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.
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.
The icon is from materialdesignicons.com.
The "f11_placeholder" and "f12_placeholder" keys were equals since
31d6a70.
Add an incrementing id into the unused key value to differentiate
placeholder values.
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'.
Two advantages:
- No need to distinguish modifiers in KeyEventHandler. The KeyValue is
enough to decide what action to do.
- Keys are never a Char and Event at the same time, fields can be
merged.
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.
Each layouts can chose which key are localized instead of specifying it
globally for each key.
Important keys are no longer removed from layouts if the 'extra_keys'
mechanism is not working properly. This can happen if language tags
specified in method.xml don't match the user's language.
Removed some currency symbols from some layouts. They are all in the Fn
layer.
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.
Requires two new diacritics: ogonek and dot_above.
The new accents are also added to the Latvian layout as the two language
can be close but not to the other localized layouts. A new mechanism is
needed to reproducibly add extra keys to layouts without manual
placement.
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.
Revert to previous version, the original google material icon,
which is not rounded, and it looks better with the rest of the keyboard,
also more correct to represent the open box unicode space char,
instead of a smile
