DVerbalExpressions

Regular Expressions made easy

Verbal Expressions is a D module that helps to construct difficult regular expressions.

This D module is based off of the original Javascript Verbal expressions library by jehna.

Examples

Testing if we have a valid URL

// Create the class to test the regular expression
auto e = (new VerEx())
         .searchOneLine()
         .startOfLine()
         .then("http")
         .maybe("s")
         .then("://")
         .maybe("www.")
         .anythingBut(" ")
         .endOfLine();
         
// Use VerEx.test() function to find if it matches.
writefln("Match? %s", e.test("http://www.google.es") ? "yes" : "no");
