Install

Single-script install on Linux and macOS. Windows is in progress.

curl -fsSL https://raw.githubusercontent.com/airgap/parabun/main/install.sh | bash

The install script downloads a prebuilt binary (parabun) and the matching VS Code / Cursor / Kiro extension, drops them under ~/.parabun/, and adds the binary to your shell $PATH.

After installing, verify:

parabun --version
parabun -e 'console.log("hello")'

Editor extension

The VS Code-family extension (works for code, cursor, and kiro) provides:

• TextMate grammar for .pts / .ptsx / .pjs / .pjsx files.
• An LSP with hover, go-to-definition, semantic highlighting, purity diagnostics, memo arity hints, and operator documentation.
• Full chat-template detection on .gguf paths in bun:llm calls.

Install it independently of the runtime:

curl -fsSL https://raw.githubusercontent.com/airgap/parabun/main/install-extension.sh | bash

The script picks up whichever IDE binaries are on $PATH and installs the extension into all of them.

Updating

parabun self-update pulls the latest release and refreshes the editor extension at the same time. There is no semver-style channel split today; the install script tracks main.

Uninstall

rm -rf ~/.parabun
# remove the PATH export from your shell rc

The extension is uninstalled through the IDE's own extension manager.

Build from source

git clone https://github.com/airgap/parabun
cd parabun
bun install
bun bd                 # debug build at ./build/debug/bun-debug
bun run build:release  # release build at ./build/release/bun

bun bd accepts trailing arguments and passes them to the built binary, which is the recommended way to run your local build (bun bd test foo.test.ts, bun bd -e 'console.log("hi")'). See CLAUDE.md in the repo for the full build flag reference.
