Add a left button to the title bar to show the list
of results as a popup.
Dictionary: tap or long-press on that button give
different view of the results.
Wikipedia: request 30 results instead of 20, so we
can show 15, 10 or 6 of them per page of that popup.
For example, to determine whether the Japanese or Chinese form should be shown.
* Dictionaries.lua - use iso3 codes everywhere
readerdictionary.lua - convert iso to bcp tag, to construct ifo_lang
isolanguage.lua - map from iso3 to full language name, map from iso3 to bcp language tag
* Make the full language names translatable
* Store ifo information from dictionaries.lua in downloaded dictionaries
Re: https://github.com/koreader/koreader/issues/9806#issuecomment-1416827447
Depends on https://github.com/koreader/koreader-base/pull/1576
Includes assorted cosmetics tweaks related to duplicate `setDirty` calls when instantiating widgets that already have an `onShow` handler doing it. (I left widgets doing it in `update` instead of `init` alone, on the assumption that callers *may* be relying on that behavior when updating widgets at runtime. This might actually never matter, and it certainly didn't for ScreenSaverWidget, which is why I removed it from there ;p).
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).
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
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.
* Rejig frontlight warmth API to more closely match the existing API, and, hopefully, clarify some of its quirks, and reduce boilerplate and duplicate code in platform implementations.
* Tweak Kindle:setDateTime to prefer using the platform's custom script, as in interacts better with the stock UI. And make the fallbacks handle old busybox versions better.
* Add Kindle PW5 support ;).
* Add warmth support to the Kindle platform.
* Random TextBoxWidget cleanups: make sure we immediately free destroyed instances.
* FrontLightWidget: Refactor to make it slightly less obnoxious to grok and update; i.e., separate layout from update, and properly separate brightness from warmth handling. Move to simpler widgets instead of reinventing the wheel.
* TextBoxWidgets: Implement `setText` to match TextWidget's API, as some callers may be using the two interchangeably (i.e., Button).
* NaturalLightWidget: Make sure we pass a string to InputText
* InputText: Add debug guards to catch bad callers not passing strings ;).

Fix various issues with stacked Wikipedia lookup results,
and follow up lookups when invoked from Wikipedia lookup
history (where going to a search for language LL would
not use language LL when hitting "Full wikipedia").
Also tweak ReaderHighlight:onHoldRelease() to avoid
doing its stuff when onHold() is clearing highlight
(previous CheckButton was closing/clearing on hold
release, new TitleBar close button does that on hold).
There were two ways of specifing selected text for a highlight depending
on whether it was a "single word" or text selected using hold-and-pan.
In addition to being a bit more complicated than is necessary, with the
addition of the language support plugin system (where the "single word"
selected might be expanded), it makes more sense to simply use the same
logic and table structure for both cases.
The dictionary lookup special case (hold-without-pan triggering a
dictionary lookup by default) still works as before.
In addition, this patch fixes a minor inefficiency during dictionary
quick lookup -- before this patch, the highlight would be re-selected
because the quick lookup window is run concurrently and tries to fetch
ReaderHighlight.selected_text but this is set to nil immediately after
triggering the lookup. This is unnecessary because :clear() will be
called anyway when the quick pop-up closes, and so clearing this can be
left until then.

The hyphenation of a word can be changed from its default
by long pressing for 3 seconds and selecting 'Hyphenate'.
These overrides are stored in a per-language file, i.e:
koreader/settings/user-German.hyph.
That seems like a rather terrible idea to beign with, and that that may actually have fatal consequences.
Re #7738
Co-authored-by: Frans de Jonge <fransdejonge@gmail.com>
- TextWidget: avoid crash with small max_width (could happen
when opening menu on a small emulator window)
- TextWidget: avoid crash if re-used after :free()
- ReaderHighlight:clear(): fix possible crash when
scheduled and run after document closed
- DictQuickLookup: minor canSearch() tweak ('selected_text'
is normally available only on multiple words selection,
but is currently available on single word selection thanks
to some unrelated side effect)
* Ensure that going from one to the other tears down the former and
its plugins before instantiating the latter and its plugins.
