OS X and iOS use .strings files for localized text strings as described in the String Resources Documentation:
Resource files that contain localizable strings are referred to as strings files because of their filename extension, which is .strings.
It is yet annoying that OS X and Xcode don’t provide a built-in QuickLook plugin for previewing .strings files. When you preview such a file in QuickLook you see this window:
To solve this issue, here is a simple QuickLook plugin called ‘StringsFile’ that lets you preview .strings files (plain text .strings and binary property plist .strings).
This QuickLook plugin is really useful to quickly check the content of a .strings file. When you preview such a file, you will now see:
A precompiled version can be downloaded here: StringsFile.qlgenerator.zip
You can download the source code here : Download ‘StringsFile’ Source Code
- Download the precompiled version
- Copy the file into /Library/QuickLook/ or ~/Library/QuickLook/
- Execute the command
qlmanage -rin the Terminal - or restart the machine
Update (02.04.2014): The plugin has been updated to also generate a thumbnail for .strings files.
