[mcclim-devel] Displaying non-ASCII characters in McCLIM using SBCL
by Milan Zamazal 20 Jun '05

20 Jun '05

The following patch makes McCLIM/CLX to display accented characters with SBCL 0.9.1.1. This is only a raw proof-of-concept patch, not a patch to be actually applied. Additionally, I tested it only with ISO 8859-2 characters. Could somebody of the McCLIM experts look at it and make the necessary changes in McCLIM/CLX, please? Thanks. Input of non-ASCII characters still doesn't work. Milan Zamazal -- real programmer? don't get me started. if you need to hide your pathetic excuse for a carreer behind super-macho languages like C, C++, and/or Perl instead of writing clean, maintainable, efficient code, you aren't much of a real programmer in my view. -- Erik Naggum in comp.emacs

[mcclim-devel] incremental redisplay optimization(?)
by Christophe Rhodes 17 Jun '05

17 Jun '05

Hi, The new(ish) code for optimizing incremental redisplay by replaying move-overlapping and erase-overlapping records all at once is actually a huge pessimization for many disconnected records: I think that region-union is a precise operation, so the asymptotic complexity of the union operation is O(n^2), and I think the complexity of the replay is O(n^3). Specifically, for my tablature editor, an operation which causes most records to be redraw takes 200 seconds with the current code, with most time (about 77%) being spent in BANDS-OP. The attached fixes the performance problem by being a little less precise. Is it right? Cheers, Christophe

[mcclim-devel] pointer protocol class / standard-pointer
by Christophe Rhodes 16 Jun '05

16 Jun '05

Hi, At present, it's only possible to have one backend loaded at once, because STANDARD-POINTER is defined per-backend. This can't be right, can it? On the other hand, the attached is my 'solution' (for the CLX backend; I haven't tried fiddling with Beagle, but this also works for my in-development Null backend), and I'm not wild about it. Still. Any opinions? Cheers, Christophe

[mcclim-devel] [patch] bug in map-over-command-table-keystrokes?
by Daniel Barlow 15 Jun '05

15 Jun '05

I noticed this while trying to persuade climacs to give me a list of keybindings: (map-over-command-table-keystrokes (lambda (name key item) (format t "~A ~A ~A~%" name key item)) 'CLIMACS-GUI::GLOBAL-CLIMACS-TABLE) => debugger invoked on a UNBOUND-SLOT in thread 11974: The slot CLIM-INTERNALS::MENU-NAME is unbound in the object #<MENU-ITEM keystroke (- META) {9794829}>. According to the specification 27.4, "function must be a function of three arguments, the menu name (which will be nil if there is none), the keystroke accelerator, and the command menu item". I don't know if the fix below is the Right Thing, but it does the trick for me.

[mcclim-devel] Beagle backend requirements?
by Brian Mastenbrook 10 Jun '05

10 Jun '05

Hi Duncan, What version of OpenMCL is required for running the Beagle backend? Right now current CVS won't run on 0.14.3 with an error about ObjC ARRAY. Should I get bleeding edge or current 0.14 CVS? Thanks! -- Brian Mastenbrook http://www.iscblog.info/ http://www.cs.indiana.edu/~bmastenb/

[mcclim-devel] Freetype for SBCL
by Brian Mastenbrook 09 Jun '05

09 Jun '05

Hello, Since I'm under the impression that code in the Experimental directory is, well, experimental, I've committed a version of the experimental freetype bindings which works on SBCL. I've optimized away the %SAP-ALIEN problems, and the end product is reasonably usable. It's a bit laggy until the glyph cache warms up, but after that it's just fine. Here's a gratuitous screenshot: http://www.unmutual.info/images/slidemacs-big.png I'm pretty sure that this doesn't work on CMUCL anymore, as CMUCL has slightly different names (DEF-ALIEN-TYPE and -ROUTINE), but a little macrology should restore CMUCL workingness if anybody's interested in giving it a try. In order to use this under SBCL, you must use the .asd file, as there's a little ASDF muckery in there to work around the fact that compiling the freetype-ffi file currently stuffs up in SBCL. After the rest of the code finishes compiling, you should see a message about setting mcclim-freetype:*freetype-font-path* - set this to a directory containing the Bitstream Vera fonts, and don't forget the final / on the pathname or else merge-pathnames is not going to be happy. Comments and patches welcome, especially from CMUCL users. -- Brian Mastenbrook "God made the natural numbers; http://www.iscblog.info/ all else is the work of man." chandler(a)unmutual.info -- Leopold Kroneker

[mcclim-devel] First native pane type in Beagle
by Duncan Rose 05 Jun '05

05 Jun '05

For anybody interested I've put a couple of screen shots of the Listener with a first-pass at native scroll bars up on my webspace: http://www.robotcat.demon.co.uk/ I realize there are few people able to run Beagle at the moment unfortunately :-( As an aside, if anybody can give me a couple of pointers as to how exactly the 'scroller-pane' decides whether to lay the vertical scroll bar out on the left side or the right side I'd be grateful. I can't see anything that obviously controls this. On a final note, does McCLIM take any notice of key event object's :key-name as opposed to :key-character? Is there a way to set up a command (for Goatee, say) that makes :LEFT behave the same as ctrl-b? Thanks, -Duncan
