OS X leopard installation clarification
by Stephen Uhlhorn Feb. 7, 2008

Feb. 7, 2008

Sorry, but I've been off the list for a couple of weeks, and I'm just trying to catch up on the mac os leopard status... If I understand this correctly: http://ipython.scipy.org/moin/InstallationOSXLeopard , I should stick with the system python and update readline, rather than maintain a separate python.org python, correct? But according to the notes at the bottom of the page, it sounds like if I update numpy, I could bust some system apps. I don't use pyobjc, but I work with numpy/scipy/matplotlib and like to keep these packages up to date. I worry about a new numpy breaking stuff. If I use the system python, will setuptools allow me to keep numpy up to date, without overt breakage? Thanks- -stephen

tkinter shows chinese instead of arabic, os x
by Max Guat Feb. 6, 2008

Feb. 6, 2008

hello, my little lexicon-programm shows chinese (??) glyphs instead of arabic glyphs (tkinter, sqlite, python 2.5, os x - leopard). Especially, this appears in list- and entry-widgets; buttons are (rather) ok. File enconding, output to console is ok. Confusing enough, the same script works fine with Windows. any ideas? Thank you very much max guat Here are a description and screenshots in my blog: http://servuzmaxguat.wordpress.com/2008/01/24/tkinter-macos-und-arabisch/ __________________________________ Ihre erste Baustelle?

Guages, Sliders, Graphs and py2app
by Kenneth miller Feb. 5, 2008

Feb. 5, 2008

All, Couple quick questions here. I've got a small program I'm distributing, all in python, and I'm relying on py2app to distribute it. Which is fine, I can even get it to work with Tk etc. I like Tk, it's simple, but it's too simple for what I want to do. I'd like to be able to display data using widgets like a thermometer, guages (like in your car), orthogonal graphs, polar graphs, etc. Is there a python GUI framework available with these types of widgets that's easy to distribute along with an App built with py2app? Regards, Kenneth Miller

Key Bindings on cross platform apps.
by Christopher Barker Feb. 4, 2008

Feb. 4, 2008

Hi all I'm trying help out Rob McMullen get his "Peppy" editor working well on OS-X. I'm thinking about about key bindings. Apple has the "command" key, but also an "alt"(option) key and a "control" key. I kind of wish they had never introduced a control key, but so be it. Anyway, it seems that for the standard conventions, like cut, copy, paste, save, etc, that Macintosh apps use the "command" key where Windows (and KDE and GNOME) apps use the "control" key. This, for cross platform apps, this is what I think should be done: On the Mac, the default behavior should be for "command" to do everything that "control" does on Windows and Linux, and "control" should do nothing. The alt(option) key should do the same thing as alt on the other platforms. This seems like it makes for the best compatibility. Is this a standard and good way to do it? thanks, -Chris PS: A plug for Peppy: Peppy is yet another text editor written with wxPython. When it first came out, I though "arrggg! why another one?". But it turns out that the author's reasons for another one pretty much exactly match my reasons for never fully adopting any of the others -- they simple weren't designed to be as powerful and flexible as I need to make it my do-everything editor. I've been looking for years for an editor that meets these requirements: - Runs the same way on Linux, Windows, and OS-X - Works well for editing all the kinds of text I need to edit -- with customized modes for all of them (Or the ability to create such modes) - Good python support - Modern UI (all the "standard" keystrokes, etc), and integration with the OS (drag and drop, etc) - Scriptable in Python, so I can add the stuff it doesn't have. - Multiple top-level windows. In a nutshell, I want (X)emacs with a modern UI, and scriptable in python. Rob has set out to build exactly that, and I think he has done an admirable job of creating the kind of flexible, powerful framework that's required to really make it shine. It's still rough around the edges (particularly on the Mac -- I'm his only Mac user right now, and he doesn't have a Mac), but it would be great if some other folks could check it out and help clean up those rough edges. I urge you to give it a try. http://peppy.flipturn.org/ getting the SVN version is probably your best bet. I just added a setup_mac.py file that you can build an alias application bundle with: python setup_mac.py py2app -A I haven't yet tested a full app bundle, but it works pretty well with the Alias mode. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

Nehemiah Dacres wrote: > What is the difference between this editor and editra The big difference is that Peppy has been designed to be more flexible and expendable -- I think it has the potential to be a really great editor for ALL types of text files (and some others -- binary, etc.). Some of the key features: - user-definable key bindings, including emacs style multi-key bindings. - User definable major-modes for different file types. (and I think they are inheritable, so you could create one that was almost like an existing mode, then add/change a bit for your use. - Minor modes -- these are kind of like mix-ins -- extra functionality you can tack onto various major modes -- like word wrapping etc. - You can view the same buffer (file) in multiple windows at the same time. Is does currently lack a bit of polish, particularly on the Mac. Editra (and PyPE, SPE, ulipad, etc....), on the other hand has been built to do what it does well, but without the built-in flexibility. No different modes, no user-definable key bindings, etc. It does work better for the basic stuff out-of-the-box, but I've bumped into limits already with it. In short, the developers have taken a different tack -- Peppy has been designed from the ground up with a focus on getting a flexible (and admittedly complex) framework in place, with some of the usability details on the back burner. Editra, on the other hand, has focused on getting basic functionality in place, including the usability niceties. This does make early version more usable, but I think, in the long run, Peppy has more room to grow. > and is there any > possibility that i would be able to use this via a console? I think there is a possibility in the future that a console mode could be built -- it's got good separation of functionality from UI, but there is only a wx UI at the moment -- I don't think he has plans for a console version. -Chris PS: Peppy is the only editor other than (X)emacs that has a python mode that does indentation right. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception Chris.Barker(a)noaa.gov

Getting cantera to run
by Tavis Feb. 3, 2008

Feb. 3, 2008

Hello, I've been struggling to get cantera to run on my mac. I have OX 10.4.11 with Python 2.5.1 installed and numarray 1.5.2. Importing numarray in python doesn't generate any errors, so I assume it to be working. I ran a Cantera 1.6 binary and it seemed to install ok, but I can't get python to recognize it. I added /Applications/Cantera/bin to my path and I ran the setup_cantera file, though I had to run it line by line in terminal since I couldn't get it to work as a shell script (maybe I should have added .sh to the file? Thats a question for another day). Whenever i try "import cantera" at a python prompt, i get Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named cantera Would I be better off trying to compile cantera 1.7 for the source files? Any other suggestions.

Tuples
by Grzegorz Laszczyk Feb. 3, 2008

Feb. 3, 2008

Hi all :) I have a newbie question. Do you use tuples? If yes, maybe can you explain me where and why. I know, how to use strings, dictionaries, lists. But tulpes? Python is my first language, where I found this. Thanks for explanation.

First time I've seen them all at once. Are there any more? Turns out that /etc/profile actually listened to my request to: export PYTHONPATH='' where the others just ignored it. In addition I found that it was in: > ~/.MacOSX/environment.plist where I had set PYTHONPATH to > /usr/local/Zope-3.3.0/lib/python and then forgot I had done it! Now I have removed that. Anyhow it seems to have done the trick. So many thanks. I will flag your email in case I forget again. George Wright http://users.bigpond.net.au/George.Wright/ http://www.labyrinth.net.au/~gwright
