VerbalExpressions is a C++11 Header library that helps to construct difficult regular expressions.

This C++ lib is based off of the (original) Javascript VerbalExpressions library by jehna.

You can see an up to date list of all ports in our organization.

• Javascript
• Ruby
• C#
• Python
• Java
• PHP

C++11 support for regex is still poor in the standard library, you will likely need boost_regex. Download / set that up, then try the example file. Once C++ standard supports decently it will be painless to switch.

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

// Create an example of how to test for correctly formed URLs
VerEx expr = VerEx()
            .searchOneLine()
            .startOfLine()
            .then( "http" )
            .maybe( "s" )
            .then( "://" )
            .maybe( "www." )
            .anythingBut( " " )
            .endOfLine();

// Use VerEx's test() function to find if it matches
std::cout << expr.test("https://www.google.com") << std::endl;

// Ouputs the actual expression used: ^(?:http)(?:s)?(?:://)(?:www.)?(?:[^ ]*)$
std::cout << expr << std::endl;

// Create a test string
std::string replaceMe = "Replace bird with a duck";
// Create an expression that seeks for word "bird"
VerEx expr2 = VerEx().find("bird");
// Execute the expression
std::cout << expr2.replace(replaceMe, "duck") << std::endl;

std::cout << VerEx().find( "red" ).replace( "We have a red house", "blue" ) << std::endl;

Here you can find the API documentation for Verbal Expressions

Basic usage of Verbal Expressions is through a singleton, called VerEx(), that creates a new expression for you:

auto expr = VerEx();
