Touch zone decouples screen size from gesture event registration.
The win here is each individual widget does not need to update
gesture range on screen rotate/resize anymore.
Another advantage is we now have a centralized ordered array to handle
all registered touch event listeners, makes it much easier to resolve
gesture range conflicts between multiple widgets.
This patch also includes the following changes:
* migrate readerpaging to use readerui's touch zone
* migrate readerfooter to use readerui's touch zone
* move inverse read direction setting to touch menu's setting tab
* moved kobolight widget from readerview into readerui
* various dead code cleanups and comments
and have more confidence with the unit testing framework.
Now `make testfront` won't retry on failure and testing files are
ordered in each run so that it's possible to reproduce testing failure.
And this patch also fix flush settings not working before suspend issue:
at some point the `FlushSettings` event is sent to `UIManager` instead
of `ReaderUI`, but `UIManager` only delegated events to active widgets
and `ReaderUI` is actually not an active widgets thus will miss the event.
This patch also add a verbose debug mode with "-v" as a switch to turn
on this mode. With verbose mode on, event handling will be logged.
Since the doShowReader will run in nextTick, it will get picked up by
checkTask, which is in the beginning of next UI loop and blocks
UIManager from redrawing the screen for the info popup.
The 'KOSync' plugin will synchronize furthest reading progress
across different koreader devices after users registering their
devices.
The synchronizing service is open-sourced as the project
[koreader/koreader-sync-server](https://github.com/koreader/koreader-sync-server).
This is a larger clean-up of the refresh situation.
The general shift is that refreshes are now mainly triggered by
the (top-level) widgets when they get shown or closed via UIManager.
All refreshes for the widgets when they are in use were handled by
themselves before. This adds the case of showing/closing.
It is the desired result of not having UIManager:show()/:close()
do (full screen) refreshes on its own.
This is a major overhaul of the hardware abstraction layer.
A few notes:
General platform distinction happens in
frontend/device.lua
which will delegate everything else to
frontend/device/<platform_name>/device.lua
which should extend
frontend/device/generic/device.lua
Screen handling is implemented in
frontend/device/screen.lua
which includes the *functionality* to support device specifics.
Actually setting up the device specific functionality, however,
is done in the device specific setup code in the relevant
device.lua file.
The same goes for input handling.
Since wikipedia server is language specific we should first detect
language of the text by querying Google Translate. Make sure you have
access to both Google Translate and Wikipedia service to use this
function.
