env! but it outputs tokens instead of a string literal
A fuzzer generating arbitrary monomorphized ASTs and comparing the execution between ACIR and Brillig
SPL (Safe Policy Lisp) evaluator for Agent-Safe capability tokens. 150 lines, zero deps core, microseconds.
The "Simple Logic & Arithmetic Compiler" transforms a single expression into an abstract syntax tree.
A highly parallel Perl 5 interpreter written in Rust
AXON — the formal cognitive language: a deterministic, proof-carrying AI runtime. Native Rust lexer/parser/type-checker/IR generator (re-exported from axon-frontend) plus the runtime: typed channels (π-calculus mobility, capability extrusion), algebraic effects via Free Monad CPS handlers, lease kernel + reconcile loop, the Epistemic Security Kernel, Trust Types, Proof-Carrying Code (independently verifiable proof objects), and the closed-catalog extension mechanism. Crate publishes as `axon-lang`; library import is `use axon::*` so existing call sites keep working unchanged.
Rust implementation of nixfmt with exact Haskell compatibility
An MCP server providing structural code search via ast-grep
Typed AST generator for tree-sitter
Codegen crate for `auto_lsp`.
Dialect-aware SQL emission from sqlparser-rs AST types
