The euro symbol in emacs

The euro symbol in emacs

[Guido Van Hoecke]

Hi,

Adapted from many posts and pages on the net, I have following piece of
lisp in my .emacs to be able to insert the euro symbol:

  (global-set-key (kbd "s-2") (lambda () (interactive)  (insert  ?€ )))

That works fine for text buffers, but it does not work in the prompt area.
It does not work e.g. when one wants to search for a € in a text buffer.

So is there really no way to specify the character code corresponding to a
key combination in such a way that it also works at the emacs prompt?

Hi,

Maybe this is what you’re looking for: C-x 8 RET (insert-char), followed
by the code point or name of the character, i.e.,

C-x 8 RET 20AC
C-x 8 RET EURO SIGN

I see now that it’s not, you want to keep your binding!

Why do you even need that?  Why not use an input method?

Try

   (define-key input-decode-map [?\s-2] [?€])

The prompt area is read-only, normally.  My crystal ball tells me that
you really mean "in the minibuffer", i.e., during input.

For that, try adding that binding to one or all of the minibuffer
keymaps.  It is probably enough to add it to only `minibuffer-local-map':

(define-key minibuffer-local-map (kbd "s-2")
                                 (lambda () (interactive) (insert ?€)))

This sounds like the way to go, but it doen't seem to work. Tried the
minibuffer-local-map as well as all other minibuffer-*-map maps that are
listed when completing F1 v minibuffer-

Well, I'll stick with C-X 8 RET 20AC for now...

You also mentioned searching, so have a look at 'isearch-mode-map'.

    isearch-forward is an interactive compiled Lisp function in `isearch.el'.
  --<snip-snip>--
    As you type characters, they add to the search string and are found.
    The following non-printing keys are bound in `isearch-mode-map'.

IMHO you're going about this the wrong way. What you should probably be
using is an input method (see the Emacs manual for details). If you set
(or customize) the variable `default-input-method' to something like
"latin-9-prefix", you can use C-\ to toggle the input method and then
type the Euro symbol with the sequence «~e» (without the guillemets, of
course). This also works in the minibuffer, to the extent it makes sense
(e.g., in isearch-(for|back)ward, etc. The isearch prompt ever tells you
that an input method is active.) The latin-9-prefix input method also
allows you to type other characters, such as ë, é, è, ï, ç, etc.

Another method is to configure your keyboard layout in such a way that
you can type the Euro symbol by using some modifier key. AFAIK in
Windows and OS X this is already configured, though you'll need to find
out which key combo to use. On Window, I think it's AltGr+2 or AltGr+e,
on OS X ⌥⇧2 (option-shift-2). On Linux, you may need to configure it
yourself, or it may already be set up, depending on your distro / window
manager.

If you really want to use Super-2, it's probably better to (on Linux)
use Xmodmap or your WM's keyboard settings. That way, the method works
in every app that supports the Euro symbol, not just in Emacs, and it'll
work in the minibuffer as well without having to hunt down the correct
keymap variables.

Joost,

You solved my problem.

I used the free Ukelele app [1] to remap my rarely used ± key to emit € and
my problem is solved.

And as you pointed out, this solution works everywhere.

Thank you, and all other people that have been helping in this thread.

Works for me.  (I don't use a `super-' modifier, but putting,
say, "C-o" in place of "s-2" shows that it works fine.)

Does not work​

​for me. Tried minibuffer-local-map as well as
minibuffer-local-isearch-map. Tried C-o, C-i, C-2 as well as C-`, but no
success.

Of course, the fact that I am an evil user probably complicates things :(

Anyway, the remapped PLUS MINUS key works well for me.

Have a nice weekend,

Guido​
