Why build Python 2.7.1 from source?  Just download the 32-bit-only OS X 
installer from python.org.  See here:

http://www.python.org/download/releases/2.7.1/

At the moment for instructional purposes, I would strongly suggest only 
using the 32-bit installer on all versions of OS X from 10.3.9 through 
10.6 and avoiding the 64-bit installer as the latter has issues with 
Tkinter and IDLE.

Unfortunately, http://www.python.org/download/mac/ is rather old and in 
need of updating.

Hi,

I'm new to python/py2app. My original python script accepts arguments as such:

python merge.py -o outfile.txt - i infile1.txt infile2.txt

Once I create the .app from py2app using argv emulation this no longer works and I get the following feedback:

new-host:dist Ian$ merge -o outfile.txt -i infile1.txt infile2.txt
merge: unknown option: -o
merge: usage: merge [-AeEpqxX3] [-L lab [-L lab [-L lab]]] file1 file2 file3
merge: too many arguments

this is the setup.py that py2app generated automatically

"""
This is a setup.py script generated by py2applet

Usage:
    python setup.py py2app
"""

from setuptools import setup

APP = ['merge.py']
DATA_FILES = []
OPTIONS = {'argv_emulation': True}

setup(
    app=APP,
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
)

Any idea what I'm doing wrong? Thanks in advance!

You are undoubtedly running the system-supplied merge command 
(/usr/bin/merge) rather than your app.  In general, OS X apps, including 
those created with py2app, are designed to be "launched", for example 
from the Finder by clicking on their icon, rather than run from a 
command line.  You *can* launch apps from the command line, for 
instance, with the open command (see man 1 open), or by "going under the 
covers" into the app bundle and executing the main executable file 
inside it.  But if your intent is to just produce a command-line 
callable utility, then you probably don't want to be using py2app.  The 
more conventional cross-platform approach using python's Distutils 
should be fine.  Or if it's just a one-file script, add a shebang line 
to the file and make it executable:

$ cat mymerge
#!/usr/bin/env python
#
import ...

$ chmod 755 mymerge
$ ./mymerge -o ...

hi all,

i'm guessing that since there was never a 3.2 beta 2 build for osx 
released, and since it's the holiday season, and since 3.2 rc1 is due in 
just 4 days now, that beta 1 has been / will be simply skipped for osx...?

anyone know? or know if there will even be an rc1 build for osx released?

cheers,
stephen.

Yes, unfortunately, 3.2b2 has not appeared yet.  FWIW, the beta 1 
installer is still available here:

http://www.python.org/ftp/python/3.2/python-3.2b1-macosx10.3.dmg

I'm sure there will be an rc1 installer.

Subject: [Pythonmac-SIG] py2app looking for ae.so in the wrong place
Message-ID: <20110104032709.GA1255@illinois.edu>

I finally upgraded my iMac from 10.5 to 10.6 and tried to recompile
one of my py2app apps with the system Python 2.6.1 and current py2app.

The application uses appscript, but for some reason it's trying to
import ae.so from /System:

% dist/StreamVision.app/Contents/MacOS/StreamVision
Traceback (most recent call last):
  File "/Users/nicholas/Documents/Development/StreamVision/dist/StreamVision.app/Contents/Resources/__boot__.py", line 31, in <module>

  File "/Users/nicholas/Documents/Development/StreamVision/dist/StreamVision.app/Contents/Resources/__boot__.py", line 28, in _run
    execfile(path, globals(), globals())
  File "/Users/nicholas/Documents/Development/StreamVision/dist/StreamVision.app/Contents/Resources/StreamVision.py", line 4, in <module>

ae.so is indeed in the app package:

% ls **/ae.so
dist/StreamVision.app/Contents/Resources/lib/python2.6/lib-dynload/aem/ae.so

Any ideas what's going on here?  Everything worked fine on 10.5 with
Python 2.5.

I want to sanitize some strings (e.g. escape apostrophes, spaces, etc.)
before passing them to the commandline via subprocess. Unfortunately I can't
seem to find any built-in function to do this. Am I really going to have to
write up my own sanitizer? Not that it'd be much effort, but I'd much rather
use an official function than risk forgetting something.

If it is for Bourne shell syntax, it's almost too simple to put in a
library: put into single quotes and replace all inner single quotes
with:

  '\''

You can play games with strings that are safe to not quote, etc but the
above is very simple and reliable. Something like (untested):

  "'"+s.replace("'", "'\\''")+"'"

A friend just pointed me to pipes.quote(). Is there any reason I shouldn't
just use that?

And given the number of rather simple things that are already in the
standard library (e.g. capitalize the first letter of a string), simplicity
isn't really an excuse for excluding this functionality. Especially since
doing this wrong leaves you open to security issues.

The subprocess doc show how to use shlex to parse a shell-like command 
string.  I'm not sure I understand your use case but is there a reason 
you can't use 'shell=False' and set up the arguments yourself, thus 
avoiding the need for escapes?  Even if you really need to have a shell 
execute the string, you should be able to set up the arguments and call 
the shell directly.

What I'm doing here is writing out a shell script for each of a list of
files I'm processing. The shell script has "hard-coded" paths in it
corresponding to the input file; subprocess is used solely to invoke the
shell script.

I recognize this is kind of a weird setup. It's mostly here so I can
delegate a chunk of functionality to be handled by a remote server queue --
just transfer the shell script over (as well as the input files), then run a
queue-submit program with the shell script as the argument. I can't do that
kind of thing just with subprocess.  The shell script approach also makes
some aspects of debugging more straightforward, but that's not why it's
here.

 It's a simple little app using tkinter.

 I'm using ActiveState's Python 3.1 if that makes a difference.

Python 3.1 strings don't have a decode method, so this is almost
certainly legacy code from Python 2.x that's trying to get from string to
unicode instead of going from bytes to string.

Python 3.1.2 (r312:79147, Mar 29 2010, 18:34:41) 
>>> ''.decode
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

>>> b''.decode
<built-in method decode of bytes object at 0xbb5399f8>

Any particular reason you're using 3.1 instead of 2.7?

Hi all,

Just to say that I plan to release py-appscript 1.0.0 final this month, 
so if you've noticed any bugs, inaccuracies, typos, stuff that doesn't 
quite make sense, etc. then please report it ASAP.

Also, new bug-fix releases of ASDictionary 0.13.1 and ASTranslate 0.5.1 
are now available that correct OS X 10.4 compatibility problems 
introduced in the previous releases. (Many thanks to Karsten Wolf for 
his assistance in fixing these.)

Thanks,

For anyone else who runs into a similar problem - I didn't get any
responses on this so I just uninstalled the current py2app and went
back to the 10.6-bundled version, which worked fine.

Hello,

I'm totally new to Python and having worked in a windows environment for
years and now my personal pc of choice is a mac.

Would someone be so kind as to walk me through installing python on a mac?

I don't want to use the newest version because the class that I'm trying to
get into uses 2.6 and 2.7 versions only.  So, I need that version installed
so I can do homework assignments, etc.

Many thanks,

John

Have you tried /usr/bin/python?  On Leopard (10.5.x) it is v 2.5.1.  If you
have Snow Leopard perhaps it's 2.6.something.

If that won't work for your needs, just download the Mac installer image for
2.7.1 appropriate to your version of OS X from this page:

    http://python.org/download/releases/2.7.1/

Once installed, locate the file (probably in ~/Downloads or something
similar) and double-click it to install in the usual manner.  I normally
just build from source (and don't bother with the framework stuff), so just
to confirm my instructions, I tried it out:

    * download
    * open the disk image (double click, use the "open" command from a shell
      prompt, etc)
    * open the corresponding volume which that mounts (named "Python 2.7.1")
    * double-click the Python.mpkg file to run the installer

The resulting binary is in

    /usr/local/bin/python (non-framework version)
    /usr/local/bin/pythonw (framework version)

I'm sure others more knowledgeable about Python-on-a-Mac will correct any
mistakes I've made.

That all looks right. Note also that the installer should have added it 
to your PATH, so if you type:

python

at a command prompt, you should get it.

