Another question:  is there a way I can make an LED on my MacBook Pro
flash?  My program is a mail notifier, and I'd like to know when I have
new mail without unblanking my screen, something I'm used to with xbuffy
under linux.  The LEDs I'm thinking of are the caplocks light, the light
to the left of the latch for the lid, and the LED on the power
connector, but if there's another I haven't thought of that would be
fine too.  A google search didn't turn anything up...

I agree that would be cool to do, but I don't know how to do it.  Does
anyone else here know how to blink the LEDs on a MacBook?

HI

Apologize me for this mail if it is off topic here...

i'm new to python,
i've just a little experience about this wonderfull language :-)

i'm tring to configure a python web processing server "pywps" on my mbp

http://pywps.wald.intevation.org/

it is an open project to port python environment on the web
to use it in on-line  mapping application like web-gis

i'm tring to configure it on mac osx but it don't works as aspected,
i tried to resolve the problem with the developpers of pywps but they  
haven't a mac machine to try it :-(

pywps is designed to use application like
R
or
GRASS
installed on a server
and use this application with local data trought the web ,  with  
local data.

to configure and try it,  a Grass installation is needed,
have any experience about?

i'v grass installed from source and i followed the instruction to  
install pywps,
but i've an error to import the "subprocess"  routine
(colling it from pyshall :
- import subprocess
  it works )

the error that i've is :

./wps.py "service=WPS&version=0.4.0&request=getcapabilities"
Traceback (most recent call last):
   File "./wps.py", line 74, in ?
     raise ServerError(e)
   File "/Library/WebServer/CGI-Executables/pywps-2.0.0-rc3/pywps/Wps/ 
wpsexceptions.py", line 105, in __init__
     raise NoApplicableCode(value)
pywps.Wps.wpsexceptions.NoApplicableCodePyWPS NoApplicableCode: No  
module named subprocess
Content-type: text/xml

to configure it this is what i done :


cp /pywps-2.0.0-rc4    /Library/WebServer/CGI-Executables/pywps-2.0.0- 
rc4/
cd /Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/
python setup.py install
ln -s /Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/wps.py / 
Library/WebServer/CGI-Executables/wps.py



i'm very happy if anyone mac python expert, woul?d give me an help to  
figure out :-)

if you wont try it, i can post the instruction
needed to have a mac grass installation.
(it have a .app  make file to build a binary installation
to solve the grass dependancies a really nice frameworks are avaible  
on :
http://www.kyngchaos.com/software/unixport/ )


thanks for any suggestion about!

Massimo.

"No module named subprocess"
seems rather clear to me, even if that normally rises an ImportError.

I guess you run Python 2.3?
AFAIR subprocess is a core library since 2.4, before you could  
install it separately.

I haven't used GRASS, but Barry Rowlingson just presented at FOSS4G about an 
integrated system called "Arlat" using Quantum GIS (available for Mac OS X) for 
desktop mapping and R as a statistics engine, connected with Python.

http://www.foss4g2007.org/presentations/view.php?abstract_id=135

He is planning on posting details to the R-SIG-Geo list 
(https://stat.ethz.ch/mailman/listinfo/r-sig-geo), but there is a paper 
describing the implementation here:
http://www.bepress.com/cgi/viewcontent.cgi?article=1103&context=jhubiostat

I'm looking into this for use with MapServer:
http://mapserver.gis.umn.edu/

William Kyngesburye has Mac OS X binaries of MapServer at his kyngchaos site, 
although I don't recall if they use Apple's Apache 1.3 or permit you to install 
your own Apache 2.

This doesn't solve your immediate problem, but if you want to serve up spatial 
data via a web interface, I think you'll find MapServer much easier to use than 
rolling your own.

I assume, but don't know for certain, that MacBook keyboards are USB  
HID devices. In that case, this document:

http://www.usb.org/developers/devclass_docs/Hut1_11.pdf

discusses extended HID usages, including those which can be used in  
toggling on/off controls, of which LEDs are one instance.

 From there, I'd go to the IOKit framework and see what APIs exist for  
playing with OOCs. IOHIDUsageTables.h contains useful constants.

building stuff on OS-X is often a bit different than other *nix systems. 
I'd recommend that you try using these packages:

http://www.kyngchaos.com/software/unixport

And also use the Framework Python 2.5 from:

http://pythonmac.org/packages/py25-fat/index.html

That's a good source of other assorted packages that you may need, also.

Good luck!

-Chris

Hi,

thanks for the suggestion,

already i've installed on my mac

grass, qgis, R, ossim, ossimplanet, mapserver + kamap
all works fine :-)
thanks to william and to all mac comunity (really great people !)

i'll try to explain why a wps :

i need pywps beacouse my targhet is to have a web-processing server  
(not a simple web gis)

i.e.  use the function of grass and R (installed on a server) through  
the web, by a web-gis interface
called from a kml file  loaded into ossimplanet.

something like "embrio" or "openlayer + pywps" :  http:// 
pywps.ominiverdi.org/

i need this solution to try the integration of ossimplanet too

ossimplanet is able to load kml file and wms map


i done a script to produce kml , elevation-data and  wms map  from  
grass data,

using pywps  i can integrate this  script in ossimplanet using the  
"kml" as connection point


apologize me for my englesh and   for the bad explanation of what i  
want try to do :-/


let me know if anyone wont help me toinstall pywps :-)

thanks for any suggestion!

Massimo.

You need to tell us what you've done so far, and what the errors are. IN
any case:

1) install the Framework build of either python2.4 or 2.5 (whichever one
the pywps folks are using)

2) What python external modules does pywps require? Are they in the
repository at pythonmac.org/packages

3) Does pywps have any compiled components? If so, try building them
with "setup.py build". If that doesn't work, what errors do you get?

etc....

HI

how defoult i'm using the framework build  2.5 :

Python 2.5.1 (r251:54869, Apr 18 2007, 22:08:04)
/Library/Frameworks/Python.framework/Versions/2.5/bin/python

i'v also :

- Python 2.4.4 (#1, Oct 18 2006, 10:34:39)
   /Library/Frameworks/Python.framework/Versions/2.4/bin/python2.4

whith a sim link in :
/usr/local/bin/python2.4


and a fink installation  :
- Python 2.4.3 (#1, Aug  8 2007, 21:43:02)
   /sw/bin/python2.4


 From the pywps doc about the required extra packages
  (only xml is required )


this is what i done to install pywps :

- unzip the archive pywps-2.0.0.tar.gz and copy the pywps-2.0.0-rc4  
folder in :
  /Library/WebServer/CGI-Executables/
- cd /Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/
- python setup.py install
- ln -s /Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/wps.py / 
Library/WebServer/CGI-Executables/wps.py

in
/Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/pywps/processes/

- renamed

   __init__.py-dist
   to
    __init__.py

   and
  addvalue.py-dist
  to
  addvalue.py

in
__init__.py

- added a comment to
   all processes axcept for : addvalue.py

   it looks like :


__all__ = [
         "addvalue",
   #      "classify" ,
   #    "flow",
   #     "ndvi",
   #    "shortestpath",
   #   "spearpath",
   #      "visibility",
   #      "inputsoutputs",
   #      "buffer",
   #      "convert",
	]


-  created a directory in :

   /Library/WebServer/Documents/wps/wpsoutputs/

  ( it have read-write permisions )


-  modified the file :

    /Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/pywps/settings.py

   /Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/pywps/etc/grass.py

to reflect my environment


to test if it works (as explained in the docs)
i tried to run :

cd /Library/WebServer/CGI-Executables/pywps-2.0.0-rc4/pywps/
./wps.py


http://rafb.net/p/lvWEOw58.html
http://rapidshare.com/files/59870693/pywps_setting.tgz.html


i have grass installed from source in :

/usr/local/grass-6.3.cvs


this is the error log :

i've a scarse knowdledge about the web tools that we can use
i do not know what tools can i prefer to do this.
i've decided to use pywps, only beacouse whit it  i can use a grass  
sintax
to performs processes and use a lot of grass commands  that is  
familiar to me.


can other tools cominicate with grass as well we can do using pywps ?

to produce wms map i'll use mapserv as it is, so no pywps for this,
what probably i need is to set-up a link into the kml that point to a  
form
where one can select what grass layer want convert to wms feature
use wps to export the layer (or produce it if no exist ... like ndvi  
etc..)
then use a script to produce a mapserv wms map to
  (at the moment i ignore how manage this part, never tried it)

and use pywps  to run specific grass script to produce some output
loadable with ossimplanet and put this output in a ftp connection
to download and load it.

