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.
* Add section mark as an extra key in QWERTY-like layouts that don't have it already
* Add dagger (also double dagger) as an extra key in QWERTY-like layouts
This new class will help write more logs. The LogPrinter is no longer
created everytime the keyboard is opened.
An error log is added if failing to load the custom extra keys.
This is a new section in the extra keys option that allows to enter
arbitrary strings which are then added to the keyboard.
A new string is needed for the title of the section, Android's icons and
strings are used as much as possible to avoid adding more strings.
Keys are stored in the preferences as a JSON array of strings.
The current approach is hard to maintain, for example the last key
"autofill" was not displayed.
This implements a PreferenceGroup that contains the check boxes for
every extra keys without involving listing the preferences in
settings.xml.
A custom layout is used to remove the 'title' text view.
The list of extra keys is moved into the new class.
'ExtraKeyCheckBoxPreference' becomes a nested class.
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.
This function is no longer an hardcoded list of layout ids. It's
replaced by a linear scan of the previously generated array and a new
corresponding array of resource ids.
Added Romanian characters to the keyboard layout and changed the positioning
corner for the secondary characters that were conflicting with the
newly-introduced romanian characters
Added Romanian translations
Allows to define a locale's script in 'method.xml' and use that to add
the extra keys for a locale to layouts of the same script only.
A locale of an undefined script will add its extra keys to every
layouts. A layout of an undefined script will have the extra keys of all
the enabled locales.
On API level < 12 or on some rare cases, `refreshSubtypeLayout` was not
called, making `_localeTextLayout` uninitialized.
This might also happen if `getExtraValueOf` returns an invalid layout name.
eg. `method.xml` contains an invalid layout name.
`KeyCharacterMap.getDeadChar` seems to not give the expected result on
Android 4.0. This might affect many more dead key combinations that are
not fixed by this commit.
The script `check_layout.py` checks some properties about layouts.
No check is an error.
The result of running this script on every layouts is stored in the file
`check_layout.output`, which is useful to track changes.
Add make rules to run this script as well as `sync_translations`.
The `KeyEventHandler` class is intended to handle every keys and to call
into the main class through a limited API.
However, this is not true for `Event` keys, which in practice had each a
corresponding API call.
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.
The newer haptic feedback API that is used instead of the vibrator
service since ef03dfe doesn't work for everyone.
The new vibration option allow to choose both the newer API ("system")
and the older API ("strong", "medium", "light").
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.
This activity points to the system settings page for enabling input
methods. This is purely a shortcut but is expected by many users.
It could be made more useful in the future or hidden whenever the
keyboard is enabled.
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.
'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.
The 'keysHeight' field needs to be updated. As this class is not
intended to be mutable, copy the list of rows and call the constructor.
Also remove an unecessary component of the keyboard height calculation.
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.
Refactor, follow up of 90b7944. Add a modification step to the "special"
layouts: numpad, greekmath, pin entry.
Remove the apply_key0 function, which is not expressive enough.
Add an enum instead of yet an other "switch_" function.
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.
Stay on the secondary layout after a config refresh or onStartInputView.
The information is kept until the keyboard is restarted.
Additionally, move tweaking the secondary layout to the Config class now
that physical equality is not needed.
Values like 'characterSize' and 'horizontalMargin' can't be fed back into the default value because they are not of the same unit.
To avoid this happening again, change the way the default value is defined for every options.
The 'key_height' dimension was no longer used.
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.
* Add option for keyboard opacity (transparency). Keyboard background, keys and pressed keys can be adjusted separately.
* Make the borders transparent as well
* Moved setAlphas outside drawKeyFrame to top of onDraw method
setInputView() was not called when the view was re-created through
refresh_config(). Also, the refresh_config() function was not able to
properly set the current layout.
Now keep the default layout (_localeTextLayout) and the current non-text
layout (if any, _currentSpecialLayout) separately to be able to refresh
them later.
setInputView() is called everytime the view is created instead of by
onStartInputView() specifically.
The setting activity now save the preferences to the protected storage
in onStop() instead of listening for onSharedPreferenceChanged.
The callback might not be called if the "default" shared preferences is
different from the shared preferences actually used. This is unexpected
but seems to happen half of the time on Android 12.
Since f1ce6ab, this callback is critical to update the keyboard.
Restarting the application can no longer solve these issues.
Add an option for specifying an XML layout description as a string.
The option is a bit rough at the moment:
- No documentation, users have to be aware of the keyboard's code to use
this option.
- No error are shown, the layout will fallback to qwerty on error.
This function has been introduced in API 19 and deprecated in API 28.
There was no version check for API 19 but instead of adding these,
simply remove the feature for API under 28.
Themes can define the color of each borders independently. Every borders
must have the same width for now. It's possible to set a different width
when the key is activated, thought this is only used to remove borders.
The 4 themes are updated to take advantage of borders.
Remove the code dealing with InputMethodConnection from 'Keyboard2' and
move it into 'KeyEventHandler', where more editing actions can now be
implemented.
Autocapitalisation is also moved, the IReceiver interface is simplified.
The dpi values "xdpi" and "ydpi" can have wildly different values on
different devices.
