    tree-sitter

    tree-sitter

    An incremental parsing system for programming tools

    Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. General enough to parse any programming language. Fast enough to parse on every keystroke in a text editor. Robust enough to provide useful results even in the presence of syntax errors.

    JSDoc

    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.

    CCC

    CCC

    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.

    Ox: Attribute Grammar Compiling System

    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...

    JSON Parser

    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. ...

    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.
