Automatic capitalisation might interferes with keyboard shortcuts.
|
|
Specify the behavior of shift for a layout. This is intended for locales
that use the same alphabet but have different capital letters (eg.
Bengali).
The modmap is defined like this:
<keyboard>
<modmap>
<shift a="a" b="A"/>
</modmap>
</keyboard>
|
|
This unconditionally removes all pointers (touches) pressing modifiers
which are not already locked, avoiding that the (currently) latched
modifier will be locked aventually.
This can be verfified while sliding the space bar to move the cursor
left or right.
Closes #319.

The previous algorithm did not cut the circle into 16 equal parts.
The division by 2pi yielded numbers smaller than 16, which no longer
made sense after the cast to int.
|
|
The Corner class is removed. The "localized" flag for all the corners is
held in a bitfield.
|
|
'Keyboard.Key' now contains an array of size 9, giving each keyvalue an
index. The algorithm for finding the nearest key during a swipe now
needs 16 segments, which are now calculated as an angle.
The algorithm does one more interation instead of 2 more, slightly
reducing the sensitivity of corner values. The 'getAtDirection' function
is moved into the Pointers class to clearly separate the two systems.
The 'edgekey' attribute is now obsolete but is kept for compatibility.
The flag is removed internally, key index are simply translated.
Similarly, the 'slider' attribute now act on keys at index 5 and 6
instead of 2 and 3.

Auto-capitalisation triggers when the backspace key is used. Make sure
to not remove a locked shift pointer.
|
|
|
|
The special handling of arrow keys have been removed in 854eff2. Key
repeat was not starting when the key0 was empty.
|
|
A sliding pointer going up must not cause a key event to be sent. This
caused an extra cursor movement and cleared the latched modifiers.
|
|
Send key events for the left or right arrow as the finger slides on the
space bar.
Can be used to select text by holding shift. Works under Termux.
Events are sent linearly as the finger travels. The distance between
each events is defined from the swiping distance divided by 4.
'slider="true"' can be set on a key that have 'edgekeys="true"'.
'key2' and 'key3' represent the right and left keys.
|
|
It allowed to modulate the repeat speed of some keys (arrow, backspace,
delete) by move the finger farther or closer to the key.
In practice, this wasn't pratical and doesn't seem popular. It is
removed in favor of a better mechanism for moving the cursor.
|
|
The cancel event ends the motion, it doesn't apply to a single pointer
like it was previously expected.
|
|
Especially annoying now that modifiers are not locked by a double tap.
|
|
|
|
The key enable caps lock immediately. It does nothing if caps lock is
already enabled.
It is not present on the keyboard by default but a place is defined on
every layout, top-right of the shift key. It can be enabled in the
settings.

|
Add a flag to recognize fake pointers and avoid clearing the
intentionally locked shift key.
|
|
Modifiers can be locked with a long press. The key repeat mechanism is re-used
and the press timeout is the same.
Every modifiers can be locked that way, not only the "lockable" ones.
The previous behavior can be enabled in the settings (for shift only)
but the default is changed.
|
|
Keep track of end-of-sentence characters while typing and automatically
enable shift when appropriate.
The last few characters just before the cursor need to be queried in
some cases: Begin of input, cursor has moved or text is deleted.
This might have a performance cost.
This normally only enable shift but it also needs to disable shift when
the cursor moves.

The Math.floorMod method was added on API level 24.
|
|
The "loc " prefix for predefining a place for an "extra key" was broken
since 31d6a70.
The FLAG_LOCALIZED flag cannot be used anymore, as adding it to any key
would turn it into a different key that wouldn't be recognized by parts
of the code comparing the keys (placing the extra keys).
Add an other layer in KeyboardData to store such informations.
|
|
This makes KeyValue objects smaller. 'equals' and 'hashCode' are now
implemented too. Key names are still used to recognise keys with special
meaning, but not for comparing keys anymore.
|
|
Negative values for internal events are preventing further refactoring.
Add a new kind of key and split internal events (now Event) and
Android's key events (now Keyevent).
Use enums events and modifiers outside of the KeyValue class.
Internally, they are converted to and from integer.
|
|
These two fields couldn't have an interesting value at the same time.
As we can no longer rely on a special value to distinguish between
what's the kind, the kind of the key is explicitly encoded in the two
most significative bits of the _flags field.
Extra nice thing: This removes the special values 'EVENT_NONE' and 'CHAR_NONE'.
|
|
The meaning of the public fields of KeyValue was quite complicated and
not handled consistently accross the app.
Make these fields private and add a more abstract API on top.
The meaning of these fields changed recently and it wasn't an easy
change. I plan on making more changes in the future.
|
|
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.

|
The previous limit was checking d-1 and d+1, the new limit also tries
d-2 and d+2.
|
|
Fix the bug introduced in the parent commit.
|
|
The "closest key" logic must be careful not to reveal keys removed by a
modifier.
Must check [_handler.onPointerSwipe] for every candidate values.
[selected_value] is changed back to [selected_direction].
This adds a new bug: When the direction change, the selected value might
not change but a vibration will be triggered anyway.
|
|
getAtDirection was too hard to maintain and might contain bugs.
Change slightly the meaning of directions and implement a the nearest
key calculation as a loop.
|
|
|
|
fix a direction
|
|
It was possible to latch and lock the same modifier several time at the
same time independently. Remove that.
|
|
When typing fast, a second key might be pressed before the first is
released.
Clearing modifiers earlier would prevent this but would break modifiers
placed in corners (especially the accent keys). Instead, don't take
latched modifiers into account when registering the second press.
A new flag is needed to not interfere with holding modifers, which is
merged with the norepeat flag.
|
|
The View no longer keeps flags for something other than rendering.
|
|
Modifiers can temporarily remove a key from the layout by returning
'null'.
Make sure pointer handling code handle these modified keys gracefully
and doesn't trigger a key event and a vibration for the removed key.
|
|
On some devices, bogus touch events can be sent while holding a key.
With modulated keys, it can happens on top of other keys.
Ignore every new pointers when a modulated key is pressed.
|
|
Handling this event is part of the API but was never done. This caused
unstoppable key-repeat.
This event isn't common, the only way I found on Android 10 is to switch
to the emoji keyboard while holding a key. Some apps might cause this
event more often.
|
|
|
|
Pointers.getKeyFlags might receive a different KeyValue than what's
stored in the pointer due to caching. Compare names instead.
|
|
Make modulated keys repeat twice as slow by default and start repeating
twice as early.
|
|
Change the formula: don't use an external constant, add a state.
It's now the ratio between where the finger is at the first repeat and
where it is now.
Keep the repeat going when swiping into an other key. Currently only for
arrows: It's now possible to go from an arrow to an other without
waiting again for the key repeat timeout.
The backspace and delete keys don't work well with this.
|
|
Separate the concerns and have a clearer interface between the two parts
of the code.
