AceLui

Installation

See here for how to get the LUI binaries.

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:

command	description
: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/bin/ or else modify your PATH environment variable to point to the directory containing yzlui. You will probably need to change permissions for the executable (in particular, give it permission to be executed). This can be done on linux and OSX e.g. by chmod +x /usr/bin/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 macOS, you can either:

• download yzlui directly from here and follow the INSTALL instructions
• install ace and maclui via homebrew: brew install delph-in/delphin/ace delph-in/delphin/maclui

Note also that, to use the LUI mode on macOS, you need to run ACE interactively and type the sentences:

./ace -g path/to-grammar -l 

If you try to feed it a file, the LUI app will not stay open.

A few further tips for those not too familiar with Unix systems and terminal commands:

Suppose you downloaded the archive to your Desktop. You can typically expand it by double-clicking on it, but an alternative way is to open the Terminal application (use Search if you can't locate it immediately: the looking glass icon in the upper right corner) and type:

cd ~/Desktop
tar xzf yzlui-for-osx.tgz
cd yzlui-for-osx

Then to follow the instructions:

sudo cp yzlui /usr/local/bin

(it will prompt you to enter your administrator's password)

sudo cp *.dylib /usr/local/lib
sudo cp -r yzlui.app /Applications

If the last stop doesn't work, this maybe because Mac hides the extension of the file. In this case, note which file appears in the Finder as type "Application" and move it to the Applications folder manually.
