JSDoc
An API documentation generator for JavaScript
...JSDoc comments should generally be placed immediately before the code being documented. Each comment must start with a /** sequence in order to be recognized by the JSDoc parser. Adding a description is simple, just type the description you want in the documentation comment. Once your code is commented, you can use the JSDoc 3 tool to generate an HTML website from your source files. -

Claude Opus 4.6 wrote a dependency-free C compiler in Rust
Claude’s C Compiler is a remarkable experiment in automated software generation: a full C compiler written from scratch in Rust entirely by an AI model (Claude Opus 4.6) with minimal human intervention, capable of targeting multiple architectures like x86-64, i686, ARM, and RISC-V. The project implements every part of a traditional compiler — the lexer, parser, intermediate representation, optimizer, code generator, assembler, linker, and debug info emitter — without relying on any external toolchain, producing standalone executables in the ELF format. While still early and not fully validated for correctness, it demonstrates the frontier of what sophisticated AI can build in complex, systems-level software domains, including the potential to compile real operating systems and large software projects. -

Testing Files Generator
Test file generator for QA. Creates real PDF, PNG, ZIP, DOCX and more
Testing Files Generator is a tool for QA engineers and developers who need real files to test against - an upload form, a parser, anything that takes a file and has an opinion about it. You pick one of its 24 formats and the size you want, and you get exactly that: ask for a 10 MB PDF and you get a PDF that a reader will open, at 10 MB to the byte. GUI + CLI You are testing software that accepts files from people. -

Ox: Attribute Grammar Compiling System
Ox is an attribute-grammar evaluator generator.
Ox is an attribute grammar compiling system that augments Lex and Yacc specifications with definitions of synthesized and inherited attributes written in a combination of Ox and C/C++ syntax. From these augmented specifications, Ox generates ordinary Lex and Yacc specifications that build and decorate attributed parse trees. The user can specify parse-tree traversals for easy ordering of side effects such as code generation. Ox handles the tedious and error-prone details of writing code... -

Scrooge
A Thrift parser/generator
Scrooge is a thrift code generator written in Scala, which currently generates code for Scala, Java, Cocoa, Android, and Lua. It’s meant to be a replacement for the Apache thrift code generator and generates conforming, binary-compatible codecs by building on top of libthrift. Since Scala is API-compatible with Java, you can use the apache thrift code generator to generate Java files and use them from within Scala, but the generated code uses Java collections and mutable “bean” classes,... -

JSON Parser
JSON Parser written in C that outputs JSON into D-List list objects
JSON parser is a highly efficient JSON data decoder written in C, that parses JSON data into a form that is very easy to use from within C code. You only need to include the json-parser.h file in your source code. If your project does not already incorporate D-List, you will also need to include dlist.h The JSON parser package also includes a JSON validator that does not parse or create resources, but allows the caller to validate JSON data from unknown sources, prior to any parsing attempts. ... -

Instaparse
Instaparse aims to be the simplest way to build parsers in Clojure
Instaparse is a simple yet powerful parser generator for Clojure and ClojureScript that turns grammars written in EBNF or ABNF into executable parsers, with support for left recursion, ambiguous grammars, PEG-like lookahead, and various output formats. Instaparse supports most of the common notations for context-free grammars. For example, a popular alternative to * is to surround the term with curly braces {}, and a popular alternative to ? -

LR Parser and Lexer Generators: Fortran
LR parser generator and lexer generator for use in Fortran
...It generates Fortran declarations for character classes, recognized objects, named constants that represent the DFA. A third program generates declarations that connect the parser and lexer. The LR parser generator and lexer generator both use parsers and lexers generated by themselves. An infrastructure to use a generated lexer and parser is therefore included as part of these programs. -
