Question

I need to replace upper case letter in variable name with lower case letter and add space

For example:

NotImplementedException should be Not implemented exception
UnhandledException should be Unhandled exception

Answer 1

Since you did not specify a language, I’ll give an example in C#. I am sure your language will offer something like it.

String s = "NotImplementedException";
s = Regex.Replace(s, @"\B[A-Z]", m => " " + m.ToString().ToLower());
// s = "Not implemented exception"
