Hi, that patch does not apply to guix master. Could you rebase it? You can do that using git pull --rebase Then you can regenerate the patch via git format-patch -1 and send it to this bug report as version 2. Thanks! Other than that, I did a license review and that seems fine. Please do not add trailing newlines at the end of the file. Please also make sure to use ./pre-inst-env guix lint r-crochet in order to find out obvious problems with it, if any. In this case, guix lint warns that '[' and other code-like things should be enclosed in the texinfo tag @code instead, for example: @code{[}
