Re: [Grammatica-users] Regex token order

[Oliver Bock]

I had to do a similar thing, but putting the more specific tokens first in %tokens% worked for me.  From my grammar:

ON = "ON"
VARNAME = <<address@hidden(address@hidden@])?>>

The text "ON" could match both these tokens, but for me ON matches, not VARNAME.  I suggest you cut your example down into a very simple grammar (like the above).

If I have two regex tokens A and B and A is a subset of B, how do I disambiguate them such that A will always be tried before B? The order they appear in the %tokens% section does not seem to affect this and I did not see an example of this in the documentation.

The parser I am trying to construct is for a template-like language with commands embedded in text. Thus I have a "text" token regex <<.+>> to match everything not otherwise matched as a command, but I only want to match it after all other token regex patterns have been tried.
