Using `require` didn't make much sense since most of them are only used in a single place anyway, and it takes care of a few weird interactions in the process (besides not polluting `package.loaded` with useless crap ;)).
This will make the stroke-based Chinese character keyboard compatible with Japanese kanji stroke order, with an increase of the data file by about 80kb.
This could be a temporary solution for Japanese users to type kanji before better methods are implemented.
The stroke order data are extracted from this repo: https://github.com/KanjiVG/kanjivg.
This PR makes zh_keyboard's number pad symbol mode instead of shift mode, so that numbers are shown when the keyboard is called expecting numeral input.
* Iterate over varargs directly via select if possible
* Use table.pack otherwise (https://github.com/koreader/koreader-base/pull/1535).
* This allows us to simplify a few Logger calls, as logger now handles nil values.
This PR adds support for a Thai keyboard. Layout mostly copied from my phone, with difference in diacritics placements: phone has only one key for all of them, while here we have a couple more. Swipe in different directions needed for inputing them.
Basically:
* Use `extend` for class definitions
* Use `new` for object instantiations
That includes some minor code cleanups along the way:
* Updated `Widget`'s docs to make the semantics clearer.
* Removed `should_restrict_JIT` (it's been dead code since https://github.com/koreader/android-luajit-launcher/pull/283)
* Minor refactoring of LuaSettings/LuaData/LuaDefaults/DocSettings to behave (mostly, they are instantiated via `open` instead of `new`) like everything else and handle inheritance properly (i.e., DocSettings is now a proper LuaSettings subclass).
* Default to `WidgetContainer` instead of `InputContainer` for stuff that doesn't actually setup key/gesture events.
* Ditto for explicit `*Listener` only classes, make sure they're based on `EventListener` instead of something uselessly fancier.
* Unless absolutely necessary, do not store references in class objects, ever; only values. Instead, always store references in instances, to avoid both sneaky inheritance issues, and sneaky GC pinning of stale references.
* ReaderUI: Fix one such issue with its `active_widgets` array, with critical implications, as it essentially pinned *all* of ReaderUI's modules, including their reference to the `Document` instance (i.e., that was a big-ass leak).
* Terminal: Make sure the shell is killed on plugin teardown.
* InputText: Fix Home/End/Del physical keys to behave sensibly.
* InputContainer/WidgetContainer: If necessary, compute self.dimen at paintTo time (previously, only InputContainers did, which might have had something to do with random widgets unconcerned about input using it as a baseclass instead of WidgetContainer...).
* OverlapGroup: Compute self.dimen at *init* time, because for some reason it needs to do that, but do it directly in OverlapGroup instead of going through a weird WidgetContainer method that it was the sole user of.
* ReaderCropping: Under no circumstances should a Document instance member (here, self.bbox) risk being `nil`ed!
* Kobo: Minor code cleanups.
This layout is far more commonly used on mobile devices, and allows for
much easier typing. The keyboard primarily functions through gestures in
the four cardinal directions to select which vowel kana to select. In
addition, users can cycle through each kana row by tapping the key
within a 2-second window (this is the equivalent to T9 input for
Japanese phone keyboards).
This also resolves the long-standing issue that the old keyboard did not
correctly handle dakuten (there was a standalone dakuten key which added
a stray dakuten mark, and the umlat mode which added dakuten to all of
the keys it could) and could not input handakuten characters at all.
In order to allow adding dakuten and cycling through the various
modifiers for the previous kana, we need to wrap the input-box (similar
to korean) but luckily we don't need any state machine magic since we
just need to modify the last character in the character buffer. However
because the tap timeout for T9-like-cycling needs to be reset after any
non-tap key we need to add some basic wrappers around a few other
input-box methods.
