Keywords <=> Variables in appscript
by Adam Morris May 5, 2010

May 5, 2010

How can one refer to keywords (the k) given a variable? I'm working on a script that allows users to tell pages, for example, to set the current selection's properties to stroke type: solid, stroke width: 1.0. But I want to abstract all of this away. Coercion is simple enough, but what to do about defined keywords when given a string?

Error while trying to install pyobjc2.2b on SL 10.6.3

Hi all, Recently I had to upgrade to Python 2.6.5 for an issue reported by one of my users and as I had done in the past installed a custom install of Python 2.6.5 (which I ship with the app). Everything went smooth but while installing PyObjc 2.2b itself I got the following error: ironman:temp arif$ easy_install pyobjc==2.2b2 Searching for pyobjc==2.2b2 </snip> Running pyobjc-framework-SystemConfiguration-2.2b2/setup.py -q bdist_egg --dist-dir /var/folders/nw/nwn2NyaOHmKGsqzdPdzbm++++TI/-Tmp-/easy_install-yDhfjL/pyobjc-framework-SystemConfiguration-2.2b2/egg-dist-tmp-cWmDsY <built-in>:0: warning: Mac OS X version 10.5 or later is needed for use of the new objc abi Modules/_manual.m: In function ‘mod_SCDynamicStoreCreate’: Modules/_manual.m:228: error: Mac OS X version 10.5 or later is needed for zerocost-exceptions error: Setup script exited with error: command 'gcc' failed with exit status 1 This is 10.6.3 Mac OS X Server VM running on VMWare Fusion. Appreciate any pointers in the right direction. Thanks, Arif

Doesn't look like it. System Events declares the property's type as 'list [of references]'. (Compare with Finder's 'entire contents' property, which is declared as 'reference'.) So you have to retrieve the entire list before you can do anything with it. > b) The same operation on the resultant list on Snow Leopard (10.6.3) > seems to run 4x slower than on Leopard (10.5.8), discounting hardware > differences. Is there a way for me to setup the appscript > installation to mitigate this performance hit? Have you tried running 32-bit on both to see if it's a 32-/64-bit issue? Otherwise, I'm guessing any performance hit will be in OS X/System Events, though you'd need to profile your code to be sure.
