Duh!  Thanks for catching this.  Please M-x report-emacs-bug!

Inner workings of `pcomplete'

Dear all,

I'm working on a small package aiming at providing basic completion for
GHCi commands in `inferior-haskell-mode':

https://github.com/manzyuk/ghci-completion

The package uses a combination of the standard completion UI (for GHCi
commands) with `pcomplete' (for arguments to particular commands).

I've been experimenting recently with identifier completion and I've
stumbled upon the following issue.  I'm not sure whether it is a bug in
the code or in my understanding of it.  Everything below refers to the
latest Emacs 24 (24.0.93.1).

To enable `pcomplete' in `inferior-haskell-mode', I add the function
`pcomplete-completions-at-point' to `comint-dynamic-complete-functions'.
Experimenting with identifier completion, I started to receive the
errors "Wrong type argument: stringp, nil", which I traced back to the
call

(pcomplete--common-quoted-suffix pcomplete-stub buftext)

in the body of `pcomplete-completions-at-point'.  Now, `pcomplete-stub'
is bound to nil at the beginning of the function using let* and it is
expected that the function `pcomplete-completions', which is called
later, will change the value of `pcomplete-stub' by side-effects.
Apparently, this doesn't happen and `pcomplete--common-quoted-suffix'
receives nil as its first argument, which triggers the error.

display-buffer-reuse-frames in a tiling WM

Hi all,

I have a question about the behaviour of display-buffer-reuse-frames
when using a tiling window manager (Xmonad in my case). The
documentation says:

"In addition, if the value of display-buffer-reuse-frames is non-nil, and
the buffer you want to switch to is already displayed in some frame,
Emacs will just raise that frame."

As I understand it, this just calls XRaiseWindow on the frame in
question. On XMonad (and presumably other tiling WMs) this has no
apparent effect when the frame is on a different workspace. This throws
me into confusion for a few seconds wondering why the buffer hasn't
opened. Is there any way to improve this behaviour? Even being able to
optionally set an URGENT hint on the window would be very useful I
think.

Thanks
Alex

Re: multiple async-shell-command?

I use openwith (http://www.emacswiki.org/emacs/OpenWith), which works with dired.  Maybe it's not
quite what you're looking for, but it can certainly open more than one file with an external application. 
The version in the wiki causes the external programs to close when Emacs closes, because they're
subprocesses of Emacs.  I've modified it to disown the processes so they stay up even after Emacs closes.  I
just submitted a patch; you can get my version here: http://pastebin.com/F5kxd6sm.

Re: Remote editing using emacsclient.

I wanted to do this as well, and I could never get it working.  As far as I could tell, it connected to the
emacsserver without issue, but then wanted to create the emacsclient on the server machine.  IIRC, if I
played with the DISPLAY variable, it would create an emacsclient window on the server machine, which
seemed profoundly useless.  So the best thing is probably to run emacsclient through ssh -- that's what I do
anyway.  There was a discussion on reddit.com/r/emacs about this several months ago, but I can't find it.

Make find file case insensitive

Is there a way to make tab completion in find file (C-x C-f) case
insensitive?  I'm on Mac OS X with hsf+, so the filesystem is case
insensitive.  I didn't find any options in M-x customize for this.

How do I make emacs indent treat #ifdef and #endif as if they were { and }?

Hi,

I've tried to figure out how to make emacs indent #ifdef blocks just like it would curly brace blocks. With a
twist though… I'd prefer if I could convince emacs to indent include statement half the amount of
whitespace that normal code would be indented. 

My preference is to indent code with 8 spaces (or one tab of that size) and then use 4 spaces for include
statements. Within code my preference would be if "#ifdef" was treated exactly as a "{" and "#endif" like a
"}", indentation wise.

Like this:

#include <ifaddrs.h>
#ifdef __linux__
    #include <sys/socket.h>
#endif

int 
func(void)
{
        int foo = 0;

        #ifdef DO_STUFF
                foo = do_stuff();
        #endif

        return foo;
}

instead of the current affair:

#include <ifaddrs.h>
#ifdef __linux__
#include <sys/socket.h>
#endif

int 
func(void)
{
        int foo = 0;

#ifdef DO_STUFF
        foo = do_stuff();
#endif

        return foo;
}

Messing around with the indentation functions in emacs seems like a black art. Likely because I don't do
lisp well... 

Would anyone have code that solves this or pointers to something that is close to what I want?

Thanks a lot,

How can I run multiple simultaneous async-shell-command?
Or is there another/better way to do what I want?

Border around selected window

Hello.

Is it possible to have a border around the selected window?

Is it possible to have a single border around the selected
window, its header-line and its mode-line?

If so, how to enable them?
