[developers] LKB with McCLIM graphics on Mac

[John Carroll]

Hi all,

Well, I finally have a version of the LKB for Macintosh that I’m happy for people to try out. I believe everything in the core of the LKB is functional, but LM and TSDB are not included (yet). I also haven’t tried building it in SBCL or Linux, but I don’t foresee any problems. Some of my changes will benefit the Allegro/CLIM version.

To get started:

Find a Macintosh running at least OSX 10.9
Download http://users.sussex.ac.uk/~johnca/lkb.macos_x86_64 [138MB]
Install the XQuartz X Window Server from https://www.xquartz.org
Run XQuartz, create a Terminal window, and execute lkb.macos_x86_64

The Lkb Top window should appear almost immediately. After that, all should be familiar.

I have a list of remaining issues, including:

1. Postscript output from window Print buttons is only partially correct.
2. There is no source recording.
3. Not all characters can be entered into text fields (and these respond only to the standard Emacs key bindings).

There are a few cosmetic oddities involving menus, dialogs, and window redrawing - but nothing serious I think. I attach a screenshot showing a random selection of windows.

Please give it a whirl and let me know of any problems.

Thanks!

John

If you type the full path name for the directory into the selection box, which is the suggested work around, you get the file list, though sometimes clicking doesn't work smoothly even then.  That's consistently the case in the Computer Lab systems and others have found it elsewhere too.   I think most regular users ended up using a Lisp command to load the grammar.

Although McCLIM is functionally almost complete, it’s a bit fragile if you don’t exactly play by the rules, and often the rules have to be guessed at or worked out from the source code. Also, I’ve had to       work around the unsatisfactory appearance of some things, especially windows created by accept-values. I’ve done new implementations of all of the LKB accept-values calls by explicitly programming gadgets and callbacks.

Might they be caused by having lots of mounted network filesystems, unusual structures of symbolic links, or some of the weird varieties of Microsoft file system mounting (see https://sourceforge.net/p/sbcl/mailman/message/19520335/)?

In category 2, the most widespread problems are omission of explicit define-presentation-type declarations for presentation types, and an assumption that panes are created ‘eagerly’ - whereas McCLIM does this lazily when it actually displays the window (which seems to be allowed by the spec). There’s one issue in category 3 that currently has me stumped for a work-around (changing the colour of text before a redisplay) but I’m sure I’ll figure something out.

It’s taken me around 3 days to get it working. There are still a few interface glitches and hacks I need to sort out, but the basics are there.
