Mousetrap is a tiny go library that answers a single question: on a windows machine, was the process invoked by someone double clicking on the executable file while browsing in explorer?

motivation: windows users unfamiliar with command line tools will often "double-click" the executable for a tool. because most cli tools print the help and then exit when invoked without arguments, this is often very frustrating for those users.

mousetrap provides a way to detect these invocations so that you can provide more helpful behavior and instructions on how to run the cli tool.
