Hi All,
Here's what I'd like to be doing - When I start emacs, I typically open up
multiple eshells to do different kinds of compilation etc. Is there a way
to retain the "session" in such a manner that all open eshells are also
retained.
As a workaround I was attempting to write a script that would open up the
necessary eshells -
(progn
(eshell)
(rename-buffer "b1")
(insert "cd path1\n")
(eshell)
(rename-buffer "b2")
(insert "cd path2\n")
)
The problem is that I am not able to cd into the right place in eshell
using (insert "cd path1\n") !!!
Regards,
Kashyap

Maybe the following could work, it seems to do what you want when I try
it here.
(progn
(let ((default-directory "path1"))
(eshell t)
(rename-buffer "b1"))
(let ((default-directory "path2"))
(eshell t)
(rename-buffer "b2")))
I don't know if using `default-directory' like that is such a great
idea, but it looks slightly better than the result of:
(progn
(eshell t)
(eshell/cd "path1")
(eshell-send-input)
(eshell t)
(eshell/cd "path2")
(eshell-send-input))

That seems to be because you don't use `eshell-send-input'
Hope it helps in some small way.

This is a working solution for me.

The above snippet does not seem to work for me. Could you please explain
the below lines ?
(eshell t) -> This opens up a new eshell
(eshell/cd "path1") - ?????
(eshell-send-input) - I am guessing the command in the previous step gets
passed on using this command.

Absolutely helps!!!

The `eshell/cd' function is what is executed when you type 'cd' into
eshell, unless you have changed this. It doesn't change what you see in
eshell though, so the `eshell-send-input' should send an empty command,
which resets the eshell prompt and should show you that it's actually in
the right directory. Perhaps I got it wrong here, I use `eshell-reset'
in one of my keybindings, but I though send-input was perhaps clearer to
use here, sorry.
It also doesn't rename the buffers, so it was wrong anyway, I only know
that just sending a `\n' character to an eshell buffer doesn't execute
the command, but `eshell-send-input' does, or should. At least that's
what I noticed when messing around with sending commands
programmatically.

Awesome!

Oh, I now get the use of (eshell-send-input) ... I can even do
(progn
(eshell t)
(insert "cd /Users/kck")
(eshell-send-input)
)

Kashyap
