[cells-devel] A few patches for making cells (3.0 from cvs) run on debian unstable using sbcl.

Hello cells-devel list. I am investigating cells and cells-gtk3 for a project that I am planning. For a starter, I needed to get the software running on my Debian unstable system. It needed a few patches that you may wish to take into your development. The version of cells that I use is taken with cvs -z3 -d :pserver:anonymous:anonymous@common-lisp.net:/project/cells/cvsroot co cells That is the most actual one, yes? Well, the sbcl on Debian unstable (1.0.18) does not have nor need the EXCL package. So it must be configured out: diff -u -r cells/defpackage.lisp cl/cells/defpackage.lisp --- cells/defpackage.lisp 2008-10-12 03:21:07.000000000 +0200 +++ MDM/cl/cells/defpackage.lisp 2008-11-28 20:08:38.000000000 +0100 @@ -23,7 +23,7 @@ (in-package :common-lisp-user) (defpackage :cells - (:use #:common-lisp #:excl #:utils-kt) + (:use #:common-lisp #-sbcl #:excl #:utils-kt) (:import-from ;; MOP #+allegro #:excl diff -u -r cells/utils-kt/defpackage.lisp cl/cells/utils-kt/defpackage.lisp --- cells/utils-kt/defpackage.lisp 2008-10-12 03:21:10.000000000 +0200 +++ MDM/cl/cells/utils-kt/defpackage.lisp 2008-11-28 20:04:08.000000000 +0100 @@ -35,7 +35,8 @@ (defpackage :utils-kt (:nicknames #:ukt) - (:use #:common-lisp #:excl + (:use #:common-lisp + #-sbcl #:excl #+(or allegro lispworks clisp) #:clos #+cmu #:mop #+sbcl #:sb-mop The sbcl does not have the MOP package - it is called SB-MOP.

Worked fine, except that it is a little bit too Window'ish. I did this: diff -u -r cells/cells-test/test.lisp cl/cells/cells-test/test.lisp --- cells/cells-test/test.lisp 2008-10-12 03:21:09.000000000 +0200 +++ MDM/cl/cells/cells-test/test.lisp 2008-12-01 22:25:26.000000000 +0100 @@ -69,7 +69,7 @@ (defun test-cells () - (dribble "c:/0algebra/cells-test.txt") + (dribble "/tmp/cells-test.txt") (progn ;prof:with-profiling (:type :time) (time (progn but that is not what you want to go in the main sources. Maybe something based on the features - (dribble #+unix "/tmp/cells-test.txt" #-unix "c:/0algebra/cells-test.txt") - or perhaps just a file name parameter to TEST-CELLS with the above as the default value? Hope this is of a little help to you. I am sure to come back for assistance for my project later. best regards -- Peder Chr.

[cells-devel] tcl event loop
by Andy Chambers 16 Feb '09

16 Feb '09

In the celtk source, this message is attached to the on-key-down of the tk-object slot. "Long story. Tcl C API weak for keypress events. This gets dispatched eventually thanks to DEFCOMMAND" Do you remember what this was all about? My first thought was that perhaps tk only generated keypress events instead of splitting them into keyup/keydown but the docs on the bind command seem to suggest you can catch them seperately. What's the skinny? Cheers, Andy

[cells-devel] c-formula and setf
by Bastian Müller 16 Feb '09

16 Feb '09

Hi, I don't know if that has been discussed yet, but I've several use cases where I want to do sth. like that: A cell should be calculated by a formula if it isn't set to a value. I thought that's possible with (c-formula (:inputp t) ... ), which does calculate the slot by a formula and can be setf, but how is it possible to unset the setf value and let cells calculate it again? Example: A textbox is by default calculated by a formula. If the user enters sth. into it, that value is used. If the user clears the field of his input, the value should be calculated again. Maybe the c-formula ... approach is completely the wrong way or that's not possible at all. I've read the documentation and primer but couldn't find anything helpful. Sorry, I'm new to cells. Cheers, Bastian

[cells-devel] How to force minimum delay between events in Cells?
by Mikko Ahonen 15 Feb '09

15 Feb '09

Hello, My first cells application was in production last week. I used LispWorks, CAPI and Cells to create an application which was used to verify names for people who are coming into an exhibition opening in the biggest museum in Finland. It was an touch screen application, and contained on-screen keyboard etc. It only took few days to complete and test the program. Everything worked perfectly! I had to cut few corners from the original specification, however. The keyboard was implemented using mouse button push and release events, which displayed the proper images representing the state of the buttons (button disabled, up or down). What I wanted was to force minimum delay after button down event before button up, so the key flashes just slightly longer. Any ideas what would be the best way to accomplish this? Best regards, Mikko Ahonen

> A cell should be calculated by a > formula if it isn't set to a value. I think the easiest way to achieve that would be to just use two cells, one c? and one c-in, and just have the former be equal to the latter if it is set, and to some formula if it is not. If you really want to have a consistent interface to the slot you should consider overriding accessor methods. Regards, Jakub
