@Ferran: What do you exactly mean by treating different keyboard layouts as
different controllers?
The last two days I have been working on a script that iterates all kbd.cfg
files in a given folder and generates one kbd.xml file. When given the
{mixxx-dir}/res/keyboard folder, it outputs this
XML:http://pastebin.com/B18fTnsC
I think that the file speaks for itself. But here are some key characteristics:
The <controller> block starts with a <keyboard-layouts> block, which is kind of
a manifest, telling which keyboard layouts this keyboard preset supports.Each
<control> element is child element of a <group> element, which has an attribute
"name", which tells the group name:
<group name="[Master]">
<!-- This control will target the ConfigKey: [Master], crossfader_up
--><control action="crossfader_up"></control></group>
Each <control> block can have multiple <keyseq> elements, which hold a key
sequence. In Mixxx, this key sequence will be loaded in as q QKeySequence.
Each <keyseq> element can have a "lang" attribute, which tells for which of the
supported layouts as described in <keyboard-layouts> this key sequence is
targeted. For example:
<control action="beatloop_4_toggle"><keyseq lang="en_US">q</keyseq>
<keyseq lang="fr_FR">a</keyseq></control>
If a key sequence is shared by multiple keyboard layouts, it can be grouped
like this:<keyseq lang="en_US, fr_CH, es_ES, de_CH">q</keyseq>
If a key sequence is shared by all the keyboard layouts supported by the
preset, the lang attribute is not set:
<keyboard-layouts><lang>en_US</lang><lang>fr_CH</lang><lang>es_ES</lang><lang>de_CH</lang><lang>fr_FR</lang></keyboard-layouts>
...
<control action="enabled">
<!-- This key sequence is shared by all keyboard layouts, because it lacks a
lang attribute --><!-- So. In this case, it will target: en_US, fr_CH, es_ES,
de_CH and fr_FR. -->
<keyseq>Shift+F12</keyseq></control>
I am curious about what your thoughts are on the generated file!
