Joyride User Scripting

Joyride User Scripting

Reference files: This document links to references/*.cljs files. Resolve them relative to this file's path using read_file.

User scope scripts and source files live in ~/.config/joyride/ and are available globally across all VS Code windows.

If you haven't loaded the joyride skill yet, load it now — it covers core evaluation patterns, async handling, and API reference.

Activation Script

user_activate.cljs runs automatically when Joyride activates. Use it to set up persistent UI elements, event handlers, and other disposables.

The canonical pattern uses a !db atom to track disposables for clean reload:

(defonce !db (atom {:disposables []}))

(defn push-disposable! [disposable]
  (swap! !db update :disposables conj disposable)
  (.push (.-subscriptions (joyride/extension-context)) disposable))

(defn clear-disposables! []
  (run! (fn [d] (.dispose d)) (:disposables @!db))
  (swap! !db assoc :disposables []))

See references/user_activate.cljs for the full activation script with the Joy status bar button.

Script Execution Guard

Scripts run their main logic only when invoked as a script, not when loaded in the REPL:

(when (= (joyride/invoked-script) joyride/*file*)
  (main))

Without this guard, loading a script namespace in the REPL triggers its side effects.

Source Files and ^:export

Source files in src/ expose functions callable from keyboard shortcuts:

(ns my-utils
  (:require ["vscode" :as vscode]))

(defn ^:export my-command []
  (vscode/window.showInformationMessage "Hello!"))

Call from keybinding:

{
  "key": "ctrl+alt+j m",
  "command": "joyride.runCode",
  "args": "(require '[my-utils :as u] :reload) (u/my-command)"
}

See references/joy_button.cljs for a complete source file example with status bar items and QuickPick.

Keyboard Shortcuts

Add to VS Code's keybindings.json:

// Run a specific script
{
  "key": "ctrl+alt+j u",
  "command": "joyride.runUserScript",
  "args": "my-script.cljs"
}

// Execute inline code (calling a function from src/)
{
  "key": "ctrl+alt+j r",
  "command": "joyride.runCode",
  "args": "(require '[my-ns :as m] :reload) (m/my-function)"
}

Use :reload during development to pick up changes.

Managing Disposables

Register disposables with the extension context so they're cleaned up properly:

(let [disposable (vscode/workspace.onDidOpenTextDocument handler)]
  (.push (.-subscriptions (joyride/extension-context)) disposable))

For reloadable scripts (activation scripts, status bar items), use the clear-disposables! + push-disposable! pattern from the activation section above. This prevents event handlers from piling up on re-runs.

npm Dependencies

Install in the user Joyride directory:

cd ~/.config/joyride && npm install lodash

Then require in scripts:

(require '["lodash" :as _])

Clojure Dependencies — deps.edn

{:deps {org.clojure/clojurescript {:mvn/version "1.11.54"}
        funcool/promesa {:mvn/version "9.0.471"}}
 :paths ["src" "scripts"]}

This file configures the classpath for clojure-lsp analysis. The Promesa dependency is for clojure-lsp — at runtime, prefer ^:async/await.

clojure-lsp Configuration

To get clojure-lsp to analyze user Joyride code:

1. Add a :source-alias to <user-joyride-dir>/.lsp/config.edn:

   {:source-aliases #{:joyride-user}}
   

2. Add :joyride-user to your global/user deps.edn aliases:

   {:aliases
    {:joyride-user {:extra-deps {joyride/user {:local/root "<user-joyride-dir>"}}}}}
   

Version Control

Put the User Joyride directory under version control — treat it like dotfiles.

Getting Started Commands

• Joyride: Create User Activate Script — creates user_activate.cljs
• Joyride: Create Hello Joyride User Script — creates example script
• Joyride: Create User Source File... — creates a source file in src/
• Joyride: Run User Script — run a user script by name

Example: git-fuzzy

A sophisticated source file demonstrating extension API access (vscode.git), progressive QuickPick batch-loading, live diff preview via onDidChangeActive, and item-level action buttons.

See references/git_fuzzy.cljs for the complete implementation.

Install as a user source file (Joyride: Create User Source File... → git-fuzzy) and bind to a shortcut:

{
  "key": "ctrl+alt+j ctrl+alt+g",
  "command": "joyride.runCode",
  "args": "(require '[git-fuzzy :as gz] :reload) (gz/show-git-history!+)"
}

Example: keybinding-palette

A personal command palette for your keybindings. Reads keybindings.json (including comments via JSONC parsing), renders keys with Unicode symbols (⌘⌥⇧⌃), and executes the selected command — including commands with arguments. Add "title" fields to your keybindings for best experience.

Demonstrates: npm dependency (jsonc-parser), Node.js fs/path/os modules, platform-specific path construction, QuickPick with matchOnDescription and matchOnDetail, command execution with args.

See references/keybinding_palette.cljs for the complete implementation.

Installation

1. Install the npm dependency in the user Joyride directory:

   cd ~/.config/joyride && npm install jsonc-parser
   

2. Create the source file: Use Joyride: Create User Source File... → name it keybinding_palette, then paste the reference content. Or copy the file directly to ~/.config/joyride/src/keybinding_palette.cljs.

3. Add the keybinding to VS Code's keybindings.json:

   {
     "title": "Keybinding Command Palette",
     "key": "ctrl+alt+j ctrl+alt+j",
     "command": "joyride.runCode",
     "args": "(require '[keybinding-palette :as kp] :reload) (kp/show-palette!+)"
   }
   

4. Add "title" fields to other keybindings in keybindings.json — these become the searchable labels in the palette. Keybindings without titles are filtered out.

Platform note: The keybindings-path function currently constructs a macOS-specific path (~/Library/Application Support/...). For Linux or Windows, adapt the path construction to use the appropriate VS Code config directory.
