const yaml = require('yamljs')
const fs = require('fs')

const directory = process.argv[2] || '.'

fs.readdirSync(directory)
  .filter(f => f.endsWith('.yaml'))
  .map(f => f.substring(0,f.indexOf('.yaml')))
  .forEach((name) => {
    const fromYaml = yaml.load(name + '.yaml')
    const json = JSON.stringify(fromYaml,null,2)
    fs.writeFile(name + '.json', json, () => {console.log(`Converted ${name}.yaml`)})
