Message-ID: <87d1pyltd4.fsf@TK-PC.i-did-not-set--mail-host-address--so-tickle-me>
--text follows this line--

With Croatian (HRV) keyboard active, instead of executing commands
beginning-of-buffer and end-of-buffer, M-< and M-> just insert
'<' and '>' characters in most (but not all) buffers.
C-h k M-< gives: '< runs the command self-insert-command' in all user
buffers open with C-x C-f.
Also, in '*GNU Emacs and '*About GNU Emacs*' buffers M-< gives '< is undefined'.
In the following buffers it works correctly:
*Help*, *Messages*, *Buffer List*, *Bug Help*

With e.g. Spanish keyboard which has exactly the same <> key
postion (next to Left Shift) everything works OK. Also with US keyboard.
No problems with CRO(HRV) keyboard in Emacs 24.5 either.

Please try the latest pretest of Emacs 25.1, we have changed the
keyboard handling there.

Also, what happens if you use the right Alt key instead of the left
Alt key to produce M-< etc.?

From
   https://debbugs.gnu.org/cgi/bugreport.cgi?bug=23251
it is not clear what “Generate-Meta” settings are used in this bug,
given that there is no Meta key on the Windows.

    • Is it with no init/site files?
    • What happens if this key is pressed with Alt⸣s?
    • What happens if this key is pressed with left Alt?
    • What happens if this key is pressed with AltGr?
    • What happens if this key is pressed with Alt and AltGr?

Myself, I won’t be able to test this for a few days, since the only
laptop-or-hardware-keyboard about me with ISO key present is not
accessible right now.

Yours,
Ilya

On Win7, as far as it is visible from MSKLC, Spanish and Croatian
keyboards define the ISO key identically:
   Base	  → <
   Shift  → >
   Ctrl	  → FS=^\

There is no special binding for any other key (including any Alt).
Both keyboards look as having the bit KLLF_ALTGR (sp?) defined (but
probably MSKLC would lie about this!). 

Ilya

P.S.

What confuses me is
  with US keyb. AltGr-< gives: 'Ç' char. , and nothing with AltGr->.

This is not how US keyboard should behave; it does not define any
AltGr bindings!  I even checked “US International”, and while it has
SOME AltGr bindings, it has none on the ISO key.

Do you know about this one (quoting Eli):

    I also added a new variable, w32-use-fallback-wm-chars-method, which,
    when non-nil, makes Emacs use the old code from before your changes.

This way, one can check whether it is due to MY edit, bug#19994.

If it is my code which is at fault, there is a way to get finer info:
recompile with -DDBG_WM_CHARS; then my code emits several diagnostic
lines per a processed keypress.

THIS I can reproduce.  This is affected by MY patch.

Will not be able to look into it in more details quick — hopefully,

      Explanation for enquiring minds:
      ================================

OK, the reason for a peculiar behaviour of these keys is that they are
SECONDARY keypresses which produce the same character.  So:
  • The “more bullet-proofish” branch in my patch cannot handle such
    keyspresses, and
  • the fallback (“to assume that every modifier keys DID contribute¹⁾
    to the generation of the character”) turned out to be too
    simple-minded (for this unexpectedly frequent situation).

      ¹⁾ On Windows, for typical layouts, Alt (NOT AltGr!) and Win
         modifiers would not affect the generated character.

This behaviour of layouts is a little bit more widespread than what I
expected.  So far I found following pairs:

	    Primary 	  	    Secondary	      Generate
  Czech:    AltGr-Q, AltGr-W	    ISO, Shift-ISO     \, |
  Croat:    AltGr-Q, AltGr-W	    US-\, US-|         \, |
  Croat:    AltGr-., AltGr-, 	    ISO, Shift-ISO     <, >
  Slovak:   AltGr-z  		    AltGr-,	       >
  Slovak:   AltGr-.  		    AltGr-ISO	       <
  C-Y:	    US-/, US-|		    ISO, Shift-ISO     \, |

(The last row is for Czech-QUERTY, but also for most US-compatible
keyboards.)  Here US-foo means “the keypress producing ‘foo’ on US
keyboard”.

Also, on Czech-QUERTY, the following characters allow AltGr access
(“A-” below) at the “US layout locations”; together with
Czech-layout-specific keypresses, this creates duplication as (AFAIK):

  Primary:	US-!    US-`    A-US-_  A-US-:  US-<     US--     A-US--
  Secondary:    A-US-+  A-US-;  US-?    US->    A-US-?   A-US-=   US-/
  Produce:      +       ;       _       :       ?        =        -

This creates a significant mess if one wants to allow using the
secondary locations with Alt modifier (for example, to generate Meta-;
by Alt-AltGr-;).  It does not look like a small workaround is possible
(which does not break OTHER usage scenarios).

Ilya

P.S.  I know a medium-sized workaround which would improve OTHER cases
      as well.  But it cannot be ready in a day or two!]

Thanks for looking into this.

Is it possible to devise a simple work-around that would depend on
some optional variable?  The work-around doesn't need to handle all
usage scenarios, just allow using a particular keyboard layout with
reasonable results (e.g., it could break usage of some other layouts).

If such  work-around is possible, I think we should consider it for
the upcoming Emacs 25.1 as a temporary stopgap.

I much prefer a simple heuristic which (hopefully) breaks orders of
magnitude less things than what it fixes.  Hopefully, this 2-LOC edit
must be such!

It affects ONLY the discussed case (“secondary” keys), and (if the
heuristic triggers) changes it by ONLY falling back to pre-my-patch
behaviour.  I put a lot of comments explaining what happens, and
REALLY hope that the cases where this patch HURTS would NEVER arise…

Hope this helps,
Ilya

Forgot to say: I checked only the Slovak and Czech-QUERTY layouts (the
only layouts I know where the bug was triggered without ISO keys).

Every misbehaviour I noticed with the old version is fixed by this
patch.  (This includes both cases: Alt-key and Alt-AltGr-key “losing”
Alt-modifier.)

That's even better, of course.

Thanks.

I confirm that all keys work fine now.
I've tested it with more than 20 keyboard layouts (both East and West European),
and all work OK.

Thanks for testing, I'm therefore closing the bug.

Thank you for being thorough!  It is most appreciated.

Thanks, pushed to the emacs-25 branch.

Just in case somebody may try to use this table:

I got this table (what is primary/secondary) by inspecting the
output of MSKLC.  Turned out one cannot trust this output: MSKLC
reports not the current table in the layout, but what it thinks is a
“reasonable representation” (reordering keys, which is WRONG!).

Doing experiments with the buggy Emacs (and with a fixed one ;-) I see
that the actual table is much more reasonable (with one apparent bug
 — see `=´ — uncovered ;-):

  Primary:      US-!    US-`    US-?	US->	US-<     A-US-=	  US-/
  Secondary:    A-US-+  A-US-;  A-US-_  A-US-:	A-US-?   US--	  A-US--
  Produce:      +       ;       _       :       ?        =        -

Yours,
Ilya

This is just because in these buffers '<' and '>' do the same as M-<
and M->.
