bug#44272: guix edit doesn't work when $EDITOR is set to "kate"

[zimoun]

Dear Nathan,

Or Emacs. ;-)

Instead ’kate’ use ’--line/-l’ and not ’+N’.  You could wrap, something
along these lines:

--8<---------------cut here---------------start------------->8---
#!/bin/sh

kate -l $(echo "$*" | tr "+" " ")
--8<---------------cut here---------------end--------------->8---

then:

  export EDITOR=/path/to/kate-wrapper.sh
  guix edit emacs

works (with ’/path/to/kate-wrapper.sh’ executable).  Well, the wrapper
could be better, obviously. :-)

As Leo said, it does not seem a bug on the Guix side.  Well, what could
be done on the Guix side?  What do you suggest?


All the best,
simon
