CoreGraphics and Python and Panther
by Gus Mueller Oct. 25, 2003

Oct. 25, 2003

I just wanted to say that wow, the CoreGraphics module in 10.3's python is awesome. Very neat, and I'm sure we're going to see some really cool stuff come out of it. Making pdf's has never been so easy. #!/usr/bin/python import os from CoreGraphics import * from urllib2 import * html = urlopen("http://www.python.org/").read() pageRect = CGRectMake(0, 0, 612, 792) ctx = CGPDFContextCreateWithFilename("python.pdf", pageRect) ctx.beginPage(pageRect) ctx.drawHTMLTextInRect(CGDataProviderCreateWithString(html), pageRect) ctx.endPage() ctx.finish() os.popen("/usr/bin/open -a Preview python.pdf") If whomever is responsible for this at Apple is listening- thanks! -gus -- August Mueller http://flyingmeat.com/ VoodooPad - 1st Place U.S., O'Reilly Mac OS X Innovators Contest round 2 "Christmas means carnage!" -- Ferdinand, the duck

Xcode + Python (pythonmac.org wiki)
by Bob Ippolito Oct. 25, 2003

Oct. 25, 2003

I've started an entry in the pythonmac.org wiki about Xcode + Python integration ( http://pythonmac.org/wiki/XcodeIntegration ). There's hardly anything there yet, right now just a replacement for the example StartupScript, but I plan on tinkering with Xcode this weekend and will be adding user scripts and/or plugins for stuff like pydoc integration. -bob

Yes, there is a sh-bang at the top of the script: #!/usr/local/bin/python The script runs if I comment the statement "from name_of_library import special_function" out (except the error because of the missing functions which are in the library ;) ). The Apache-Config is set to allow cgis to execute in that directory. <Directory "/Users/projectname/Sites/"> Options Indexes ExecCGI MultiViews AllowOverride None Order allow,deny Allow from all </Directory> Am Freitag, 24.10.03 um 05:20 Uhr schrieb Sarwat Khan: > Do you have a sh-bang at the top of your script?

Where's EditPythonPrefs ??
by Louis M. Pecora Oct. 24, 2003

Oct. 24, 2003

I finally made the change to OS X and downloaded and installed MacPython-2.3. But... I cannot find EditPythonPrefs. The documentation and help tell me to use it to add the path to my modules, but the only copies I have are old system 9 ones. Nothing like EditPythonPrefs seems to be in the new MacPython 2.3. Am I missing something. I've spent some time going through the help files, but I can't find a clue. Can anyone point me to how to add paths to modules with 2.3? Thanks for any help. -- Cheers, Lou Pecora

by helloleo Oct. 23, 2003

Oct. 23, 2003

hi there one silly question at the beginning: how can i extend the python search paths? i guess i need that for installing aeve for apple event handling, because right now i get an error when i run setup: Traceback (most recent call last): File "/Users/leo/dev/python/aeve-0.0.3/setup.py", line 5, in ? import aeve File "/Users/leo/dev/python/aeve-0.0.3/aeve/__init__.py", line 30, in ? import aetypes File "/Users/leo/dev/python/aeve-0.0.3/aeve/aetypes/__init__.py", line 5, in ? from aeclass import * File "/Users/leo/dev/python/aeve-0.0.3/aeve/aetypes/aeclass.py", line 1, in ? from aecomplex import BaseClass File "/Users/leo/dev/python/aeve-0.0.3/aeve/aetypes/aecomplex.py", line 4, in ? from aesimple import Type, Enum, FourCharCode, AbsoluteOrdinal File "/Users/leo/dev/python/aeve-0.0.3/aeve/aetypes/aesimple.py", line 8, in ? import TECManager as TE ImportError: No module named TECManager any idea? thanks, leo

How to import libraries on Mac OS X?
by Eric Wichterich Oct. 23, 2003

Oct. 23, 2003

Hello Pythonistas, I've written a Python library with some functions I want to use with other Python scripts. The library is located at (Mac OS X): /Users/username/Sites/projectname/cgi-bin/name_of_library.py (My scripts are located in this directory, too.) I use the statement: "from name_of_library import special_function" to import this special_function. When I launch the Apache-Server and call a script which wants to import this library, I get a "malformed header" error. But importing standard libraries, such as "from string import *", no error occurs. Maybe some environment variables must be set. But which? Any ideas? Thank you, Eric

MatFunc.py
by Chris Lee Oct. 22, 2003

Oct. 22, 2003

Hi All, The other day I was searching for a curve fitting module (It turns out that our Matlab license doesn't cover the curve fitting toolbox). I found a module Matfunc.py but the urls leading to the actual module are broken. I was wondering if anyone has installed it or can send me a copy?

