Simple AppleScript Class
by Jay Painter Sept. 10, 1998

Sept. 10, 1998

I've written a very simple convinence class for writing AppleScript with the OSAm module. I'm sure it could be better, but here's the class and a quick example. Suggestions are greatly appreshated... class AppleScript: def __init__(self, *args): self.script_list = [] for i in range(len(args)): self.script_list.append(args[i]) def Append(self, *args): for i in range(len(args)): self.script_list.append(args[i]) def AppendScript(self, applescript): self.script_list = self.script_list + applescript.script_list def Clear(self): self.script_list = [] def Text(self): return string.join(self.script_list, '\n') + '\n' def CompileAndExecute(self): import OSAm return OSAm.CompileAndExecute(string.join(self.script_list, '\r')) def CompileAndSave(self, path): import OSAm return OSAm.CompileAndSave(string.join(self.script_list, '\r'),path) Examples... script = AppleScript( 'tell application "Finder"', ' empty trash', 'end tell' ) script.CompileAndExecute() # executes it script.CompileAndSave(os.path.join(os.getcwd(), 'trashscript')) ... emptys the trash. I've had problems with the ExecuteCompiledScript method in OSAm that I'm trying to fix, so I have to use a small script to launch the saved applescript from above: launch_script = AppleScript( 'set scriptobj to (load script file "%s")' % (os.path.join(os.getcwd(), 'trashscript')), 'tell scriptobj', ' run', 'end tell' ) launch_script.CompileAndExecute() # runs the saved/compiled applescript This should probably be part of the applescript class, but I'm hoping to get RunCompiledScript working in OSAm so I don't have to do this anymore. ----------------------------------------------------------------------- Jay Painter -- jpaint(a)serv.net -- jpaint(a)gimp.org -- jpaint(a)real.com http://www.serv.net/~jpaint

Packages
by Rob Managan Aug. 25, 1998

Aug. 25, 1998

I am working a little on getting the openGL extension working on the mac with the latest Mesa libraries. One question that comes up is how to work with packages. Do all the directories involved have to be added to sys.path? In testing this package I get from OpenGL.GL import * ImportError: No module named OpenGL.GL I have added PyOpenGL-1.5.3:OpenGL and PyOpenGL-1.5.3:OpenGL:GL to the path. I get the same message whether the second is added or not. So I guess I am asking whether packages work in the Mac version! Are there any others out there to test? *-*-*-*-*-*-*-*-*-*-**-*-*-*-*-*-*-*-*-*-*- Rob Managan mailto://managan@llnl.gov LLNL ph: 925-423-0903 P.O.

Python on the Mac

Hi Rob, Do you have the official OpenGL implementation from Connix to test it against? If not I'd try emailing them and asking for a demo version - they're very obliging.

Re: [Pythonmac-SIG] ftplib.storbinary problem
by Doug Wyatt Aug. 24, 1998

Aug. 24, 1998

Hmn, the fix didn't completely solve the problem; I tried a larger file and its size on the server was too small, and not a multiple of the block size, as if the last block was not completely sent before the connection closed. I'd appreciate any help. Doug ~~~~~~~~~~~~~~~~ Hi all, Here's another problem that has come up in my switch from Python 1.5a2 to 1.5.1. I'm using ftplib.storbinary to transfer a file to a server. I'm using a 16K blocksize. The file I'm transferring is 364494 bytes in size, but the server is only receiving 360448 bytes. 360448 is a multiple of 16K. I tweaked ftplib.storbinary to show its progress... def storbinary(self, cmd, fp, blocksize): '''Store a file in binary mode.''' self.voidcmd('TYPE I') conn = self.transfercmd(cmd) totalSize = 0 while 1: buf = fp.read(blocksize) if not buf: break conn.send(buf) l = len(buf) totalSize = totalSize + l print l conn.close() print 'totalSize=',totalSize return self.voidresp() It looks like conn.send() might now be asynchronous and thus conn.close() is getting called before the transfer is complete? I don't know how else to explain this. [10 minutes later] Indeed, yes, if I change it to: conn.send(buf, socket.MSG_WAITALL) # WAITALL - dsw it works!!! Am I reporting this to the right place?

BBEdit language support?

