YY input and double quotes as tokens

If a token is a double quote, what does ACE expect in YY-input? This?

(1, 0, 1, <0:1>, 1, "\"" "\"", 0, "fe", "fe" 1.0) 

If so, does anyone know how do I write that literally into a file if I assemble the string step by step and the double quotes come from variables which have the value '"'? No matter what I do, the file ends up either with zero backslashes or with two of them…

Nevermind; I think it wants "\\"", as is proper (and writeable).

Hmm. When I call ACE directly on:

(1, 0, 1, <0:1>, 1, "\\"" "\\"", 0, "fe", "fe" 1.0) (2, 1, 2, <1:5>, 1, "algo" "algo", 0, "pi0cs00", "pi0cs00" 0.8544207317073171) (3, 2, 3, <6:13>, 1, "puntual" "puntual", 0, "aq0cs00", "aq0cs00" 1.0) (4, 3, 4, <13:14>, 1, "\\"" "\\"", 0, "fe", "fe" 1.0) (5, 4, 5, <14:15>, 1, "." ".", 0, "fp", "fp" 1.0)

I get an error:

expected ',', but input is \\"", 0, "fe", "

But if I use the exact same string as part of the item file that I process with pydelphin ACE wrapper, I get:

77/177NOTE: lexemes do not span position 0 `"'!

The second behavior is better although I still don’t know how to parse the quote; in the lexicon, it appears as:

quotes_pt := pt_-_quots_le & 
   [ STEM < "\"" > ].

ACE wants to see it with a single backslash, as you originally supposed. It requires an additional layer of escaping when it’s in the tsdb profile, but pydelphin is (presumably) unescaping it before passing it to ACE. I can’t guess why the lexical entry you showed isn’t being instantiated though.
