There was no free bits left to add new modifiers. Instead of increasing
the width of the 'flags' field, refactor the way modifiers are
represented and used.
Modifers are now represented as independent values and stored in the
'code' field. A flag is added to distinguish between modifiers and keys
with a key event.
The most notable change is that modifiers can no longer be or-ed into a
single value but have to be represented as an array.
Layouts no longer need to mention every localized keys and dead keys.
They are now placed automatically starting from the second row on the
bottom-right corner.
The "loc " prefix is not removed to still be able to define a more
optimal and consistent placement for some extra keys (eg. 'ß' near 's').
Programming layouts no longer need to place every dead keys.
Allow specifying a layout for programming and add a key for switching to
it easily.
The switching key is placed on the top edge of the space bar.
The option has no effect by default because the ergonomic isn't ideal,
it needs to be enabled explicitly.
Users of Latin-script languages certainly prefer to use one layout (for
programming or not). This feature might be removed in favor of a better
language-switching mechanisms in the future.
Before sending a key event while modifiers are active, send events for
the modifier keys.
Some applications don't look at the "metaState" flags but instead keep
track of the up and down events for the modifiers.
For example, the basic text views that are in every applications
correctly handle the "metaState" flags except for one binding:
Selecting text with the arrows while pressing shift.
Show these characters only for users that have the corresponding locale
installed (a supported eu language for €, en-GB for £).
Add these characters to most layouts.
There were two problems:
- The Action key was swapped when it shouldn't be. The flag
'IME_FLAG_NO_ENTER_ACTION' wasn't interpreted correctly for inputs
that specified both an action and this flag.
- The value 'IME_ACTION_UNSPECIFIED' should remove the Action key.
It is placed on the top-right of the enter key on every layouts.
It sends a special event (performEditorAction) instead of writing a
newline.
The "actionId" is passed through the EditorInfo object in an obfuscated
way so it's not clear whether it's using the right one.
Add a "Theme" option to choose between a dark and light theme.
The light theme uses the colors of the dark theme with the luminance
inversed.
The reloading after a configuration change is changed slightly:
- Special handling is needed when the Theme is changed (recreate the views)
- The default implementation of 'onConfigurationChanged' is used
Which triggers more refresh (but don't recreate the views)
- 'onCreateInputView' is no longer needed
API level 12 is required for "subtype" code introduced in 1.7.
This adds a fallback for older version, "subtype" features are not
available but the keyboard is usable.
Changet he minimal version to 4 to be able to query the API level.
Using integer constant for versions because that's how it's presented in
the documentation. Build.VERSION_CODES is WTF.
This replaces the "disable accent keys" checkbox.
The default should work for anyone: Accents will be hidden unless the
user has the french language installed.
The value "show every accents" is useful for versions of android that
don't have subtypes.
KeyValue defines an ADT and some of its values, it now contains public
final fields and no internal logic.
KeyModifier handles modifiers and accents and creates new instances of
KeyValue when needed.
This operation is now properly cached.
Remove the use of [getIdentifier] because it requires the current
package name to be passed, which can't be found reliably since the
change in build system.