Howdy all! I'm wondering, has anyone put together a module for BBEdit that supports syntax highlighting and function drop down functionality? Seems like that would certainly improve my day to day work. :) --p ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Patrick Curtain, Husband & Father (I also write Software) patrick(a)swdev.com, http://www.swdev.com/

Graphing capablility in Mac Python
by Anthony M. Ingraldi Aug. 23, 1998

Aug. 23, 1998

Hello, Is there a module available that will provide routines for creating simple line graphs and scatter plots? I was thinking of using AppleEvents to send data to KaleidaGraph or some other package but that seems sluggish. Another alternative would be to use a Canvas widget from Tk. I would prefer to use a module designed specifically for plotting rather than writing one via Tkinter. -- Tony Ingraldi | e-mail: A.M.INGRALDI(a)LaRC.NASA.GOV NASA Langley Research Center | Mail Stop 267 | Phone : (757) 864-3039 Hampton, VA 23681-0001 | Fax : (757) 864-7892 _______________ 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 _______________

Python CGI server
by Just van Rossum Aug. 20, 1998

Aug. 20, 1998

My friend Erik retrieved the old CGI Python server I mentioned yesterday. I added some comments and changed a few things without testing it. I don't know much about CGI, let alone CGI on the Mac, so if this thing appears simple-minded: well, it is. If you can use it, please do, if you make any improvements, please let me know. If it works well enough, maybe we should put it in the cgi demo folder in the next distribution. Poissibly this script could be expanded so it puts the arguments/parameters from the http request in the proper places, so they are accessible from the CGI module. Then *maybe* unix CGI's could "just work" on the Mac. Let me know if you have any ideas about this. Just --- pythoncgislave.py --- """pythoncgislave - A minimal Python server for CGI scripts.""" import MacOS # It seems sometimes AE's get lost if we don't do this. # Not sure if this is still true. MacOS.EnableAppswitch(-1) import os import string import StringIO import sys import traceback __version__ = '2.1' # fiddle with the next bit so _root becomes the root http directory # I guess that if this applet lives in the http root directory # it would be enough to write: # _root = os.path.dirname(sys.argv[0]) _thisapplethome = os.getcwd() _root = os.path.dirname(_thisapplethome) from MiniAEFrame import AEServer, MiniApplication class CGIslave(AEServer, MiniApplication): def __init__(self): MiniApplication.__init__(self) AEServer.__init__(self) self.installaehandler('aevt', 'oapp', self.open_app) self.installaehandler('aevt', 'quit', self.quit) self.installaehandler('WWW\275', 'sdoc', self.cgihandler) print 'ready.' print "python cgislave " + __version__ # dict for some semi-persistent things. self.lib = {} def quit(self, **args): self.quitting = 1 def open_app(self, **args): pass def cgihandler(self, pathargs, **args): path = args['scnm'] # convert unix path to mac path, prepend http root dir. path = string.join(string.split(path, '/'), ':') path = os.path.join(_root, path) # Reroute stdout and stderr.

Mac web servers for Python CGI
by Patrick Curtain Aug. 19, 1998

Aug. 19, 1998

Howdy All! I'm checking into what web server might work best at integrating Python as a CGI tool. What's everyone else using? AppleShare IP looks promising. NetPresenz looks solid (and gets a mention in the MacPython CGI info), but also looks out of date.

Re: [Pythonmac-SIG] Python for MPW?

Python ran under MPW many many years ago, but it hasn't been tried in ages. I you do try to build it I would be interested in the results. There are #ifdef MPW sprinkled through the code, but (1) definitely not in all places they're needed, (2) they're both for compiler dependencies (and I assume you'll be using the MW compilers, not the old Apple compilers) and for runtime dependencies and (3) the code inside the MPW ifdefs hasn't been looked at for ages. I think the best starting place would be the PythonStandSmall project, which builds a "minimal useful" Python. You may have to get rid of GUSI (not sure whether that works under MPW) and you'll probably have to compile with MPW newlines. It would probably also be a good idea to immedeately change the version string (an STR in one of the resource files, I think pythonpath.rsrc), as you want a different preferences file for sys.path initialisation because you can't share dynamic modules (and, if you use MPW newlines, not even .py files either). I think the project would definitely be doable, but not trivial. -- 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
