraphQL isn't tied to any specific database or storage engine and is instead backed by your existing code and data. A GraphQL service is created by defining types and fields on those types, then providing functions for each field on each type. All packages generated from this repository come with embedded pdb and support Source Link. If you are having...

...Unlike any other such tool, re2c focuses on generating high efficient code for regular expression matching. As a result this allows a much broader range of use than any traditional lexer.

A C++ high-performance regex library and Flex-compatible lexical analyzer generator with full Unicode support, new indentation anchors, lazy quantifiers, and many other modern features. Accepts Flex lexer specification syntax and is compatible with Bison/Yacc parsers. Generates reusable source code that is easy to understand. Supports fast scanning of UTF-8/16/32 files, strings, and streams. The reflex scanner generator generates clean C++ lexer class code that is thread-safe. Generates Graphviz files to visualize state machine DFAs. ...

An LALR(1) and LALR(*) parser generator. Generates parsers up to 140 times the speed of ANTLR parsers, and 1/10th of the size or smaller. Contains the DFA lexer generator, 80% faster than flex lexers. Works with Visual Studio C++. Contains 27 grammars. Parsers build a symbol table. Parsers construct an abstract-syntax tree (AST). Parser are very fast and small. Reads ANTLR and YACC grammars, after making some changes. Accepts advanced EBNF grammar notation. Includes 4 sample projects. ...

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. ...

Enhances Notepad++ text editor's handling of GEDCOM files. View GEDCOM files with syntax highlighting of: level, xref id, tag, pointer, value and escape tokens. Customize coloration and font styles. Grammar errors are also highlighted. View GEDCOM files in outline mode by folding sections based on line level.

Simple lexical analyzer for ANSI C (C-88-090) language.

Simple header-only library written in C++, for lexical analysis of files in PDF format

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.

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.

A run-time configurable character stream tokenizer that allows the user to define token classes via regular expressions. The developer is not limited to predefined notions of whitespace, commenting, or word modalities.

YooParse stands for Yet-another Object-Oriented Parser code generator. It is the complement of YooLex, a lexer code generator. The purpose of YooParse is to generate a parser that integrates tightly with the scanner generated by YooLex.

...I am working on this project mainly to gather experience with the current C++ standart (C++ 11) and with compiler development, it is not (yet) intended for practical usage. This project is at an early stage of development. Currently implemented is a Lexer, Parser and Code Generator for compiling Python code into CPython-compatible bytecode.

This is (going to be) a simple interpreter of a simple weakly typed language. The code, now, contains only the token class along with some subclasses, a lexer and some other titbits.