What's the first line of 'wps.py'? I get the feeling that wps.py is  
using a different python interpreter than you are thinking it is.

yor're right!!!

it use as interpreter :

#!/usr/bin/python

that is the osx standard python 2.3


changing to the right environment i not have the "subprocess" error :-)


now i'll try to read more about the pywps setting and try to  
configure it to do some example.

and see what happens.

thanks to all !!!

hi

there was a gui version for py2exe (windows equivalent of py2app) but i 
dont know any for py2app. Anyway if what you are doing is simple you can 
easily deal with the setup.py script.

this is the py2app documentation
http://svn.pythonmac.org/py2app/py2app/trunk/doc/index.html
the option reference
http://svn.pythonmac.org/py2app/py2app/trunk/doc/index.html#option-reference

Attached there is an example of a setup.py script that uses pygame, i 
think it should work, you just need to edit the name variable and run it 
like this
$ python setup.py py2app

However if you have assets like images, sounds etc... you need to make 
sure that they are also included, check the extra_file variable. IN that 
example it will put a file "data/slicer_pd.pd" into a folder called 
"data" inside the app. Otherwise keep extra_files = []

Please anyone correct if there is anything wrong, i just quickly put 
this together from another more complex script.

good luck

Message-ID: <c314d7d20710030724m7f7038ucec0ffd50979d57f@mail.gmail.com>

Hi,

I've recently moved to the mac from windows (some experience on
unix/linux too). I programmed a lot in C++ and a fair amount python. I
much prefer coding in python these days. I've written a lot of user
interface code (MFC/wxWindows/wxPython), and I'd like to get up to
speed to writing some presentable applications on the mac using the
native tools. I was wondering how best to make a start.

A few questions (but any hints would be good)

Do any of the experienced mac developers out there recommend doing
everything in python? Or should I dabble with objective-c applications
first?

I've seen the pyobjc examples, but are the people out there writing
complete applications just using python? Are there any open source
examples?

Is there "the book" for learning the basics of the mac system?
Likewise, is there a book on objective-c for experienced programmers?

Thanks in advance,
Brett

You can do pretty much anything you want in Python--nearly all of the 
major toolkits (Cocoa/Objc, wxPython, Tk, PyQt) are natively supported 
on the Mac. I develop a commercial application in Python/Tk-Aqua. See 
http://wiki.python.org/moin/MacPython/MacSoftwareUsingPython for a 
partial list of Python apps on the Mac.

RestEdit is open-source; Google for its current location.

Aaron Hillegass's book on Cocoa programming is highly recommended.

+1 there.  If you already know Python and C it should be easy to learn Objective-C, the hard part is learning about the Cocoa libraries and there a book like the Hillegass one can be very helpfull.

I attended the Big Nerd Ranch Boot Camp this Spring, which is a  
perfect introduction to native programming on the Macintosh platform.

I had never programmed Mac OSX via Objective-C before.

I have yet to really use these skills for a full application, but now  
I know enough to find my way around the guts of a Mac application. I  
may go ahead and write apps in PyObjC now that I know about the GUI,  
NIB files, bindings, and the like.

http://www.bignerdranch.com/
http://www.bignerdranch.com/classes/cocoa.shtml
http://www.bignerdranch.com/classes/python.shtml


I was able to re-package our open-source application suite as a  
Macintosh application bundle with a bunch of shell scripts and lots of  
install_name_tool re-mangling of the Python frameworks etc. I wish I  
knew more about py2app in order to make this easier, but I did it all  
"by hand" and by inspecting the layout of a "hello world" program  
created by py2app.

Our application (CASA) is a rather complex scientific data analysis  
application, implemented mostly as a bunch of C++ wrapped by Python,  
with a GUI or two via Qt.

While CASA is a lousy example of a "typical", GUI, Apple application,  
it's a nice lesson on deploying a (mostly) command-line shell tool on  
a Mac as an application, without alienating our "switcher" user base  
of scientists that are coming from a Linux environment.

So it may be of interest to see how I wrapped the generic python  
application via an AppleScript launcher (which in turn calls a shell  
script and then launches a Terminal window, runs a C++ wrapper than  
*finally* calls a Python script to setup IPython).  Yeah, that  
bootstrap process is way too convoluted, but it'll get better.

The program is NOT released yet or intended for general use (no  
support provided), but you're welcome to take a look at it:

https://wikio.nrao.edu/bin/view/Software/ObtainingCASA

At the moment (3 October 2007) the PowerPC version is still a tarball  
that installs a UNIX-y collection of libraries and Python; it's not a  
Mac "application".  The same thing is re-packaged as a "real" Mac  
application in the Intel version. By comparing the two you might learn  
something. I don't know. GPL'd.

I attempted to write some of this up in a poster:
http://www.aoc.nrao.edu/~bwaters/papers/WWDC-2007-CASA-poster.pdf

Hope this helps... it's not the recommended "Mac way" to do things,  
but it's how we ported from Linux.

I don't know if you are a podcast listener. There is a helpful Mac /
Objective C available through iTunes called Cocoacast
(www.cocoacast.com) which uses Aaron Hillegass' book to teach
ObjectiveC.

Thanks to everyone for their replies; very useful stuff.

I must say that getting a large number of replies so quickly is also
incredibly encouraging. It is good to know that there are people out
there who love python and work on the mac!

Thanks again,

Hi Brett,

Yep, There's plenty of us!
Many I know migrated from FORTH at one end and APL at the other ...
the important continuity being an interpretive environ. which is more  
conducing to figuring out what one is actually trying to do.
Having done that, we can crunch CPU cycles using C/Fortran etc  
libraries if needs be.

Whilst not specifically a mac thing, the python community is well  
entrenched nearly everywhere and there are some fantastic tools which  
can be integrated.
Its not a  single piece of software, nor even finished project,  but  
you might like to look at my sonipy.sourceforge.net for some toolset  
ideas.
It is being developed in the first instance on OSX.

good luck!

David

Message-ID: <20E87624-14A8-4F60-AF39-77F1AE05A167@sbcglobal.net>

Hello,

I just subscribed to this list, so please allow me to introduce  
myself. Although I am a long-time Mac user, I just recently started  
learning python. My primary interest in python is as a way to create  
simple programs with which to run psychological experiments (I am an  
experimental psychologist). This means that I need to be able to  
create simple GUIs to collect behavioral measures from research  
participants, such as response times (how long it takes them to  
respond to a stimulus after appears on the screen).

