Re: Autogen in Emacs Shell

[Alexander Shukaev]

​My goodness, this is so weird.  I start to hate that, sigh...  T_T

So to check that it's indeed "/etc/profile" involved in changing to "~".  I
do the following:

1.  Start 'bash' with "M-x bash RET":

  (defun bash
      (&optional buffer)
    (interactive)
    (let ((explicit-shell-file-name "bash")
          (explicit-bash-args '("--noediting" "-i")))
      (setq buffer (my-call shell buffer)))
    (with-current-buffer buffer
      (when (equal (buffer-name) "*shell*")
        (rename-buffer "*bash*" t))))

​NOTE: `my-call' macro just properly handles whether to
`call-interactively' or not.​

2.  I have "~/emacs.d/init_bash.sh" with

  . /etc/profile

As a result, here is what I see when I start `bash' from some buffer which
contains file with path let's say "~/dir/file":

2015.05.01 Friday 16:07:21
Haroogan@G75VW:~/dir
$ ]0;~
Haroogan@G75VW  ~
$

A few points here.

1.  The first prompt is of course mine (coming from ".bashrc").
2.  Then there goes garbage, it's a separate story by the way.  I think I
discovered a bug: this garbage appears when there is some content
in "~/emacs.d/init_bash.sh".  Does not matter what kind of content that is,
e.g. it could be even be comments.  The main point is that the number of
those garbage lines that will appear on the start of `bash' is equal to the
number of lines written in "~/emacs.d/init_bash.sh".  Like in this case, we
just have one line in "~/emacs.d/init_bash.sh", so the garbage appears one
time.  I mean it's like it really types those newlines into shell.
3.  Finally there is another prompt which is obviously coming from the
sourced "/etc/profile".

I've scanned "/etc/profile" and other files that it sources.  There is no
evidence of `cd' to "~".  I'm attaching it here, can you find anything that
would change to "~"?  Thank you.

​Regards,
Alexander​
