I have this short snippet of code for a Guix related utility script and for the love of the Glowcloud it does not want to work. I want to filter stderr for certain lines and they are not being redirected. When running the full script from a shell, it correctly captures standard out, but all the warnings and errors from the subprocess and/or its children go directly to the terminal.
I looked in the Guix sources to see how others do it and found mention of a possibly related bug: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=52835 Is that still relevant? Because debuggs is just, khm, great, I don't see any clear indication of what its status is. (define (with-input-from-make thunk) (with-error-to-port (current-output-port) (lambda _ (with-input-from-port (open-pipe* OPEN_READ "make") thunk))))