Given this, I was delighted to discover easygui, a module for  
creating simple GUIs. When I tried to run it following the  
instructions that I downloaded from the python website, however, I  
couldn't get it to work on my iBook g4. I did not get an error  
message, but no buttons or dialog boxes appeared, either. Can anyone  
on this list tell me if easygui works on the Mac, and if so, what  
steps I need to take to make it work?

Your assistance with this problem would be grately appreciated.

Cordially,
Rafael Bejarano

I would suggest
visionegg
www.visionegg.org
perfect for experimental psychology experiments, at least mine, and  
installs nicely on the mac with some gui demos.
All python, and cross platform.
there is also psychopy, which looks similar to visionegg, but I've   
not had the need to try it.
hope this helps

Hi Rafael,

I'm not familiar with EasyGUI, but it uses Tkinter, which I try to
avoid on the Mac.  If you need an easy way to create GUIs and you're
OK with it being Mac-specific, then I'd recommend using Interface
Builder (comes with the free OS X developer tools) to create your GUI
and PyObjC to write the application in Python.  If you need
cross-platform GUIs, that won't work, but for the Mac it is the best
choice.  If you have problems with any of that, I can give more
pointers, but for starters:

http://developers.apple.com/  for developer tools and Interface
Builder docs (requires free account to download latest developer
tools)

http://pyobjc.sf.net/  for PyObjC, the Python/Objective-C bridge
(gives you access to all of Apple's Cocoa libraries from Python)

It works fine for me using Python 2.5.1 on MacBook Pro. I don't think I 
did anything special to install it.

@Dethe:
EasyGUI is very limited in what it does--it basically provides some 
canned dialogs, nothing more. It's similar to EasyDialogs from the older 
MacPython days. My guess is PyObjC would be overkill or too complicated 
for his needs (otherwise he'd be writing his GUI in Tkinter).

@Rafael:
Running EasyGUI itself is as simple as double-clicking "easygui.py" in 
Finder. It brings up a demo with illustrations of the various 
dialogs/widgets that EasyGUI can implement. Without a bit more 
information about what you are doing, I can't help diagnose the problem.

I just had a quick look at the description of VisionEgg, and it  
appears to be far better suited to my needs than easygui is. So,  
Before asking for additional help with easygui, I will first explore  
VisionEgg in greater depth.

Thanks to everyone for responding so promptly to my request for help.

I did find a solution, but it involves using another script to edit
the setup.py script created by py2applet. (If anyone knows of an
easier way to do this, let me know.) Make the following changes to
setup.py:

includes = []

OPTIONS = {'argv_emulation': True,
            'plist':plist,
            'includes':includes,

Next you will run the following script in the same folder as your
setup.py. Put the names of the packages you don't want included in the
skip list.

#Collects all standard modules with paths and inserts them into the config file
#for py2app.

import os
import os.path
import sys
path = '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5'

modules = []
skip = ['site-packages', 'lib-tk', 'test', 'idlelib']

for root, dirs, files in os.walk(path):
    for item in skip:
        if item in dirs:
            dirs.remove(item)
    for f in files:
        d = root.replace(path, '')
        full_path = os.path.join(d, f)
        if '\\' in full_path:
            full_path = full_path.replace('\\', '.')
        if '/' in full_path:
            full_path = full_path.replace('/', '.')
        if full_path[0] == '.':
            full_path = full_path[1:]
        if full_path.startswith('plat-mac.'):
            full_path = full_path[9:]
        if full_path.startswith('lib-scriptpackages.'):
            full_path = full_path[18:]
        if full_path.startswith('plat-darwin.'):
            full_path = full_path[11:]
        if full_path.startswith('.'):
            continue
        #Ignore .pyc and .pyo files
        if f.endswith('.py') \
            and not f.startswith('_'):

Rafael,

You might also want to consider using Applescript Studio and then
making "do shell script" calls to python.  This is quite effective for
simple dialog boxes.  I have made a few of these applications and they
have a huge bang for the buck.

Hi Rafael,

Not a comprhensive list by any means, but here are a couple of my links:

http://www.psychopy.org/

you may find this useful:
  http://psy.ck.sissa.it/OtherStuff/OtherStuff.html

also pythoncard has lots of examples which might get you into a  
ballpark:
http://pythoncard.sourceforge.net/

the wxpython community may have some other references.

You'll notice that the visonary egg producers have chickened out of  
audio. :-)

I've yet to find a satisfactory Mac/psych testing package that deals  
with audio well.
(such that you can play audio and have people answer questions about it.

Does anyone have any suggestions in this regard?

Thanks for those pointers.  Unfortunately, I did a fair bit of googling
but couldn't find anything about how to play with OOCs.  The pdf you
linked to, and the .h file you mention, say to use "single button
toggle" mode, but I couldn't find anything about that, either. 

Any other suggestions?  Is there a more appropriate mailing list I
should try?

Thanks,

Dan

Don't overlook Pashua and CocoaDialog. I've used Pashua and it is  
incredibly easy to use. You write a simple text file and Pashua reads  
it and sets up the dialogs etc. that you specify. Pashua itself is a  
native Cocoa application. The download includes a Python example.  
(Pashua works with any language that can read text files.) The kinds  
of things that you can do is somewhat limited but it sounds like it  
might be enough for your application.

I can't stress how easy Pashua is to use.

CocoaDialog is similar but I haven't used it myself.

I've had some occasions to fight with getting audio working like I  
want in visionegg and had no problems beyond the normal 'nothing- 
working-like-you-expect-the-first-time'.

I've been using it for presenting stimuli for eye-tracking and  
sentence comprehension, and I just make sure all my stimuli are aiff  
or wav. Really it's been much less bug prone than my experiences with  
director, e-prime and psyscope. If you need to present video it's a  
little more of a hassle, but not so much.

What problems were you having with visionegg and audio? I'm happy to  
help if i can.

Thanks again for those pointers!  I looked through them but didn't find
anything about OOCs.  And a search of the apple developer connection
website for "on/off control" only turns up hits about power buttons.
I did find two links that might be relevant.  This first says there is
an "ADB/USB shim [that] allows applications to set the caps lock LED on
the Apple USB keyboard", but I'm not sure if this will be helpful:

  http://developer.apple.com/documentation/Hardware/Developer_Notes/Macintosh_CPUs-G4/PowerMac_G4_16Feb00/G4Rev3-43.html

The second mentions kHIDUsage_KeyboardLockingCapsLock:

  http://developer.apple.com/samplecode/GLCarbonAGLFullScreen/listing12.html

Unfortunately, given that I've never programmed in Objective C before,
this is probably getting beyond what I have time to figure out myself.
I may try asking on another list to see if someone can point to explicit
code that already does what I want.

I appreciate everything that people on this list have done!

Dan

Check out Dabo -- it's pretty slick, and not just for database apps 
(though it's great for those) (wxPython based)

They are each the top links on Google using the programs' names.

P.S. They are both free.

hello,

for simple gui's using different media (audio, video, openGL etc )  
you might consider pure data (open source) http://en.wikipedia.org/ 
wiki/Pure_Data or max msp jitter (expensive... cycling74.com)

both environments have objects which enable you to integrate your  
python code.

maybe this helps...

Hi Robin,
I know them both very well. Good at what they do. Supercollider is  
even better (IMO)
However they both only have python for scripting. If it's python you  
want, approach with caution ....

I don't know visionegg so I went to their website entered a couple of  
audio words into their search engine and they all drew a blank.
So it's nice to hear that it has an approach to audio. I'll check it  
out.

Subject: [Pythonmac-SIG] P4Python, MySQLdb, or Python Extensions
Message-ID: <8532cb8c0710081357g1f3e31f8gb4fa4172c60e68df@mail.gmail.com>

Hello everyone,
Short time lurker, first time poster.

