A tool to speed up the workflow of converting Commander commands to Fig completion spec files.

generateFigSpec(command, filename[, options]): void

• command: a commander.Command object
• filename: the output filename of the completion spec file
• options: an object containing the following optional properties:
  • cwd: specify the working directory in which the file will be saved. It defaults to process.cwd()

Using this library is as simple as importing a function and calling it.

import { program } from 'commander'
import { generateFigSpec } from '@withfig/commander'

program
  .name('babel')
  .description('The compiler for writing next generation JavaScript')
  .version('1.0.0')
  .argument('<file>', 'file to compile')

generateFigSpec(program, 'babel-spec.ts')

For example you may want to generate the file in an home directory subfolder for testing purpose.

import path from 'path'
import os from 'os'

...

// this will output to ~/generated/babel-spec.ts
generateFigSpec(program, 'babel-spec.ts', { cwd: path.join(os.homedir(), 'generated') })

p.s. this tool has been written for commander@8, but should work in the most of the previous versions too.
