Debugging Features in LUI mode

The LUI mode can be activated with the -l option, assuming yzlui exists on PATH (also see AceFaq). While in LUI mode, lots of additional debugging features are available as "colon" commands:

• :c	get the parse chart of the last processed item
  :r rule	display the AVM of a grammar rule (e.g. :r sb-hd_mc_c)
  :t type	display the AVM of a grammar type (e.g. :t synsem)
  :l lex-entry	display the AVM of a lexical entry (e.g. :l sleep_v1)
  :g one two	compute the GLB of types one and two (e.g. :g + -); results will be shown as text, not in a GUI
  :h type	show the local supertypes and subtypes of type (e.g. :h head); also shown as text
  :trigger [rule]	in generation mode, show which trigger rules fired and why; when rule is provided (e.g. :trigger does1_pos_rule3) , it will show more information about the particular rule (including why an unused rule didn't fire); results are shown as text

Getting the yzlui binary on your PATH

On Linux, you can get the yzlui binary from within the LOGON tree. You'll need to copy it to somewhere like /usr/local/bin/ or else modify your PATH environment variable to point to the directory containing yzlui. You can also download a (relatively recent but not necessarily maximally up to date) yzlui binary from here (again, it will need to be renamed 'yzlui' and put somewhere visible to PATH).

On MacOSX, the situation is slightly more complex and much less tested. Download yzlui for OSX here, and follow the INSTALL instructions. Good luck!
