Fwd: [TCLCORE] Google Summer of Code Results

[Daniel A. Steffen]

FYI, see below for the announcement about Tcl/Tk's great result in  
the 2008 Google Summer of Code slot allocation.

for more details on the GSoC Tcl/Tk projects see
        http://code.google.com/soc/2008/tcl/about.html

the Printing, Fuse and DTrace projects will be of particular interest  
to Mac users (macfuse is available for 10.4 and later c.f. http://
code.google.com/p/macfuse/ and DTrace is built into 10.5).

also note that most of the GSoC projects for MacPorts are Tcl related  
as well:
        http://code.google.com/soc/2008/macports/about.html
the MacPorts framework project should be particularly interesting.

Cheers,

Daniel

Congratulations to the students who were chosen/stepped forward to take
part in the project.

 From a cross-platform standpoint, I'd agree that the printing solution
is important. We have Mats Bengtsson's excellent printing package for
the Mac (just updated for 8.5 and using CoreGraphics), but it's not
portable.

I have to say, though, I'm disappointed no one was interested in the
Cocoa-Tk project. I think that's vitally important to Tcl's future on
the Mac (or Tk's, at least). It would be nice if Apple would contribute
some resources to such a project, as they did with the initial
Aqua/Carbon port, but it doesn't look like that will happen either.

Note that "not interested" != "felt capable", as the Cocoa-Tk was likely
next to Printing in the hardest project idea listed.  It would have been
nice to have a willing guinea pig, but no takers this time around.  ;)

However, it's not all out ... you will notice that one of the MacPorts
projects is a Tcl+Cocoa item.

That isn't the same thing as creating Tcl bindings for Cocoa as already
exist for Python and Ruby, for instance. The MacPorts Cocoa project is
specific to MacPorts' commands, and its goal is to make it easy to
create a Cocoa GUI for MacPorts that can hook directly into MacPorts
internals, without using pipes.  (My own MacPorts GUI, written in Tk,
sits on top of MacPorts' command-line tool and calls out to it via pipes.)

Last autumn I had speed shootout of Tcl vs AppleScript with a friend  
of mine in the UK. A line based input file was sorted by dividing each  
line into a list and then sorting on some criteria. In the case of  
input files about 256K Tcl handily outperformed AppleScript. However  
when the input file size grew to larger than 1 Meg, Tcl performance  
degraded (more so on PPC than Intel), and the AppleScript speed was  
better. I then translated the code into CoreFoundation. For CF, the  
speed was always between 1/5th - 1/10th of the fastest script.

Just recently I saw this:
<http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=all>

So I'm wondering if Tcl performance issues ever come up as a  
consideration for improvement?

I have not checked it out yet, but the person that works on it can  
feel free to contact me and work with that I am dong as well. This  
port is already a lot of fun.

Thanks for pointing this out.  We should definitely have some contact
with them over the summer.

The Tclish bit of the MacPorts framework is (I think) mostly worked
out in a prototype framework. See
http://trac.macosforge.org/projects/macports/browser/users/rhwood/MacPorts.Framework/MPInterpreter.m

This is specific to MacPorts of course, but could be easily made a
little more generic.
