Grove Development

Project Stack

• Runtime: Bun
• Language: TypeScript (strict mode)
• CLI Framework: Commander.js
• Git Operations: simple-git library
• Testing: Bun's built-in test runner

Development Workflow

Before committing

bun run typecheck   # Type check
bun test            # Run all tests

Common commands

bun install         # Install dependencies
bun run dev         # Run in development mode
bun run build       # Build to dist/
bun run build:compile  # Build single executable

Code Patterns

Adding a new command

1. Create src/commands/<name>.ts with factory function:

import { Command } from "commander";
import { handleCommandError } from "../utils";

export function create<Name>Command(): Command {
  return new Command("<name>")
    .description("Short description")
    .argument("<arg>", "Argument description")
    .option("-f, --flag", "Flag description")
    .action(async (arg, options) => {
      try {
        // Implementation
      } catch (error) {
        handleCommandError(error);
      }
    });
}

2. Register in src/index.ts:

import { create<Name>Command } from "./commands/<name>";
program.addCommand(create<Name>Command());

Git operations

Use WorktreeManager class instead of calling git directly:

const manager = await WorktreeManager.discover();
// Use manager methods for git operations

Error handling

import { formatError, formatWarning, handleCommandError } from "../utils";
// In action handlers, wrap with try/catch calling handleCommandError

Interfaces

Define in src/models/index.ts

Testing

Structure

• Unit tests: test/unit/*.test.ts - Uses Bun's built-in test runner
• Integration tests: test/integration/*.hone - Uses Hone CLI testing framework

Unit test pattern

import { describe, test, expect, mock } from "bun:test";

describe("FeatureName", () => {
  test("should do something", () => {
    expect(result).toBe(expected);
  });
});

Running tests

bun test              # Unit tests only
bun run test:integration  # Builds executable, runs Hone tests

Commit Messages

Use Conventional Commits format:

<type>: <subject>

Types: feat, fix, chore, test, doc

Rules:

• Lowercase type and subject
• No period at end
• Imperative mood ("add" not "added")
• Under 72 characters

Examples:

feat: add support for branch tracking
fix: handle missing git config gracefully
chore: update dependencies
test: add edge case tests for prune
doc: update readme with new command

Documentation

When adding/changing commands:

1. Update README.md Commands section
2. Update site/index.html to match (keep in sync)

Platform Support

Linux and macOS only (x64, arm64). No Windows code.
