@johnca, @sweaglesw, and anyone else interested—I’m looking again at the idea of a unified configuration format for grammars. Previous thoughts and proposals are on the wiki here: GrammarConfigurationRfc · delph-in/docs …

Is there a possible way for list difference to work? (figure from: Abeillé, A., & Borsley, R. D. (2021). Basic properties and elements. Head-driven phrase structure grammar: The handbook, 3-45.) More explicitly, I am…

This is mainly a note for @sweaglesw and @johnca, but others may be interested. @Dan and @bond contacted me about a few TDL variations in NorSource that PyDelphin wasn’t able to parse. I think ACE and the LKB were able …

</div>

In token mapping, what’s the correct behaviour if a rule with one or more inputs can be applied in more than one way? For example, with the ERG’s two\_one\_tmt, if I1 matches a single edge and I2 could match two edges, the…

</div>

How do I properly say that the length of an append list is at most 1? (That’s possible, isn’t it?) I tried: clause :+ \[ SYNSEM.NON-LOCAL.QUE.LIST 0-1-list \]. But this led to a bug (which makes sense because @guyemerso…

How do I construct a complex type which has two features, one of type logical-or and the other of type logical-and (so that I could use both AND and OR operations, depending on what I need)? I am doing something wrong o…

</div>

Is it correct to say that an append list: append-list & \[ LIST \< \[\] \> \] is strictly of length one but it can be appended to, unlike a diff-list of length one? (I know we talked about this already, apologies.)

Is RELS.LIST \< \> equivalent to RELS 0-alist ? I see that @guyemerson used .LIST \< \> in his version of matrix.tdl updated with append-lists; is there a reason to prefer one to the other? 0-1-alist := append-list & \[ L…
