[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 21 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
