Answer 2

Answer for Windows (not Mac OS, but suddenly someone will come in handy or you decide to port):
1. Create the HKCR\[uri-schemename] key in the registry (for example, HKCR\myapp)
2. Write a description in the default string parameter (any , for example URL:My APP)
3. Create a URL Protocol string parameter without a value
4. Create the key HKCR\[uri-schemename]\DefaultIcon
5. Write the path to the icon file in the default string parameter, for example, C:\Program Files\My APP\MyApp.exe,0 (0 here is the index number of the icon in the file)
6. Create the key HKCR\[uri-schemename]\shell\open\command
7. Write the command to launch the application in the default string parameter " C:\Program Files\My APP\MyApp.exe" "%1" (%1 here are the passed command line attributes)
