What do you mean by “let the exception through”? It seems better to be
non-blocking and thus catch the exception then raise a meaningful
warning; it’s required when running with the option recursive.
Well, maybe an improvement could be in the addition of some
’report-git-warning’ and/or ’with-git-error-handling*’, in (guix git);
hum, I do not know.
Last, considering that the module (guix import go) already contains 4 UI
messages (G_), trying to move this warning about Git to (guix scripts
import go) will add some complexity – re-raise the exception 2 or 3
times, IIUC – and thus it will not change much about the UI, IMHO. I
mean, such move should be for all the messages or nothing.
Cheers,
simon
