Package Exports

@stdlib/string-base-replace
@stdlib/string-base-replace/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/string-base-replace) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

replace

Replace search occurrences with a replacement string.

Installation

npm install @stdlib/string-base-replace

Usage

var replace = require( '@stdlib/string-base-replace' );

replace( str, search, newval )

Replaces search occurrences with a replacement string.

var out = replace( 'beep', /e/g, 'o' );
// returns 'boop'

If provided a function as the third argument, the function is invoked for each match, and the function's return value is used as the replacement string.

function replacer( match, p1 ) {
    return '/' + p1 + '/';
}
var str = 'Oranges and lemons';
var out = replace( str, /([^\s]+)/gi, replacer );
// returns '/Oranges/ /and/ /lemons/'

Notes

The function assumes that the search argument is a regular expression. Accordingly, the function should not be used as a general drop-in replacement for String.prototype.replace.

Examples

var capitalize = require( '@stdlib/string-base-capitalize' );
var replace = require( '@stdlib/string-base-replace' );

var out = replace( 'Hello World', /world/i, 'Mr. President' );
// returns 'Hello Mr. President'

function replacer( match, p1 ) {
    return capitalize( p1 );
}
var str = 'Oranges and lemons say the bells of St. Clement\'s';
out = replace( str, /([^\s]*)/gi, replacer );
// returns 'Oranges And Lemons Say The Bells Of St. Clement\'s'
