Hi,
I use bash and, therefore, I have a rich .bashrc file that I share
among the few machines I work in. This rc file takes care of
identifying the machine and setting my environment accordingly.
I'm trying to figure out whether is possible in tramp or not to always
source my .bashrc file before attempting any command in the remote
machine. Is that possible at all?
I read the 'Remote shell setup hints' section in the manual, but it
does not seem to work for me. I have a .bash_profile file that sources
my .bashrc and I have no .profile in my home.
Any hints on this?
thanks,
Rodrigo

ooops, I'm just realizing that my environment (.bashrc) is actually
sourced. What happens is that PATH is set to something unexpected
which I suppose is a tramp default somehow:
/bin:/usr/bin:/usr/sbin:/usr/local/bin
That is, all seems to be working as described in the manual. I just
need to find out why is that my PATH is ovrwritten by the content
shown above.
sorry for the noise,
Rodrigo

Please check the Tramp manual, (info "(tramp)Remote Programs")

Hi Michael,
reading the manual does not seem to help me. Looking into tramp.el the
problem (my problem) seems to be that tramp does not respect whatever
my PATH is set to during the login process (in my case
within .bash_profile).
Perhaps there is in the lisp code of tramp-get-remote-path (used by
tramp-set-remote-path to actually set the path) something that I'm not
understanding. Too much lisp there for me.
On the other hand, if in tramp-set-remote-path I replace
"PATH=%s; export PATH"
by
"PATH=${PATH}:%s; export PATH"
then things start to work the way I want it! My PATH (crafted within
my .bash_profile) is now preserved and now I can actually compile.
Is there something I missed about how to configure tramp or does tramp
simply not work the way I want it?
thanks,
Rodrigo

Tramp has the variable tramp-remote-path. You can add there your
preferred paths, like
(add-to-list 'tramp-remote-path "/my/path" 'append)

Maybe the following works (not tested):
(add-to-list 'tramp-remote-path "${PATH}")

this is not convenient because different machines have different
paths. The logic for setting up those paths (based on the machine
name) is part of my remote bash_profile. Repeating that logic in my
local emacs configuration its simply not good.

This does not work because in tramp-get-remote-path the function delq
removes "${PATH}" from remote-path.

That's right. Tramp is not designed for that case. Maybe I shall
extend it this way ...

I don't understand. Do you mean this line:
(setq remote-path (delq 'tramp-default-remote-path remote-path)))
This deletes the *symbol* `tramp-default-remote-path', and nothing else.

I mean the code after the comment ";; Remove non-existing
directories.".
In general I find a bit too intrusive from tramp to go and do
something with my PATH in the remote machine. I would like the call to
tramp-set-remote-pat in tramp-open-connection-setup-interactive-shell
to be a choice left to the user. What do you think of the attached
patch?

I have committed a patch in Tramp CVS with a similar intention. If you
apply
(add-to-list 'tramp-remote-path 'tramp-own-remote-path)
after loading Tramp, your $PATH settings shall be preserved.
