clikeys

clikeys is a small program to interact with the macOS Text Input Sources (TIS) part of Carbon using Objective-C. TIS itself seems to be deprecated but I was unable to find any other library or framework available on macOS that allows you do interact with the system keyboard layouts in a similar way. With clikeys you can query, select, deselect, enable and disable keyboard input layouts, similar to how you'd do it through System Settings. Registering inputs is also possible but there seems to be no API exposed to deregister the inputs. AFAIK the only way to register an input without clikeys is to logout and log back in, which is kind of inconvenient.