Using the Python.org binary is a good idea, as you get an up to date 
version, can re-distribute binaries (via py2exe) if you want, and most 
third party packages provide binaries for it (of at all).

good luck!

To add some clarification to what everyone's already said: OSX comes with a
Python install by default, but it's not the latest and greatest. You can
make a secondary install using the disk image from python.org; this will
install alongside the standard Python install, so both are available.

Once you have installed a new python, you can go to the commandline and type
"which python". This will tell you the path to the Python executable you are
currently using whenever you type "python" on the commandline. If it isn't
the python you want, you can do "which -a python" to get a list of all of
your options. For example:

% which python
/usr/bin/python
% which -a python
/usr/bin/python
/usr/local/bin/python

This says that by default I will run the python in /usr/bin (which is the
default installed Python in OSX), but that there is another python in
/usr/local/bin which I can also run (which is the one that I installed
myself).

Good luck with your class!

-Chris

Message-ID: <981D0B4C9708CF41995970A0FD9B5DF2026C31935D@dlee06.ent.ti.com>

Hello

I have a script that installs Python, and then installs some modules with:

subprocess.call("python setup.py install")

The script works on Windows with py2exe, but gives me this error when using py2app:

File setup.py
    from distutils.core import setup
ImportError: No module named distutils.core

I tried explicitly including distutils when building the .app bundle, with python setup.py py2app --packages distutils (and several variations of --includes), but then I get this error:

error: invalid command 'install'

What do I need to do to make this work on mac?

Thanks!

Hello everyone,

I've been doing Python development on Windows for several years, and now I
will also be trying this on OSX.

After getting my Macbook Pro, I've updated the os/software, then tried
updating to Python 2.7.
No knowing there are so many places to get the core Python installer for
OSX, a friend had suggested that I install the Macports installer for 2.7
That installed fine, and I ran the command line that put that as the default
Python to execute.

I also use wxPython and want to continue developing wx apps on the Mac.
When I tried running the installer for wx, a message was displayed
indicating the postflight script had problems (I do have some info about the
specifics of that problem somewhere, but it's not handy at the moment).

So-my initial questions are...
   1. Why are there so many "variations" of the Python installer for the
Mac? (I'm not referring to 32-bit vs 64-bit architectures, although that
does complicate things quite a bit).

For example, there is the OSX installer at Python.org, then there are the
Macports python variations, and I recently read about something called
Macpython.

How does one know which o to use?


Thanks

Since I don't have any other specific needs at the moment other than
developing wxPython apps, I think I'd better go native, since wx attempts to
make the widgets look native.

Well, that's a good start, but I probably need to uninstall Macports, so I
can get wxPython installed to a working state.
And- I want to update the default python that came om my macbook pro to 2.7.
Should I do install that from Python.org?

Actually, while Fink uses a Unix-style shared library build, most other 
distributors including MacPorts, the Apple-supplied Pythons in OS X, and 
the ActiveState Pythons, use an OS X framework build based on the 
python.org builds.  The Tk on MacPorts is built as an X11 version by 
default but there is an Aqua port variant at well.  Unfortunately, the 
Aqua variant is broken on OS X 10.6 but there is hope that it will get 
unbroken now that ActiveState has started packaging a reliable version 
of the patched Cocoa-based Tk 8.5 which works in both 32- and 64-bit 
modes.

You left out a few! ?Why are there so many? ?History, varying needs, 
release schedules, because it's a fun thing to do - those are some of 
the reasons.  Here is my take on it.

Since at least Mac OS X 10.3 (7+ years ago), Apple has been including 
one or more versions of Python as part of OS X and over the years 
they've added more and more third-party Python packages and a few of 
their own Python add-ons. ?For many people's needs, the Apple versions 
are sufficient. ?On the other hand, like many operating system 
distributors, Apple tends to be very conservative about which versions 
it includes in major OS X releases, which tend to come out every two 
years or so, and they usually only supply security and some bug fixes in 
between major releases. For example, the current OS X release, 10.6.6, 
has Python 2.6.1 (released 2008-12) and 2.5.4 built in. ?At the moment, 
Python 2.7.1 and Python 3.1.3 are current. ?So, people looking for the 
latest and greatest Python releases usually have to look elsewhere.

Back in the old days prior to Mac OS X, there was a project to make 
Python available on its predecessor, Mac OS 9 (and earlier). ?That was 
known as MacPython and, in the early releases of Mac OS X, it continued 
to make releases for OS X. ?At some point, the MacPython project was 
merged into the standard Python Software Foundation (PSF or python.org) 
development and release process and installers for OS X begin being 
supplied as part of "official" releases of Python, rather than from a 
separate MacPython project. ?That's where we are today although there 
are still vestigial references to MacPython online.

One of the interesting characteristics of Mac OS X is that it combines 
technology from different origins and so it presents different faces to 
different kinds of users. ?A lot of stuff comes from its NeXT operating 
system heritage, a somewhat non-traditional Unix. ?When Apple decided to 
use it as the basis for Mac OS X, features were added to make the 
transition easier for users of traditional Mac OS. ?And more and more 
vanilla open-source products and features from modern Unix-y systems 
(like the BSDs and Linux) were incorporated. ?That shows up in Python in 
a few ways, including two rather different ways of installing Python on 
OS X: a traditional shared library approach as is used on nearly all 
other Unix-style systems, and a unique-to-OSX "framework" install which 
is based on NeXT practices. ?Most distributors of OS X Pythons use the 
latter but not all.

Another feature of OS X, rarely seen elsewhere, is the ability to have 
executable code for multiple architectures "glued" together into one 
file, a so-called universal file. ?That allows Apple to distribute one 
set of executable files and libraries that can support current and 
previous architectures. That was used to ease the big transition from 
PPC to Intel CPUs and, more recently, from 32-bit Intel to 64-bit Intel.  
It allows for a lot of flexibility and backwards compatibility but at 
the cost of added complexity for third-party languages like Python. ?So 
some of the reasons for different Python installers have been because of 
what architectures are supported and differing approaches to backwards 
compatibility (like how many OS X releases to support with one version).

Another reason: while Apple supplies a lot of open source software as 
part of OS X, it doesn't supply everything. ?One common reason is 
because of licensing issues (avoiding GPL libraries, for example).  
Also, Apple does not supply a package manager for its software, like 
those developed over the years for other open source systems. ?There 
have been at least three projects that have evolved to address that: 
Fink which provides many of the Debian/Ubuntu packages for OS X (without 
the Linux kernel of course); MacPorts (previously known as DarwinPorts) 
which provides the FreeBSD package ports; and, more recently, HomeBrew 
which has its own way of managing packages. ?All three provide Python 
ports and the associated infrastructure. ?And that can be very useful on 
Mac OS X when you want to install and run Python packages that depend on 
third-party libraries not included with OS X. ?Classic examples of those 
are the Python Imaging Library (PIL) and MySQLdb. ?Both require libs not 
included in OS X. You can build everything yourself but, for everything 
to work, you need to make sure that all the pieces are compatible, that 
is, built with compatible archs and deployment targets. ?A good package 
manager, like MacPorts or Fink, will eliminate the guess work and 
automatically build and install all the required dependencies in a 
compatible way so that it should all just work. ?That's probably the 
biggest reason for the popularity of installing Python from one of those 
distributors: it can be a huge time saver.

On the other hand, it is very difficult for volunteer-staffed projects, 
like most of these are, to keep on top of every package and keep them 
all up-to-date with optimal configuration selections. ?That's one of the 
reasons for commercial distributions, like ActiveState Python and the 
Enthought Python distribution, both of which build off of python.org 
configurations but add their own packages and offer paid support options 
on top of things. ?They also may target specific communities: EPD caters 
to the scientific / numeric user community.

Another complicating factor has been the way third-party Python packages 
have been made available. ?Over the past ten years are so, there have 
been a number of key improvements and growing standardization in Python 
packaging, first with Distutils and then later easy_install (setuptools) 
and now Distribute, Pip, and buildout to name a few. ?Not so long ago, 
it was much more difficult for users to install more complex packages 
especially those with C extension modules and so some projects 
distributed their own binary installers for various platforms including 
dependent libraries, like you've seen with wxPython. ?These days it is a 
lot easier to automatically build and install Python packages, however 
the problems associated with dependent libraries often remain (which is 
a strength of the MacPorts or Fink comprehensive solution approach).

