Hi Jasper,
When I do a quick look on a TextMate text document, I just see a big TextMate icon and not the content. Does anyone have an idea how that could be fixed? Is it a Mac OS problem for not showing the content of a text file or is the OS simply asking the app (TextMate) how the document should be shown somehow?
I was able to hack together something that works on my machine, based on the comments here and some docs at Apple: http://developer.apple.com/macosx/uniformtypeidentifiers.html. Note that there are probably *WAY* more intelligent ways to do this, and if you implement what I suggest here you are doing so AT YOUR OWN RISK. :-)
Now, with that out of the way, I just created an empty application (from the shell) with a hacked Info.plist, as follows:
/Applications/TypeMapper.app/ Contents/ Info.plist
In Info.plist I put the following: =========================================================== <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleDevelopmentRegion</key> <string>English</string> <key>CFBundleExecutable</key> <string>TypeMapper</string> <key>CFBundleVersion</key> <string>1436</string> <key>LSMinimumSystemVersion</key> <string>10.3.9</string> <key>NSAppleScriptEnabled</key> <string>NO</string> <key>NSMainNibFile</key> <string>MainMenu</string> <key>NSPrincipalClass</key> <string>OakApplication</string> <key>UTExportedTypeDeclarations</key> <array> <dict> <key>UTTypeIdentifier</key> <string>org.blah.LaTex</string>
<key>UTTypeDescription</key> <string>LaTex</string>
<key>UTTypeConformsTo</key> <array> <string>public.plain-text</string> </array>
<key>UTTypeTagSpecification</key> <dict> <key>public.filename-extension</key> <array> <string>tex</string> </array> </dict> </dict> </array> </dict> </plist> ==================================================
The important stuff in there is the UTType stuff. Just adjust/copy that "dict" section with fake data about the file type you want to use with QuickLook. As long as UTTypeConformsTo is public.plain-text, QuickLook will display it as text.
And if someone else knows how to do this properly, please let me know. :-)
