* Completion with M-Tab for custom type 'directory

In Info

  `directory'
       The value must be a directory name, and you can do completion with
       `M-<TAB>'.

Does this work? On w32 I can of course not do M-Tab, but I have another 
meta-key to, but that does not seem to work.

Could it be bound to something useful instead? M-k for example?

Doesn't ESC-Tab work on windows?

Yes, but I saw some strange things. First I got into that "show initial 
lisp value" state. Then I did not do that any more, but I really do not 
understand why. I start with (customiz-option 'my-opt).

Then, in the correct state, I put the point  to the beginning of the 
field. If I then type Esc Tab I get an "Wrong type argument: stringp, nil".

After moving the point a bit to the right I actually have completion 
working.  But, ...

1) If there are spaces in the directory name it stops working.

2) I can not click with the right button to select from the list. I have 
set w32-num-buttons to 2. Should not the right button then be mouse-2?

3) I can not select with RET in the selection list (because viper is 
active in the completion buffer).

The problem with the state was because I set the default value to nil 
instead of "".

Hmm, I get a huge list of symbols to complete against. Even at the
beginning of the field without deleting the initial "nil".

I don't know about windows, but on Unix-likes, the right button would
most probably be button 3.  With a 2 button mouse, you'd either have to
hit both buttons (or the scroll wheel if one exists) to get mouse-2.

This sounds probably a viper problem.  I don't think it's a good idea to
rebind standard keys in emacs just to get viper working.  Possibly
viper.el should override keys that gets in the way.

I compared with how completion works for C-x d. In this case the default 
directory is used when the string is empty. This is of course not 
meaningful the the custom widget.

I noticed another problem (bug?). The completion list contains all 
files, not only directories. This is meaningful for C-x d, but not for a 
directory widget. To summarize the problems:

1) On w32: You can not get completion when the widget input field for a 
'directory type custom is empty. This perhaps has something to do with 
the absence of a definition of a root directory in dired too?

2) Completion for a 'directory type custom widget includes all files, 
not only directories. (Is this w32 specific?)

3) Alt-Tab is useless as a default since it is not available in window 
type environments. Esc-Tab is in this case available, but is not always 
the case. (This message has been repeated many times now and I really 
long for a resulotion of this.)

Did you really mean "in window type environments" (when using a window
system) or did you mean "in an MS Windows type environment".  (I am
not trying to nitpick on terminology, I am really not sure which of
the two you mean.)  If the former, then it is difficult to avoid
conflicts with window manager bindings, due to the large variety of
window managers out there.  A good window manager will allow you to
rebind its keys.  All of my window manager commands use the super key,
so I have no conflicts.

Sincerely,

Luc.

I get an error If the field is empty too, and if the initial input is a
non-existing file or directory.

I get that on GNU/Linux too.

Looking at wid-edit.el, it seems that the :directory type widget is an
alias for the :file widget, but I'm not 100% sure I understand the
define-widget code, so I could be wrong.

I see that is has a fixme comment stating that it should use
`file-name-as-directory' instead of `file'.

It certainly isn't useless as a default.  I use it all the time on my
GNU/Linux system.

ESC-Tab not working all the time on w32 sounds like a bug to me.

I mean on a system where a window manager is used. Several times it has 
been pointed out that many of the most common window managers uses 
Alt-Tab for window managers window switching.

And yes, I use MS Windows. Still a majority does that. We can not 
pretend that the key bindings there are unimportant. They are important 
whehter we like it or not. I think that we will get a much larger user 
base if we acknowledge that. I think that this is important in the long 
run. I have struggled to get a working environment on MS Windows to see 
if I can switch without much trouble. As long as I have trouble getting 
things working on w32 I can not switch.

In what circumstances is Esc-TAB not available?

The case I think of is when viper-mode is in vi state. I am using viper 
all the time.

Then you really should read

(info "(viper) Vi State")

This is not as much an Emacs problem as it is a viper problem, and
viper has explicitly documented and addressed this problem.

Thanks, I have read it now:

`C-\'
     Viper uses <ESC> as a switch between Insert and Vi states.  Emacs
     uses <ESC> for Meta.  The Meta key is very important in Emacs
     since many functions are accessible only via that key as `M-x
     function-name'.  Therefore, we need to simulate it somehow.  In
     Viper's Vi, Insert, and Replace states, the meta key is set to be
     `C-\'.  Thus, to get `M-x', you should type `C-\ x' (if the
     keyboard has no Meta key, which is rare these days).  This works
     both in the Vi command state and in the Insert and Replace states.
     In Vi command state, you can also use `\ <ESC>' as the meta key.

     Note: Emacs binds `C-\' to a function that offers to change the
     keyboard input method in the multilingual environment.  Viper
     overrides this binding.  However, it is still possible to switch
     the input method by typing `\ C-\' in the Vi command state and
     `C-z \ C-\' in the Insert state.  Or you can use the MULE menu in
     the menubar.

On a swedish keyboard I can not use C-\ at all. In vi state I can not 
use ESC. The window manager prevents me from using Alt-Tab. So what is 
left for completion? And note that I would pretty much want completion 
to be very easy to reach!

Suppose I do not know anything about Emacs. What would you expect me to 
think in a w32 environment with a swedish (or other national) keyboard?

Why?  What keys do you have to press to get \ and why would it be
impossible to press Ctrl with them?

It is perfectly feasible to use Ctrl-\ on a German keyboard.

Isn't C-\ just C-AltGr-+ on a typical swedish w32 keyboard?  Anyways, I
think it would be rather silly to start changing around standard Emacs
keybindings just for the combination of windows, viper and swedish
keyboards.

People who know nothing about Emacs don't use viper I'd wager.
