Tish - Native Performance, Familiar Syntax

This page describes planned or partial tooling beyond the core LSP + VS Code extension.

Debugger (DAP)

Status: Not shipped.

Tish can run interpreted (VM) or as a native binary compiled to Rust. A solid debug story would require one of:

Interpreted debugging — Debug Adapter Protocol talking to the VM with breakpoints mapped to Tish source lines (feasible for tish run / VM backend).
Native debugging — Source-level mapping from generated Rust back to Tish (heavy; needs stable line tables or DWARF-style mapping).

Recommendation: Start with (1) for development workflows; document lldb/gdb on the generated binary for advanced native debugging until (2) exists.

Tree-sitter grammar

Status: Partial — an incremental grammar lives in the main repo as tree-sitter-tish (subset of the language; growing with LANGUAGE.md).

It enables:

ast-grep and other Tree-sitter-based tooling (see the sibling tish-security repository next to tish)
Future editor highlighters (Neovim / Helix / Zed) and WASM playground highlighting

TextMate grammars in tish-vscode cover VS Code/Cursor today.

Playground

A web playground (similar to play.rust-lang.org) https://tish.sh/

Other ideas

Idea	Notes
`js_to_tish` in editor	Convert selection via CLI or future code action.
Test explorer	LSP test API or extension integration.
Organize imports	LSP code action once module graph is richer.