UIManager: Unify Event sending & broadcasting
* Make the two behave the same way (walk the widget stack from top to
bottom), and properly handle the window stack shrinking shrinking
*and* growing.
Previously, broadcasting happened bottom-to-top and didn't really
handle the list shrinking/growing, while sending only handled the list
shrinking by a single element, and hopefully that element being the one
the event was just sent to.
These two items combined allowed us to optimize suboptimal
refresh behavior with Menu and other Menu classes when
opening/closing a document.
e.g., the "opening document" Notification is now properly regional,
and the "open last doc" option no longer flashes like a crazy person
anymore.
Plugins: Allow optimizing Menu refresh with custom menus, too.
Requires moving Menu's close_callback *after* onMenuSelect, which, eh,
probably makes sense, and is probably harmless in the grand scheme of
things.
* Input: Don't create a new TimeVal object for input frame timestamps, just promote our existing table by assigning it the `TimeVal` metatable.
* TimeVal: Export (const) `zero` & `huge` TimeVal objects, because they're common enough in our codebase. (NOTE: not actually const, that's a Lua 5.4 feature ;p).
* GestureDetector: Explain the behavior of the `last_tevs` & `first_tevs` tables, and why one needs a new object and not the other.
* Speaking of, simplify the copy method for `first_tevs`, because it doesn't need to create a new TimeVal object, we can just reference the original, it's unique and re-assigned for each frame.
* Change 'Find a file' to 'File search' for consistency
There is 'File search' in the Gesture manager already.
There is 'Fulltext search' in the readermenu.
Some help text added.
* ReaderDictionary: Port delay computations to TimeVal
* ReaderHighlight: Port delay computations to TimeVal
* ReaderView: Port delay computations to TimeVal
* Android: Reset gesture detection state on APP_CMD_TERM_WINDOW.
This prevents potentially being stuck in bogus gesture states when switching apps.
* GestureDetector:
* Port delay computations to TimeVal
* Fixed delay computations to handle time warps (large and negative deltas).
* Simplified timed callback handling to invalidate timers much earlier, preventing accumulating useless timers that no longer have any chance of ever detecting a gesture.
* Fixed state clearing to handle the actual effective slots, instead of hard-coding slot 0 & slot 1.
* Simplified timed callback handling in general, and added support for a timerfd backend for better performance and accuracy.
* The improved timed callback handling allows us to detect and honor (as much as possible) the three possible clock sources usable by Linux evdev events.
The only case where synthetic timestamps are used (and that only to handle timed callbacks) is limited to non-timerfd platforms where input events use
a clock source that is *NOT* MONOTONIC.
AFAICT, that's pretty much... PocketBook, and that's it?
* Input:
* Use the <linux/input.h> FFI module instead of re-declaring every constant
* Fixed (verbose) debug logging of input events to actually translate said constants properly.
* Completely reset gesture detection state on suspend. This should prevent bogus gesture detection on resume.
* Refactored the waitEvent loop to make it easier to comprehend (hopefully) and much more efficient.
Of specific note, it no longer does a crazy select spam every 100µs, instead computing and relying on sane timeouts,
as afforded by switching the UI event/input loop to the MONOTONIC time base, and the refactored timed callbacks in GestureDetector.
* reMarkable: Stopped enforcing synthetic timestamps on input events, as it should no longer be necessary.
* TimeVal:
* Refactored and simplified, especially as far as metamethods are concerned (based on <bsd/sys/time.h>).
* Added a host of new methods to query the various POSIX clock sources, and made :now default to MONOTONIC.
* Removed the debug guard in __sub, as time going backwards can be a perfectly normal occurrence.
