Hello Guix! Here are a couple of new packages that extend mu4e, notably, mu4e-patch makes emails with patches look nice :-). As a side-note, I wasn't able to run `guix lint`: ~~~ $ ./pre-inst-env guix lint emacs-mu4e-patch Backtrace:macs-mu4e-patch@0.1.0-1.522da46 [refresh]... 9 (apply-smob/1 #) In ice-9/boot-9.scm: 705:2 8 (call-with-prompt _ _ #) In ice-9/eval.scm: 619:8 7 (_ #(#(#))) In guix/ui.scm: 1692:12 6 (run-guix-command _ . _) In srfi/srfi-1.scm: 640:9 5 (for-each # …) In guix/scripts/lint.scm: 57:4 4 (run-checkers _ _) In srfi/srfi-1.scm: 640:9 3 (for-each # …) In guix/scripts/lint.scm: 64:17 2 (_ _) In guix/lint.scm: 1010:2 1 (check-for-updates #) In ice-9/boot-9.scm: 829:9 0 (catch srfi-34 # …) ice-9/boot-9.scm:829:9: In procedure catch: Wrong type (expecting array): () ~~~ Does this ring any bells? Hopefully there isn't anything wrong the with the attached emacs-mu4e-patch package definition. Thanks, Pierre
