Re: [PYTHONMAC-SIG] regarding sys.path (was: Anyone using $(APPLICATION) in sys.path preferences?)

Recently, "jeffrey P. Shell" <jeff(a)cynapses.com> said: > [on losing parts of sys.path set through EditPythonPrefs] > > i can append stuff to sys.path from a script or from the interpreter, > but after a certain point i can't add any more inside EditPythonPrefs Found it! It turns out that SetDialogItemText() cannot handle more than 255 chars, which is to be expected but which I forgot. The workaround, for now: if you need more than 255 chars in your sys.path initializer use ResEdit to edit "Python 1.4 Preferences" by hand, and modify the STR# resource. For the future I will implement a different EditPythonPrefs. Some time ago Just sent me a first stab at a much nicer EditPythonPrefs, and I also want to make the functionality available to python programs anyway so this is probably the moment to do the rewrite. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)cwi.nl | ++++ if you agree copy these lines to your sig ++++ http://www.cwi.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm ================= PYTHONMAC-SIG - SIG on Python for the Apple Macintosh send messages to: pythonmac-sig(a)python.org administrivia to: pythonmac-sig-request(a)python.org =================

Application Running?

I need to be able to test if an application that I launched with findertools.launch(file) is still running. Can anyone tell me how to do that in Python?

Python archive generator
by Jurjen N.E. Bos March 28, 1997

March 28, 1997

The following Mac Python program can generate archives of text files (for example, Python code :-) The archive generates spaces for the tabs (3 spaces for a tab), produces proper escape sequences for quotes and backslashes, and warns you for lines longer than 72 chars (that may break on some mailers). The archive can be unpacked simply by running it through any (not necessarily Mac) python. The produced archives will be checked using MD5, if the unpacking computer has it available. In any case, the length is checked. Usage: - run the script - choose the readme files, and all other files using the dialog boxes - when all files are done, give "Cancel" - choose the place to store the archive using the dialog box (For the transmission, I let it pack itself, of course :-) #! /usr/local/bin/python # This is a Python archive; run through your Python to convert. # Supports bit error detection using MD5 (if available). # For human readers: # - File beginnings can be recognized by a "scissors": ----8<---- # - Files begin and end with a triple quote ('''). # - Backslashes and triple quotes are preceded by a backslash. # Generator written by Jurjen N.E.

Alpha (editor) Python mode help
by Dave Wyble March 14, 1997

March 14, 1997

Greetings, I am currently using Alpha, which seems to be a very nice product. My only problem is that I don't know Tcl at all and I am having some difficulty coming up with a good mode file for python file. If anyone has done this and is willing to share it I would really appreciate the help. If you can get yourself to Rochester I'll even consider buying dinner ;) I suppose I would entertain suggestions about other (free or cheap) programmer's editors customizable for python. Let's keep this nice though, I don't want to be responsible for starting a religious war! Thanks. Dave David R.

Using Stuffit Expander on the tar.gz file, the Mac project file seq.hqx is corrupted -- probably has the wrong EOLs -- and it crashes my Mac trying to unstuff it. Using Mac gzip & Mac tar, I am able to unbin hex and extract the project files, but the .ps.gz files in the Doc directory are corrupt ( probably from the Unix->Mac EOL translation done to fix the first problem. Looks like you've got to do a double unstuff to get it ALL properly translated. [ David -- you might consider using Stuffit or something Mac native for the final finished release! ] ---| Steven D.

If someone is going to have a look at this Mac port of SWIG: please let me know. I'd love to look into it but I don't have the time:-( Something that would be pretty handy would be if it could spit out modules in calldll style, since this would allow people without development environment and without intricate knowledge of universal headers to create interfaces to arbitrary C routines. Modifying bgen to do something similar is still on my list, but it remains to be seen when I have the time to do this... -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)cwi.nl | ++++ if you agree copy these lines to your sig ++++ http://www.cwi.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm _______________ PYTHONMAC-SIG - SIG on Python for the Apple Macintosh send messages to: pythonmac-sig(a)python.org administrivia to: pythonmac-sig-request(a)python.org _______________
