| # dargs [](https://travis-ci.org/sindresorhus/dargs)
|
| > Reverse [`minimist`](https://github.com/substack/minimist). Convert an object of options into an array of command-line arguments.
|
| Useful when spawning command-line tools.
|
|
| ## Install
|
| ```
| $ npm install dargs
| ```
|
|
| ## Usage
|
| ```js
| const dargs = require('dargs');
|
| const input = {
| _: ['some', 'option'], // Values in '_' will be appended to the end of the generated argument list
| '--': ['separated', 'option'], // Values in '--' will be put at the very end of the argument list after the escape option (`--`)
| foo: 'bar',
| hello: true, // Results in only the key being used
| cake: false, // Prepends `no-` before the key
| camelCase: 5, // CamelCase is slugged to `camel-case`
| multiple: ['value', 'value2'], // Converted to multiple arguments
| pieKind: 'cherry',
| sad: ':('
| };
|
| const excludes = ['sad', /.*Kind$/]; // Excludes and includes accept regular expressions
| const includes = ['camelCase', 'multiple', 'sad', /^pie.*/];
| const aliases = {file: 'f'};
|
| console.log(dargs(input, {excludes}));
| /*
| [
| '--foo=bar',
| '--hello',
| '--no-cake',
| '--camel-case=5',
| '--multiple=value',
| '--multiple=value2',
| 'some',
| 'option',
| '--',
| 'separated',
| 'option'
| ]
| */
|
| console.log(dargs(input, {excludes, includes}));
| /*
| [
| '--camel-case=5',
| '--multiple=value',
| '--multiple=value2'
| ]
| */
|
|
| console.log(dargs(input, {includes}));
| /*
| [
| '--camel-case=5',
| '--multiple=value',
| '--multiple=value2',
| '--pie-kind=cherry',
| '--sad=:('
| ]
| */
|
|
| console.log(dargs({
| foo: 'bar',
| hello: true,
| file: 'baz'
| }, {aliases}));
| /*
| [
| '--foo=bar',
| '--hello',
| '-f', 'baz'
| ]
| */
| ```
|
|
| ## API
|
| ### dargs(input, [options])
|
| #### input
|
| Type: `Object`
|
| Object to convert to command-line arguments.
|
| #### options
|
| Type: `Object`
|
| ##### excludes
|
| Type: `Array`
|
| Keys or regex of keys to exclude. Takes precedence over `includes`.
|
| ##### includes
|
| Type: `Array`
|
| Keys or regex of keys to include.
|
| ##### aliases
|
| Type: `Object`
|
| Maps keys in `input` to an aliased name. Matching keys are converted to arguments with a single dash (`-`) in front of the aliased key and the value in a separate array item. Keys are still affected by `includes` and `excludes`.
|
| ##### useEquals
|
| Type: `boolean`<br>
| Default: `true`
|
| Setting this to `false` makes it return the key and value as separate array items instead of using a `=` separator in one item. This can be useful for tools that doesn't support `--foo=bar` style flags.
|
| ###### Example
|
| ```js
| console.log(dargs({foo: 'bar'}, {useEquals: false}));
| /*
| [
| '--foo', 'bar'
| ]
| */
| ```
|
| ##### ignoreFalse
|
| Type: `boolean`<br>
| Default: `false`
|
| Exclude `false` values. Can be useful when dealing with strict argument parsers that throw on unknown arguments like `--no-foo`.
|
| ##### allowCamelCase
|
| Type: `boolean`<br>
| Default: `false`
|
| By default, camelCased keys will be hyphenated. Enabling this will bypass the conversion process.
|
| ###### Example
|
| ```js
| console.log(dargs({fooBar: 'baz'}));
| //=> ['--foo-bar', 'baz']
|
| console.log(dargs({fooBar: 'baz'}, {allowCamelCase: true}));
| //=> ['--fooBar', 'baz']
| ```
