Eshell help.

Eshell help.

[Steven Wu]

I looked into eshell, and felt that I really like it. Unfortunately, I 
wasn't able to find much documentation about it. Here is a question that 
I found: if I redefine eshell-prompt-function to something I like, i.e. 
no pathname, then completetion doesn't work. I kinda like to have the 
pathname printed on the window title bar, not at the prompt. Also, if I 
want to do shell programming, where can I find the elisp primitives?

thanks.

Although I am in no way qualified to answer your LISP quesions, if you
want a fully functional shell try: M-x term

Eshell is worth investigating. U'll have to browse the source, but it's less
of a pain than u probably think.

I followed your suggestion and tryied to use M-x term, I had my shell 
working quit soon but, just after ther first 'ls' command emacs crashed 
immedialty, blocked without any life sign :)

Do you have to do anything special, apart from just typing M-x term
RET and then confirming Emacs suggestion of /bin/bash with RET?

Does Emacs really crash or does term just slurp all your keyboard
input?  Does C-c C-c do anything?  What if you have one Emacs with two
frames and you run term in one frame; does the other frame still
function?

Which Emacs is that.  Tip: type C-u C-x C-e after the closing
parenthesis of (emacs-version).

You need to change eshell-prompt-regexp as well. For example:

     (setq eshell-prompt-function (lambda ()
                                    (if (= (user-uid) 0) "# " "$ "))
           eshell-prompt-regexp "^[$#] ")

(You may have to restart Eshell after making this change.)

Nothing, I can`t do anything and the frames don`t even refresh, 
completly blocked.

same happens here, (emacs-version) "GNU Emacs 21.2.1
(i386-debian-linux-gnu, X toolkit, Xaw3d scroll bars) of 2002-03-22 on
raven, modified by Debian"

*complete crash*

i'd rather use Eshell though. i'll append the problems i found here:

  - when using unrecognized command options, isn't it supposed to call an
    external shell (say /bin/bash)? i'm getting:

    ~ $ ls -l
    total 35135
    usage: eshell/ls: (&rest ARGS)
    ~ $ 

  - sometimes, i open a shell in a message buffer, do some operation and
    close it by killing the process, going back to message-mode. couldn't
    find the way to do the same with Eshell.

Does 'C-x BACKSPACE' (backward-kill-sentence), work for anyone else in
eshell?  It works for me in 'M-x shell' (where shell is cygwin bash).
In eshell I get:

byte-code: Text is read-only: #<buffer *eshell*>

I'm using the default prompt with the current (last week's) build of
cvs.

This problem appears to be been fixed in 21.3.1. I had the same
experience with M-x term on 21.2.1 and after moving to 21.3.1 have not
had this problem appear.

There is eshell-kill-input (bound to C-c C-u by default) to kill all
input after the prompt.

Thanks. Last time when I changed the prompt-regexp and prompt-function 
seperately, and that's why it didn't work. I just tried it, and it 
worked fine.
