ROOTQL ====== This is a Quick Look plugin that allows quick inspection of the content of ROOT files. Quick Look is available on MacOS X since version 10.5 (Leopard). To use QL select a file icon in the Finder and hit the space bar. For all file types supported by QL you will get a window showing the file content, for file types not supported you will get a generic window showing some basic file info. The idea of QL is that file content can be shown without the heavy application startup process. Generating a QL view of a ROOT file depends on the size of the file and number of keys, but generally it is a quick operation. Get the binary for the ROOTQL plugin from: ftp://root.cern.ch/root/ROOTQL.tgz To install the plugin, after untarring the above file, just drag the ROOTQL.qlgenerator icon to either /Library/QuickLook or to ~/Library/QuickLook. You may have to create that folder if it does not exist. Once installed you may have to refresh the QL plugin cache by executing: /usr/bin/qlmanage -r To build from source, get it from svn using: svn co http://root.cern.ch/svn/root/trunk/misc/rootql rootql Open the ROOTQL project in Xcode and click on "Build" (make sure the Active Build Configuration is set to "Release"). A command line short cut to open the Xcode project is to type "open ROOTQL.xcodeproj" in the Terminal app. Move the resulting plugin from the build/Release directory to either the /Library/QuickLook or ~/Library/QuickLook directory.