So, all in all, there are lots of reasons plus others I'm forgetting.  
Many of them are not unique to the Mac world. ?But that doesn't make 
things less daunting when you first dive in.

Subject: [Pythonmac-SIG] Python 3.2rc1 available: new 10.6 IDLE and tkinter
	options
References: <4D329F55.9040903__48319.5588960827$1295195369$gmane$org@python.org>
Message-ID: <nad-BE31A4.00283917012011@dough.gmane.org>

The first release candidate of Python 3.2 is now available.  As with 
Python 2.7.1, two variants of Mac OS X installers are available for this 
release:  the traditional 32-bit-only installer that works on all 
machines supported by Mac OS X 10.3.9 through current 10.6.x ; and a new 
64-bit/32-bit installer for OS X 10.6.x systems.

Besides the operating system versions supported, one big difference 
between the two is in the versions of Tcl/Tk supported by IDLE and any 
other programs that use tkinter, the Tk GUI toolkit included in the 
Python standard library.  As in previous releases, the 32-bit-only 
installer will use the Apple-supplied TK 8.4 available in OS X 10.4, 
10.4, and 10.6, or, if installed, will use ActiveState Tk 8.4 (part of 
ActiveTcl).

Up until recently including at 2.7.1 release, the only standard 
available 64-bit-capable Aqua Tk version was the Cocoa Aqua 8.5 version 
shipped by Apple in OS X 10.6; however that has proven to be problematic 
when used with IDLE and other tkinter apps.  Recently, ActiveState has 
made available a newer version of Cocoa Aqua Tk (as of this writing, 
8.5.9) which seems to have solved  nearly all of the IDLE problems that 
have been reported when using Apple Tk 8.5.  The Python 3.2rc1 
64-/32-bit installer is the first python.org installer that supports 
using the new ActiveState 8.5.  It will still fall back to the Apple 
version but IDLE will issue a warning in that case. 

Which variant should you use?  For 10.5 and earlier, you can only use 
the 32-bit version.  If you are on 10.6 and want the simplest 
out-of-the-box experience, you may want to stick with the traditional 
32-bit-only installer.  Also, if you need to build applications (for 
example, with py2app) that need to also run on older OS X systems, you 
should use this version.   If you really do need 64-capabilities or if 
you would like to try out the improved GUI capabilities in Tk 8.5 and 
are willing and able to install the ActiveState Tcl/Tk 8.5, then you 
should consider installing the new variant.  If you need to use IDLE or 
tkinter but cannot install the ActiveState Tk 8.5, you should not use 
the 64-/32-bit variant with 10.6 at this time (10.6.6).

In either case, your testing and feedback is needed!  Please try out 
either or both versions and report any issues as soon as possible to the 
python bug tracker, http://bugs.python.org, as the final release of 3.2 
is less than a month away.

http://www.python.org/download/releases/3.2/

Also, along with the release is a new web page attempt at consolidating 
information about supported Python, Mac OS X, and Tcl/Tk releases.  It 
will be evolving up to and beyond the release.  Your comments (via the 
bug tracker) on it are also encouraged.

Hi Tony, 

>    1. Why are there so many "variations" of the Python installer for the Mac?


I think you'll find that the biggest difference between MacPorts python (and fink python) and most other builds (python.org for example), is that MacPorts uses X11 rather than Aqua (Apple's native window manager) and are not built as Apple 'Frameworks' - but rather regular shared libraries (more like with linux). 

Using fink and MacPorts help integration with many linux type apps (particularly helpful for scientific programming) whilst the native, Framework builds are better for native looking Macintosh apps - and the Apple bundled python is obviously native. 

This is a simple summary, and there are 101 more differences between all the builds - but I think the first decision you'll want to make is whether to go the Linux route, or go 'native' ;-)

hth,

I personally think that this would be the simplest solution - but other distributions do have their virtues and proponents. For example, Enthought takes the pain out of maintaining a good numpy / matplotlib installation and I find Activestate make building for distribution a pleasure. 

For now, stick with the python.org and then switching at any point is always simple - the folks here are always friendly and full of advice!

Happy coding,

My advice?  I've never had good luck trying to "update" the default
Python that comes with the Mac.  I'd recommend just leaving it alone and
using it, unless there's some reason you absolutely need 2.7.

It is safe to build (and run) a non-Framework build of other versions of
Python in various places on your Mac, but life gets complicated if you
attempt to "install" it.

I do want 2.7 because it's a requirement at work.
I want to have the same versions & packages to avoid compatibility issues.

I can put Python2.7 in a different directory and leave 2.6 there but I want
the 2.7 installation
to be the default one.

Default for you or default for the system?  It's easy to make it the default
for you.  Just make sure the installation directory appears in your PATH
ahead of /usr/bin.  I believe the installer does that by default.  I just
installed the 2.7 framework build the other day.  Now it appears ahead of my
other locations:

    % type -a python
    python is /Library/Frameworks/Python.framework/Versions/2.7/bin/python
    python is /Users/skip/local/bin/python
    python is /usr/local/bin/python
    python is /usr/bin/python

You almost certainly *don't* want it to replace /usr/bin/python.  That's
Apple's territory.  I don't know where Apple might put proprietary modules,
but it's somewhere in

    /System/Library/Frameworks/Python.framework/Versions/2.5

(on Leopard, at least).  If you were to overwrite /usr/bin/python you'd
deprive any system Python apps from modules they need.  In the
just-installed 2.7 I mentioned above I find 103 shared object files.  In the
above /System/.../2.5 directory I find 213.  My guess is that many of them
were put there by Apple.

Resist the temptation.  Make it your default, not the system default.

Did you build the app bundle with the Python that came with OSX, or did you
install a separate Python install from python.org and use that? You have to
do the latter; py2app's not allowed to include components of the operating
system in the apps it generates. Windows gets around this problem by not
having a standard Python install.

Do you have distutils installed? It usually doesn't come bundled with
Python. It can be installed with easy_install:

easy_install distutils

Try debugging this issue by printing sys.path, and check if
distutils/core... exists in one of them:

    subprocess.call('python -c "import sys; print((sys.prefix, sys.path))"')

Hi Sridhar

Your suggestion to debug this problem started me in the right path. I found a workaround for the issue.

First, I explicitly included distutils in my py2app bundle. With that, the error I get is:

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
    or: setup.py --help [cmd1 cmd2 ...]
    or: setup.py --help-commands
    or: setup.py cmd --help
    error: invalid command 'install'

I modified the included distutils files, and managed to get this stack trace

Traceback (most recent call last):
  File "distutils/dist.py", line 837, in get_command_class
    __import__ (module_name)
  File "distutils/command/install.py", line 21, in <module>
    from site import USER_BASE
cannot import name USER_BASE

The site.py included in the bundle has this comment: This is stripped down and customized for use in py2app applications

So apparently, py2app is removing USER_BASE and USER_SITE from site.py. I am not sure why it does that, but it is preventing the installation of modules with py2app.

I worked around it by modifying the included site.py to declare USER_BASE and USER_SITE after generating the .app bundle.

I think this might be a bug in py2app, but would like to know your input on this.

Regards,

huh? Sure it does -- distutils has been standard in Python for many many 
years.

So that's not it.

Besides, if you can run it unbundled, you have the packages you need, 
the question is how to get them properly into the py2app bundle.

Bill -- I'm really curious what issues you've had -- I haven't tried to 
use Apple's Python is many years (OS-X 10.2, I think) -- and it used to 
be painful to do so. Since then I've stuck with the Python.org versions, 
and had no problems (at least none that would have been solved by using 
Apple's Python).

Here's my decision tree:

1) Do I do a bunch of unix-y command line stuff in general, and not want 
to develop OS-X GUIs?

if yes -- use Macports

if no:

Do I need/want a newer version than Apple provides?

if yes: python.org build

Do I need/want to use py2app to distribute my app(s)?

if yes: use the Python.org build

Do I want to use pre-build binaries of common hard-to-build packages?

if yes: use the python.org build.


