BREAKING CHANGES

  • boolean flags defined without a default value will now behave like other option type and won't be set in the parsed results when the user doesn't set the corresponding CLI arg.

Previous behavior:

var parse = require('yargs-parser');

parse('--flag', {boolean: ['flag']});
// => { _: [], flag: true }

parse('--no-flag', {boolean: ['flag']});
// => { _: [], flag: false }

parse('', {boolean: ['flag']});
// => { _: [], flag: false }

New behavior:

var parse = require('yargs-parser');

parse('--flag', {boolean: ['flag']});
// => { _: [], flag: true }

parse('--no-flag', {boolean: ['flag']});
// => { _: [], flag: false }

parse('', {boolean: ['flag']});
// => { _: [] } => flag not set similarly to other option type
