🚨 Critical Rules

1. Stack: CommonJS (require). NO ESM.
2. Core Libs:
   • Use const Ec = require('../epic'); for logging/flow.
   • Use const Utils = require('../utils/momo-*'); for helpers.
3. Interactive: MUST use require('../utils/momo-menu'). NO raw readline.
4. Style: Use Ec for all logging.

📂 Architecture

• Config: src/commander/{cmd}.json
• Executor: src/executor/execute{Cmd}.js
• Utils: src/utils/ (momo-fs, momo-menu, momo-args)

📝 Config Schema (JSON)

Copy{
  "executor": "executeName", "command": "name", "description": "desc",
  "options": [{ "name": "arg", "alias": "a", "type": "string" }]
}

💻 Executor Template(Native)

Copyconst Ec = require('../epic');
const Args = require('../utils/momo-args');
const FS = require('../utils/momo-fs');
const { selectSingle } = require('../utils/momo-menu');

module.exports = async (options) => {
    try {
        // 1. Parsing
        const opts = Args.parseStandard(options);
        const target = Args.parsePositional()[0];

        // 2. Logic
        Ec.waiting('Working...');
        if (!FS.exists(target)) Ec.error('Path not found');

        // 3. Menu Example
        const item = await selectSingle([{name: 'Go'}], 'Title');
        if(!item) process.exit(0);

        // 4. Finish
        Ec.info('✅ Done');
        process.exit(0);
    } catch (e) { Ec.error(e.message); process.exit(1); }
};

📚 API Reference (Project Context)

1. File System ( momo-fs.js )

Combines file-utils and yaml-parser.

Copyconst FS = require('../utils/momo-fs');
// Methods:
ensureDir(path), exists(path), readJson(path), writeJson(path, data)
copyDir(src, dest), scanDir(dir, filterFn?), createTempDir(prefix?)
cleanup(path), gitClone(url, dest)
parseFile(path) // YAML Frontmatter

2. Interactive Menu ( momo-menu.js )

Copyconst { selectMultiple, selectSingle, clearScreen } = require('../utils/momo-menu');
// selectMultiple returns { indices: [], items: [] }
// selectSingle returns Item | null

3. Argument Parser ( momo-args.js )

Copyconst Args = require('../utils/momo-args');
// Methods:
parseStandard(options) // Standard KV
parseOptional(flag, alias)
parseBool(flag, alias)
parsePositional()

4. Core (../epic)

Ec.info/warn/error/waiting(msg)

await Ec.ask(query) (Use only AFTER menu closes)

String colors: .green, .blue, .bold, etc.