I'm trying to install P4Python and MySQLdb, but am running into a host of
issues.

The trouble I've had trying to install these two and the number of similar
experiences I've read through googling leads me to believe that Python can
be difficult on the Mac.

I will talk about P4Python as it seems to be the easier of the two. I'm
trying to compile the given c++ file to build a Python Extension, but the
setup.py doesn't work as it should be linking in CoreFoundation, but it is
not.

ImportError: Failure linking new module:
/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/P4Client.so:
Symbol not found: ___CFConstantStringClassReference
  Referenced from:
/Library/Frameworks/Python.framework/Versions/2.4/lib/python2.4/site-packages/P4Client.so
  Expected in: dynamic lookup


I tried to use Xcode to build something that can go where the site-packages
go. But I have no idea what to build. It is not a dynamic library, it is not
a relocatable object, I get this error when I try to import:

Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "p4.py", line 19, in ?
    import P4Client
ImportError: Inappropriate file type for dynamic loading


Has anyone done this? How do I build a Python Extension using Xcode? Or
perhaps even better, how do I get setup.py to work on the Mac?

Thanks for any and all tips!
Lyndsey Ferguson

.so, if im not mistaken is eather a linux shared library or not a mac shared
library (someone correct me if im wrong) try making sure the python version
you chose is the one for mac. the best supported python for mac is
macpython<http://www.python.org/download/releases/2.5.1/>(distributes
in a mac installer package) from the python website but another
more linux like one would be the darwinports one or the fink one. Try
looking here

Thank you for the reply. I have removed older versions of Python and using
your link, installed Python 2.5 for the Macintosh.

After which I tried to build and install with the same problem. But I have
solved it and will post it to the author and this list (in case someone
follows in my footsteps).

In the setup.py for the Macintosh case, I had to add the
"extra_link_args=["-framework", "Carbon] to the setup call. This works and I
was able to run it in python.

Regards,
Lyndsey Ferguson

Shouldn't distutils do this for you? Anyone know?

I'm debating when to move my own development machine to Leopard. Right 
now all the components that I use to assemble my Python app were built 
on 10.4, so I know they should run on both 10.4 and 10.5; I want to 
continue to support 10.4. However, will an application that is bundled 
by py2app on 10.5 run on 10.4 if all the frameworks were originally 
build on 10.4? Does py2app introduce any kind of additional compilation 
that would break backward OS compatability?

py2app does not cause additional compilation. As long as the python  
framework and all extensions and shared libraries  are build for 10.4  
the resulting .app should work just fine.

In theory it should even be possible to build extensions on 10.5, as  
long as the python framework is build with the 10.4u SDK and  
MACOSX_DEPLOYMENT_TARGET is set to 10.4. That's not something I've  
tested though, just compiling all C/C++ code on a 10.4 system is  
therefore the safest course.

Subject: [Pythonmac-SIG] Audio_mac.py fails in writeframes
Message-ID: <470E547B.30401@cse.msu.edu>

I'm running 'OS X' 10.4.10 and python 2.5.1 on a MacBook Pro SR. When I 
try to run any of the audio demos, specifically Audio_mac.py, I get 
errors. The error is in the writeframes method. It appears to try and 
pack the constant extSH (set to 0xFF) as a signed byte, which it cannot do.

I've searched all around and found one guy on the net with this problem 
but no answer. I can over-ride the writeframes method but what should 
extSH be?

Any help appreciated.

Change the struct.pack format from 'llHhllbbl' to 'llHhllBBl'.

The code predates the distinction between signed and unsigned bytes  
in struct.pack.

But be warned that this also shows how well-maintained the code is:-)

Subject: [Pythonmac-SIG] Packaging Imagemagick into wxPython standalones.
Message-ID: <995EA334-1D41-43B0-A227-756CE6C39C30@ou.edu>

I am creating a very simple front end to a vector graphics package  
that one of my professors wrote.  His package writes the images out  
in .eps format. So in my code I just call ImageMagick's 'convert'  
function to jpeg. From jpeg I can use wxPython's ConvertToBitmap()  
feature to display the image to the user. This works great from the  
command line, but when I try to make a standalone with py2app, it  
fails due to 'convert' not working.

When this didn't work, I tried using PIL and converting by Image.open  
and Image.save. Again, this worked great from the command line, but  
failed in the standalone version.  I suspect it is likely that I am  
not including all relevant libraries needed for this to work.

Has anyone had any experience using ImageMagick or PIL in a  
standalone application to convert image types?

Thanks for any help.

PIL works fine in a stand-alone in general, but....

both ImageMagik and PIL are raster format packages. EPS is a vector 
format, so I think both PIL and ImageMagik use ghostscript to render the 
EPS for you, and I think they both use it as an external application, so 
the users of your stand-alone are going to need to have ghostscript 
installed.

Also, when using ImageMagik, are you using the python bindings? or 
calling "convert" as a system call?

Jeremy,

You should include the error trace when posting problems and  
preferably snippets of the misbehaving code.  I had a similar problem  
with a py2app attempt that turned out be my not having a resource  
data directory included in the bundle that was built.

I should also mention that the error doesn't occur if I delete the

I have been getting ready for the official leopard release in a few days,
and have been a bit worried about readline support.  I forgot what I did to
get it to work for IPython, which I absolutely cannot live without anymore.
Is there a plan for a Leopard binary that fixes readline, or can I help
someone prepare some documentation on getting readline working properly.  I
don't have a lot of time during the next couple of weeks to get into compile
hell, but if someone has any easy fix to get readline to work, I would
greatly appreciate it.

Just install GNU readline and point the build system at it.  For example, I
have MacPorts (http://www.macports.org/) installed in /opt/local.  GNU
readline is installed there, and my readline module is linked against that:

    % otool -L ~/local/lib/python2.6/lib-dynload/readline.so 
    /Users/skip/local/lib/python2.6/lib-dynload/readline.so:
            /opt/local/lib/libreadline.5.2.dylib (compatibility version 5.0.0, current version 5.2.0)
            /opt/local/lib/libncursesw.5.dylib (compatibility version 5.0.0, current version 5.0.0)
            /usr/lib/libmx.A.dylib (compatibility version 1.0.0, current version 93.0.0)
            /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.10)

Configured like so:

    ./configure  --prefix=/Users/skip/local CPPFLAGS=-I/opt/local/include \
        LDFLAGS=-L/opt/local/lib

I don't do framework builds, but if CPPFLAGS and LDFLAGS are set
appropriately those should work as well.

No. There are a number of good books on Python programming in general and those should get you going on the Python side. For the most part Python on the mac is just like Python on other unixy platforms.

I know of no books that deal with mac-specific issues (like applescript and Cocoa) from the Python perspective, but that shouldn't be a problem unless you want to use mac-specific technologies. W.r.t. applescript: appscript is very useful and has good documentation. W.r.t. Cocoa: PyObjC does not have extensive documentation, but it should be easy enough learn just enough Objective-C to learn about Cocoa from the myriad of Objective-C Cocoa books.

Has anyone found a reliable method to add Safari bookmarks via Python (or

I have used plistlib to modify the Safari Bookmarks plist, but something is
?going wrong?.
Safari happily uses the bookmarks, but iTunes is not syncing the new
bookmarks to the iPodTouch that I am trying to use...

So I suspect I have a subtle error in my Python code...  So has anyone found
a better (or alternative method) to do create safari bookmarks?

