Does anyone know of any spotlight plugins that would extend spotlight searches to the content of an applescript?
I don’t know since I don’t have 10.4 installed yet, but I guess you could find the text importer and add .applescript files. Spotlight importers are assigned document types by listing the uniform type identifiers (UTIs) from which they extract data. The supported UTI types are specified in the importer’s Info.plist file that is contained within the plug-in bundle.