You can see that most roads lead to the python.org builds.


That being said, to be clear:

You don't "upgrade" Apple's python. Rather, you install a new one 
alongside it, and use that for your work.

Again, I've never had a complication from an installed python.org build. 
You sure would if you put it in the same place as Apple's but the 
installers don't do that.

In general, there are issues around site-packages, paths, and other such
things.  I don't think you and I necessarily have much trouble with it,
but I tend to help others with Python on Macs, and they seem to get into
all kinds of trouble.  The best one I've found is one group who had
decided to upgrade their Leopard Python to 2.6.  They'd installed the
python.org Python, removed the symlink /usr/bin/python, and re-linked
/usr/bin/python to the 2.6 version.  They were happy, but plagued by odd
problems with their machines that didn't (to them) seem to be
Python-related.

Another problem I've run into more than once was that the user had
installed different incompatible versions of an extension, and couldn't
see why an application (with an embedded Python interpreter) was
misbehaving -- it was getting the wrong version of the extension.

Not sure this is much use to anyone, but here's my decision tree, which
has worked well for me over the past 7 years:

> 1) Do I do a bunch of unix-y command line stuff in general, and not
> want to develop OS-X GUIs?

if yes -- use system Python.

if no:
 
> Do I need/want a newer version than Apple provides?

if yes: build non-framework version from source.

> Do I need/want to use py2app to distribute my app(s)?

Never happens.

Do I want to use pre-build binaries of common hard-to-build packages?

if yes: cry about the general unfairness of the world, then build them
from source instead to work with the system Python.

I don't think it's a bug -- you may have some problems with this. I'm 
not sure I quite get what distutils is doing with USER_BASE and 
USER_SITE, but I suspect that they are using them to figure out where to 
install stuff. That should be a function of the python you are 
installing to. A py2app bundle isn't usually installing stuff into itself.

How are you using distutils in this case? Are you installing stuff into 
the app bundle? Or into a system python? If a system python, you should 
probably use the system python's distutils (and thus its site.py) to do 
the work.

If you are installing into the app bundle (cool idea!), then you'll need 
to make sure that USER_BASE and USER_SITE are set correctly at run time 
for where the user happens to have put the py2app bundle.

For the purposes you actually mean, the python.org install does become 
the default one -- you can install it so that it comes earlier on your 
path (and I believe even this step is automated). In this case, all 
packages installed at the command line (or by binary installers) are in 
place for this build. I have not found an advantage to the fink or 
macports installs in the last few versions of Python versions.

But it's crucial to leave the Apple-installed build exactly where it is, 
as it is used by the system.

OK -- well, I'd say the solution to that is simple: DON'T DO THAT. We 
say time and time again that you should NEVER mess with Apple's python.

So there problem was not that they installed another python, but that 
they broke Apple's. And there is no need -- they got too smart for their 
own good. The python.org installer changes the users PATH anyway. 
(granted, not for all users, but if you have a multi user system, you'll 
need to know how to manage PATHs anyway -- and /usr/local should be on 
everyone's PATH)

Well, Even Apple supplies more than one version these days -- if you are 
embedding Python, you're going to need to know what you are doing.

well, I meant a bunch of unix-y stuff in addition to Python -- stuff 
that Apple doesn't give you -- I use MacPorts for a bunch of 
command-line scientific tools, and it would make some sense to use 
macports python for those things, too (dependencies and all).

But yes, if you are doing command line stuff and don't need anything 
Apples doesn't give you -- the Apple python is fine (unless you need a 
newer version)

I can hardly see this as easier/more reliable than installing the 
python.org build -- if you build from source and overwrite 
/usr/bin/python, you'll sure get the same problems! And anyone that can 
build from source understand PATHs, etc, enough not to screw things up!

fair enough.

Why cry when wxPython, PIL, SciPy, Matplotlib, ??? are available as 
nifty easy to use installers?

There really aren't very many people for whom "build it from source" is 
the best option.


Final NOTE: It's great that Bill takes this approach -- he's gotten 
things working and helped others a lot -- someone's got to build from 
source! Thanks, Bill!

Just to repeat for emphasis: NEVER mess with ANYONE'S system python.
Doesn't matter whether it's Mac, Windows (yes, some Windows machines
ship with a system Python for internal utilities), or Linux.  If you
don't like the system Python, your Python should be installed somewhere
else, with your PATH (and/or aliases) adjusted to grab it.

But this is where Bill J's use-case departs drastically from those of many
users, perhaps most, and certainly the majority of those who need any help.

If you think of Python as yet another handy scripting language, easier to
use than Perl, etc., then you don't care about making apps -- and 60% of the
questions that come to this site are irrelevant, because you're somebody who
already lives inside Darwin/Unix/whatever.

But there are a lot of people who do programming just in order to make user
applications, not to tweak systems from half-inside.  Many of them want to
make cross-platform programs (which scripting geeks never do).  Many of them
-- me for a ready example -- know barely enough about bash to get things
installed properly.  More to the point: *all* of them, if they want to use
Python (because they're sensible people) on the Mac (because they're
sensible people) need to use py2app.

Despite what's sometimes implied here, py2app is not a frill.  From my point
of view, it's essential to the Python community on Mac  -- perhaps a
minority point of view, but representing a minority that I suggest is
crucial to the future of Python and the Mac.

I'm not sure about majority -- who knows, really?

I agree. It's a really key tool.

One of the great things about Python is that it is suitable for:

Quickie command line scripting

Gluing larger systems together

Full on application development:
  - web apps
  - command line apps
  - GUI apps.

And on the Mac, you can:
  - build "native" apps with PyObjC
  - build cross-platform GUIs with wx or QT
  - build Unix-y apps with pyGTK
  - drive other apps with AppScript

Essentially ANY kind of development short of device drivers.

Is there ANY other language you can do all that with? (Ruby, maybe?)

So while py2app may not be "essential to the Python community on Mac", 
it IS essential to a fair fraction of that community, and I think that 
fact that you can do all these kinds of development with the same tool 
strengthens its position for the other purposes as well.

> and certainly the majority of those who need any help.

I think that's key -- Bill's approach is fine one for some users, but 
not what I"d recommend to newbies that aren't sure how to set a PATH.

The fact that there are a lot of ways to install Python on the Mac has 
really been a pain for the community to support (and pretty ironic, 
considering how the Mac platform usually is!). I'm not sure there is 
much that can be done about it, but one thing we have mostly done is try 
to use this list to declare the python.org builds as the "official" ones 
and try to get third party projects to build binaries for them

If you need help with macports, ask on a macports list, etc.

If I want to share my work with other users, and that work is not itself a
library, then as I see it I have two options: distribute either as a
collection of Python modules and any resource files, or as a packaged app.
The former is just about strictly worse than the latter from a usability
standpoint: the user has to install Python and any libraries I depend on
themselves, and then they have to invoke Python on my main module to use my
code (or else I have to use a shebang line that assumes they've installed
Python in a particular place), which in turn may well require using the
command line.

In short, if you are coding for other people who are not themselves
programmers and who use OSX, then you want py2app.

Hmmm.  My experience is that those are exactly the folks who get into
trouble by using the python.org installer on their macs -- those who
don't understand how PATH influences their usage experience.

Yep.

By the way, Python is more than "just another good scripting language".
I build large systems with it.  I do (rarely) write Mac "applications"
with Python.  I use Xcode and Cocoa-Python, and IMO it works great.  Is
that using py2app "under the covers"?  This is another reason not to
install a non-system Python; it sometimes screws up apps built using
Xcode and Python.

I am trying to install modules into the system python.

The problem with my solution (which I hadn't notice); is that modules are getting installed into the .app bundle instead.

The problem is that, even though subprocess.call("python setup.py install") picks up the system python (sys.executable has the expected value), it still loads the modules from the site-packages.zip in the .app bundle.

How can I make this new python process load the modules from system site-packages folder?