Are you asking about struct definitions and such? For example:

from ctypes import Structure, c_float, c_double

class PMRect(Structure):
     _fields_ = [
         ("top", c_double),
         ("left", c_double),
         ("bottom", c_double),
         ("right", c_double),
     ]

class CGPoint(Structure):
     _fields_ = [("x", c_float), ("y", c_float)]

class CGSize(Structure):
     _fields_ = [("width", c_float), ("height", c_float)]

class CGRect(Structure):
     _fields_ = [("origin", CGPoint), ("size", CGSize)]

Those are the only ones I've used, and luckily they're pretty simple.  
I do not know of a library of definitions for standard CF types. Sorry.

AFAIK you don't need to do anything special (i.e. write "ctypes  
definitions") to call the CF functions with ctypes. Just call them.  
Here's a snippet of code that I use to open a PDF document and get  
the number of pages:


from ctypes import cdll, byref, c_void_p, c_int, c_uint, c_float,  
c_double
from ctypes.util import find_library

cf = cdll.LoadLibrary(find_library("ApplicatonServices"))

filename = "/path/to/document.pdf"

kCFAllocatorDefault = None
kCFURLPOSIXPathStyle = 0

# open pdf document
fileref = None
fileurl = None
try:
     fileref = cf.CFStringCreateWithCString(None, filename, 0)
     fileurl = cf.CFURLCreateWithFileSystemPath(
         kCFAllocatorDefault,
         fileref,
         kCFURLPOSIXPathStyle,
         0
     )
     pdf = cf.CGPDFDocumentCreateWithURL(fileurl)
     if not pdf:
         raise PrintError("cannot open PDF document: %s" % filename)
finally:
     if fileurl:
         cf.CFRelease(fileurl)
     if fileref:
         cf.CFRelease(fileref)

numpages = cf.CGPDFDocumentGetNumberOfPages(pdf)

if pdf:
     cf.CGPDFDocumentRelease(pdf)



My experience with developing code like this is that it takes a lot  
of patience and trial and error to get it stable. Remember that  
you're dealing with C functions and pointers (it's called ctypes for  
a reason), which are not nearly as forgiving as normal Python  
functions and objects. For example, calling a C function with the  
wrong argument types will generally cause a cold hard segfault rather  
than give you a nice stack trace with some indication of what caused  
the error. When all else fails read the documentation for the library  
you're calling...again.

CoreFoundation is C, not C++.  That said, it'd probably be easier to
use PyObjC with NSMetadataQuery instead.

How did you do the source install?

For py2app in particular, easy_install is the easiest way to get it.

Other than that, maybe some more specifics would help -- which versions 
of python, wxPython, wxGlade? a copy of your setup.py, text of the 
errors, etc, etc.

Unfortunately, the Objective-C API is not as functional.

Looks like Thomas Heller has a system for doing this:

Unfortunately, it seems to be somewhat complicated, requiring the
checkout and install of cmake, gccxml, and ctypeslib.

Another option is to write the C wrapper in Objective-C (or find a
third-party framework that already offers the functionality you want),
then write a wrapper to expose it to Python using PyObjC.  I've had
success with this for using Quicktime features not exposed by Cocoa (I
found a third-party library) and the Python wrapper is about three
lines of boilerplate code, if I recall correctly.

For cross-platform stuff, ctypes is probably the way to go.  But if
you're targeting OS X anyway, the PyObjC approach has worked well for
me.

The installed version of python on Leopard will actually have readline  
support turned on by default, but it uses the EditLine (libedit)  
library, not the GNU Readline (due to licensing reasons).  While  
functionally equivalent, the command syntax is different.  From the  
python(1) man page:

INTERACTIVE INPUT EDITING AND HISTORY SUBSTITUTION
        The Python inteterpreter supports editing of the current input  
line and
        history substitution, similar to facilities found in the Korn  
shell and
        the  GNU  Bash shell.  However, rather than being implemented  
using the
        GNU Readline library, this Python interpreter  uses  the  BSD   
EditLine
        library editline(3) with a GNU Readline emulation layer.

        The  readline  module  provides the access to the EditLine  
library, but
        there are a few major differences compared to a traditional  
implementa-
        tion  using  the  Readline  library.   The command language  
used in the
        preference files is that of EditLine, as described in  
editrc(5) and not
        that   used  by  the  Readline  library.   This  also  means   
that  the
        parse_and_bind() routines uses EditLine commands.  And  the   
preference
        file itself is ~/.editrc instead of ~/.inputrc.

        For  example,  the rlcompleter module, which defines a  
completion func-
        tion for the  readline  modules,  works  correctly  with  the   
EditLine
        libraries, but needs to be initialized somewhat differently:

               import rlcompleter
               import readline
               readline.parse_and_bind("bind ^I rl_complete")

        For vi mode, one needs:

               readline.parse_and_bind("bind -v")

Also various online tutorials, if the OP's completely new to Python.  
Easy enough to find.

Yep, appscript is quite straightforward to use once you appreciate  
how it works. (It's basically a hybrid RPC+query-based system, not an  
object-oriented connected a-la COM or CORBA, and any syntax on top of  
that is just sugar to sweeten the taste.) The hard bit is dealing  
with the various bugs, quirks and inadequate documentation of the  
applications you want to script, but that's not something specific to  
appscript. Dealing with this tends to be a bit hand-to-mouth,  
involving a fair degree of intelligent guesswork, trial-and-error  
testing, studying existing scripts and generally looking and asking  
around for help. However, there's various folks here and in the  
AppleScript community who can provide advice on specific problems  
(and several mailing list and BBS archives you can search for past  
discussions) so don't be afraid to ask.

FWIW, this is how I did it: one copy of PyObjC (for obvious reasons),  
one copy of AppKiDo (for quickly looking up Cocoa API documentation),  
one copy of Hillegass (to grok the basic concepts behind Cocoa  
programming), one Google bookmark (for everything else), and just  
dived in and began writing code till it started to all make sense.  
The example code included with PyObjC is really handy for picking  
through and pulling apart to help understand the general principles  
and as a source of example solutions to various common design  
requirements. And again, there are plenty of folks here and in the  
wider Cocoa community (e.g. I also subscribe to Omni's MacOSX-dev and  
Apple's Cocoa-dev mailing lists) who you can ask for advice when you  
need it.

Edward,
Thanks for the information.  Do you know of a way to get IPython to use
edline instead?  IPython is growing in popularity for Python programmers,
and it seems like getting a way forward that works with edline makes sense,
or maybe I am wrong and people will need to just manually install readline
themselves.

Interesting.

FWIW I just built IPython against the system python (with libedit,  
apparently) and it works fine; I have readline-like command  
navigation, history support, etc.

I was not aware of any change from using readline (which is what I  
used with 10.4.x)

We did fix a few bugs related to IPython and Leopard's python, so to  
some degree, it does work (sorry, I don't use IPython myself).  There  
was a problem with IPython explicitly loading ~/.inputrc when readline  
support is available, which will fail due to the command syntax  
problem.  Just guessing, but converting the .inputrc to EditLine  
syntax *should* probably fix that problem.

Thanks, but no thanks.  I see no need to drag Objective-C (and PyObjC)
into this.

Anyone generated the CF types for CoreFoundation?

And now svn.python.org is down, so I can't get it anyway.

I am forwarding this to the ipython-dev list.  A number of the core
ipython dev's use OS X, so we will surely jump on this one as soon as
we get our hands on Leopard.  This (libedit support) is great news as
it has been one of the main problems with the built-in Python on OS X
for a long time.

