Good book for learning Python on the Mac
by Pieter Claerhout April 30, 1999

April 30, 1999

Hello, I'm almost brand new to the world of Python. I use Python mainly on the Macintosh, but I can't seem to find a good book explaining how to program in Python on the Macintosh. Most of the stuff I find is either Unix-related of either Win-related. Does anyone has some suggestions for a good book (or a decent website). Thanks, Pieter [ Pieter Claerhout chill(a)mediaport.org ]

Access to Gestalt?

Is there a way to get access to gestalt information in python? The only gestalt related items I could find were a couple of generic system error codes. Erik van Blokland

Samuel, if you'd be willing to take over maintainance of Tkinter on the mac you would make me a very happy person. Tkinter is important, but MacPython is already taking more of my time than I can really afford, and as I don't use Tk regularly I can't really spend time on it at the moment. Everything you need to build it (from the version I used, 8.0) plus instructions are in the distribution, but my attempts to build more recent versions have failed in the short time I allowed myself for it. If you'd be willing to take this up you'd best wait for the next distribution, 1.5.2, due any day now, which has a new structure for plugin modules (which also makes it a lot easier for me to offload modules or module groups to other people, and for other people to distribute their own extension modules). -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

FTPing a mac file - loosing resource fork?
by Chris,Mann April 23, 1999

April 23, 1999

Hello - I've just started using python, and the first thing I'm trying to do is write a little script that retrieves a mac file from an FTP site (it's actually a .sea file). Just when I thought I had everything working, I ran into a bit of a snag. I'm using the provided ftplib and everything seems to work fine, except that the file looses it's resource fork. Any ideas what I'm doing wrong? Here's the code (ftp_site is a dictionary of values that I pass in): def get_remote(self, ftp_site): # open a local file so we have something to write the ftp data to fileID = open(ftp_site['localdir'] + ftp_site['file'] , 'wb') from ftplib import FTP print 'Retrieving ' + ftp_site['file'] + ' to ' + ftp_site['localdir'] # open the site, set pasv transfer mode, and login ftp = FTP(ftp_site['host']) ftp.set_pasv(ftp_site['pasv']) ftp.login(ftp_site['user'], ftp_site['password']) # change to correct dir, check size, and retrieve ftp.cwd(ftp_site['remotedir']) if ftp.size(ftp_site['file']) <= 1000: # know file is always greater then a meg print 'The file appears to be corrupted' ftp.retrbinary('RETR ' + ftp_site['file'], fileID.write, 1024) # cleanup fileID.close() ftp.close() Also, is there a module to decode stuffit compressed files? I had thought about wrapping the stuffit expander OSAX into a module, but that seems a bit roundabout. thanks -chris

Samuel, you should probably also ask your non-mac-specific Tkinter questions in the general Python mailinglist/newsgroup, where you have a much better chance of an answer. I'll stick to answering the mac things I know about: > The python menubar gets replaced with a new menu bar who's menus apparently > do nothing. This is a Tk problem, and I think there's little I can do about it. > I can't quit python once I close a Tkinter window (the Tkinter menu bar > stays on the screen) The only way I could figure out to quit python was to > do a sys.exit(). I bound sys.exit to my Tk quit button but that doesn't > work for the close box on the window title bar. There used to be a workaround for this, which re-installed the Python menubar. Unfortunately it stopped working some time in the past. I'll see whether I can do something about it. > Tk docs refer to a resource file. How is this supported on the Mac.

I'm not familiar with what Tk calls resource files... > I crashed my system a couple of times using Tk with the Mac IDE (Just Van > Rossum's) Is this a serious incompatiblity problem or something that can be > fixed with a little debugging) This is an incompatability that is probably pretty difficult to fix. Both Tk and IDE fight over the eventloop, the menubar, window ownership and a few other things. It shouldn't crash your system, though, at most it should crash Python:-) -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.oratrix.nl/~jack | see http://www.xs4all.nl/~tank/spg-l/sigaction.htm

Tkinter questions

The system crashes when I call .mainloop(). I now can't get v 1.5.1 to work either it looks like it all depends on what menu ID python uses when it boots. If its the same one as Tk I get a crash. Python prints out this MenuID256 is already in use! Fatal Python error: Tcl/Tk panic It looks like the fix has to come in the c code for Tk Sam, ********************************** Samuel M.

I have about 4 years experience programming the Mac toolbox. although it has been a few years since I had done any mac development so I am pretty rusty. If someone can point me in the right direction as to the process of porting Tk to python maybe I can help. It appears that Tk defaults to creating a menu bar etc. There are some issues with the programming model. The python interpreter is an application in its own right. If I run the tk gui should it be its own application or should it live within the interpreters application. >> I can't quit python once I close a Tkinter window (the Tkinter menu bar >> stays on the screen) The only way I could figure out to quit python was to >> do a sys.exit().

I'm not familiar with what Tk calls resource >files... > quote from Prac. Prog. in TCL/TK " The resource database in maintained in main memory by the TK toolkit. On UNIX the database is initialized from the RESOURCE_MANAGER property on the root window or the .Xdefaults file in your home directory. On Windows and Macintosh there are a few resources added by the tk.tcl library file. Additional files can be explicitly loaded with the option readfile command and individual database entries are added with the option add Tcl command. " Basically it enables you to specify attributes for widgets in a resource file instead of hard coded. I would think that this behavior could be replicated using the native macintosh resource fork. I could find no reference to a similar "option readfile" command to get attributes from the resource database. >This is an incompatability that is probably pretty difficult to fix.