Thanks

I don't think it's a bug -- you may have some problems with this. I'm 
not sure I quite get what distutils is doing with USER_BASE and 
USER_SITE, but I suspect that they are using them to figure out where to 
install stuff. That should be a function of the python you are 
installing to. A py2app bundle isn't usually installing stuff into itself.

How are you using distutils in this case? Are you installing stuff into 
the app bundle? Or into a system python? If a system python, you should 
probably use the system python's distutils (and thus its site.py) to do 
the work.

If you are installing into the app bundle (cool idea!), then you'll need 
to make sure that USER_BASE and USER_SITE are set correctly at run time 
for where the user happens to have put the py2app bundle.

I definitely agree with this.  Py2app lets my self-contained Python
apps conform to the platform norm that users are expecting.  In that
respect it's along the lines of py2exe (plus something like InnoSetup)
on Windows letting me match those user's expectations with a single
binary installer (exe or msi) that they can just run.

For my Mac users, they want a DMG that contains the app to drag to
Applications, or the mpkg to do the installation for them.  So pretty
much anything I'm going to supply them is going to use py2app first,
then get packaged (optionally with PackageMaker) into a DMG through
hdiutil.

It also has the added benefit of having absolutely no dependence on
their local environment, aside from core OSX system libraries.

I suspect that you are getting environment variables set by py2app, 
rather that the user's raw environment.

Maybe it shouldn't be a subprocess -- what happens if you do a simple:

os.system("python setup.py install")

  you also may need to make sure the working dir is correct:

os.system("cd the/full/path/to/setup; python setup.py install)

Is that experience recent? The python.org installer got smarter at some 
point and started putting itself on the path, eliminating the need for 
users to do anything to their startup configuration files.

It just works, and in my experience it works well.

This python development convo has been by far the most informative so
far. I'm coming at this from very much a hobbyist position. I'm a
teacher and I want one programming language that lets me solve my real
problems. I also want the same language to be able to do native Mac
stuff too, if I ever have the need. I also want it to be a mature and
thriving language, something, frankly, that would be noticed on my CV.
And I want all of those things to be the same programming language
because I don't have time to invest in learning how to actively use
others.

That to me, is what Python embodies.

But I'm still confused on some major points on what it offers.

I'm trying really hard to unpack this. I can't use XCode and the
py-objc bridge with my "installed" python 2.7 setup? (Installed isn't
quite the right word, I know.) Why not? I guess it's because something
is hard-coded somewhere ...

I don't particularly "need" XCode but I really want to understand this.

Can't tell you how much I had read this conversation back, about a
year ago, when I first started learning Python. ...

I tend to build command-line tools and services.  But when I need to
build something with a Mac UI I pull up Xcode and use the Cocoa-Python
template.  Works like a charm -- but I believe it depends on the system
Python.  By the way, if you need to do this, take a look at Hillegass'
book, COCOA PROGRAMMING FOR MAC OS X.  And read Will Larson's great
series, starting with

http://lethain.com/entry/2008/aug/22/an-epic-introduction-to-pyobjc-and-cocoa/

Don't know, because I always use the "system" Python for non-Python-dev
coding.  But I'm betting there are some dependencies in Xcode or the
Xcode templates which require the system Python.

> Why not? I guess it's because something is hard-coded somewhere ...

Sure.  But anything hard-coded can be overridden.  The sources are just
sitting there...

> I don't particularly "need" XCode but I really want to understand this.

Unless you're developing just for the Mac, I'd suggest using PyGUI or
wxPython or PyGTK or some such, and build applications (small 'a') with
that, instead of Cocoa.

That experience will port out of the Mac to other Unices and Windows.

We shouldn't lose sight of the fact that the people we're talking about who
need to build Python programs as apps -- several of whom have responded here
-- don't typically want to confine those apps to the world of Macs.  Python
is a great language in which to build cross-platform (LOTS of platforms)
programs that will look native everywhere and run without any expertise on
the part of end users.  Since that makes an audience at least (at a guess)
20 times as big as the Mac-only audience, and (at a guess) 200 times as big
as the command-line-and-system-tools audience -- and since the future of a
language does depend on the size of its user base and not only on the savvy
and enthusiasm of its most expert users -- it would seem to be short-sighted
for anyone interested in Python on the Mac not to support py2app as fully as
possible.

You can certainly use pyObjC without XCode. I've never tried to do 
python development in XCode, from the little I've read here it never 
seemed to be well supported. Maybe someone here can tell you how to use 
XCode / pyObjC for app development.

Note that Apple has added a couple proprietary bits to its python 
install, maybe XCode relies on those.

I would love to hear more about what you can and can't do with XCode.

Note that if XCode has a way to build a self-contained App, and it uses 
Apple's system python, you are going to either get something that won't 
work on older systems, or you are going to be using an older python. You 
can't re-distribute Apple's python.

Also -- Apple has NEVER upgraded a python it delivered. Most of the bugs 
fixed between X.1 and X.5 versions of python are unlikely to bite you, 
but I had at least one that did -- when I found it, it had been fixed in 
the python.org release, but not in Apples -- and Apple has still not 
fixed it -- so I don't know what I'd have done if I'd be confined to 
Apple's python. Yes, I'm confined to Apple's OS - but at least they do 
update that!


And Bill's right -- if you want to support other platforms, wxPython or 
pyQT is the way to go. (pyGTK is so non-native on the Mac I wouldn't 
consider it, and I don't think pyGUI is very mature yet)

(the binaries for wxPython work with both the Apple and python.org 
builds -- 32 bit only for the moment)

You calling me short-sighted, Charles?

That's OK -- it's true, you know; I've been wearing thick glasses since
I was a kid :-).  But I don't know that it has much to do with py2app.
I think py2app is great, and I believe I even used it, once -- wanted to
make a Preference Pane with Python, and couldn't figure out how to do it
otherwise.

But in general I've not needed it -- I just use Xcode and the system
Python, and there's no need to bundle another Python with that approach.
I should probably figure out how to use py2app with that approach,
though; it might be more bullet-proof.

Oh, you should see my glasses.  Are you telling me py2app didn't cause
this???

My point was just that a lot of us can't use Python the way or you, or
aren't willing or likely to.  We're just application programmers, not
systems programmers.  And we also can't afford to code only for Mac.  I
write educational programs, and a lot of my (benighted) students persist in
using Windows.

And then, my more argumentative point was that Python needs us: we're the
ones who bring the wider attention and the critical mass.  Maybe I don't
understand how the support of programming languages works, but I know there
are beautiful languages out there orbiting lonely stars because people
admired them only from afar.

I'd be interested to know, if anyone knows: why DID Apple start including
Python?

Hello All,

I'm a complete novice to Python and I just created my first program for an
assignment in a Python class that I'm taking at the local community college.

The instructor didn't give us a book so, I'm trying to figure out one
important item.

How to run my program.  I know this is so basic for everyone but I just
started this class and this is my first exposure ever to this type of
environment.

I have an iMac, running python V2.6.1

My program is located in this directory:

File location: /Users/parkjv1/Birth_Month.py

When I open the terminal:

I'm presented with this info: cpe-66-75-97-27: ~parkjv1$

Is this my /users/parkjv1 directory?

When I type my file name Birth_Month.py I get an error indicating that
command not found.

So, where do I call my program so that it will run?

Thanks,

John

Hi John,


to run a python (.py) file, from the shell type :


python /path/to/your/file.py  (just drug'n'drop the file inside the terminal shell)

to know the directory where your shell is running type the command :

> pwd

it will show you the path.

to go inside the directory type :

> cd /path/to/the/directory

this [1] is a simple list of the bash commands in osx :

[1] http://ss64.com/osx/

and this [2] the standard python tutorial :

[2] http://docs.python.org/tutorial/

you can also try to buy a book about python that will help you to get started
there are a large number of book dedicated to python programming.

Thanks to all for your help.

I was able to successfully run my first program all be it was very simple.

I have ordered a Python for Dummies book from Amazon but it hasn't arrived
yet.  I think that will help initially until I get familiar with this
environment.

Thank you all for your information and empowering me to run my program.

Happy Python Programming to All!!

