$ ttyper --list-languages
thread 'main' panicked at 'Couldn't get installed languages under config directory.: Os { code: 2, kind: NotFound, message: "No such file or directory" }', src/main.rs:219:14
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

The error disappears once I create $HOME/.config/ttyper/language .

My expectation, in order of preference:

• No error. Just display an empty list because no languages are installed (or just the included ones, see --list-languages should also list included languages #54 )
• A more user friendly error that explains what directory to create
