Get rid of the doc & seqtext fields, as they are not actually used (nor
are they particularly useful, the event handler's name should be pretty
self-explanatory).
Also, tweak the key_events documentation to highlight the quirks of the
API, especially as far as array nesting is involved...
Random drive-by cleanup of the declarations of key_events & ges_events
to re-use the existing instance object (now that we know they're sane
;p) for tables with a single member (less GC pressure).
* Added a new plugin external-keyboard. It listens to USB events. When keyboard is plugged in or plugged out, it updates device and input configuration accordingly.
* Added new fake events UsbDevicePlugIn and UsbDevicePlugOut that are emitted when a device is connected to a book reader that plays the role of USB host. The usage of the existing events UsbPlugIn and UsbPlugOut has not changed - they are used when a reader is connected to a host. The koreader-base has a related PR for those events.
* Did a small refactoring of initialization for the modules FocusManager and InputText. They check device keyboard capabilities on their when the module is first loaded and store it. Some of the initialization code has been extracted into functions, so that we can re-initialize them when keyboard is (dis)connected.
* Initial implementation centered around text input, and tested with USB keyboards on devices with OTG support.
* Said OTG shenanigans are so far supported on devices with debugfs & the chipidea driver, or sunxi devices.
* 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.
The ultimate goal is for toast widgets (i.e., Notification when flagged as such) to:
* Not stop event propagation
* Close themselves when the event was emitted by user input.
Instead of doing event filtering in UIManager, we simply overload the onGesture & onKey* handlers in Notification to do just that, and just make sure UIManager will *send* those events to toasts, but without affecting the usual semantics of top widget selection and event propagation (which is as simple as just calling handleEvent on them unchecked ;p).
Thanks to @poire-z for the brainstorming in https://github.com/koreader/koreader/issues/9594 ;).
This also happens to fix a bug in which we might have looped on the top widget twice, because of an array vs. hash mishap ;).
Also, make sure references are actually dropped,
no matter how the widget is closed, by relying on onCloseWidget ;).
Enable the "long-press-on-close" trick on the actual Close button,
too, instead of only on the title bar's cross.
Fix: https://github.com/koreader/koreader/pull/9586#issuecomment-1272332275
* Persist: support serpent, and use by default over dump (as we assume consistency > readability in Persist).
* Logger/Dbg: Use serpent instead of dump to dump tables (it's slightly more compact, honors __tostring, and will tag tables with their ref, which can come in handy when debugging).
* Dbg: Don't duplicate Logger's log function, just use it directly.
* Fontlist/ConfigDialog: Use serpent for the debug dump.
* Call `os.setlocale(C, "numeric")` on startup instead of peppering it around dump calls. It's process-wide, so it didn't make much sense.
* Trapper: Use LuaJIT's serde facilities instead of dump. They're more reliable in the face of funky input, much faster, and in this case, the data never makes it to human eyes, so a human-readable format didn't gain us anything.
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.
* UIManager: Support more specialized update modes for corner-cases:
* A2, which we'll use for the VirtualKeyboards keys (they'd... inadvertently switched to UI with the highlight refactor).
* NO_MERGE variants of ui & partial (for sunxi). Use `[ui]` in ReaderHighlight's popup, because of a Sage kernel bug that could otherwise make it translucent, sometimes completely so (*sigh*).
* UIManager: Assorted code cleanups & simplifications.
* Logger & dbg: Unify logging style, and code cleanups.
* SDL: Unbreak suspend/resume outside of the emulator (fix#9567).
* NetworkMgr: Cache the network status, and allow it to be queried. (Used by AutoSuspend to avoid repeatedly poking the system when computing the standby schedule delay).
* OneTimeMigration: Don't forget about `NETWORK_PROXY` & `STARDICT_DATA_DIR` when migrating `defaults.persistent.lua` (fix#9573)
* WakeupMgr: Workaround an apparent limitation of the RTC found on i.MX5 Kobo devices, where setting a wakealarm further than UINT16_MAX seconds in the future would apparently overflow and wraparound... (fix#8039, many thanks to @yfede for the extensive deep-dive and for actually accurately pinpointing the issue!).
* Kobo: Handle standby transitions at full CPU clock speeds, in order to limit the latency hit.
* UIManager: Properly quit on reboot & exit. This ensures our exit code is preserved, as we exit on our own terms (instead of being killed by the init system). This is important on platforms where exit codes are semantically meaningful (e.g., Kobo).
* UIManager: Speaking of reboot & exit, make sure the Screensaver shows in all circumstances (e.g., autoshutdown, re: #9542)), and that there aren't any extraneous refreshes triggered. (Additionally, fix a minor regression since #9448 about tracking this very transient state on Kobo & Cervantes).
* Kindle: ID the upcoming Scribe.
* Bump base (https://github.com/koreader/koreader-base/pull/1524)
* This removes support for the following deprecated constants: `DTAP_ZONE_FLIPPING`, `DTAP_ZONE_BOOKMARK`, `DCREREADER_CONFIG_DEFAULT_FONT_GAMMA`
* The "Advanced settings" panel now highlights modified values in bold (think about:config in Firefox ;)).
* LuaData: Isolate global table lookup shenanigans, and fix a few issues in unused-in-prod codepaths.
* CodeStyle: Require module locals for Lua/C modules, too.
* ScreenSaver: Actually garbage collect our widget on close (ScreenSaver itself is not an instantiated object).
* DateTimeWidget: Code cleanups to ensure child widgets can be GC'ed.
* ImageViewer: Minor code cleanups
* GestureDetector: Fix the `distance` field of `two_finger_pan` & `two_finger_swipe` gestures so that it's no longer the double of the actual distance traveled. Get rid of existing workarounds throughout the codebase that had to deal with this quirk.
Should avoid egregious values that would potentially alloc insanely large buffers (and likely fail to do so).
In the process, tweak the scale_factor computations when zooming so as to produce slightly less annoying behavior.
Get a Lua userdata wrapping a crengine LVSvgImageSource object
when long-press on a SVG image, and have crengine/LunaSVG render
it smoothly scaled to the requested size by ImageViewer.
