Hello, I use the Emacs compilation mode (M-x compile).
For example, the following "M-x compile RET guix build does-not-exist RET" would result to the following: --8<---------------cut here---------------start------------->8--- -*- mode: compilation; default-directory: "~/" -*- Compilation started at Wed Jan 17 19:18:57 guix build does-not-exist guix build: [1;31merror: [0m[1mdoes-not-exist[0m: unknown package Compilation exited abnormally with code 1 at Wed Jan 17 19:18:57 --8<---------------cut here---------------end--------------->8--- It is not only visually, but it actually breaks a feature of the mode, too. The unknown package error is not detected as an error by the mode. I also had a case where it detected warnings as errors. Could we check for ANSI compliance instead of assuming it's presence? -- Christian Miller
