BQN VS Code plugin

This VS Code extension provides language support for BQN.

It is available on the Open VSX Registry and the VS Code Marketplace.

Setup

This extension has a focus on the CBQN implementation. The REPLXX=1 option must be enabled during building for best results.

Configurable Settings

You can add these settings to your settings.json file to disable some of the default behaviours of this extension.

• bqn.executablePath - Path to the CBQN executable e.g. /home/username/CBQN/BQN.
• bqn.saveBeforeLoadScript - Whether vscode should save the script before loading it into the CBQN REPL.
• bqn.sendToNewReplDelay - How long vscode should wait before sending text to a repl.
• bqn.executableSupportsReplxx - Marks whether the executable set in bqn.executablePath is built with replxx support.
• bqn.pendingBackslashBackgroundColor - Style customization feature for backslash completion.
• bqn.enableBackslashCompletion - true by default. If you have an extension that interferes with backslash completion (e.g. Vim keybindings), please set this to false and use a system-wide method.
• bqn.enableHoverDocumentation - Controls whether documentation will be displayed for a symbol on mouseover.

Features

Current

• Syntax highlighting.
• Backslash symbol completion (\r -> ↑) using the standard BQN keymap, like in the online REPL.
• Symbol completion by function name (take<tab> -> ↑).
• Help popups when hovering over glyphs.
• File, line, and selection execution in the integrated terminal (from @suhr and @mk12). This requires having a bqn executable in your PATH, or customizing the bqn.executablePath setting.

Planned

• Block context highlighting for symbols like 𝕨 and 𝕣.
• Inline code execution similar to nvim-bqn.
• CBQN WASM interpreter bundled with the extension.
• Add a symbol table to the sidebar for clickable BQN symbols.
