Temp files/dir
by Robin Siebler Sept. 13, 2002

Sept. 13, 2002

I guess I didn't word this very well. What I was trying to find out was *where* to place temp files, which is very easy to find out in Windows. After pounding my head against the monitor and searching Google for about 30 minutes, I finally found this AppleScript command "path to temporary items folder", which seems to be what I wanted to know. Thanks for the help though. Aside from a post to this group, I never found anything that said how to find the startup disk on a Mac. Robin L.

Types and casting

Hi All, I am reading in raw image files from a frame grabber for processing. What I really want is a matrix of integers for analysis (I don't care about the image itself). Is there an easy way to get python to do this?

Check your PATH variable. I noticed that /usr/local/bin is no longer in the default path, and that's probably where you installed your framework python and pythonw.

Too bad. Maybe > they'll learn to understand open source development eventually. Actually, they did get into touch with me (albeit at a late stage) and I suggested they stay away from the framework build for now. Not that it mattered any what I said, as things were underway too long anyway (I did try to get 2.2.1 in stead of 2.2 included, but even that wasn't possible anymore). The 2.2.1 framework build has too few advantages over the non-framework build (and the 2.2 framework build was basically non-functional). Moreover, there are potential problems with it (for instance the crash if you import a Carbon or other windowing module if you don't have access to the window server). What I think we should do is go full speed ahead with a decent framework build for Python 2.3, and make sure that such a build can coexist with Apple's non-framework 2.2 with as little confusion to the user as possible. If Apple stick to the 9 month release cycle that seems to be appearing then Python 2.3 will probably miss the window for MacOSX 10.3 anyway. But if PythonLauncher and the IDE and such tools are aware of the fact that there are probably two distinct Python installations there really isn't much of a problem. And it gives us the freedom to do development in our own time, in stead of being tied to someone else's release schedule. (Incidentally, this de-coupling of release schedules is also why I'm hammering on this Python Install Manager stuff over on pythonmac-sig: with wxPython and PyObjC and such seeing so much activity at the moment it would be a real shame if new versions would become available to the general public only when a full Python release is done. If the PIM can make it relatively painless to install and upgrade packages we can have our cake and eat it too. -- - Jack Jansen <Jack.Jansen(a)oratrix.com> http://www.cwi.nl/~jack - - If I can't dance I don't want to be part of your revolution -- Emma Goldman -

Need help with AppleEvent bug
by Jack Jansen Sept. 12, 2002

Sept. 12, 2002

Folks, I need help from some AppleScript gurus. Robin Siebler posted bug http://www.python.org/sf/598981 which has to do with a get() call to CodeWarrior to get the data of the frontmost window returning None. Bill Fancher suggested that this might have to do with Python not supporting the cText AppleScript type, but that would have shown up differently: you would have gotten a return value, but of type aetypes.Unknown('ctxt', 'raw data'). I ran the thing under the debugger, and it turns out the reply AppleEvent from AESend() indeed doesn't have a '----' parameter, and it doesn't have an 'errn' error code either. So, returning None is the right thing to do. But the corresponding AppleScript works fine... Now I very vaguely remember something about there being a second protocol for sending replies to AppleEvents (maybe for long replies >= 32K? I don't remember... And maybe I'm completely confused with something else, like the funny CGI protocol with AppleScript) but I can't find anything after looking through the documentation. So, to sum it up, I'm out of my water and need a bit of help. The bug report has everything you need to reproduce this. -- - Jack Jansen <Jack.Jansen(a)oratrix.com> http://www.cwi.nl/~jack - - If I can't dance I don't want to be part of your revolution -- Emma Goldman -

Python that ships with Jaguar vs...
by christopher ariza Sept. 12, 2002

Sept. 12, 2002

while we are on the issue of the jaguar python, it seems that xml.dom.minidom is broken in the python that apple ships: [GCC Apple cpp-precomp 6.14] on darwin Type "help", "copyright", "credits" or "license" for more information. >>> import xml.dom.minidom >>> doc = xml.dom.minidom.parseString("<doc>my document.</doc>") Traceback (most recent call last): File "<stdin>", line 1, in ? File "/BinaryCache/python/python-3.root~193/usr/lib/python2.2/xml/dom/ minidom.py", line 965, in parseString File "/BinaryCache/python/python-3.root~193/usr/lib/python2.2/xml/dom/ minidom.py", line 951, in _doparse File "/BinaryCache/python/python-3.root~193/usr/lib/python2.2/xml/dom/ pulldom.py", line 340, in parseString File "/BinaryCache/python/python-3.root~193/usr/lib/python2.2/xml/sax/ __init__.py", line 93, in make_parser xml.sax._exceptions.SAXReaderNotAvailable: No parsers found >>> can somebody with 10.2 test this for me? what is this /BinaryCache? i dont have 10.2 yet so i have this information from someone else. eitherway, i was under the impression that xml.dom.minidom was standard python: this works in win, MacPython, and macho-python. can anyone tell me why it would not work in what is supposed to be a 'standard' unix build? many thanks. ____________________ christopher ariza http://flexatone.com

Programming Problem: comparing files with "known" differences
by Robin Siebler Sept. 11, 2002

Sept. 11, 2002

I am trying to perform the following task (in an automated fashion): 1. Launch CodeWarrior and disassemble a file 2. Compare the output from this with a "known" file. Now, the first 4-5 lines of each file are always going to be different, but after that, they should always be the same. My current script uses AppleScript to launch CodeWarrior, disassemble the file and grab the output. I then pass the output to Python (as a list of strings), strip the first couple of lines from the output and the "known" file and compare the two. However, the output contains a backslash in places and somehow when I pass the output to Python it gets replaced with double backslashes, which causes the compare to fail. I have 2 questions: 1. Is there a better way to do this? a) I tried to save the output file from CodeWarrior using AppleScript (which would alleviate the problem), but giving CodeWarrior a save command brought up a Save dialog which I don't know how to deal with (I have minimal AppleScript experience). b) I looked at the man page for diff, but I couldn't see a way to have diff compare only the lines which should be the same (I have minimal *nix experience) 2. Is there a way to get rid of the double backslashes? I tried string.replace("\\", "\") but I get a syntax error. I have attached the scripts if anyone cares to look at them. <<cw_handler.py>> <<disassemble_files.py>> Robin L.
