Hi, I'm trying to do some CoreText suff (10.5). Most of the calls are fine, but one fails: global name 'CTFontCreatePathForGlyph' is not defined Is there any way around this? Thanks -jt |

Which version of PyObjC do you use? I guess it's the one included in
Leopard, that seems to mis the symbol while PyObjC 2.2 does have it.
Adding a new function can be done using objc.loadBundleFunctions:
import objc
import CoreText
objc.loadBundleFunctions(CoreText.__bundle__, globals(), [
('CTFontCreatePathForGlyph',
'@@sn^{CGAffineTransform=ffffff}')
], False)
The code above (untested) should add 'CTFontCreatePathForGlyph' to the
globals dictionary.

It seems like some names can't be found. CoreText is one of them.
from CoreText import *
objc.loadBundleFunctions(CoreText.__bundle__, globals(), [
('CTFontCreatePathForGlyph', '@@sn^{CGAffineTransform=ffffff}')
], False)
Produces: NameError: name 'CoreText' is not defined
I tried manually loading the bundle as follows:
objc.loadBundle("CoreText", globals(),
bundle_path=objc.pathForFramework(u'/Developer/SDKs/MacOSX10.5.sdk/System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/CoreText.framework'))
Which also fails.

Hi,
James, import CoreText is missing there.
Cheers, Petr

Bah. Thanks. Still not quite out of the woods, though.
Now it's not having trouble finding the function
(CTFontCreatePathForGlyph), but I get a new error:
depythonifying 'short', got 'unicode' of 1
My usage is nearly identical to an example in cttests.py for obtaining
a font and getting the Glyph from it:
v, gl = CTFontGetGlyphsForCharacters(font, u'x', None, 1)
v = CTFontCreatePathForGlyph(font, gl[0], None)
This leads me to wonder if the signature mentioned previously for
CTFontCreatePathForGlyph was incorrect:
'@@sn^{CGAffineTransform=ffffff}'
Unfortunately, I can't find any documentation on how to map the
signatures. For someone that knows, is this signature correct?
Thanks

I should have mentioned that, the version of pyobjc that's included
with Leopard cannot do what you want it to do. You must pass
unichar(u'a')) instead of u'a'. The reason for that is that "unichar"
is an alias for "short int" in (Objective-)C, both result in the same
metadata.
The version of PyObjC that's in the subversion repository does know
the difference between "unichar" and "unsigned short" using hacks in
the metadata file.

The signature is correct. "s" is the encoding for both "short int" and
"unichar".

Ok, so in order to do this, I need to install the version in the trunk. I hate to say it, but that's causing me trouble as well... $ sudo easy_install pyobjc==2.2b1 Searching for pyobjc==2.2b1 ... Running pyobjc-2.2b1/setup.py -q bdist_egg --dist-dir /tmp/easy_install-_86MCZ/pyobjc-2.2b1/egg-dist-tmp-Q8jX-H The required version of setuptools (>=0.6c9) is not available, and can't be installed while this script is running. Please install a more recent version first, using 'easy_install -U setuptools'. (Currently using setuptools 0.6c7 (/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python)) error: Setup script exited with 2 $ sudo easy_install -U setuptools Searching for setuptools Reading http://pypi.python.org/simple/setuptools/ Best match: setuptools 0.6c9 Processing setuptools-0.6c9-py2.5.egg setuptools 0.6c9 is already the active version in easy-install.pth Installing easy_install script to /usr/local/bin Installing easy_install-2.5 script to /usr/local/bin Using /Library/Python/2.5/site-packages/setuptools-0.6c9-py2.5.egg Processing dependencies for setuptools Finished processing dependencies for setuptools $ sudo easy_install pyobjc==2.2b1 (Same as first try) Is there some config file that will allow me to get this to point to the right setuptools?

Phew, I'm glad that didn't work. Please don't install PyObjC 2.2 in the system install of Python. There are differences between the current edition of PyObjC and the version included in Leoopard and I don't know if those changes are backward compatible. That means that installing an updated version of PyObjC could break system components (especially on Leopard Server). Sadly enough the version in the trunk isn't ready to be installed by new users yet, I need to do some work on packaging (makeing sure that it can be installed from source with the Python.org distribution, provide binary packages, ...).

It is possible, I've been busy with other stuff and others don't seem
to feel qualified enough to anwser your question.
My current guess is that you have succeeded in partially installing
the latest version of PyObjC. Check you /Library/Python/2.5/site-
packages directory and remove all traces of pyobjc-2.2 in there
(pyobjc-core, pyobjc-framework-*). If you do that the ord('...)'
version should work.
If it doesn't you'll have to wait for a proper release of pyobjc 2.2.
