Releases

CLI for the Harn programming language — run, test, REPL, format, and lint

Opt-in code-intelligence and deterministic-tool host builtins for the Harn VM

Downloadable on-device prompt-injection classifier for Harn (Layer 2)

Debug Adapter Protocol implementation for Harn

Async bytecode virtual machine for the Harn programming language

Cross-file module graph and import resolution utilities for Harn

CFG and invariant analysis for the Harn programming language

Code formatter for the Harn programming language

Parser, AST, and type checker for the Harn programming language

#[harn_builtin] proc-macro: emits a runtime registration entry plus a parser BuiltinSignature from a single annotated function.

Runtime-installable builtin signature registry. Decouples harn-parser (consumer) from harn-vm (producer) without a dependency cycle.

Harn grammar for tree-sitter

Embedded Harn standard library source catalog

define_opcodes! proc-macro: emits the VM Op enum, sync/async dispatch, disassembly, and classification helpers from a single declarative table.

Embedded skill corpus for the Harn CLI and runtime

Tokenizer with span tracking for the Harn programming language

Glob pattern matching primitives for the Harn programming language

Trait surface for client extensions to the Heddle CLI. OSS default is a noop impl; closed builds replace it via [patch.crates-io].

Unified time + sleep abstraction for the Harn runtime, CLI, triggers, cron, and harn-cloud.

Shared type definitions for Harn builtin signatures (BuiltinSignature, Param, Ty). Consumed by both harn-parser and harn-vm so signatures stay cycle-free.

CLI-side utilities shared between Heddle's OSS cli crate and the closed heddle-client crate: user config, remote target resolution, client config.