[ANN] New PPlot release with python/ruby wrapping
by Drew McCormack Oct. 21, 2003

Oct. 21, 2003

A new release of the plotting framework PPlot has just been made (http://pplot.sourceforge.net/). This release includes python and ruby wrapping code, so that you can create plots with scripts embedded in your applications. There is a simple Cocoa application example given that allows you to display plots by entering python scripts into a text view. PPlot is a lightweight framework written in C++, and designed to be platform and API independent. You can build using Qt or Cocoa for the Mac. The Cocoa version uses Cocoa native drawing, so you get all the benefits of Quartz. You can use C++ or Obj-C++ to create plots, of course, but if you use a bridge like PyObjC (http://pyobjc.sourceforge.net/) or RubyCocoa (http://www.imasy.or.jp/~hisa/mac/rubycocoa/index.en.html), you can now program directly in Python or Ruby in your Cocoa apps. Even without these bridges, you can run python and ruby scripts to generate plots from within a Cocoa app. Download: https://sourceforge.net/project/ showfiles.php?group_id=66291&release_id=188905 Drew McCormack ---------------------------------- Dr. Drew McCormack Trade Strategist (www.trade-strategist.com) Stock Market strategy design platform for Mac OS X.

thread blocking problem?
by William McLendon Oct. 21, 2003

Oct. 21, 2003

This has me quite perplexed. I'm trying to make a little app that uses a basic http server that can launch a series of scripts and still run while the scripts are running. I'm attaching 2 source files that can replicate what's happening in my bigger script: I put these two files (myhttpd.py, execute.py) in one directory and run myhttpd.py. Load http://127.0.0.1:2000/ in a browser and hit the execute button. This should then kick off execute.py in a different thread? I've used a variety of different commands to run it (spawnv in this example) but the result is the same. The big problem is that the main thread running the http server seems to block till after execute.py is done. What is causing the blocking here? you can watch the progress of execute.py by doing tail -f out.txt in another window... the blocking should show up then. I've even tried making execute.py daemonize itself but the blocking still happens. #!/usr/bin/env python2.2 # myhttpd.py import os import time import BaseHTTPServer class httpRequestHandler(BaseHTTPServer.BaseHTTPRequestHandler): server_version='test/1.0' def do_POST(self): if self.path=='/execute': self.send_response(200,'OK') self.end_headers() self.wfile.write("<html><head></head><body>\n" self.wfile.write("<h1>done</h1></body></html>\n") pid = os.fork() if pid == 0: os.spawnv(os.P_NOWAIT,'execute.py', ['']) os._exit(0) def do_GET(self): if self.path=='/': self.send_response(200,'OK') self.end_headers() self.wfile.write('<html><head></head><body>\n') self.wfile.write('<form name=execute method=post ') self.wfile.write('action="http://127.0.0.1:2000/execute">\n') self.wfile.write(' <input type="submit" name="execute" value="execute">\n') self.wfile.write('</form></body></html>\n') if __name__ == '__main__': server = BaseHTTPServer.HTTPServer(('127.0.0.1',2000), httpRequestHandler) while 1: server.handle_request() #!/usr/bin/env python # execute.py import os import time ofp = open('out.txt','a') n = 10 for i in range(n): time.sleep(3) ofp.write((n-i+1)*' ') ofp.write((2*i+1)*'.'+'\n') ofp.flush() for i in range(2): ofp.write((n)*' ') ofp.write('...\n') ofp.flush() ofp.close() I'm running this with python 2.2 on OS X 10.2.6 -- any help to get this to execute without blocking would be greatly appreciated.
