About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

untilAsync

Invoke a function until a test condition is true.

Installation

1npm install @stdlib/utils-async-until

Usage

1var untilAsync = require( '@stdlib/utils-async-until' );

untilAsync( predicate, fcn, done[, thisArg ] )

Invokes a function until a predicate function returns true.

1function predicate( i, clbk ) {
2    clbk( null, i >= 5 );
3}
4
5function fcn( i, next ) {
6    setTimeout( onTimeout, 0 );
7    function onTimeout() {
8        console.log( 'beep: %d', i );
9        next();
10    }
11}
12
13function done( error ) {
14    if ( error ) {
15        throw error;
16    }
17}
18
19untilAsync( predicate, fcn, done );
20/* =>
21    beep: 0
22    beep: 1
23    beep: 2
24    beep: 3
25    beep: 4
26*/

The predicate function is provided two arguments:

i: iteration number (starting from zero)
clbk: a callback indicating whether to invoke fcn

The clbk function accepts two arguments:

error: error object
bool: test result

If the test result is falsy, the function invokes fcn; otherwise, the function invokes the done callback.

The function to invoke is provided two arguments:

i: iteration number (starting from zero)
next: a callback which must be invoked before proceeding to the next iteration

The first argument of both clbk and next is an error argument. If either function is called with a truthy error argument, the function suspends execution and immediately calls the done callback for subsequent error handling.

1function predicate( i, clbk ) {
2    clbk( null, i >= 5 );
3}
4
5function fcn( i, next ) {
6    setTimeout( onTimeout, 0 );
7    function onTimeout() {
8        next( new Error( 'beep' ) );
9    }
10}
11
12function done( error ) {
13    console.error( error.message );
14    // => beep
15}
16
17untilAsync( predicate, fcn, done );

The done callback is invoked with an error argument and any arguments passed to the final next callback.

1function predicate( i, clbk ) {
2    clbk( null, i >= 5 );
3}
4
5function fcn( i, next ) {
6    setTimeout( onTimeout, 0 );
7    function onTimeout() {
8        next( null, i );
9    }
10}
11
12function done( error, result ) {
13    if ( error ) {
14        throw error;
15    }
16    console.log( result );
17    // => 4
18}
19
20untilAsync( predicate, fcn, done );

To set the function execution context for the invoked function, provide a thisArg.

1function predicate( i, clbk ) {
2    clbk( null, i >= 5 );
3}
4
5function fcn( i, next ) {
6    this.count += 1;
7    setTimeout( onTimeout, 0 );
8    function onTimeout() {
9        next();
10    }
11}
12
13var context = {
14    'count': 0
15};
16
17untilAsync( predicate, fcn, done, context );
18
19function done( error ) {
20    if ( error ) {
21        throw error;
22    }
23    console.log( context.count );
24    // => 5
25}

Notes

Execution is not guaranteed to be asynchronous. To guarantee asynchrony, wrap the done callback in a function which either executes at the end of the current stack (e.g., nextTick) or during a subsequent turn of the event loop (e.g., setImmediate, setTimeout).

Examples

1var repeatString = require( '@stdlib/string-repeat' );
2var untilAsync = require( '@stdlib/utils-async-until' );
3
4function predicate( i, clbk ) {
5    setTimeout( onTimeout, 0 );
6    function onTimeout() {
7        clbk( null, i >= 5 );
8    }
9}
10
11function fcn( i, next ) {
12    setTimeout( onTimeout, 0 );
13    function onTimeout() {
14        next( null, repeatString( 'beep', i+1 ) );
15    }
16}
17
18function done( error, result ) {
19    if ( error ) {
20        throw error;
21    }
22    console.log( result );
23}
24
25untilAsync( predicate, fcn, done );
