Re: [Pythonmac-SIG] py2app & multiprocessing
Hi again,
I think using multiprocessing should be the way to go, so that you use
twisted for the main event loop in one process, and wx for the main
event loop in the other.
In a simple way, you can also build your own custom multiprocessing
tool. You just need one system calls, and one network connection. (for
controlling the other process) Like this :
pid = os.fork()
if pid == 0: # child
# no need to call os.execv(), since your code is in python
# open TCP socket as a receiver
# start event loop
else: # child
child_pid = pid
# open TCP socket as a sender
# start event loop
...and no, I am not using twistd. For now, I prefer not to rely on any
other executable, and start the main loop in my app.
reactor.run()
You can also look at some other free software I am working on :
* Lunch : https://svn.sat.qc.ca/trac/postures/wiki/Lunch
* ToonLoop : http://www.toonloop.com/
* Miville : https://svn.sat.qc.ca/trac/miville
* RawMaterials : https://svn.sat.qc.ca/trac/rawmaterials
They all use twisted, but RawMaterials is the only for Mac. (the code
is rather old and should be updated.) ToonLoop should be ported to mac
with a app bundle soon. It is a live stop motion software, which is
also the topic of my master.
What does your application do ? Is it free software as well ?
Ciao,

Re: [Pythonmac-SIG] py2app & multiprocessing
Hi everyone,
I use Twisted everyday, and have worked on a wx GUI for an application
using it. We also use Py2App to bundle it up. It works flawlessly. I
use the Twisted main loop, which controls the wx events loop.
To make both of them work together, you need to do the following :
{{{
from twisted.internet import wxreactor
wxreactor.install()
}}}
You can check our RawMaterials application since it is free software.
It has a lot of dependencies, so it is rather difficult to build.
https://svn.sat.qc.ca/trac/rawmaterials/browser/trunk/src/RawMaterials.py
We use a shell script to build and copy things in the .app :
https://svn.sat.qc.ca/trac/rawmaterials/browser/trunk/src/make_app.sh
I would say the problem is probably more about multiprocessing than wx
and twisted. Using subprocess, or pexpect, or commands might be a
better idea.

Re: [Pythonmac-SIG] run python script on another computer's terminal (LAN)
Hi! Do you want to see the output in the remote computer's display? If so, screen might help you. You could also use the "open" command to open the Terminal supplying it a command. The "xterm" terminal in X11 is nice for that. (or better: rxvt) If you just want to get the resulting output, use either subprocess, commands or pxssh ! Anyways, ssh is the way to go. You can look at my "lunch" script for inspiration. https://svn.sat.qc.ca/trac/postures/wiki/Lunch a 2009/8/11 Nicholas Riley : > On Tue, Aug 11, 2009 at 03:35:21PM -0400, Chris Rebert wrote: >> What is "eppc://"?

Re: [Pythonmac-SIG] Fink vs MacPorts vs Framework
Hi ! Seems to me there are a lot of python packages that are available through the MacPorts. In the built-in framework, there are only a few basic packages. Fink gives the same benefits than MacPorts, but there might be fewer packages available though it than through MacPorts. That's why I use MacPorts. Is this right ? a 2009/6/30 Dan Ross : > I currently use a Framework of 2.6.2 for my Python work but I always see a > lot of posts about using Fink or MacPorts builds. > > Could anyone shed some light on why they use these rather than a Framework? > > Advantages/disadvantages? > > Thanks, > > Dan > > ___ > Pythonmac-SIG maillist - pythonmac-...@python.org > http://mail.python.org/mailman/listinfo/pythonmac-sig > -- Alexandre Quessy http://alexandre.quessy.net/ ___ Pythonmac-SIG maillist - Pythonmac-SIG@python.org http://mail.python.org/mailman/listinfo/pythonmac-sig
Re: [Pythonmac-SIG] Unable to run python application
Hi beegee ! "/* */" as a comments delimiter is not supported in Python. The simplest way to create comments in Python is to begin each comment line with a #. You can also use triple-delimited strings for documentation. a 2009/4/15 Ned Deily : > In article > <7122b8730904151138o3a0cb401hbfaba2d3babfd...@mail.gmail.com>, > beegee beegee wrote: >> Hi there, I am a beginner in python and I wrote a simple program >> called first.py (using aquamacs) and stored it on my desktop. >> I opened IDLE and wrote the command python first.py >> and I got a syntax error with 'first' being highlighted >> I have a mac os 10.4.11, python 2.6.1 on IDLE >> and I also used the aquamacs compiler for python > > When you are in IDLE, use the Open command from the File menu bar item > to open a python file in a new window.

[Pythonmac-SIG] Building an app with dependencies
Hi all,
I am trying to build a Python Mac OS X application that has quite a
lot of dependencies. We rely on wx, appscript, objc, zope, twisted and
more. Below I provide my setup.py script. I am trying to use py2app
(version py2app-0.3.6-py2.4.egg) as mentionned on the page
http://svn.pythonmac.org/py2app/py2app/trunk/doc/index.html#uninstalling-py2app-0-2-x-or-earlier
.
When I try to build it I get the following error : "running py2app
"""
Traceback (most recent call last):

below is my complete setup.py script.
Anyone has an idea on why i get this ? Is one of my arguments of a bad type ?
Also, is there an alternative to listing the whole list of packages
and modules to be included in the app?
I am using Tiger, but I would like this to work also on Leopard, if possible.
Thanks !!
