DFA regular expression library & friends

Sample Amazon Lex chat bot web interface

A high-performance C++ regex library and lexical analyzer generator with Unicode support. Extends Flex++ with Unicode support, indent/dedent anchors, lazy quantifiers, functions for lex and syntax error reporting and more. Seamlessly integrates with Bison and other parsers.

Rust grammar tool libraries and binaries

Lex machinary for go.

c compiler based on flex(lex), bison(yacc) and LLVM, supports LLVM IR and obj code generation. 基于flex，bison以及LLVM，使用c++11实现的类C语法编译器, 支持生成中间代码及可执行文件.

LexRank algorithm for text summarization

snapdragon is an extremely pluggable, powerful and easy-to-use parser-renderer factory.

Lexer and parser generators for F#

A mini, simple and modular compiler lab for SYsU/SysY(tiny C). Based on Clang/LLVM/ANTLR4/Bison/Flex.

c语言编译器，用 lex 和 yacc 工具完成词法分析与语法分析并生成语法树，C++实现了语 法树的解析并生成中间代码，生成中间代码的过程中实现了错误检测。C++实 现了中间代码的优化操作。之后利用 python 对中间代码进行处理并生成 mips 汇编码并且可以成功在 PCSpim（mips 模拟器）上运行。