Message-ID: <3CDD4ED9-0E1E-4862-B1EC-8E2FEF091AF9@possibleworlds.com>

Hello all and thanks for listening!

I have scanned the archive and the web for current practices in packaging an Mac Python app with
py2app.  I have been successful before (i.e circa python 2.4 and Mac OS X 10.4).  I am now working
on under 10.6.6 and python 2.6.6.18 as shipped with the OS.  I am  using PyQt 4.8.2. as an i86_64
app.  It runs fine from the terminal as
	python Teatro.py


I used 
	easy_install-2.6 -U py2app which retrieved and installed py2app 0.5.2. 

I used a couple of variation of what seem to be standard procedure to create the
app including
	/Library/Frameworks/Python.framework/Versions/2.6/bin/py2applet --make-setup --alias --argv-emulation Teatro.py

followed by:
	python setup.py py2app
	python setup.py py2app -A

as well as
	/Library/Frameworks/Python.framework/Versions/2.6/bin/py2applet Teatro.py

the setup.py file looks like this:

"""
This is a setup.py script generated by py2applet

Usage:
    python setup.py py2app
"""

from setuptools import setup

APP = ['Teatro.py']
DATA_FILES = []
OPTIONS = {'alias': True, 'argv_emulation': True}

setup(
    app=APP,
    data_files=DATA_FILES,
    options={'py2app': OPTIONS},
    setup_requires=['py2app'],
)

when I try to run the app (Teatro.app or dist/Teatro depending on which procedure I used
to build it) i get this:

stripping saved 333408 bytes (8961700 / 9295108)

as the last line of the build and in the build directory i get
	dist.macosx-10.5-intel/

but away get the same result as above when I try to run the app



I am sure it is obvious what is wrong but I have reach a dead end.  

Any help would be appreciated

I eliminated the 1st of my problems by turning off argv_emulation.  That takes
care of the Evt.TickCount problem .  

But I am running afoul of the site-packages problem when I run the built app

I will repost as an new thread for clarity

I have seen various posts regarding this problem over the years but I flummoxed
by how I got here and what to do now that I am.

I am running MacOS X 10.6.6 I started out using the system python 2.6.  I built the
3d extensions (PyQt, numpy, PyOpenGL &c) and they are installed in 
	/Library/Python/2.6/site-packages

As I expected. My app runs fine when invoked directly from the Terminal.

Poor internet search results trying to locate and install py2app resulted
in the installation of ActiveStates pypm and Macports hg along with some
variants of easy_install. These missteps seem to have installed another
version of python 2.6 in the path of /Library/Frameworks/Python.framework
chain with it own site-packages folder. 

As a result  my installed 3d party extension were no longer found when starting
the app  from the Terminal.  Once I removed this framework. and the .local folder
created in my home folder.  I also removed the .profile file that was modified
(created) by one of the previous installs.  I discovered some installed put a
python in /usr/local/bin and removed it.

I tested my app from the Terminal and all was good again.  The sys.path variable 
prints the expected site-packages.

['/Users/mef/Development/-Applications-/Teatro',

After I run python setup.py py2app
I run dist/Teatro.app and the sys.path contents printed to the console looks like this:

What should I do here.  I think from what I have read I should NOT add a site-packages link in
/usr/lib/python2.6.  or is it that I mangled the installation of the system python somehow ?

Short answer (someone may come along with a longer one): use the
python.org installer.  If you use Python 2.7, pick the 32-bit version
unless you're absolutely certain ALL your users are on 10.6.

How should such an absolute path help in a py2app packaged app?

Your main issue here wasn't with Python, but with Terminal; you didn't know
how to use it to navigate your operating system and run files. You should
check out Massimo's links for more information on that stuff. Terminal is
basically like another version of the Finder: it can do everything the
graphical interface can do, but it does it by typing commands into the
command line instead of through the mouse and some keyboard shortcuts. Some
tasks are easier with the Finder; others are easier with the commandline. It
pays to be able to use both effectively.

(Terminal gives you a Unix-style command prompt, by the way, so the syntax
and many programs are the same if you're on OSX or Linux or Unix or BSD,
etc.)

Michael, I'm not sure what problem you are reporting?  But some of those
paths on sys.path look suspicious to me: "/usr/Extras/lib/python", for
instance.  Might want to look into how those got on your sys.path.

Also, in last week's discussion, we didn't really cover "setuptools" and
"easy_install", as they're not Mac-specific.  But, after years of
fighting with setuptools ("easy_install" is a part of that), trying to
get it to do what I need done, my advice would be to steer clear of
using it, as well.  It's not clear how it will interact with the other
package control systems you mention, such as MacPorts and pypm.

I suppose so -- but what's the point? If you want to have a program run 
only with a python install like yours, you don't need py2app...

It's still unclear to me what py2app is expected to be able to do with 
Apple's Python. but in practice, we generally use it with the python.org 
installer, as that gets you a fully independent app bundle.

In theory, you can build an app this way on 10.6, and it can run on 
10.3.9 and above.

In practice, all your user-installed packages have to be built for 
10.3.9 and above, too, and that is a bit tricky. However, most folks 
building binaries are trying to support that, so it certainly can work.

I don't know bout QT, though -- I don't use it.

If you want to continue with Apple's python, you might try:

1) adding the extra stuff in as required packages in your setup.py

or

2) writing some post-flight code into your setup.py that copies what you 
need into the app bundle --it's just a well-structured directory, after all.

good luck!

	(ActiveTcl 64-bit)
Message-ID: <4D38B531.8040100@activestate.com>

Hi,

Following 2.7 and 3.1, ActivePython 2.6 too is now updated to use 
ActiveTcl 8.5 64-bit on OSX.

-------- Original Message --------
From: Sridhar Ratnakumar <sridharr at activestate.com>
Subject: ANN: ActivePython 2.6.6.18 is now available
Date: Thu, 20 Jan 2011 14:18:11 -0800
To: python-announce-list at python.org, python-list at python.org

ActiveState is pleased to announce ActivePython 2.6.6.18, a complete,
ready-to-install binary distribution of Python 2.6. Among other updates,
this releases brings "postinstall" support to PyPM to facilitate
installation of modules such as PyIMSL.

     http://www.activestate.com/activepython/downloads

What's New in ActivePython-2.6.6.18
===================================

New Features & Upgrades
-----------------------

- Upgrade to Tcl/Tk 8.5.9 (`changes <http://wiki.tcl.tk/26961>`_)
- Security upgrade to openssl-0.9.8q
- [MacOSX] Tkinter now requires ActiveTcl 8.5 64-bit (not Apple's Tcl/Tk
8.5 on OSX)
- Upgrade to PyPM 1.3.0:

   - Programmatic use via ``pypm.cmd(['install', 'foo'])``
   - Support for postinstall and conditional user-notes

- Package updates:

   - pip-0.8.2


Noteworthy Changes & Bug Fixes
------------------------------

- [Windows 64-bit] `issue8275 <http://bugs.python.org/issue8275>`_: turn
off optimization for the ctypes module
- PyPM bug fixes:

   - Fix needless truncation of output when piping (eg: ``pypm list |
less``)
   - Respect download cache of ``*.pypm`` packages (don't redownload)
   - Bug #88882: Fix pickle incompatability (sqlite) on Python 3.x



What is ActivePython?
=====================

ActivePython is ActiveState's binary distribution of Python. Builds for
Windows, Mac OS X, Linux are made freely available. Solaris, HP-UX and
AIX builds, and access to older versions are available in ActivePython
Business, Enterprise and OEM editions:

     http://www.activestate.com/python

ActivePython includes the Python core and the many core extensions: zlib
and bzip2 for data compression, the Berkeley DB (bsddb) and SQLite
(sqlite3) database libraries, OpenSSL bindings for HTTPS support, the
Tix GUI widgets for Tkinter, ElementTree for XML processing, ctypes (on
supported platforms) for low-level library access, and others. The
Windows distribution ships with PyWin32 -- a suite of Windows tools
developed by Mark Hammond, including bindings to the Win32 API and
Windows COM.