Cheers,

Brian

Brian,

Thanks, I was just considering doing this myself.  I would be happy to help
document this if there is a suitable wiki for it, once a clear path gets
figured out.  If you do google searches for readline os x, or ipython, etc,
you will tons, of people who have had this problem for quite some time.
Getting clear documentation for OS X users will help the IPython cause
greatly.

I know in the book Jeremy Jones and I are writing, we covering IPython quite
a bit, as we think it is the preferred tool for sysadmins to write code in.
This is slightly off topic, but the doctest inclusion is the icing on the
cake as far as I am concerned with IPython.

Meh. That should've told me the solution straightaway - I put the  
CFBundleDocumentTypes entry in the wrong place. Fixed now.

In my defense, I got thrown by the quite cryptic setuptools/distutils/ 
py2app-generated traceback [1], which made it look like the problem  
was further down. Also, having nephew and niece no.1 dropped on the  
doorstep at 4am this morning while youngest sister headed off to  
hospital to have niece no.2 may have taken the edge off me today. ;)

Apologies for the bother,

has

[1] Any chance of implementing better error reporting here at some  
point in the future?

Here's that error:

stripping datetime.so
/usr/bin/strip: object: 
/PersonalStorage/Code/src/wxGlade-0.6/dist/wxglade.app/Contents/MacOS/python 
truncated or malformed object (linked_modules.offset field of

I know NOTHING about stripping, but it looks like it's having a problem 
stripping datatime.so. (or is the problem with whatever is next?)

I'd try a little app with nothing much but datetime, and see if that 
works. Also, you might try python2.5, just for the heck of it.

Bob or Ronald, any ideas?

Also, can you turn off stripping with py2app?

OK, I've build and run Thomas Heller's tool, and you can for the
moment get the generated ctypes CoreFoundation.py file from

I just wanted to compare the output with my experience of this tool  
for another bit of C, but I get a Forbidden:

this looks like a problem with the version of python that Richard is  
using. I haven't followed this discussion so far, but what version is  
being used? Is the the macports one, if so which version?

Which OS are you running on?

python setup.py py2app --no-strip

You might also try 'python setup.py py2app -A'. This will build an  
alias bundle which depends on the source tree and the local python  
installation, but is a convenient way of building during development.  
It does make it a lot easier to quickly check if you have packaged all  
resources (icons, xml files, ...) that the application needs.

Message-ID: <DC065D85-8646-4375-B8EA-3687D2DDC044@pacbell.net>


Pardon the cross-post.

Would anyone on this list happen to know the appropriate way to build  
and install _imagingft for use with PIL?  My Google searches have  
found references to it, source code, complaints, and disclaimers; but  
I have not found the info I need to build & install it.  I would like  
to render fonts.

Thanks in advance!

After looking more deeply into this, I believe that there are some
lower level issues that need to be resolved.  Doing so may bubble up
to fix the py2app+wxGlade issue.  Please  give me an opinion on my
system described below.  I have tried so may things to get py2app to
work that I may have left my system in an inconsistent state.

Yes, I have the Macports python2.4 and python2.5 installed.  Quite
honestly I'm always very confused as to which gets used, and what the
module path is.  Here are the pythons I have on my system:
/System/Library/Frameworks/Python.framework/Versions/2.3/bin/python2.3
/opt/local/Library/Frameworks/Python.framework/Versions/2.4/bin/python2.4
/opt/local/bin/python ->
/opt/local/Library/Frameworks/Python.framework/Versions/2.4/bin/python
/opt/local/bin/python2.5
/opt/local/var/macports/software/python24/2.4.4_1+darwin_8/opt/local/Library/Frameworks/Python.framework/Versions/2.4/bin/python2.4
/opt/local/var/macports/software/python25/2.5.1_1+darwin_8/opt/local/bin/python2.5

my env has:
PYTHONPATH=/Users/rbronosky/Code/python/site-packages

and finally there is:
python -c 'import sys;print sys.path'
[
       '',

I tried the aliased build on a simple py that I generated with
wxGlade.  The resulting app, when launched, gives me this error:
ImportError: No module named wx

I can't figure out how to get py2app to include the site-package dir

Please advise.

Richard,

If I were you, I'd give this all a try with the "official" Framework 
build you can find here:

http://pythonmac.org/packages/

I'd go with 2.5 unless you have a compelling reason to stick with 2.4 -- 
wither should work.

Also, I'd use that as your source for any other packages you may need.

We've tried very hard to try to create an aura of "officiality" around 
those builds (they are the same as the ones you get on python.org too). 
The whole deal with macports, fink, build-it yourself (differently) from 
the tarball, etc. just creates a nightmare of support.

I don't know if py2app is tested against the macports build, but I do 
know it's tested against these builds.

macport does a better job than fink of integrating with the system, but 
you still kind of have a unix-within-OS-X, rather than an integrated system.

Does wxPython with macports use wxMac, or is it wxGTK???

-Chris

Subject: [Pythonmac-SIG] Python control/integration of a Cocoa/Quicktime
	application?
Message-ID: <472190BB.9070505@edmstudio.com>


I have a couple of Cocoa/Quicktime developers working on a small custom 
application.  These guys are very capable at OS X programming but don't 
have any python experience.  I, on the other hand, have a lot of python 
experience but virtually no Mac development experience.  I could really 
do with some advice from someone able to see "the big picture".

A bit of background ... We are working on a museum exhibit where a large 
65" 1920x1080 screen attached to a Mac Pro is electronically positioned 
on a 4m industrial slide-track via a physical interface device.  Each 
millimeter of track corresponds to a different image in a 4000 frame 
photo-jpeg-encoded Quicktime.  The user tweaks the interface device, the 
screen moves, the image changes appropriately - that's the basic plan.

I have a python program on the Mac that determines, among other things, 
the screen location.   The OS X developers are going to write a 
full-screen Cocoa application that handles the display side of things 
(along with some tricks like: change to a new movie; tweak the opacity; 
add a second layer movie; etc.)  The question then: how to join these 
two codes?

Options (that I can think of, probably more worthy of discussion):

1) Get the Mac guys to write their application as a library that can be 
wrapped in pyObjC and invoked by my python program.  In this scenario, 
the result is only one process/program with no network issues.

2) Add networking code to both the python and cocoa apps in order to 
communicate (binary socket, XML over http, Bonjour, etc.).  Easy in 
python via Twisted, no doubt less so in cocoa.

As always, any advice is much appreciated.

Cheers,
Darran.

If I understand the architecture correctly I would go with option 1.  
And get the Mac guys to write their code in a reusable way, i.e. have  
them export enough low-level functionality in their API. This should  
be easy enough in ObjC.
It'll allow tweaking from the Python side, and if you're lucky during  
the project they'll see the advantage of Python and all jump on the  
bandwagon:-)

BTW: there's a potential third architecture that I can see: write a  
Cocoa app with a Python module embedded. This is similar to option 1,  
but depending on which technologies you use it may be easier to  
structure things with ObjC "in charge" in stead of Python. But if you  
also structure your Python code well it shouldn't be much of a  
problem to switch from design 1 to design 3 later in the development  
process.

Jack's already given advice on #1 and suggested embedding Python as a  
third option.

As for the IPC option, you're pretty well covered there too. The two  
high-level approaches I'd recommend investigating are:

1. Apple events using appscript/aem on the client side and OS X's  
Cocoa Scripting framework on the server side (although there are  
other options available as well).

2. Cocoa's Distributed Objects system, using PyObjC on the client side.

Jack and Has, thanks very much for the valuable advice.  This weekend 
one of the developers is going to have a first crack at implementing 
option 1, namely a library that we can invoke from python.

