Hi Andy! Thanks for the hard work, this is pretty elegant indeed! Question: do we need both "out" and "lib" outputs? My understanding is that "lib" is useful when one wants to start the program from a REPL. Correct? > I wasn't able to really test whether or not it works - it throws an > exception whenever I press a key. Same here. It does not do that when built manually with Quicklisp. Although I recall seeing something similar when building manually with the wrong arguments. I also suspect that some CFFI dependency (gtk?) is not packaged correctly and some paths are missing. I'll look into it. -- Pierre Neidhardt https://ambrevar.xyz/
