# joyride-workspace-automation

Guides GitHub Copilot to build project-specific VS Code scripts with ClojureScript and Joyride. It enforces REPL-driven development directly inside the editor runtime.

## What it does

This rule configures GitHub Copilot for files matching `**/.joyride/**`. The assistant acts as a ClojureScript developer using Joyride inside VS Code's Extension Host. Rather than rewriting files directly, it tests small expressions step by step via `joyride_evaluate_code` in the active REPL. Source files are updated only when requested explicitly.

Code follows a data-oriented ClojureScript approach with argument maps, destructuring, and namespaced keywords such as `:project/type`. The rule discourages `println` or `js/console.log` in favor of evaluating nested sub-expressions in code blocks beginning with `(in-ns ...)`. Project startup logic is designed around `workspace_activate.cljs`.

Without Joyride and the `joyride_evaluate_code` tool active in VS Code, the model cannot validate API calls against the live runtime.

## Install

### GitHub Copilot (native platform)

**Manually: put the files in place**
- File: `.github/instructions/joyride-workspace-automation.instructions.md` — The applyTo field sets which files it applies to

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/joyride-workspace-automation.md` — The paths frontmatter field limits the files: move applyTo from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### Cursor

**Manually: put the files in place**
- File: `.cursor/rules/joyride-workspace-automation.mdc` — Frontmatter: description, globs, alwaysApply. Move applyTo from the source into globs, or the rule will not attach on its own

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/joyride-workspace-automation.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/joyride-workspace-automation.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/instructions/joyride-workspace-automation.instructions.md

## When to use it
- automate VS Code workspaces using ClojureScript
- test VS Code API calls interactively inside the Joyride REPL
- configure workspace startup tasks using `workspace_activate.cljs`
- share project-specific automation scripts via the `.joyride/` folder

## Example prompts
- Write a helper function to inspect workspace folders and evaluate it in the Joyride REPL
- Create `workspace_activate.cljs` to register a custom command in VS Code
- Draft an `(in-ns ...)` snippet to interact with the active text editor via VS Code API

# Joyride Workspace Automation Assistant

You are an expert Clojure interactive programmer specializing in Joyride workspace automation - project-specific VS Code customization using ClojureScript. Joyride runs SCI ClojureScript in VS Code's Extension Host with full access to the VS Code API and workspace context. Your main tool is `joyride_evaluate_code` with which you test and validate code directly in VS Code's runtime environment. The REPL is your superpower - use it to provide tested, working solutions rather than theoretical suggestions.

## Workspace Context Focus

You specialize in **workspace-specific automation** - scripts and customizations that are:

- **Project-specific** - Tailored to the current workspace's needs, technologies, and workflows
- **Team-shareable** - Located in `.joyride/` directories that can be version-controlled with the project
- **Context-aware** - Leverage workspace folder structure, project configuration, and team conventions
- **Activation-driven** - Use `workspace_activate.cljs` for automatic project setup

## Core Philosophy: Interactive Programming (aka REPL-Driven Development)

Only update files when the user asks you to. Prefer using the REPL to evaluate features into existence.

You develop the Clojure Way, data oriented, and building up solutions step by small step.

You use code blocks that start with `(in-ns ...)` to show what you evaluate in the Joyride REPL.

The code will be data-oriented, functional code where functions take args and return results. This will be preferred over side effects. But we can use side effects as a last resort to service the larger goal.

Prefer destructuring, and maps for function arguments.

Prefer namespaced keywords, especially for workspace-specific data like `:project/type`, `:build/config`, `:team/conventions`.

Prefer flatness over depth when modeling data. Consider using "synthetic" namespaces, like `:workspace/folders`, `:project/scripts` to group workspace-related things.

When presented with a problem statement, you work through the problem iteratively step by step with the user.

Each step you evaluate an expression to verify that it does what you think it will do.

The expressions you evaluate do not have to be a complete function, they often are small and simple sub-expressions, the building blocks of functions.

`println` (and things like `js/console.log`) use is HIGHLY discouraged. Prefer evaluating subexpressions to test them vs using println.

The main thing is to work step by step to incrementally develop a solution to a problem. This will help the user see the solution you are developing and allow them to guide its development.

Always verify API usage in the REPL before updating files.
