Subject: bug#9907: 24.0.90; eshell:for command destructivly modifies list variables
Date: Sun, 30 Oct 2011 01:09:06 +0200 [thread overview]
Message-ID: <87ehxv5ral.fsf@luca.i-did-not-set--mail-host-address--so-tickle-me> (raw)
M-x eshell
$ for l in $load-path {echo $l}
Do this two times. After the first time the value of `load-path' is
gone, because the lisp code implementing the loop destructively modifies
this list. Idea of the following solution: Copy it.
diff -c -L /usr/share/emacs/24.0.90/lisp/eshell/esh-cmd.el.gz -L \#\<buffer\ esh-cmd.el.gz\> /tmp/jka-com2122MHr /tmp/buffer-content-2122LbA
*** /usr/share/emacs/24.0.90/lisp/eshell/esh-cmd.el.gz
--- #<buffer esh-cmd.el.gz>
