Re: [ASCEND] Ascend-sim-users Digest, Vol 50, Issue 1

[<mar...@di...>]

Hi John,
thanks for your mail. I just went the Tkinter route because I was 
interested in how the whole tcl based GUI works. It was an easy way for 
me to try it out.

I'm interested in tcl because I make music in my spare time with Pure 
data which has also a tcl based GUI.

https://en.wikipedia.org/wiki/Pure_Data

https://github.com/pure-data/pure-data


Pure Data also has a plugin to call external Python scripts:

https://github.com/grrrr/py


So I'm just experimenting a bit, learning tcl and how both ascend and 
pure data work in regard to their tcl interfaces.
And maybe I will some day in the future be able to spin out a general 
interface for both ascend and pure data.
There are some articles I've found where one could also think of doing 
this with PyGObject:

https://www.tcl.tk/community/tcl2017/assets/talk85/Paper.pdf

https://jefftrull.github.io/eda/qt/tcl/eventloop/2012/05/25/integrating-qt-tcl-event-loops.html

https://pygobject.readthedocs.io/en/latest/guide/threading.html


It's also just a little side project where I can learn how ascend worked 
back then when the Carnegie Mellon folks were working on it. I feel a 
bit like a software archaeologist when diving into the tcl code which is 
quite fun. ;)

Right now I'm stuck with "couldn't find procedure Color_Init". And I 
can't find it myself in which file this procedure ought to be.

Searching through the whole trunk branch gave no results: $ grep -Ril 
Color_Init *


Cheers,
mark
