Packaging Imagemagick into wxPython standalones.
by Jeremy Gibbs Oct. 15, 2007

Oct. 15, 2007

I am creating a very simple front end to a vector graphics package that one of my professors wrote. His package writes the images out in .eps format. So in my code I just call ImageMagick's 'convert' function to jpeg. From jpeg I can use wxPython's ConvertToBitmap() feature to display the image to the user. This works great from the command line, but when I try to make a standalone with py2app, it fails due to 'convert' not working. When this didn't work, I tried using PIL and converting by Image.open and Image.save. Again, this worked great from the command line, but failed in the standalone version. I suspect it is likely that I am not including all relevant libraries needed for this to work. Has anyone had any experience using ImageMagick or PIL in a standalone application to convert image types? Thanks for any help. Jeremy Gibbs

Audio_mac.py fails in writeframes
by punch Oct. 11, 2007

Oct. 11, 2007

I'm running 'OS X' 10.4.10 and python 2.5.1 on a MacBook Pro SR. When I try to run any of the audio demos, specifically Audio_mac.py, I get errors. The error is in the writeframes method. It appears to try and pack the constant extSH (set to 0xFF) as a signed byte, which it cannot do. I've searched all around and found one guy on the net with this problem but no answer. I can over-ride the writeframes method but what should extSH be? Any help appreciated. -- >>>bill<<<

py2app: Leopard vs. Tiger
by Kevin Walzer Oct. 10, 2007

Oct. 10, 2007

I'm debating when to move my own development machine to Leopard. Right now all the components that I use to assemble my Python app were built on 10.4, so I know they should run on both 10.4 and 10.5; I want to continue to support 10.4. However, will an application that is bundled by py2app on 10.5 run on 10.4 if all the frameworks were originally build on 10.4? Does py2app introduce any kind of additional compilation that would break backward OS compatability? -- Kevin Walzer Code by Kevin http://www.codebykevin.com

easygui
by Rafael Bejarano Oct. 6, 2007

Oct. 6, 2007

Hello, I just subscribed to this list, so please allow me to introduce myself. Although I am a long-time Mac user, I just recently started learning python. My primary interest in python is as a way to create simple programs with which to run psychological experiments (I am an experimental psychologist). This means that I need to be able to create simple GUIs to collect behavioral measures from research participants, such as response times (how long it takes them to respond to a stimulus after appears on the screen). Given this, I was delighted to discover easygui, a module for creating simple GUIs. When I tried to run it following the instructions that I downloaded from the python website, however, I couldn't get it to work on my iBook g4. I did not get an error message, but no buttons or dialog boxes appeared, either. Can anyone on this list tell me if easygui works on the Mac, and if so, what steps I need to take to make it work? Your assistance with this problem would be grately appreciated. Cordially, Rafael Bejarano

python program in menu bar

Can anyone point to a simple example of a python program that runs in the menu bar? I'd like a program that just displays a few characters of text in the menu bar, and updates the display once a minute or so. Thanks, Dan

Re: [Pythonmac-SIG] Pythonmac-SIG Digest, Vol 54, Issue 7

Rafael, You might also want to consider using Applescript Studio and then making "do shell script" calls to python. This is quite effective for simple dialog boxes. I have made a few of these applications and they have a huge bang for the buck. Noah

entire applications in python?
by Brett Calcott Oct. 4, 2007

Oct. 4, 2007

Hi, I've recently moved to the mac from windows (some experience on unix/linux too). I programmed a lot in C++ and a fair amount python. I much prefer coding in python these days. I've written a lot of user interface code (MFC/wxWindows/wxPython), and I'd like to get up to speed to writing some presentable applications on the mac using the native tools. I was wondering how best to make a start. A few questions (but any hints would be good) Do any of the experienced mac developers out there recommend doing everything in python? Or should I dabble with objective-c applications first? I've seen the pyobjc examples, but are the people out there writing complete applications just using python? Are there any open source examples? Is there "the book" for learning the basics of the mac system? Likewise, is there a book on objective-c for experienced programmers? Thanks in advance, Brett -- Brett Calcott Philosophy Program, Research School of Social Sciences, AND Centre for Macroevolution & Macroecology, School of Botany & Zoology, AUSTRALIAN NATIONAL UNIVERSITY, Canberra, ACT, 0200, AUSTRALIA

was : py2app: how to include the entire standard library of modules?

(If anyone knows of an easier way to do this, let me know.) Make the following changes to setup.py: includes = [] OPTIONS = {'argv_emulation': True, 'plist':plist, 'includes':includes, Next you will run the following script in the same folder as your setup.py. Put the names of the packages you don't want included in the skip list. #Collects all standard modules with paths and inserts them into the config file #for py2app. import os import os.path import sys path = '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5' modules = [] skip = ['site-packages', 'lib-tk', 'test', 'idlelib'] for root, dirs, files in os.walk(path): for item in skip: if item in dirs: dirs.remove(item) for f in files: d = root.replace(path, '') full_path = os.path.join(d, f) if '\\' in full_path: full_path = full_path.replace('\\', '.') if '/' in full_path: full_path = full_path.replace('/', '.') if full_path[0] == '.': full_path = full_path[1:] if full_path.startswith('plat-mac.'): full_path = full_path[9:] if full_path.startswith('lib-scriptpackages.'): full_path = full_path[18:] if full_path.startswith('plat-darwin.'): full_path = full_path[11:] if full_path.startswith('.'): continue #Ignore .pyc and .pyo files if f.endswith('.py') \ and not f.startswith('_'): full_path = full_path[:-3] #Save each part of the file path as part of the module name: #foo.foo1.foo2.py has a package foo, a sub-package foo1, #and a module foo2.
