[developers] ACE and yzlui

[Woodley Packard]

Hi Mike,

ACE automatically closes LUI when its own input stream closes.  This is sometimes not the most helpful behavior, but I find for interactive debugging it's usually pretty convenient to have all the LUI windows disappear when I exit ACE.

The intended mode of operation when LUI is being used is to run <stdin> yourself rather than echoing something through a pipe -- i.e. run ace and then type the sentence into it.  Right now there's no way to convince ACE not to close LUI down when it exits.  If you're running ACE from a script or program being the scenes, you could try leaving ACE's input open until you're done, though.  Lots of additional debugging features are available as "colon" commands, e.g. after parsing a sentence, use :c to get the chart.  Other examples of commands that are only enabled in LUI mode:

To see the expanded AVMs of various pieces of the grammar:
:r sb-hd_mc_c
:t synsem
:l sleep_v1

To compute GLBs (no GUI):
:g + -
:g arg0_relation arg12_relation

To see the local supertypes and subtypes (also no GUI):
:h head

Another fun hidden feature -- also no GUI, but it's enabled by LUI mode -- after inputting an MRS (in generation mode):
:trigger
That shows what trigger rules fired and why.  If you're curious why a particular rule didn't fire, you can get a more detailed log with:
:trigger does1_pos_rule3

Hopefully that helps get you started using the '-l' mode in ACE :-)
