Subject: 23.2; shell problem with $( and !!
Date: Sat, 12 Feb 2011 20:32:16 -0500

In a shell window using "!!<tab>" when the previous command uses "$(
... )" improperaly adds a space between the "$" and the "(".

Starting with a directory containg a file named "test", here's how to demonstrate the problem:

1) In a shell window I can execute "find . -name test" and it'll find the 1
file that's truly in the current directory.

2) I can then execute 'ls -l !!<tab>' and the expansion will be "ls -l
`find . -name  test`" which is correct.

3) I can also execute 'ls -l $( find . -name test)` and the test file will
be correctly listed.

4) However, if I then type 'ls -l !!<tab>' the "$(" becomes "$ (" (with
a space in the middle), and the command fails.

Hi Glen,

Sorry about that, and I thank you for writing.  I had wondered why
there wasn't an autoresponse to the bug report. 

Evidently emacs' bug reporting system picked up my machine name
from /etc/hosts, which I didn't realize, rather than my email address.
How do I tell emacs my email address so that bug reports will be
correct (without needing manual fixing)?

FWIW, the fix for 1795 is defective.  It fixes the changing of "$(" to
"$ (" when "!!<tab>" is used.  However, when "!$<tab>" is used to get
the last argument, the 1795 fix duplicates the whole previous line.

It's my belief that "!$<tab>" and "!$<enter>" should behave the same,
but they don't and it's frustrating.

 David

I think you can set user-mail-address.

Perhaps report-emacs-bug should be improved in this regard.

Try setting shell-delimiter-argument-list to nil.
(Though I don't know if this will have any other adverse affects.)

Version: 24.1

As a test, I have set shell-delimiter-argument-list to nil in the Emacs
trunk. It fixes this issue, but may cause other issues.

If it does, maybe add something like shell-delimiter-no-break-re (cf
f90.el) that specifies a list of tokens containing delimiter characters
that are NOT to be broken.

[ resent from 
http://lists.gnu.org/archive/html/emacs-devel/2011-06/msg00392.html ]

Hi.

Today I tried to cd into a directory named "Introduction & motivation/"
while in shell-mode, by typing I and then TAB.  To my surprise the
resulting expanded and quoted name was "Introduction\\ &\\ motivation"
instead of "Inroduction\\ \\&\\ motivation".

Unfortunately I only realized what was going on after hitting RET and
having bash trying to execute the command "motivation".

Seems that the default value of shell-delimiter-argument-list was
changed to nil as a way to fix bug #8027 [1].  As a consequence the
expanded filenames in shell-mode are not safe to be included in a
command line.

Is that a definitive fix or just a workaround until a better solution is
found for the problem with the !! completion?

I have reopened this in light of the message I forwarded from
emacs-devel. Probably this change should be reverted and re-done another
way.

I reverted it.

This bug has been re-opened due to duplicates, but I'd just like to also
point out that I just tried this Emacs 25, and can reproduce the
original problem.
