Tokenizing within continuous strings

[hberge]

I have "zid" strings in my DSL which can't contain spaces, and can look like these examples:

name
name_{refa}_{refb}_suffix
{prefix}_name[{id}:0][1:0]

Is there a good way to match such a string without whitespace, but tokenize it further so I can get the references within braces?

The only way I can think of is to write a regular expression that matches a ZID terminal first, then post-process that after. Perhaps with another grammar just for that. Is that a good way to do it?

Yes, post-processing is the best way to do it, afaik. I don't think you need another grammar, probably a regex will be enough.