The new computation defines a baseline and only take into account the
dpi values as a ratio.
On a 480dpi screen (in both directions), this decrease the value by
about 18%. This new distance felt better during testing.
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.
Store preferences in device protected storage, which is available before
the device is unlocked.
The keyboard was crashing when trying to access the encrypted
preferences.
The emoji pane uses a separate preferences file, the old data is lost.
The SettingsActivity can't easily use the new preferences storage.
Instead, it continues to use the "default" preferences store, which is
copied back to the protected storage when needed.
The 'accent_slash' was missing in the extra keys setting.
Allow to type more latin letters "with oblique stroke" or "with stroke"
that visually have an oblique bar, that were not added to 'accent_bar'.
There seems to be no "DayNight" theme compatible with older version of
android outside of the androidx library.
Using 'Theme.DeviceDefault' which is a dark theme, even if it doesn't
sounds like. Detect if a light theme should be used at activity
creation.
Similar to 'qwertz' but is wider to show äöü on dedicated keys. Some
punctuations are rebalanced to use the space better.
The default layout for de_DE is changed.
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.
This mode is annoying to some users and is disabled in most text views.
The keyboard has a fixed sized relative to the height of the screen in
landscape mode. The keyboard can't take more space than expected,
currently.
This might cause problems in the future and might be hidden behind an
option if one is found. Every text views so far seemed to behave fine.
In Turkish, upper case of 'iı' is 'İI' but Java's toUpperCase will
return 'II'.
To make 'İ' accessible, make it the shift of 'ı'. This has the
inconvenient of swapping i and ı on the keyboard.
* Added Czech translation and layout
Translated keyboard and created Czech multilingual "practical" layout for faster typing and typing in commonly used languages (German, Slovak + French w/accents)
* Update (Rephrase) full_description.txt
... to better suit the language and naturally promote keyboard's features and possibilities to a wider audience.
The Fn+switch_numeric shortcut might be hard to discover or too slow for
heavy users.
A location is allocated for the key so it has a consistent placement.
Allows to add more keys to the keyboard from a predefined list.
The implementation doesn't use MultiSelectListPreference because it
doesn't seem possible to change the item layout to properly show the
rendered symbols.
Change the capitalisation algorithm to use Android's
'getCursorCapsMode'. This requires a bit of cursor calculations but
should feel more standard.
The auto completion only triggers after a space is typed or backspace is
pressed.
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.
Bring back the "Vibration" option.
The duration option isn't added back because the vibration settings are
still handled by Android. In fact, the option has no effect if the
vibration are disabled in the system settings.
This partially reverts commit ef03dfed5c.
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.
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.
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.
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.
Since SDK 21, applications can set the background color of the
navigation bar. This is normally simply an item in a theme but it is
more complicated for keyboards.
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 required version of fontforge (from 2020!) is not available in many
distros. This is an annoying for contributors and greatly complicated
the CI and F-Droid scripts.
The generated font file is now included in the sources. Fontforge is
still needed when adding new glyphs but this is not a common operation.
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
The previous computation was very different depending on the device's
screen and accessibility options.
Given that the keyboard is supposed to fill all the space in one
dimension, the dpi unit makes little sense.
The formula doesn't mean anything in particular, it takes into account
both dimensions (x and y) and should be close to the dpi in the
diagonals (which is the direction of swipe).
This changes the actual value, on a 1920x1080 480dpi screen, the value
is increased by 20%.
The accents are taken from the Roboto Regular font (Apache 2.0), added
the dotted circle and exported with FontForge.
The argument to FontForge's Import function are changed, the fifth
argument controls the accuracy and needed to be lowered otherwise the
grave accent wouldn't be rendered at all.
When changing any numeric setting and cancelling this change, the change would not
be persisted, but the summary in the setting screen would show the last position
of the slider instead of the correct unchanged value.
This commit fixes this on the most simple way by resetting the slider position to
the persisted value.
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.
Keep the glyphs in SVG format and build the font using a FontForge
script.
A part of the previous font is kept because the sources is lost.
This adds a new dependency to the build system, fontforge.
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.
* Providing a comprehensible Brazilian Portuguese keyboard layout
removed cedille as it is already provided by an independent key;
changed layout to correspond to the locale
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.
* Clicking twice on CTRL or ALT will lock them in 'ON' state
* Make Locking behaviour optional, configurable in preferences
* Nest the new settings into a different page
To avoid spamming the settings page and repetition in the summaries.
Cannot be a popup unfortunately because that would require API >= 11.
* Add Fn and Meta

The symbols are now smaller for Shift, Space, Backspace, Delete and
some keys on the bottom row.
The previous rule was to make the text smaller for symbols made of
several characters.
This is changed to a flag approach.
Use the height of the row currently being rendered instead of the base
row size.
Concretely, the bottom row is slightly smaller and will get slightly
smaller text.
Also:
- Rewrite the label rendering code
- Render labels at the middle of the key (was slightly off)
Instead of a fixed size that don't work at all for bigger screens.
Other tweaks:
- Use the value-land dimens to vary 'extra_horizontal_margin'
- Move label size to Config, because it can change at runtime (rotation)
- Slightly decrease the size of "long" symbols
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.
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.
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.
