    jackson-core

    Core part of Jackson that defines Streaming API

    This project contains core low-level incremental ("streaming") parser and generator abstractions used by Jackson Data Processor. It also includes the default implementation of handler types (parser, generator) that handle JSON format. The core abstractions are not JSON specific, although naming does contain 'JSON' in many places, due to historical reasons. Only packages that specifically contain the word 'json' are JSON-specific.

    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.

    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.

    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.

    This framework implements a strict JSON parser and generator

    Chunk-based JSON parsing and generation in Objective-C. SBJson's number one feature is stream/chunk-based operation. Feed the parser one or more chunks of UTF8-encoded data and it will call a block you provide with each root-level document or array. Or, optionally, for each top-level entry in each root-level array. With this you can reduce the apparent latency for each download/parse cycle of documents over a slow connection. You can start parsing and return chunks of the parsed document...

    JSON implementation for Ruby

    JSON implementation for Ruby

    JSON implementation for Ruby

    This is an implementation of the JSON specification according to RFC 4627. You can think of it as a low-fat alternative to XML if you want to store data on disk or transmit it over a network rather than use a verbose markup language. Both variants of the JSON generator generate UTF-8 character sequences by default. If an:ascii_only option with a true value is given, they escape all non-ASCII and control characters with \uXXXX escape sequences, and support UTF-16 surrogate pairs in order to...

    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.

    Mocker++11

    C++ Mock object auto generator

    Unlike Java or other languages where reflection / introspection is available, mocking is not easy with C++. Even with Google Mock, we need some hand writing. I solved this problem by using home made class declaration parser/generator that reads the class declaration (header file), then generates a mock class. What you need is to run the generator and full featured mock class is there for your unit test. ---- How to use: You need Ruby. Obtain it if you don't have it yet.

    The Ilcg2 compiler compiler

    Ilcg2 extends the Intermediate Language for Code Generation, by combining it with the sablecc parser generator. The resulting tool allows complete compilers to be generated with only a relatively small translator class in Java being required to map abstract syntax trees to abstract semantic trees. The lexical analysis, parsing, and generation of vectorised assembler code are all automated.
