Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
The emacs mode for Lean (which doesn't appear to be packaged yet, but
of course works via MELPA etc.) expects some sort of root directory for
Lean, which is not given simply because binaries and other files are
put into separate directories. This of course makes Lean impossible to
use as intended. However, I'm not quite sure how this would be fixed in
practice, as I'm not aware of any suitable directory hierarchy in such
a case.
Any ideas?

Cc'ing Amin Bandali, who took care of packaging Lean. I am happy to help
too, but I want to see what he says first.

When writing the package definition for the Emacs Lead mode, the code
could be rewritten to refer to the absolute path of the files/programs
it uses from the Lean project, by patching it with `substitute*' uses,
for example.
If that is not easy to do, another idea would be to create some kind of
overlay directory which would flatly collect all the items needed then
refer to that (the items would be symlinked to their real location).
See the `union-build' procedure of the (guix build union) module of
Guix.
HTH!

Hello Maxim,
thanks for your response! The second idea is basically what I had in
mind, as the Lean mode seems to depend on an actual file tree. Patching
the emacs mode however looks quite simple, as all one needed to do is
change the definition of lean-get-executable as defined in
https://raw.githubusercontent.com/leanprover/lean-mode/master/lean-util.el
. I might take a closer look and write a simple patch at some point,
but up to that point, it appears that just using ~/.guix-profile as a
root directory works as well, or at least doesn't raise any errors when
type checking etc.
Again, thanks for feedback!
