Tish — VS Code / Cursor extension

Syntax highlighting, snippets, tish-lsp (downloaded automatically), and build tasks for the Tish language.

Features

Feature	Details
Languages	`.tish`, `.tishx` (JSX-oriented grammar)
Snippets	`fn`, `afn`, `for`, `try`, `import`, …
LSP	First launch downloads `tish-lsp` from Tish GitHub Releases (cached). Optional PATH / custom path.
Tasks	Example tasks: run file, native compile (see below)
Problem matchers	`tish-compile`, `tish-rustc` for compile output

End users

Language server — No manual install. On first use, the extension downloads the binary for your OS (see docs/lsp-release-assets.md for asset names).
tish on PATH — Only if you use Run/Compile tasks.
Air-gapped / custom builds: set tish.languageServerPath or tish.languageServerDownload.url, or turn off download and use tish-lsp on PATH.

`spawn tish-lsp ENOENT` / LSP won’t start

That means the editor tried to run tish-lsp but it isn’t available. Common causes:

Download disabled — In Settings, enable Tish › Language Server Download: Enable (tish.languageServerDownload.enable), then Reload Window. The extension will fetch the binary once and cache it.
GUI apps don’t see your shell PATH — Even if tish-lsp works in Terminal, Cursor/VS Code may not. Set tish.languageServerPath to the full path of the binary, or rely on automatic download.
Unsupported OS/arch for bundled download — Set tish.languageServerPath or tish.languageServerDownload.url to a matching binary.

HTTP 404 when downloading `tish-lsp-*`

The extension pulls binaries from GitHub Releases (tish.languageServerDownload.repo + tag). A 404 means that release URL has no file with that name—often the compiler repo is private, the tag doesn’t exist yet, or CI hasn’t uploaded the assets (see docs/lsp-release-assets.md).

Workaround: From your Tish compiler checkout, build the LSP binary (package name may be tish_lsp or tish-lsp in that repo), e.g. cargo build -p tish_lsp --release or cargo build --bin tish-lsp --release, then in Cursor/VS Code set:

tish.languageServerPath → absolute path to the binary (e.g. …/tish/target/release/tish-lsp).

Optionally turn off tish.languageServerDownload.enable so it doesn’t retry the broken URL each time.

Extension maintainers (this repo)

Bump tishLsp.releaseTag in package.json when you want users to pull a newer tish-lsp from the Tish repo’s releases.
The Tish repo must publish matching binaries on that tag (see docs/lsp-release-assets.md).

Configuration

Setting	Description
`tish.languageServerPath`	Path to `tish-lsp` (overrides everything)
`tish.languageServerDownload.enable`	Use GitHub download (default on)
`tish.languageServerDownload.repo` / `releaseTag` / `url`	Override download source
`tish.trace.server`	LSP trace
`tish.format.enable`	Format on save

Tasks (workspace)

Add to .vscode/tasks.json:

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "tish: run current file",
      "type": "shell",
      "command": "tish",
      "args": ["run", "${file}"],
      "group": "test",
      "problemMatcher": []
    },
    {
      "label": "tish: compile (native)",
      "type": "shell",
      "command": "tish",
      "args": ["compile", "${file}", "--output", "${workspaceFolder}/tish_out", "--target", "native"],
      "group": "build",
      "problemMatcher": ["$tish-rustc"]
    }
  ]
}

Development

npm install
npm run compile

Press F5 for Extension Development Host. For LSP during dev, either allow download or set tish.languageServerPath in settings.

CI / publishing

Same pattern as tish: CI workflow plus separate release workflows per registry.

Workflow	Trigger	Purpose
`vscode-ci.yml`	push/PR to main, workflow_dispatch	Build VSIX, release_check (conventional commits), create prerelease with tish.vsix. Mirrors build-npm-binaries.yml.
`vscode-release.yml`	release published/edited	When prerelease promoted to full: download VSIX from release, publish to Visual Studio Marketplace. Mirrors npm-release.yml.
`open-vsx-release.yml`	release published/edited	Same trigger: download VSIX, publish to Open VSX (VSCodium, etc.).

VSCE_PAT — Visual Studio Marketplace (vscode-release).
VSX_TOKEN — Open VSX (create token; sign publisher agreement first).
Conventional commits — feat/fix/perf/BREAKING CHANGE required for main merge.
Align tishLsp.releaseTag with Tish’s GitHub release that ships tish-lsp binaries.