ActivePython also includes a binary package manager for Python (PyPM)
that can be used to install packages much easily. For example:

   C:\>pypm install mysql-python
   [...]

   C:\>python
   >>> import MySQLdb
   >>>

See this page for full details:

     http://docs.activestate.com/activepython/2.6/whatsincluded.html

As well, ActivePython ships with a wealth of documentation for both new
and experienced Python programmers. In addition to the core Python docs,
ActivePython includes the "What's New in Python" series, "Dive into
Python", the Python FAQs & HOWTOs, and the Python Enhancement Proposals
(PEPs).

An online version of the docs can be found here:

Yes it is.

There are many different ways to do this, but for now I think the best idea would be to type

$ python Birth_Month.py

To tell the terminal that you want Python to run your program. 

I hope that helps, after the initial learning curve I think you'll find learning python and programming hugely rewarding! Good luck and stay in touch.

Subject: [Pythonmac-SIG] How to get a Mac OS X version of Tcl/Tk rather than
	X11 version.
Message-ID: <960836.10021.qm@web34405.mail.mud.yahoo.com>

I have an installation of Python 2.6.4 on my MacBook Pro (OS X 10.6) that by 
default uses X11 windows and dialogs rather than the Mac version of those GUI 
items.  In my googling and exchanges on other support groups I've come down to 
the problem may be with the Tcl/Tk installation using the "generic" X11 GUI 
rather than the Mac version.  Does anyone know how I can change that in the Tk 
part of the python framework?
 
I think this problem came up in the iPython email list, but I didn't get enough 
info from the messages there.
 
More Info:  The python framework is part of the SAGE package which I installed 
from source.  I did this on my Mac Pro (system 10.4) and it works well with Mac 
windows for matplotlib and Mac open/save dialogs for Tk calls.  But on my 
MacBook Pro I get X11 windows and dialogs.  I want the Mac versions.
 
Even more info:
 
If you're interested, below is the original message I put up on the SAGE support 
group and was told it's a problem with the type of Tcl/Tk installed. -- Lou 
Pecora,   my views are my own.
----------------------------------------------------------------------------------


I have an installation of SAGE (from source) on my Mac laptop in which using the 
tcl/tk library to plot (using TKAgg backend) or call tk file open/save dialogs 
calls the X11 versions and not the native Mac versions of dialogs and windows.  
I want to get the Mac versions.
 
I posted about this on this list recently and now after a response here and much 
googling I have the sense that the problem is that I have a SAGE package with an 
X11 version of the tk library rather than the Mac one. I compiled SAGE from 
source on my Mac laptop. That went perfectly.  I don't know how I got the X11 
version since I also compiled SAGE from source on my Mac desktop where the 
plotting and file dialogs are the correct Mac versions, not X11. The only 
difference is that the laptop is Mac OS X 10.6 and the desktop is 10.4.  If that 
matters, I don't know.
 
Does anyone know how to get the Mac version installed in the SAGE source-compile 
installation?  I have not found an answer to this elsewhere.  I'm hoping someone 
here knows how this is done with the source installation.
 
Thanks for any help or pointers.

Subject: [Pythonmac-SIG] Determining if I need an import
Message-ID: <AANLkTi=unEm1OJcR=2zL1HnW0KE3rdWN4SFtGZo1=Tbu@mail.gmail.com>

I've inherited a large codebase that is practically the definition of
"legacy", with all that entails. I've spent a lot of time removing unused
code, renaming variables, creating classes, moving global variables to
locals (let's stuff all our program state into a single module and then just
import that whenever we want to access it!), and so on, and now I want to
start cleaning up the dependency chains between different modules.

There's several places where I've had to move an import statement from being
at the top of the module to being inside a function right before it's used,
to prevent circular dependencies from causing imports to fail at program
start. I wouldn't be surprised if I've rendered many of these imports moot,
but short of a fair amount of painful grepping across ~20k lines of Python,
I don't know of an easy way to find them.

Is there a tool that examines your actual and apparent dependencies? I know
there are programs that will generate dependency graphs, but for those
there's little difference between a tight coupling and a single import
statement that isn't actually needed.

(Though if you'd care to recommend a dependency graph generator, I'd like to
hear about that too)

Thank you all for your attention to this matter.

I should clarify-  My apps are used in intense live animation production applications.

Having an app the runs like an app, can be executed from the dock and in all
aspects seems like a real Mac- app, for me, makes it possible to experiment with
new  models of media production. This is  my stock-and-trade. 

While --I --can  run the app as a python script and deal with the strange python
menu that shows up.  Not everyone can.  

In the heat of production having an bundled app w/ icons &c., makes our situation
much less stressful and much less prone to error. So,...py2app.  It looks like an  app, 
smells like app and, most importantly acts like an app. It  may be  a small  quality in
an app. but it is  a very  important  quality in an app for what I do. 

Adding insult to injury, I am constantly in development. So ... I am never ready to commit
(no pun intended). I need to fix things at a crucial moment. I need to add a  featur
 that no one anticipated.  I can't be rigid and orthodox here

py2app is 99.9 percent exactly what I need.  It it excellent and has been a terrific 
help to me a and to the the community.  I just got lost and frustrated in the
morass of development.

Using Apple's installed python means one less install and, one less opportunity
for problem.  It is probably shortsighted.  Given everything, installing a python.org
version of python might make things more consistent and easier.

Subject: [Pythonmac-SIG] C++ ABI 1002/102 incompatibility with wxPython
Message-ID: <4D3E95F8.5000101@etrix.com.au>

I have a wxPython app that is built with py2app.  A user recently
reported the following error when trying to run the app.

    Fatal Error: Mismatch between the program and library build versions
    detected.
    The library used 2.8 (no debug,Unicode,compiler with C++ ABI 1002,wx
    containers,compatible with 2.6),
    and your program used 2.8 (no debug,Unicode,compiler with C++ ABI
    102,wx containers,compatible with 2.6).
    Abort trap
    logout


It appears to be a difference in the wx libraries on the target system
and the wx libraries on the build system.

Unfortunately, at this stage, I do not know what the OS X version is on
the target system.

The app was built using Python 2.5.4, (wxPython 2.8.11.0 or 2.8.4.2 ??)
on OS X 10.6.6.

Is there anyway to fix this with a py2app setting ??

Doesn't py2app copy all the libraries to the app bundle ??  I guess that
doesn't guarantee that the libraries will load on any OS.

What about path settings ??

I presume others have solved this before.  Any suggestions ??

Many thanks,
Brendan.

That looks odd to me -- as far as I can see (did I miss something?) the 
only difference is ABI 102 vs ABI 1002 -- that almost looks like a typo.

I would ask on the wxPython list -- perhaps Robin will recognize those 
ABI numbers. And I"m not sure how to get those numbers at either run 
time or otherwise -- anyone know?

Meanwhile a couple questions/thoughts:

Is that the "apple's" python? i.e. the one in:

/System/Library/Frameworks/Python.framework/Versions/2.5

If so, that is likely your problem. py2app does not bundle up everything 
if you're using Apple's python, so your python install and your users 
may be different.

> Is there anyway to fix this with a py2app setting ??

not until we figure out what's wrong...

> Doesn't py2app copy all the libraries to the app bundle ??

it should, but it won't if you are using Apple's python, and sometimes 
things go wrong. wxPython puts itself in /usr/local/, while putting 
nifty sys.path manipulations in the python installs, so things can get a 
bit confused. But it's done so that one installer can support both 
python,org and apple pythons.

 > I guess that
 > doesn't guarantee that the libraries will load on any OS.

no, it doesn't, but it should load on any version that your supporting 
libs are built for -- the standard wxPython installers are built for 
10.4 and above (maybe 10.3.9 --not sure about that), and so is the 
python,org python -- are you using any other third-party libs that 
aren't pure python?

debugging suggestions:

  -- use the python.org python if you are not already.

  -- add a "print sys.path" in your app (before importing wx) -- then 
check the console to see what it prints, both in and out of an .app 
bundle - that should give you a clue -- if you can have your user report 
what they get -- that will be best.

  -- take a look in the generated app bundle -- it's just a directory -- 
you can see what's in there, and it will give you a clue.


