what is copy-list?

what is copy-list?

[rusi]

Im trying to use fsharp mode

It was working till yesterday

But today its barfing on (or around) the line

(setq minor-mode-map-alist (assq-delete-all 'compilation-minor-mode
(copy-list minor-mode-map-alist)))

Well it seems theres nothing like copy-list.

But how was it earlier working??

Mystified...+

copy-list is defined in cl.

Add a:

   (require 'cl)

at the beginning of the file.

Aha Thanks !

But I am really getting fed up of emacs.  Theres not a mode Ive tried
recently that "just works"
I know you may say "Why blame emacs for an fsharp problem?"

But is the (require 'cl) not emacs cruft?

Well, you could try to use an emacs written in Common Lisp (eg. Hemlock
or Climacs), but none come close to GNU emacs in number and
sophistication of add-on libraries and modes.

Of course, if you have to write the mode yourself because you're using
a new language, you could as well write it for Hemlock as for GNU
emacs.  On the other hand, the GNU emacs users count several orders of
magnitudes greater than the users of Hemlock, so it might still be
better to write it for GNU emacs.

Wow, you really don't provide a hell of a lot to go on!

Emacs version? 
fsharp version? 
Actual error message?

FWIW copy-list is a function in the cl package.

Not really.  Not requiring functions and macros before calling them is a bug
in fsharp-mode.  Whether or not 'cl should be provided as the default is
another issue all together.  The reality is that if you customize your emacs
in any significant way, you'll probably load something that requires 'cl at
runtime.  However anything that makes it into GNU Emacs must not require 'cl
at runtime.  This is the current policy, but lots of people disagree with
it.

CL (non-inclusion) is emacs cruft

It's not fsharp-mode that requires cl, it's his .emacs that's trying to 
use a cl function to perform some customization of it.

This code is from the inferior-fsharp-mode function in inf-fsharp.el
from
http://sourceforge.net/projects/fsharp-mode/

(assq-delete-all 'compilation-minor-mode (copy-list minor-mode-map-
alist))

When a (require 'cl) is added to the file the problem goes away.

The problem does not usually surface because the require is there in
other (fsharp related) el files which require cl.

If that is not a require problem with the fsharp mode, there is
something very basic I dont understand (Not claiming I know emacs/
elisp very well)

I misunderstood the original post, I thought he was trying to customize 
fsharp-mode.
