Add the ':char' syntax for defining character keys with a different
symbol.
This new kind of keys is used to implement Ctrl combinations in the
Serbian Cyrillic layout without showing latin letters while the Ctrl
modifier is activated.
This allows to add new kinds of keys that need more data without making
KeyValue's footprint bigger for common keys.
This changes the [_symbol] field into [_payload], which holds the same
as the previous field for more common keys but can hold bigger objects
for keys of the new "Complex" kind.
This also adds a complex key: String keys with a symbol different than
the outputted string.
Unit tests are added as the Java language is not helpful in making
robust code.
This allows adding more compose sequences without modifying
en_US_UTF_8_Compose.pre.
This is done by grouping sequences files that should be merged together
into a directory. This also allows moving keysymdef.h into that
directory.
* Fix persian's half-space invisibility
* Add a 0.5 space before ظ in persian
* Change the place of چ in persian
* Change the width of backspace in persian
* Rename zwnj to halfspace in KeyValue.java and beng_provat layout
This adds the clipboard pane, which allows to save an arbitrary number of
clipboards and to paste them later. The key can be disabled in settings.
Checking the "Recently copied text" checkbox will cause the keyboard to keep a
temporary history of copied text. This history can only contain 3 elements
which expire after 5 minutes.
If this is unchecked, no history is collected.
History entries can be pinned into the persisted list of pins.
This implements clockwise/anticlockwise circle and round trip gestures
inspired by Messagease.
The circle gestures start after a small threshold to avoid making the
regular swipe too hard to aim.
The gestures do:
- circle: The center symbol with Shift applied, with a fallback on Fn
- round trip: Same as the circle gesture but applied to a side symbol
- anticlockwise circle: Nothing currently. It is intended to be made
configurable per-layout in the future.
The new Gesture class keeps track of what the pointer is doing while it moves
on a key. It replaces the 'selected_direction' integer.
* Hangul support
This works with two new kinds of keys (Hangul_initial and Hangul_medial)
that carry a precomposed hangul syllable and act as modifiers.
The hangul syllables are composed algorithmically.
* Add shift layer to Dubeolsik layout
* Make slider speed independent from swipe distance
Swipe distances other than the default resulted in a slider that were
not easy to control.
* refactor: Add class Pointers.Sliding
It holds the states and the code needed to make the slider work.
'Pointer.sliding' is set to [null] when sliding is not in progress.
The implementation is changed not to depend on [downX] and [dx] but
instead use the pointer's [x] coordinate directly.
* Move the cursor further for faster slides
In sliding mode, compute the speed of the pointer and use it to increase
at which the cursor moves.
* refactor: Separate kind for cursor movement keys
This allows to define a key that moves the cursor more than one position
at a time.
This will be used to avoid lag during fast slider movements.
* Reduce lag when sliding quickly on the spacebar
Avoid sending key events in a loop while sliding quickly in a cursor
movement key. Key of kind Cursor_move are "multiplied", meaning a single
key event represents a movement of more than one position, reducing the
number of key events sent.
This is only for cursor move keys.
Thanks to the previous commit, a modifier key can now be more complex
than just a KeyValue.Modifier. This allows a more elegant implementation
of the compose key, that could be taken as a base for other features
(eg. unicode hex entry, hangul)
The COMPOSE_PENDING modifier is removed as keys of kind Compose_pending
can act as a modifier. This has the advantage of highlighting the key
that was last pressed in the sequence.
Rules are added to Pointers: Non-special but latchable keys must clear
latches and cannot be locked with a long press. These rules were not
needed before but were intended.
Allow keys of a kind other than Modifier to be a modifier.
This requires writing a compareTo function for KeyValue. Fields are
compared in this order: Kind, value, flags, symbol.
'FLAG_LOCKED' and 'FLAG_FAKE_PTR' are only used within Pointers.
Define new flags in Pointers and remove these from KeyValue. Also allows
to define new flags.
The kind field wasn't large enough to hold the new Compose_pending kind.
The flags field is reduced in size by removing a free spot.
The FLAGS_BITS mask is defined in a safer way.
The COMPOSE_PENDING modifier indicate whether a compose sequence is in
progress. The new key of kind Compose_pending sets the current state of
the sequence.
The compose sequences are compiled into a state machine by a python
script into a compact encoding.
The state of the pending compose is determined by the index of a state.
This separates the layout definitions from the special layouts
(bottom_row, greekmath) and other unrelated files (method, settings).
This is also a more intuitive location for layouts and make the resource
directory easier to navigate.
Under the hood, layouts are copied back into
build/generated-resources/xml.
Change the API of `KeyModifier.Map_char` to allow returning a string
instead of a single 16 bits char.
This allows to return combining diacritics.
This also gets rid of `apply_map_or_dead_char`, maps can have their own
fallback.
The slider was repeatedly sending arrow keys, which change the focused
input when the end of a text box is hit.
A new key is added that implements cursor movements using the
`InputConnection` API.
The new keys are defined as `KeyValue.Editing`, which are no longer only
context menu actions.
The behavior when a selection has started is changed. The selection is
modified instead of cleared even when shift isn't pressed or the
selection would become empty.
Fallbacks to sending arrow keys for editors that do not support the API,
like Termux.
The two layout selection options are replaced by a ListGroupPreference
that allow to enter an arbitrary amount of layouts.
The "switch_second" and "switch_second_back" keys are replaced by
"switch_forward" and "switch_backward", which allow to cycle through the
selected layouts in two directions.
Layouts are changed to place these two key on the space bar.
The backward key is not shown if there's only two layouts.
These symbols have special meaning when in `res/xml` and are escaped in
standard layouts.
The backslash is not stripped when parsed from the custom layout option.
Treat these backslashed keys specifically to allow standard layouts to
be passed back to the custom layout option.
The new key switches to any installed "voice" input method.
If several input methods matches, no effort is made to choose.
Might misbehave with some input methods other than Google's on API < 28.
It is placed on the middle of the arrows on the bottom bar. It is
enabled by default and can be removed in the "Extra keys" option.
The key is not removed from the keyboard if no voice input method
exists.
'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.
A new option changes the "change_method" into the new
"change_method_prev". It switch to the previously used input method.
A long press on "change_method_prev" sends "change_method".
A new section is added in the settings and existing options are moved.
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 most requested keys are undo and redo. Unfortunatly redo doesn't
work reliably.
The other context menu actions like share, assist and autofill are added
even thought they are rarely useful or implemented.
A new option allow to choose a secondary layout, the switching key is
placed on the top edge of the space bar.
The "Programming layout" option was basically doing that but it was
possible to choose from a few layouts only. It is improved and renamed.
The 'LayoutListPreference' allows setting the string for the first entry
but otherwise share the rest of the array.
Add nice icons from materialdesignicons.