> What about path settings ??

py2app should take care of that, but looking at sys.path will let you 
know if it's doing it "right"


HTH,

It's not a typo, the numbers indicate the C++ ABI (Application Binary
Interface) version the code uses. This defines stuff like how to call
functions, the stack layout, how to handle exceptions, etc. All pieces
of code in a program must use the same ABI version, otherwise those
pieces can't be used together.
The ABI version used by gcc has changed in the past which always means
that *every* code a program uses has to be recompiled with the new
compiler version.
As far as I know, version 1002 is still the current one and it was
introduced by gcc 3.4. Before that, the version was 102 (don't ask me
how these numbers are formed. I have to admit, it's a bit of an odd
numbering scheme...).
You can find out the ABI version a particular version of gcc uses by
running the following command:

g++ -E -dM - </dev/null|grep ABI

Here on my machine (gcc 4.0.1), this produces the line:

#define __GXX_ABI_VERSION 1002

So the above error message means that the wx libraries on the user's
system were compiled with a compiler that uses ABI 1002 (i.e. gcc >=3.4)
whereas the "program" contains parts that were built with a compiler
that uses ABI 102 (such as gcc <3.4).
But as mentioned above, it will only work when all components use the
same ABI.

Cheers,

It's that odd numbering scheme that threw me.

Any idea how to see what ABI version a given binary was compiled against?

Just to perhaps clarify one thing - the use of the python.org Python
is only an installation issue for the development machine.  py2app
will include the relevant portions of the python.org framework within
your application bundle, so it's not a requirement for any of your
users.  They'll still just see a single standalone application, which
just happens to have no dependencies on their system's python.

This can simplify things somewhat on the development machine too, since
you can use the python.org python installation (independent from the OS
version) on that machine for installing other third-party packages you
may need, again without affecting the system python.  Those packages
also get included in the final app bundle by py2app.

Hm, I don't know. The above only prints a preprocessor symbol, so that
one doesn't have to make it into the binary.
But I think that error message was specific to wx anyway (it was not a
generic error message from the linker, was it?), so maybe in general
that information is not recorded in the binary at all. Whenever I
experienced such an ABI mismatch before, it just resulted in a crash but
not in such an error message (but that always was on Linux, maybe OSX is
a bit different here...?).

I just saw in the docs that OSX 10.3.8 and earlier was using gcc 3.3.
The original poster said he's using 10.6.6, so couldn't it just be that
his user was using an old OSX 10.3 install and that's where the mismatch
comes from?
Anyway, I think there's two things to do: 1) ask that user what OSX
version he's running and 2) check all (C++) program dependencies where
they come from and what compiler was used to build them (if it was built
locally, check your build environment, otherwise check the documentation
that comes with the binary or ask the maintainers).

Cheers,

yep -- it really nice if you use the GUI for other parts of your process.

I use it that way too. I have a few apps that are under constant 
development (some mine, and the Peppy editor). I use Py2app to build an 
Alias bundle, and then I have an app that looks, feels and acts like an 
app, but actually runs the development code and my Python install. I 
can't give it to anyone else, but I can set up others with a similar 
python install and set them up the same way.

I'd think that what you are trying to do should work. And if you can

I think so -- and yes, it's one more install, but it's a pretty darn 
easy one.

It's that odd numbering scheme that threw me.

Any idea how to see what ABI version a given binary was compiled against?

Chris,

I thought otool could do that.  Try,

otool -L ABI

Do a

man otool

to see more.
Let me know if that works.

I use Eclipse/Aptana with PyDev, and if you manage to setup that  
monster, it shows unused imports (as well as unused variables etc.)  
quite nicely.
(It can't cope with dynamical class wizardry, like in dabo, and I  
don't understand why it fails to find Django classes.)

nope, can't find anything about ABI version in the man pages, and I've 
tried all the switches that looked like they might have something.

You'd think it would, though -- maybe I missed something.

pychecker is worth a try, too:

It'll likely find other stuff you want to know about as well.

Which Tcl/Tk is used by Python depends on the way the Python you are 
using was built.  The Apple-supplied Pythons in OS X and the Pythons 
installed from python.org and some 3rd-party suppliers (like ActiveState 
Python) use the "native" Aqua Tk, the most common versions being those 
shipped by Apple with OS X or the ActiveState Tcl/Tk distribution of OS 
X.  Python 2.6.4 is not the version shipped by Apple in 10.6 so you must 
have built or installed another version. `which python` will tell you 
where it is installed.   If the path starts with "/opt/local/" chances 
are you using a MacPorts Python; currently the MacPorts Python uses a 
MacPorts Tk port which by default is built with X11, rather than as a 
Aqua Tk.  The MacPorts Tk port does have a "+quartz" variant which is 
supposed to build Aqua Tk but it currently does not work on 10.6.

To get back to using an Aqua Tk, you can install the most recent 2.6 
Python (2.6.6) from python.org:

    http://www.python.org/download/releases/2.6.6/

It uses Aqua Tk 8.4 and is 32-bit only.  Note that 2.7.1 and 3.1.3 (soon 
to be 3.2) are the current versions of Python.

Ned Deily,


Thanks, Ned.  I found the solution to my particular problem.  

You are right.  I'm using the SAGE package which includes a full supply of 
python (numpy, scipy, Cython, etc.etc.). SAGE builds against the Apple Tcl/Tk 
Frameworks in /System/Library/Frameworks  *unless* there's another Tcl/Tk 
Framework in /Library/Frameworks.  I installed such a framework before running 
the SAGE install.  That's where SAGE python picked up the X11 GUI instead of the 
Aqua GUI in Tk calls. 

Solution:  Remove the /Library/Frameworks Tcl and Tk versions.  Then SAGE will 
build against the Apple Tcl and Tk frameworks.  And you see Tk dialogs and 
Windows in Aqua.

I got the hint from some helpful fellow to run otool -L _tkinter.so  on the 
_tkinter.so in down in the python /lib-dynload folder.  Doing that in Apple 
python and SAGE python pointed to different Tcl/Tk frameworks and helped solve 
the problem.  

I posted this separately on this list, too.

Hello there,
I am trying to run a python program on my Mac OS X Version 10.5.8. The

(pygtk) and on trying to install it using the "python setup.py install', I

I have tried in vain to look for the latter module(dsextras)... any one with

Message-ID: <AANLkTikW5dZGVnqjFfKyiKzZCfdJ4Ow=vvbCRL5dT--E@mail.gmail.com>

Hello,

I'm a new user of appscript, and I can't find a way to know when my computer
is sleeping or not.

with :

> from appscript import *

app("System Events").sleep()


I can force my system to sleep, but what I would like is to know when my
system is going to sleep, to launch some routines behind (like programming
an alarm to ring after 6 hours).
I searched for an argument who could tell me this, but didn't find any. Is
it at least possible ?

Thank you very much for your help
Best regards

I'm pretty sure not.

Applescript doesn't let you register callbacks within the system, and
even if you did something with a poll (endless repeat loop), the
repeat loop itself would prevent it from sleeping in the first place.

Ok so the only solution for me is to map a sleep key which will call my
program and plan some tasks (threading.Timer), and my program will force my
system to sleep after that.

Thank you Adam for your answer !

If you have downloaded Python 3.1.3 from the python.org website, try 
launching IDLE from a terminal shell window instead of double-clicking.  
In the shell, type:

/Library/Frameworks/Python.framework/Versions/3.1/bin/idle3.1

If it fails, there should be a traceback printed which may give a clue 
as to the problem.  If it does not, then quit IDLE and launch by 
double-clicking on IDLE.app in the Finder.  You will then need to look 
in the system.log to see any error messages if IDLE fails to launch.  
The Console.app in /Applications/Utilities makes that easy to do.

One recently reported problem with IDLE 3.x is that it can crash if its 
Recent Files list contains files with non-ascii characters in their path 
names.  That can happen if you were using IDLE 2.x with such files, 
where this is no problem.  A workaround is to simply delete the recent 
file list before launching IDLE 3.x:

  rm ~/.idlerc/recent-files.lst

The problem and a fix for it is here:
