angular-regex

VerbalExpressions is a Angular library that helps to construct difficult regular expressions.

Install

Install with Bower or download the the files directly from the dist folder in the repo.

bower install angular-regex

Add dist/angular-regex.service.min.js index.html.

Add regex as a module dependency for your module.

Then inject and use the regexService service.

Examples

Here's a couple of simple examples to give an idea of how VerbalExpressions works:

Testing if we have a valid URL

// Create an example of how to test for correctly formed URLs
function myController($scope,regexService){  // <-- Inject regexService

var tester = regexService.ex()
    .startOfLine()
    .then('http')
    .maybe('s')
    .then('://')
    .maybe('www.')
    .anythingBut(' ')
    .endOfLine();

// Create an example URL
var testMe = 'https://www.google.com';

// Use RegExp object's native test() function
if (tester.test(testMe)) {
    alert('We have a correct URL '); // This output will fire}
} else {
    alert('The URL is incorrect');
}

console.log(tester); // Outputs the actual expression used: /^(http)(s)?(\:\/\/)(www\.)?([^\ ]*)$/

Replacing strings

// Create a test string
var replaceMe = 'Replace bird with a duck';

// Create an expression that seeks for word "bird"
var expression = regexService.ex().find('bird');

// Execute the expression like a normal RegExp object
var result = expression.replace(replaceMe, 'duck');

// Outputs "Replace duck with a duck"
alert(result);

Shorthand for string replace:

var result = regexService.ex().find('red').replace('We have a red house', 'blue');

// Outputs "We have a blue house"
alert(result);

A little word for a big help

I'd like to promote a special thank-you to Ben Nadel for his great article about extending native JS objects
