Hi !
What's the deal with SDL v1 vs SDL v2 ? Any reason why SDL1 support
should stay ?
Sorry I had actually started making some changes to have a bit more
consistency in the code style and I feel it would be to revert that now.
I'm sending your this work in progress so you can have an idea.
You can drop the attached keymap.c in src . I attached a keymap for the
French keyboard.
Essentially the keymap is now an KeyMapping array.
You can define the SDL scancode and one modifier, and the list of
scancodes that this should produce. So we can send ALT or SHIFT-ALT for
example, in addition to the key to press.
I added an optional mask so the mods of the PC key pressed can be masked
out, so to make the rules more generic, but I'm not sure if that's
really useful.
The attached code (kind of) works well for my French keyboard (at least
I can produce all characters except § which I never use), but there are
some problems as I'm probably confusing the TOS when sending a SHIFT/ALT
scancode when that same key was already pressed. Also problem when we
have a shifted key on the PC but unshifted on the Atari (§). I'll have
to better keep track of what modifiers are already pressed so I don't
"press" them again, and don't release them.

Hi,
Thomas is probably best person to comment on this,
but until we've removed support for SDL v1, these
kind of changes should support both SDL v1 and v2.
Regardless of that, could you send your PoC changes as patch to list?
(Just the relevant changes, no extra white space
changes etc.)
Keymap file format change isn't necessarily much
of a problem, if you could provide also (shell or
python) script that can convert between the
formats.

Dear Hatari developers,
I am new to Hatari development. I am French, 43 and I also follow
EmuTOS and FreeMiNT development although I listen and learn at the
moment.
You have been doing a fantastic job with Hatari, thank you for such a
great piece of software !
As a French keyboard user, I am suffering from the inconvenience of
the "alt-shift" keys which are not well supported currently, and I
have decided to do something about it.
I have made a proof of concept where I modified keymap.c with the
following improvement:
The keymap is now an array of KeyMappings structs which have the
SDL_keysym on one hand, and a list of ST scancodes on the other hand.
By pressing AltGr-' on my French PC keyboard, Hatari sends scancodes
of shift-alt-# to its "ikbd", and an opening curly brace is correctly
output in e.g. STeno or EmuCON.
So this works and should enable to bind any key+modifiers from the PC
to any sequence of scancodes on the ST side, solving that old problem
for good.
Now I need to be able to make that configurable and enhance the
format of the keymap configuration file to support this and I would
your advice for this.
Obviously I could make something that works with scancodes numbers
only, but it would break the current "symbolic" mapping which
although not perfect, is easy to use and understand.
I've had the following ideas:
1 Use some "section" delimiter in the config file so to indicate to
the parser how to interpret following the lines.
SYMBOLIC
Y,44
Z,21
SCANCODE
21|200,2a|38|1a
(we could also allow usage of modifier names or ST modifier names to
make things more friendly, ie 21|KMOD_RALT,LSHIFT|ALTERNATE|1a)
2 Introduce some prefix to indicate to the parser what is we're
describing. Eg s for symbolic, r for raw (scancode).
sY,44
r21|KMOD_RALT,LSHIFT|ALTERNATE|r1a
But that would break backward compatibility with exiting keymaps...
None of that sounds great... By default I'd go with the scancode
because it's the most robust. There is only a handful of keys to
"override" anyway so we wouldn't compete with /etc/termcap's
complexity. We can also ship a few standard keymaps. But then what do
we do with existing user keymaps...?
Thanks for any idea!

# Keymap. This format allows you to associate SDL key descriptions with
# scancodes simulating the corresponding keys pressed on the emulated ST.
#
# Format is the following:
# <host_description>,<guest_description>
#
# <host_description> is the scancode the key pressed (which you can see
# when running hatari with the "--trace keymap" option. Optionally you can
# add a SDL key modifier. These are described in
# https://wiki.libsdl.org/SDL_Keymod#Related_Functions.
# You can also add a modifier mask. This mask will be bitwise "AND"ed to the
# actual key pressed before it is compared with items from this keymap.
# This allows you make mappings work regardless of the status of other
# modifiers (e.g. NumLock).
# All these (scancode, modifiers, mask) must appear in this order and be
# separated by a pipe |.
#
# <guest_description> is the pipe-separated ordered list of scancodes to send
# to the ST (3 max). For convenience you can use LSHIFT, RSHIFT and
# ALTERNATE in lieu of 2a,36,38 respectively.
# You can find scancodes in many Atari documentation places, e.g.
# https://tho-otto.de/keyboards/
# or https://freemint.github.io/tos.hyp/en/scancode.html
#
# Notes:
# * All scan codes must be in hexadecimal.
# * The parser is not very smart so don't add spaces etc.
