|
| 56 | * Creates a real stream out of an ASCII drawing of a stream. Each string
|
| 57 | * character represents an amount of time passed (by default, 20 milliseconds).
|
| 58 | * `-` characters represent nothing special, `|` is a symbol to mark the
|
| 59 | * completion of the stream, `#` is an error on the stream, and any other
|
| 60 | * character is a "next" event.
|
| 61 | *
|
| 62 | * Example:
|
| 63 | *
|
| 64 | * ```js
|
| 65 | * import fromDiagram from 'xstream/extra/fromDiagram'
|
| 66 | *
|
| 67 | * const stream = fromDiagram('--a--b---c-d--|')
|
| 68 | *
|
| 69 | * stream.addListener({
|
| 70 | * next: (x) => console.log(x),
|
| 71 | * error: (err) => console.error(err),
|
| 72 | * complete: () => console.log('concat completed'),
|
| 73 | * })
|
| 74 | * ```
|
| 75 | *
|
| 76 | * The character `a` represent emission of the event `'a'`, a string. If you
|
| 77 | * want to emit something else than a string, you need to provide those values
|
| 78 | * in the options argument.
|
| 79 | *
|
| 80 | * Example:
|
| 81 | *
|
| 82 | * ```js
|
| 83 | * import fromDiagram from 'xstream/extra/fromDiagram'
|
| 84 | *
|
| 85 | * const stream = fromDiagram('--a--b---c-d--|', {
|
| 86 | * values: {a: 10, b: 20, c: 30, d: 40}
|
| 87 | * })
|
| 88 | *
|
| 89 | * stream.addListener({
|
| 90 | * next: (x) => console.log(x),
|
| 91 | * error: (err) => console.error(err),
|
| 92 | * complete: () => console.log('concat completed'),
|
| 93 | * })
|
| 94 | * ```
|
| 95 | *
|
| 96 | * That way, the stream will emit the numbers 10, 20, 30, 40. The `options`
|
| 97 | * argument may also take `timeUnit`, a number to configure how many
|
| 98 | * milliseconds does each represents, and `errorValue`, a value to send out as
|
| 99 | * the error which `#` represents.
|
| 100 | *
|
| 101 | * @factory true
|
| 102 | * @param {string} diagram A string representing a timeline of values, error,
|
| 103 | * or complete notifications that should happen on the output stream.
|
| 104 | * @param options An options object that allows you to configure some additional
|
| 105 | * details of the creation of the stream.
|
| 106 | * @return {Stream}