I've recommended that Douglas join this mailing list and ask questions. 
  My only concern is that most people coming to this list are probably 
python users (like myself) who want to write Mac apps.  Douglas is 
coming from the opposite tack - he's a hardcore Cocoa developer who 
doesn't know python at all.  With this in mind, do you have any pointers 
in designing a library that is easily called from python?

I wondered, for example, if he wrote the Objective C library and a 
separate Objective C test application to exercise the code, if the test 
app could then simply be ported to pyObjC?  This way Douglas wouldn't 
need to worry about python at all ...

As always, any advice is much appreciated.

Cheers,
Darran.

Oops, I spoke too soon when I said that readline support with  
Leopard's Python works for me with IPython.

Many things DO work, but tab-completion does NOT.

I am trying to get tab completion working.

Forget IPython, just try this "unit test" of rlcompleter with the  
Python that ships with Leopard:

See http://docs.python.org/lib/module-rlcompleter.html

  Launch python from a Terminal shell prompt.
  at the prompt, type the following commands:
  import rlcompleter
  import readline
  readline.parse_and_bind("tab: complete")

  Now, try it out: start some input, then hit the Tab key to get some  
possible completions:

  readline. <TAB PRESSED>

  The tab is passed as raw input, and the completer does not give any  
completions.

  Tried with both Terminal and xterm.


Reported as Apple Bug # 5563035

I've also asked the IPython devs for help - and volunteered to get  
this resolved somehow for them -- but I don't think it's an IPython  
problem (since you can do this from "raw" interactive python).

Here's hoping...

I was just going to say the same thing.  Getting this to work and then GVim,
and I will be quite happy.

It right there in my original message (and in the python man page).   
You have to use EditLine syntax:

readline.parse_and_bind ("bind ^I rl_complete")

Ed,
You are a genius! Thanks, I totally forgot you told me that.

So for the record when you launch IPython:

import readline
readline.parse_and_bind ("bind ^I rl_complete")

Then do something like:

import os

and you will get

In [5]: os.
Display all 234 possibilities? (y or n)

Ok, what is the easiest way to get IPython to automatically do this?  This
would be great to document.

Also, (shamelessly off-topic), if anyone has GVim working...let me know,
cough, it is for Python and it is on Mac :)

The rlineimpl.py module is the place in python where readline gets
imported.  I would look there and also I would look to see where
ipython is doing its equivalent of parse_and_bind.

Oh good grief... I'm a *user*. You can't expect me to *read*...

um.. what is the smiley-thing for hanging my head in shame?


Very happy to have this sorted out!

Leopard is great, folks!

Stay tuned for a patch!

something like

If you write an Objective-C framework, the python code to wrap it
using PyObjC is very short.  Here is an example I use to expose Tim
Omernick's CocoaSequenceGrabber framework to capture images from the
iSight camera:

<example>

import objc, AppKit, Foundation, os
if 'site-packages.zip' in __file__:
  base_path = os.path.join(os.path.dirname(os.getcwd()), 'Frameworks')
else:
  base_path = '/Library/Frameworks'
bundle_path = os.path.abspath(os.path.join(base_path, 'CocoaSequenceGrabber.fram
ework'))
objc.loadBundle('CocoaSequenceGrabber', globals(), bundle_path=bundle_path)
del objc, AppKit, Foundation, os, base_path, bundle_path

</example>

I have that saved as PySight/__init__.py so I can import * from
PySight to get all the objects and methods from the framework.  It
would be shorter, but I have some path manipulation so that it works
from the command line and from within an application bundle built with
py2app.  The bare minimum you need is:

import objc
objc.loadBundle('MyBundle', globals(),
bundle_path='/my/bundle/path/MyBundle.framework')

Writing a bundle in Python that can be imported by an Objective-C
application is similarly easy.  I have some blog posts on that topic
if you ever decide to try that direction.  The application just needs
to take Objective-C bundles as plugins, it does not have to plan for,
or even know about, Python in the bundle implementation.

OK, thanks... I'll try to put something in ipy_defaults.py

I'm trying to come up to speed on the new style configuration. I'll  
try looking through Trac for more info as well.

Dear Memebers,

Leopard is arrived and on my Mac everything is working really great.
Now a question. I'm using python for my scientific research and I  
really need it. In particular I use pylab and scipy for their modules  
and for the graphical output.

Now on Tiger the python version was older (2.4) than the one provided  
with MacPython 2.5 but on Leopard there is already the 2.5.1 version.  
For this reason I tried to install matlotlib without installing  
MacPython. Unfortunately while I was installing the packages required  
for matplotlib.dmg package (dateutils etc...) the installation stopped  
because it was impossible to find system version Python 2.5... what is  
wrong!?

Do you think I should install anyway also MacPython before going on  
with dateutils and matplotlib!?

I'm just trying to install the less software possible and since ver.  
2.5.1. was aready there would be nice to use it and not to put an  
extra version.

Any ideas!??!

Best wishes. Rik

Where do you plan to put this? Configuring readline is done in config
files (ipythonrc), which don't really allow conditional actions.

I suggest you put it in ipy_defaults.py, and we'll advise leopard
users to ignore the ipythonrc and move to the new style configuration
(ipy_user_conf.py).

Honestly, this is so important that I'd rather have it in the core so
it works for any user, without bugging them about updating their
config setup or having to think at all.  If they have requested
readline support, then it should just work.  We already have
platform-specific code to work around a  things in Windows, having a
little bit of Leopard support doesn't bother me one bit.

Have a look at the attached patch, and if something like that works
well, we can easily just drop it in.

Cheers,

If you can hold out for a few more days, I'm working on MatPlotLib  
integration with Leopard's Python 2.5.1

We use it for our data analysis software; one of my jobs is  
maintaining our Mac Intel implementation.

I had had a pre-release of Leopard for quite some time, but alas we  
shipped an important internal milestone for our software just two  
weeks ago. It's been non-stop for me, and I haven't made much time to  
really look carefully at Python/MatPlotLib/SciPy and Leopard. But  
I've been working on it for about a week now.

I could make an installer package of the matplotlib bits that will  
work with Leopard Python.

I expect next Wednesday for matplotlib. Unless someone beats me to it.

Anyone?

There are some things you can do in ObjC that are difficult to expose  
to Python, but as they're so unusual I've never come across them I've  
also conveniently forgotten what they are:-)

Oh yes, I think if you pass a C structure you have to do some  
massaging (excpe tif PyObjC already knows about that structure, such  
as for NSPoint and such, then the work has already been done for you).

If you do this very early during development, i.e. when the library  
API has only a couple of calls you have the ObjC programmer write a  
minimal test script which you then port to Python, you could give  
this back to the ObjC developer. There's a very good chance this'll  
teach them enough Python to continue the testing directly in Python.

FWIW, this patch works for me.  I'm on IPython 0.8.2.svn.r2841.

This was driving me nuts for some time -- after all, the _Ruby_ shell  
(irb) had tab-completion in Leopard, so why shouldn't Python/ 
iPython?   I hadn't found the time to figure out a solution, so hooray  
for user communities.  I say commit the change.

Thanks -- you guys made my day!

Hi all,
I trie to install mysql-python 1.2.2 but I have a lot of errors. I have install MySQL 5.0.45 and python 2.5.1. I use Mac OS X 10.4.9 and when I trie to build mysqldb i have the following and famous error:

>sh: line 1: mysql_config: command not found

I trie to install the mysqldb but I have however errors.
I don't know where I have to do the change suggested in various sites and posts relative to:

return popen(?mysql_config --%s? % what)   (1)
                to          
return popen(?/usr/local/mysql/bin/mysql_config --%s? % what) (2)


In the python.py of the mysql-python-1.2.2 there isn't a line like (1). While, in the file site.cfg I don't know what I have to change like someone suggest to eliminate the problem of the installation.  
I also trie to install mysql-python-1.2.1_p2 and edit the setup.py by changing the line how suggest previously but I have the following error:

>File "setup.py", line 26
>    f = popen(?/usr/local/mysql/bin/mysql_config --%s? % what)

Can someone help me please?

