How to create an identifier matching the Excel cell naming rules?

Jan 22, 2014 at 7:58 PM
I would like to create an ExcelIdentifier that would match Excel-like cell references, that is,
  • (correct) A1
  • (correct) B12
  • (correct) A3B7
  • (incorrect) A0
  • (incorrect) B1A1
  • (incorrect) A7B2
Who would you proceed to do this with Irony? I have looked at the implementation of the usual C# or Python identifiers, but it does not really feel relevant.

define identifier as 'usual' and then hook to identifier.ValidateToken event and write code that validates the identifier according to your rules

Thanks a lot! It works.
