[ltk-user] Tk_Main
by Ken Tilton 26 Apr '06

26 Apr '06

Frank and I lust for OpenGL. But tcl/tk sure is handy. So: http://togl.sourceforge.net/ (requiring C programmin) and http://www.tcl3d.org/ (full Tcl scriptability) The problem with the latter is that, even with OpenGL display lists (don't ask) I think this is more traffic than we want to send over a pipe to get wicked high frame rates. And with Tcl as a separate process we cannot get to the OpenGL context from LTk. Right now Frank is trying to get an interpreter running within CL. I sent him some sample C code from Welch & Jones "Practical Programming in Tcl and Tk". Just writing to ask if there is any expertise on this list for embedding Tk. Oh, and does this sound right? Is this a typical time when folks cross over from using a pipe and switch to a C interface? Note that this is a middle ground, because most work is still done by building Tcl/tk commands and eval-ing them, but now we are running in the same process so, for example, we can use cl-opengl to build a display list which can be invoked by a Tk glCallList. I hope. :) ken

[ltk-user] SOC 2006 Proposals page revised....
by Ken Tilton 22 Apr '06

22 Apr '06

This looks a little different: http://www.lispnyc.org/soc.clp The idea is to do what we did last year, viz., have fuller descriptions of proposals backed by enthusiastic mentors. If you are one of the latter, please follow my lead: http://www.lispnyc.org/wiki.clp?page=GL-PDF-Refinement Hint: there is no space in that name for a reason. :) cl-wiki bug is being addressed, but in the meantime.... peace, kennj

[ltk-user] Job opening
by Peter Herth 04 Apr '06

04 Apr '06

Hi, there is an job opening, that might be quite interesting to the ltk users group, so I forward it to this list. If you are interested or have questions, please contact us soon. Peter Forwarded message: Cadence Design Systems GmbH in Munich, Germany ( www.cadence.com and www.cadence.com/vcad) has a job opening in the VCAD organization for an experienced software developer. It would be great to fill the position with someone who has good Lisp experience. Virtual CAD (VCAD) is a group within Cadence providing EDA (Electronic Design Automation) related services. The job is with the software development group within VCAD. Cadence's software products are scripted with the SKILL language, a Lisp language with two dialects: one Franz Lisp-like dialect, and one Scheme-like dialect. The VCAD software group also uses Common Lisp where appropriate. The position would be working in a small software group within an IC design services group. Tasks are usually related to IC design automation but not exclusively. Other current projects include release management, resource scheduling/tracking, Object-system implementation, regression/system/unit testing flow development. We are looking for someone who either has experience programming in a Lisp language, or is interested in learning Lisp in a production environment, and is comfortable in several mutually unrelated programming languages (eg, C, Smalltalk, and PostScript; or Java, Prolog, and SPARC assembly language). Experience in Perl, Python, C++, TCL, Java and Ample are useful but to a lesser extent. Experience with UNIX applications such as mySQL and Postgres would also be good. The platform is 99% UNIX based, including mostly Linux and Solaris. Other things that would be nice, but are not required: some theoretical familiarity with relational databases (eg, you took a database class or read the textbook from one); Windows programming experience; Oracle experience. Fluency in English is required. Also useful would be familiarity with German, French, Italian, Russian, or Hebrew. Relocation to Munich would be required. If you are interested, please respond to jimka(a)cadence.com. Several of my colleagues and I also plan to attend and present at the European Common Lisp Meeting in Hamburg, April 29/30. If you are interested in finding out more, please contact one of us. Thanks and happy consing, Jim Newton

[ltk-user] Tile?
by Ken Tilton 28 Mar '06

I just ran across Tk Tile. Seems to be all the rage. Also seems like it will be built into Tk 8.5. Is LTk going that way? kt

[ltk-user] Evolving Ltktest-with-cells.lisp
by Ken Tilton 26 Mar '06

26 Mar '06

I have been refining both the doc and the functionality of ltktest-with-cells (in the Celtk module under Cells), which mirrors the LTk demo ltktest, for a few days now adding more and more connectivity between the widgets and the main display, as one would have in a more real-world application. At this point I think both doc and demo are adequate, and anyway I will not know how to improve them without feedback, whether it be suggestions or requests for clarification. btw, thx to Frank for his report that all runs well on Mac OS X. I myself saw recent versions working on Lispworks+win32, albeit with a problem in that the spinning lines spun at a glacial rate. I would be interested in hearing if Celtk runs on other platforms. Now here is a big heads up: every once in a while, except when I am trying to make it happen <g>, ACL8 on win32 hangs when I close ltktest-with-cells. Possibly something to do with my Timer class run amok? We will see. ken

For Celtk, you need to get the CVS version of Celtk, which you can download from here: http://common-lisp.net/cgi-bin/viewcvs.cgi/Celtk/?root=cells by clicking on the "download tarball" link at the bottom of the page.

Under Linux it is as easy as: cvs -z3 -d :pserver:anonymous:anonymous@common-lisp.net:/project/cells/cvsroot co cells cvs -z3 -d :pserver:anonymous:anonymous@common-lisp.net:/project/cells/cvsroot co Celtk This creates the directories "cells" and "Celtk" and there you can (from time to time) say "cvs update" to get the latest stuff.

[ltk-user] Celtk\ltk-kt
by Ken Tilton 23 Mar '06

23 Mar '06

I forgot to mention that Celtk should Just Work with the official ltk, and I would build against that, but ltk classic kinda mangles error messages from Tk, and I tend to get a lot of those, so there are just a few tweaks (one?) to get the whole message legibly. Maybe those (it?) would be a good enhancement to Ltk? I noticed that I also commented out ltktest classic at some point. Not sure why, but there should be no conflict with anything in Celtk. ken

[ltk-user] Did I ask this already?
by Ken Tilton 23 Mar '06

23 Mar '06

ltktest "classic" as well as my Cells driven re-write absolutely crawls when you press Start, running Lispworks on win32. Running allegroCL on win32 both run fine. Has anyone noticed that? Suggestions? Comments? ken

[ltk-user] Celtk/Cells3 Compleat
by Ken Tilton 23 Mar '06

23 Mar '06

You can now grab Cells3 and Celtk from the c-l.net Cells repository. .\Celtk\ltktest-cells-inside.lisp has a load of doc inside it, including some on just Cells. Check out load.lisp in either source tree to build and run. (Checking next that I remembered to commit those, speaking of which, I use neither those nor ASDF when working, so they often have bugs. Speaking of which...) Bug reports or request for clarification on the doc exceedingly welcome. Otherwise, I will be getting to work on a commercial app using both these (as long as Tk holds up, which looks good so far). ken
