[ann] appscript 0.13.0 posted
by has July 11, 2005

July 11, 2005

Hi all, Just posted new versions of appscript, aem and osaterminology to: http://freespace.virgin.net/hamish.sanderson/appscript_source.html Mostly bug-fixes and minor improvements. If folk'd like to pound on 'em a bit and let me know if there's any problems, it'd be much appreciated. If all's well, we can see about getting some installers knocked out. has -- http://freespace.virgin.net/hamish.sanderson/

Mac OS X volume ownership
by Chinook July 10, 2005

July 10, 2005

I hope this is not too far of the mark for this forum, but I'm having a problem with a point in a maintenance module I'm trying to create. I've started from the bottom here in trying to work things out in a bash script first. The point I'm having a problem with is how to uncheck/unset "Ignore ownership on this volume" as one might with the Get Info pane. I've managed to construct the mount point and device node, but this issue causes me a problem in further access. Anyone know? Thanks, Lee C

Hi, Based on google searches, it seems that rpy (interface for R) should build ok on 10.3.9... how to do it? Is there a binary installer available (compatible with pythonmac.org/packages/)?

In this case, all you need to do is tell it you have this custom class, and an instance of your class is the dataSource for your table. The rest should happen at runtime. --Dethe Thought is an infection. In certain cases it becomes an epidemic. -- Wallace Stevens

Did anyone play with TransformProcessType yet?
by Jack Jansen July 7, 2005

July 7, 2005

No, I've not come out of hiding just yet (still far too busy with Ambulant to do any Python work), but I came across TransformProcessType just tonight, so I did a quick experiment and it seems to work. What it does is turn any process into a full-fledged windowing application, with a dock icon, the possibility of a menu bar, etc. So this may be the way to get rid of "pythonw". I quickly added a method MacOS.SetWMAvailable(), and it seems good enough for running the IDE with "python" in stead of "pythonw". The icon is ugly (a terminal- style script), and the application menu title is "python" in stead of whatever script you're running, but that can all be fixed. Did anyone else have a look at this call? Is it worth it to invest some time into it? If it is I'll check it in and people who build Python from CVS can play around with it. Please reply also to me personally, I still have 847 pythonmac-sig mails waiting for me so if you reply only to the list it'll be a long time before I see it... -- Jack Jansen, <Jack.Jansen(a)cwi.nl>, http://www.cwi.nl/~jack If I can't dance I don't want to be part of your revolution -- Emma Goldman

Re: [Pythonmac-SIG] Discussion of Python IDE's: strengths andweaknesses (long)
by Henning.Ramm＠mediapro-gmbh.de July 7, 2005

July 7, 2005

Thank you very much for this overview! I tried several IDEs about a month ago to find the suiting one for my little projects and made partly the same, partly different experiences. Several apps showed the same problem on my german Tiger: The text in interpreter windows is not readable (only top part of characters is shown); if I had an option to enable antialiasing, it showed up, but not every app provided that. (Perhaps an issue with some system preference?) Another common problem is non-working (or even crashing) drag-and-drop of files to the IDE's windows or dock icon. Several IDE's I didn't get to use Python 2.4.1 (and the new wxPython), AFAIR it was Boa and PyOxide. And I don't like how most Python editors (even if they use Scintilla) handle (or mostly not-handle) non-Python files - be it config, HTML, text or other-language files. >2. Spe, which also includes wxGlade and other tools. I like SPE on WinXP, even if it tends to run into exceptions after that you seem to be able to work, but you can't save anymore - very dangerous! Other non-options like printing behave the same. On OSX I don't like how SPE's windows are split (notebook tabs, but separate windows, focus change doesn't really work). There were a lot of development for a while, but lately Stani stays quiet - perhaps he choked on his debugger-integration plans. >3. Eric3 Again I didn't manage to let it use Python 2.4.1 Strangely the app starts only every second time. Some more: 7. Eclipse is a mighty Java IDE, or more an application framework that ships with a Java IDE, but there are also two or three Python modules (PyDev, TruStudio). Eclipse's interface has nothing to do with any OS's standards, but I think one will get used to it. But at least on my G4/400 it's just too slow (esp. startup), and I can't wrap my mind around it's concepts. Perhaps that's why I got lost in the preferences and didn't find source browser, code completion etc. 8. DrPython a rather nice little light-weight (wx)Python IDE, extensible with plugins (i.e. a lot of important features are outsourced to plugins), but most plugins are outdated, have bugs or don't work for other reasons. I think it would be suited to replace IDLE more than most other candidates, but needs a bit of work for all the nice features to actually work. There's no Mac bundle yet, you must run it from Terminal. Best regards, Henning Hraban Ramm Südkurier Medienhaus / MediaPro Support/Admin/Development Dept.

ANN: Boa Constructor for OS X available
by Kevin Walzer July 7, 2005

July 7, 2005

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Boa Constructor is now available for Mac OS X. Boa is a cross-platform Python IDE and wxPython GUI Builder. It offers visual frame creation and manipulation, an object inspector, many views on the source like object browsers, inheritance hierarchies, doc string generated html documentation, an advanced debugger and integrated help. This is the first version of Boa Constructor (O.4.3) to be distributed as a Mac-native application. Boa Constructor requires the installation of MacPython 2.4.1, wxPython 2.6.1, and Mac OS X 10.4. It is extremely unstable on earlier versions of Python/wxPython and has not been tested on an earlier version of Mac OS X. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (Darwin) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFCskxiJmdQs+6YVcoRAmXHAJ43146ihx3YewreeGtrLz5US/jnZwCfUHf4 rr+88Q+W3Uvb0kWVLXxVFE4= =Xc0/ -----END PGP SIGNATURE-----
