Vapor Leaf Extension

Update: The Vapor Leaf Extension is now meant to be used with the Xcode Plugin I designed to provide Xcode language support for the Vapor Leaf language. The version for HTML syntax support only can be found in the dedicated branch.

Download and set up the Vapor Leaf Plugin for custom syntax highlighting and indentation for Leaf tags with HTML tags.

This Application registers Vapor Leaf’s .leaf file type to LaunchServices adding custom file icon for the file type inside Xcode and in the Finder. Download and run just once for desired result.



To create your own custom icon follow the Apple Developer Documentation: Design and implement macOS document icons

Important: Make sure to avoid registering the Document Type Identifier before you have your icon perfect. Once the file type is registered, it is very hard to reset. I had to rebuild my LaunchServices database using Onyx to reset it. Remove the document type preset in the project by deleting the “Document types” key from the project’s Info.plist.

Tips: LaunchServices is where the file association is stored. The association is easily unregistered while Document Type has not been registered. Once the Document Type was registered I found very hard to reset. Below are 2 command line code snippets that helped me while I was trying to design the icon.

View all LaunchServices associations: /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -dump

Command-F to search for file type, .leaf in this case. Once you find the path name for the project that registered this file type you can unregister it: /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -u
