Hello Saaa,
You have to write it yourself. Here's a good starting point: http://www.digitalmars.com/d/1.0/lex.html#identifierYes, that was my starting point and it seemed quite complex, thus my question :) I think I'll stay with my simple check for now as it isn't really necessary to be as strict as D's identifiers. Just thought that if there was an easy check I'd implement that. Thanks anyways everybody.
if you are only working with ASCII: use the regex `_A-Za-z[_A-Za-z0-9]*`