Thanks a lot

I had many issues trying to do this.

Here is what I did:

Edit the file site.cfg so that the mysql_config path refers to /usr/ 
local/mysql/bin/mysql_config
In the terminal, type cd path/to/MySQL-Python then python setup.py  
build followed by sudo python setup.py install.

In the terminal, type ln -s /usr/local/mysql/lib /usr/local/mysql/lib/ 
mysql.

Confirm installation by typing in the Python environment, import  
MySQLdb.

I hope this helps,

Lyndsey

The problem is that the build system is trying to build a Universal  
Binary version of the library and you need to install the Universal  
Binary version of MySQL along with the libraries:

"/Users/alessandrocensoni/.python-eggs/MySQL_python-1.2.2-py2.5- 
macosx-10.3-fat.egg-tmp/_mysql.so, 2): Library not loaded: >/usr/local/ 
mysql/lib/mysql/libmysqlclient_r.15.dylib"

Is a hint, if you go to that directory, you'll see that running the  
command line tool "lipo" will tell you that the library  
libmysqlclient_r.15.dylib is not Universal.

You need to get the Universal Binary version of the MySQL library from  
the www.mysql.org website. Get the UB version and install it --  
removing the old version of MySQL.

Sorry I neglected to mention that, there are quite a few steps  
involved, it really is a pain in the butt.

Good luck!

I am afraid that this patch won't cut it.  It does a simple test of
the os type.  The problem is that someone could install a version of
python on OS X and want to use the other readline library (for example
the OS X python binaries from the python.org website ship with this
readline).  Somehow, we need to do a test of exactly what readline is
installed as well as an os test.  But, I won't have Leopard running on
my system for a few more weeks so I can't help with this.

Can anyone play around to see if it is possible to detect which
readline is installed?

Thanks,

Brian

Well one way to do this, although perhaps crude, would be to check to  
see if the libreadline is really a link to editline, since on a  
default Leopard install, it is:

[mvl ~]$ ls -l /usr/lib/libreadline.dylib
lrwxr-xr-x  1 root  wheel  15 Oct 17 15:59 /usr/lib/libreadline.dylib@  
-> libedit.2.dylib

I suppose one could also check for a "real" readline in "/usr/local",  
in case someone installed it.

-mvl

Ouch! I represent that remark!

OK, I've got my Leopard development system right here and I've got the  
Python 2.5.1/readline that we maintain for our science application.

print os.system("otool -L %s" % readline.__file__)
/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ 
lib-dynload/readline.so:

Edward's example of using EditLine syntax works for my "raw python"  
test:

$ python
 >>> import rlcompleter
 >>> import readline
 >>> readline.parse_and_bind ("bind ^I rl_complete")

 >>> readline.[TAB KEY PRESSED]
readline.__class__                    
readline.__class__                   readline.__class__
readline.__delattr__                  
readline.__delattr__                 readline.__dict__
...



BUT

If I change the IPython config file to use EditLine syntax, I get a  
segmentation fault when I start ipython.

$ diff .ipython/ipythonrc.0 .ipython/ipythonrc
395c395

Sorry, I misread your post. I meant that trying that with a readline module
compiled against GNU readline interferes with typing "b". So, unfortunately, you
can't just issue both commands hoping that the library will just ignore the
wrong one.

I'm not sure I understand yet.

I believe I have worked out the conditional logic to determine when  
we're linked against the libedit library versus GNU readline.

But from inside the python on Leopard - that uses libedit for its  
readline module - I can get tab-completion to WORK when I'm running  
python by using the EditLine syntax that Edward Moy suggested.

BUT from inside *ipython* I get a segmentation fault.


I was all set to add the code to the IPython ipylib.py  but I need to  
determine the cause of the segfault first.

I'm using IPython from subversion trunk with  {2007-10-28} as the SVN  
tag.


Thanks!

This "which python" is an important point, but it is NOT causing my  
segfault.

I'm using Apple's Python. I'm certain. For IPython.

If you add this code to iplib.py then you are able to determine if you  
are bound to libedit.

have_libedit - False
if sys.platform == 'darwin' and have_readline:
     import commands
     (status, result) = commands.getstatusoutput( "otool -L %s | grep  
libedit" % _rl.__file__ )
     if status == 0 and len(result) > 0:
         # we are bound to libedit - new in Leopard
         # _rl.parse_and_bind("bind ^I complete")
         print "Leopard libedit detected."
         have_libedit = True


And that's what I see on the output when I start up ipython:

$ ipython
Leopard libedit detected.
Python 2.5.1 (r251:54863, Oct  5 2007, 21:08:09)
Type "copyright", "credits" or "license" for more information.

IPython 0.8.2.svn.r2841 -- An enhanced Interactive Python.



The problem is to pass the "complete" method correctly to libedit.


In iplib.py, line 1342:

             # Configure readline according to user's prefs
             for rlcommand in self.rc.readline_parse_and_bind:
                 if rlcommand.startswith("tab"):
                     pass
                     if readline.have_libedit:
                         rlcommand = "bind ^I complete"
                 print rlcommand
                 readline.parse_and_bind(rlcommand)




The FIRST time I launch IPython after making this change, I get an  
"Invalid command" error from readline:

$ ipython
Leopard libedit detected.
bind ^I complete
bind: Invalid command `complete'.
"\C-l": possible-completions
set show-all-if-ambiguous on
"\C-o": tab-insert
"\M-i": "    "

"\C-k": kill-line
"\C-u": unix-line-discard
Python 2.5.1 (r251:54863, Oct  5 2007, 21:08:09)



And the modules are compiled as a side-effect.


AFTER the modules are compiled, I simply get a segfault:

In [1]: ^D
Do you really want to exit ([y]/n)?
galatea:~ bwaters$ ipython
Leopard libedit detected.
bind ^I complete
Segmentation fault




SO:

1) How do I form the bind commands for libedit? "EditLine" syntax
2) The segfault is a bug, methinks. I posted it as such.

The segfault was in binding to the "complete" command; it does not  
segfault (and seems to work) if I bind to "rl_complete" instead.

*However*, I am not sure that this is what IPython wants.
I am going to assume that rl_complete is the correct thing (at the  
moment) and that IPython maps the appropriate completer via  
readline.set_completer().


We have a couple of problems, though.

A) The commands that are included in the default ipythonrc use  
readline syntax, and every one of them must be mapped to EditLine syntax

B) Passing plausible values into Leopard's readline.parse_and_bind  
causes a segmentation fault. Sometimes. When it's compiled Python.

Problem B is a bug report to Apple and I don't know for sure that I'll  
be able to fix.



Problem A - what to do about EditLine syntax in general - may best be  
left to the new user prefs stuff. I don't know.

What I am doing at the moment is hard-coding the mapping of the tab- 
completion as a special case in IPython's rilneimpl.py

I don't like that, but it works.

Also -- and a path to a Better World -- you can check IPython's  
rpimpl.py for a "uses_libedit" boolean value.   We could add some  
logic in iplib.py that checks this value and reads an alternate  
ipythonrc in case we're running on Leopard. I get nauseous thinking  
about it.

Anyway.
