In C# should you have code like: public static string importantRegex = "magic!"; public void F1(){ //code if(Regex.IsMatch(importantRegex)){ //codez in here. } //more code } public void main(){ F1(); /* some stuff happens...... */ F1(); } or should you persist an instance of a Regex containing the important pattern?...

In Javascript I have defined a regular expression and now a user is typing in a string. I want to tell him if his string still could match the RegExp if he continues typing or if he's already on the wrong way. For instance: var re = /a*b/; "a".isPrefixOf( re ); // true "x".isPrefixOf( re ); // false How could an implementation of isP...
Is there a way to test if a regular expression "contains" another regular expression? For example: RegEX1 = "a.*b"; RegEx2 = "a1.*b"; RegEX1 "contains" RegEX2. As far as I know - this can't be done, am I wrong? OK, joel.neely has shown that it can be done (haven't read it yet...) academically. Can it be done in a programming language...
