oparser v3.0.22

oparser

A very forgiving key-value option parser.

Converts plain text key-value pairs to useable javascript objects.

See oparser.test.js for more usage examples.

Install

npm install oparser

Example

Handles single & multiline complex strings of key-value pairs

/* String */
const str = parse(`name=bob`)
const str = parse(`name='bob'`)
const str = parse(`name="bob"`)
const str = parse(`name={bob}`)
/* > output js object
{ name: 'bob' }
*/

const multipleValues = optionsParse(`a='foo' b="bar" c=zaz`)
/* > output js object
{ a: 'foo', b: 'bar', c: 'zaz' }
*/

/* Boolean */
const bool = parse(`isCool`)
const bool = parse(`isCool = true`)
const bool = parse(`isCool =true`)
const bool = parse(`isCool=true`)
const bool = parse(`isCool={true}`)
const bool = parse(`isCool={{true}}`)
/* > output js object
{ isCool: true }
*/

/* Arrays */
const arrayWithNumbers = parse(`key=[ 1, 2, 3 ]`)
/* > output js object
{ key: [ 1, 2, 3 ] }
*/

const arrayWithStrings = parse(`key=[ "1", "2", "3" ]`)
/* > output js object
{ key: [ "1", "2", "3" ] }
*/

const arrayWithNonQuotedStrings = parse(`key=[ one, two, three ]`)
/* > output js object
{ key: [ "one", "two", "three" ] }
*/

const arrayWithMixedValues = parse(`
great={["scoot", "sco ot", 'scooo ttt', one, two, 3, 4, true]} 
`)
/* > output js object
{ great: [ 'scoot', 'sco ot', 'scooo ttt', 'one', 'two', 3, 4, true ] }
*/

/* Objects */
const obj = parse(`key={{ "a": "b" }}`)
const obj = parse(`key={{ "a": b }}`)
const obj = parse(`key={{ a: "b" }}`)
const obj = parse(`key={{ a: b }}`)
const obj = parse(`key={ a : b }`)
/* > output js object
{ key: { a: 'b' }}
*/

/* Multiline Objects */
const reactStyleObjects = `
  foo={{
    baz: {
      bar: {
        fuzz: "hello"
      }
    }
  }}
`
console.log(parse(reactStyleObjects))
/* > output js object
{
  foo: {
    baz: {
      bar: {
        fuzz: "hello"
      }
    }
  }
}
*/
