Haxe VerbalExpressions

Haxe Regular Expressions made easy

VerbalExpressions is a Haxe library that helps to construct difficult regular expressions. Ported from the awesome JavaScript VerbalExpressions. This project wraps around the Haxe EReg class.

Getting started

Clone the project or download the sources.

Basic usage of Verbal Expressions is trough new expressions.VerbalExpression():

var myExpression = new expressions.VerbalExpression();

Examples

Testing valid URLs

var expression = new expressions.VerbalExpression()
  .startOfLine()
  .then("http")
  .maybe("s")
  .then("://")
  .maybe("www.")
  .anythingBut(" ")
  .endOfLine();

var url = "https://www.haxe.org/";
// test if the url matches
if (expression.isMatch(url)) {
  trace('$url is a valid URL');
} else {
  trace('$url is an invalid URL');
}

trace(expression.toString()); 
// logs the regular expression source: ^(http)(s)?(://)(www.)?([^{ }]*)$

expression.toRegex(); 
// the Haxe EReg instance

Replacing strings

var result:String = new expressions.VerbalExpression()
    .find("bird")
    .replace("Replace bird with a duck", "duck");
    
trace(result); 
// logs "Replace duck with a duck"
