Doctrine Lexer
Base library for a lexer that can be used in Recursive Descent Parsers
...The Lexer is responsible for giving you an API to walk across a string one character at a time and analyze the type of each character, value and position of each token in the string. The low level API of the lexer is pretty simple. The setInput($input) option sets the input data to be tokenized. The Lexer is immediately reset and the new input tokenized. -

LOL HTML
Low output latency streaming HTML parser/rewriter with CSS API
...The crate serves as a back-end for the HTML rewriting functionality of Cloudflare Workers, but can be used as a standalone library with a convenient API for a wide variety of HTML rewriting/analysis tasks. The parser switches back to the tag scanner as soon as input leaves the scope of all selector matches. The tag scanner may also sometimes switch the parser to the Lexer - if it requires additional tag information for the parsing feedback simulation. Having two different parser implementations for the same grammar will increase development costs and is error-prone due to implementation inconsistencies. We minimize these risks by implementing a small Rust macro-based DSL which is similar in spirit to Ragel. -

Red Programming Language
Red is a next-generation programming language
Red is a next-generation programming language strongly inspired by Rebol, but with a broader field of usage thanks to its native-code compiler, from system programming to high-level scripting and cross-platform reactive GUI, while providing modern support for concurrency, all in a zero-install, zero-config, single 1MB file! During the work on the low-level parts of the new Red lexer, the need arised for intra-function factorization abilities to keep the lexer code as DRY as possible. Subroutines were introduced to solve that. They act as the GOSUB directive from Basic language. They are defined as a separate block of code inside a function's body and are called like regular functions (but without any arguments). ... -

Automa.jl
A julia code generator for regular expressions
Automa is a regex-to-Julia compiler. By compiling regex to Julia code in the form of Expr objects, Automa provides facilities to create efficient and robust regex-based lexers, tokenizers and parsers using Julia's metaprogramming capabilities. You can view Automa as a regex engine that can insert arbitrary Julia code into its input-matching process, which will be executed when certain parts of the regex match an input. -

ANTLR
Parser generator to read, process, or translate structured text
ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It's widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees. It’s widely used in academia and industry to build all sorts of languages, tools, and frameworks. Twitter search uses ANTLR for query parsing, with over 2 billion queries a day. The languages for... -

gojq
Pure Go implementation of jq
This is an implementation of jq command written in Go language. You can also embed gojq as a library to your Go products. gojq is purely implemented with Go language and is completely portable. jq depends on the C standard library so the availability of math functions depends on the library. jq also depends on the regular expression library and it makes building scripts complex. gojq implements nice error messages for invalid query and JSON input. The error message of jq is sometimes... -

GraphQL for .NET
This is an implementation of Facebook's GraphQL in .NET
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... -

soulng
Lexer and parser generator tool for C++
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. ... -
