    Parser for Rust source code

    Parser for Rust source code

    Parser for Rust source code

    Parser for Rust source code is a major Rust crate for parsing Rust source code (token streams) into a syntax tree (AST) that procedural macros can inspect or transform. The primary target is macro authors: you can parse TokenStreams into syn::File, syn::Item, syn::Expr, syn::Type, etc. It offers rich data structures, fine-grained parsing, span tracking (for error reporting), traversal and mutation APIs (visit, fold, visit_mut), printing back to tokens, and strong feature-gating so you only compile what you need. ...

    LOL HTML

    LOL HTML

    Low output latency streaming HTML parser/rewriter with CSS API

    ...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.

    parcel/css

    A CSS parser, transformer, and minifier written in Rust

    A CSS parser, transformer, and minifier written in Rust. Parsing and minifying large files are completed in milliseconds, often with significantly smaller output than other tools. Many other CSS parsers treat property values as an untyped series of tokens. This means that each transformer that wants to do something with these values must interpret them itself, leading to duplicate work and inconsistencies.

    markdown-rs

    markdown-rs

    CommonMark compliant markdown parser in Rust with ASTs and extensions

    markdown-rs is an open-source markdown parser written in Rust. It’s implemented as a state machine (#![no_std] + alloc) that emits concrete tokens, so that every byte is accounted for, with positional info. The API then exposes this information as an AST, which is easier to work with, or it compiles directly to HTML. While most markdown parsers work towards compliancy with CommonMark (or GFM), this project goes further by following how the reference parsers (cmark, cmark-gfm) work, which is confirmed with thousands of extra tests. ...

    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.
