Regular Expressions made easy

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

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

Examples

Testing if we have a valid URL

    'Create the object
    var expr = VRegex()
    with expr
        .searchOneLine()
        .startOfLine()
        ._then("http")
        .maybe("s")
        ._then("://")
        .maybe("www.")
        .anythingBut(" ")
        .endOfLine()
    end with

    if expr.test(url) then
        print url & " is a valid url."
    else
        print url & " is NOT a valid url."
    end if

    print expr
