Macros in character classes are not supported

[dscorbett]

Using a macro in a character class produces the error message “Macros in character classes are not supported.” This contradicts the documentation:

CharClassContent    ::= CharClass | Character |
                        Character'-'Character | 
                        MacroUsage | PredefinedClass

a character class [...] matches any character in that class. A Character is considered an element of a class if it is listed in the class or if its code lies within a listed character range Character’-’Character or Macro or predefined character class.

Bump.

Is there any chance of this getting fixed anytime soon?
Right now, I basically have to manually expand all of my macros, which leads to some really bad code.

I'm honestly debating whether or not I should just drop this and write a topdown lexer by hand...
I would have been done by now...

I've been looking at it and it will need a refactor of a whole bunch of code. Nothing too hard, just a lot of work. Still planning to do that, but it's definitely going to be more than 1-2 months, given that I won't have much time to actually work on it.

Ah, that's good to hear.

I thought it was just dead.
There's no rush, I've actually just spent the last hour or two restructuring the lexer so I don't have to manually expand them.
It makes it nicer in the end, so I guess it worked out in the end.

Excellent, good to hear that you're not blocked on it any more. Still planning to work on it anyway, of course.

Is there any progress with this issue? It's really bad thing right now. Even allowing macros which point to simple character classes would help design the lex input much much nicer.

Main refactor is done and first rough implementation of the feature is there. Currently in debugging.

Let me know when you need a code review.
