Command-line info sees more stuff than Emacs info

Command-line info sees more stuff than Emacs info

[Luther Thompson]

The Emacs info-mode can't see all of the info files on my system. Most
notably, it doesn't see coreutils. The command-line info seems to see
everything just fine.

I'm running Trisquel+Guix. I use the info and coreutils that came with
Trisquel, while Emacs is installed with Guix.

I would expect both info and Emacs to use the same INFOPATH environment
variable. Here are the relevant lines from ~/.profile:

export INFOPATH=PATH
...
GUIX_PROFILE="$HOME/.guix-profile" ; source "$HOME/.guix-profile/etc/profile"

And the relevant line from ~/.guix-profile/etc/profile:

export INFOPATH="${GUIX_PROFILE:-/gnu/store/38lybr3lz7d2i1pqx9p025jiinxcpa8m-profile}/share/info${INFOPATH:+:}$INFOPATH"

Thanks for any help,
Luther

Most likely the problem is that ‘info’ from Trisquel looks for manuals
in /usr/share/info by default, where Emacs from Guix does not.

The fix is to add /usr/share/info to INFOPATH (and/or
‘Info-directory-list’ in Emacs.)

Could you check whether that solves the problem?

Changing INFOPATH does seem to work. I guess Emacs ignores the 'PATH'
component of INFOPATH.

On re-reading about the --directory option [0], I found that to add the
built-in default info directories, I just had to put this line:

export INFOPATH="$INFOPATH:"

...after running the Guix profile. This works for both the stand-alone
info and Emacs info.

Thanks for the help!
