[PATCH] Adding some azerty keymapping for the hotkeys

[lsdh]

On Linux (tested on Ubuntu 13.4 with gnome shell); the hotkeys ctrl+1 to ctrl+0 did not work natively in my case (but does in Windows 7, same computer). I have a Belgian keyboard, so default keymapping is really different from the US one.

A ~/.config/0ad/config/local.cfg can receive modifications to have custom hotkeys, but some keys I needed where not available: § à ç è é

Theses keys are also present in the French keyboards (the only change for theses places is at place 6: "-" instead of "§").

To have a full ctrl+1 to ctrl+0 bar, I added theses entries in the /0ad/source/ps/Keyname.cpp list :

	{ SDLK_WORLD_7, "World7", "W7" },	// §
	{ SDLK_WORLD_64, "World64", "W64" },	// à
	{ SDLK_WORLD_71, "World71", "W71" },	// ç
	{ SDLK_WORLD_72, "World72", "W72" },	// è
	{ SDLK_WORLD_73, "World73", "W73" },	// é

And configured the ~/.config/0ad/config/local.cfg like this:

hotkey.selection.group.select.0 = W64
hotkey.selection.group.save.0 = "Ctrl+W64"
hotkey.selection.group.add.0 = "Shift+W64"
hotkey.selection.group.select.1 = Ampersand
hotkey.selection.group.save.1 = "Ctrl+Ampersand"
hotkey.selection.group.add.1 = "Shift+Ampersand"
hotkey.selection.group.select.2 = W73
hotkey.selection.group.save.2 = "Ctrl+W73"
hotkey.selection.group.add.2 = "Shift+W73"
hotkey.selection.group.select.3 = DoubleQuote
hotkey.selection.group.save.3 = "Ctrl+DoubleQuote"
hotkey.selection.group.add.3 = "Shift+DoubleQuote"
hotkey.selection.group.select.4 = SingleQuote
hotkey.selection.group.save.4 = "Ctrl+SingleQuote"
hotkey.selection.group.add.4 = "Shift+SingleQuote"
hotkey.selection.group.select.5 = LeftParen
hotkey.selection.group.save.5 = "Ctrl+LeftParen"
hotkey.selection.group.add.5 = "Shift+LeftParen"
hotkey.selection.group.select.6 = W7
hotkey.selection.group.save.6 = "Ctrl+W7"
hotkey.selection.group.add.6 = "Shift+W7"
hotkey.selection.group.select.7 = W72
hotkey.selection.group.save.7 = "Ctrl+W72"
hotkey.selection.group.add.7 = "Shift+W72"
hotkey.selection.group.select.8 = Exclaim
hotkey.selection.group.save.8 = "Ctrl+Exclaim"
hotkey.selection.group.add.8 = "Shift+Exclaim"
hotkey.selection.group.select.9 = W71
hotkey.selection.group.save.9 = "Ctrl+W71"
hotkey.selection.group.add.9 = "Shift+W71"

The /0ad/binaries/data/config/keys.txt could also be updated.

I could manage to do this changes thanks to Philip` and RedFox| on the IRC, so a big thanks to them.

(to add other keys, you can temporary add the line

printf("%d %d\n", ev->ev.type, (int)ev->ev.key.keysym.sym);

in the HotkeyInputHandler function of /0ad/source/ps/Hotkey.cpp then compile and lauch the game in a terminal. an integer will be displayed when the key is pressed:

2 224
3 224

The second number (224 here) correspond to the key and this ​http://www-personal.umich.edu/~bazald/l/api/_s_d_l__keysym_8h.html will give you the SDLK name corresponding).

Some comments:

• It's better to have all changes in one diff, that can be applied a lot easier. You should use "svn diff" on the root svn directory
• Don't add debug code (like that printf line) to the changes. You're welcome to mention it in the description, but it shouldn't be added just like that
• Is it possible to use better names than W7, W72 etc? It's not because SDL uses those names that they should be in the config file.
• Those changes shouldn't be in the config file (we won't include it, as Belgian keyboards are a clear minority compared to QWERTY), but they should be added to the txt documentation file if people want to use it, or as reference for when 0AD gets multiple keyboard layout support.

But thanks for the time, it's certainly worth supporting extra keys.

I'll update tomorrow.

In fact, the only two files that should be in the snv diff are the KeyName.cpp​ and the keys.txt. the .cfg file is there if people wants to easily have it to works and the Hotkey.cpp can be deleted from the list (it only contain the commented line, so it does not helps).

With theses changes, the keys would be right for Belgian and French azerty keyboards (with little double usage of - as this key is already used for zoom-).

I see that most qwerty keyboards have the numbers at this place, so not causing problem I guess, but some special keyboards still exist, like the Lithuanian one.

Does it worth I add their specials keys?

Thanks for your interest :-)