* New methods:
* Clock sources: :realtime, :monotonic, :monotonic_coarse, :realtime_coarse, :boottime
* Utility: :tonumber, :tousecs, :tomsecs, :fromnumber, :isPositive, :isZero
* UIManager:
* Ported event loop & scheduling to TimeVal, and switched to the MONOTONIC time base.
This ensures reliable and consistent scheduling, as time is ensured never to go backwards.
* Added a :getTime() method, that returns a cached TimeVal:now(), updated at the top of every UI frame.
It's used throughout the codebase to cadge a syscall in circumstances where we are guaranteed that a syscall would return a mostly identical value,
because very few time has passed.
The only code left that does live syscalls does it because it's actually necessary for accuracy,
and the only code left that does that in a REALTIME time base is code that *actually* deals with calendar time (e.g., Statistics).
* DictQuickLookup: Port delay computations to TimeVal
* FootNoteWidget: Port delay computations to TimeVal
* HTMLBoxWidget: Port delay computations to TimeVal
* Notification: Port delay computations to TimeVal
* TextBoxWidget: Port delay computations to TimeVal
* AutoSuspend: Port to TimeVal
* AutoTurn:
* Fix it so that settings are actually honored.
* Port to TimeVal
* BackgroundRunner: Port to TimeVal
* Calibre: Port benchmarking code to TimeVal
* BookInfoManager: Removed unnecessary yield in the metadata extraction subprocess now that subprocesses get scheduled properly.
* All in all, these changes reduced the CPU cost of a single tap by a factor of ten (!), and got rid of an insane amount of weird poll/wakeup cycles that must have been hell on CPU schedulers and batteries..
* LuaSettings/DocSettings: Updated readSetting API to allow proper initialization to default.
Use it to initialize tables, e.g., fixing corner-cases in readerFooter that could prevent settings from being saved.
(Fixes an issue reported on Gitter).
* LuaSettings/DocSettings: Add simpler API than the the flip* ones to toggle boolean settings.
* Update LuaSettings/DocSettigns usage throughout the codebase to use the dedicated boolean methods wher appropriate, and clean up some of the more mind-bending uses.
* FileChooser: Implement an extended default exclusion list (fix#2360)
* ScreenSaver: Refactor to avoid the pile of kludges this was threatening to become. Code should be easier to follow and use, and fallbacks now behave as expected (fix#4418).
ScrollTextWidget
Despite a similar API between ScrollTextWidget and ScrollHtmlWiget, what
they do internally doesn't quite match.
So, while ScrollHtmlWidget's resetSCroll *does* rewind back to the top,
ScrollTextWidget's doesn't, it just updates the scrollbar itself.
So, do that on our end, *before* the (re-)init, which'll call
_renderText for us.
Fix#7318
* Simplify flash_ui handling (by handling the unhighlight pre-callback, c.f., #7262 for more details).
* UIManager: Handle translucent window-level widgets (and those wrapped in a translucent MovableContainer) properly in setDirty directly, making sure what's *underneath* them gets repainted to avoid alpha layering glitches. (This was previously handled via localized hacks).
* Update UIManager's documentation, and format it properly for ldoc parsing, making the HTML docs more useful.
* ReaderView: Reinitialize the various page areas when opening a new document, to prevent poisoning from the previous document.
* Event: Handle nils in an event's arguments.
* CheckButton/RadioButton: Switch to simple inversion to handle highlighting
* CheckButton: Make the highlight span the inner frame's width, instead of just the text's width, if possible.
* AlphaContainer: Fix & simplify, given the UIManager alpha handling.
* MovableContainer: When translucent, cache the canvas bb used for composition.
* Avoid spurious refreshes in a few widgets using various dummy *TextWidgets in order to first compute a text height.
* KeyValuePage: Avoid floats in size computations.
* DictQuickLookup: Preserve alpha when switching dict, and scrolling
inside a dict.
* Start moving the NumberPicker alpha hack to Button itself
This makes handling flash_ui easier and saner, avoiding flickering.
* Handle the transparency hack entirely from within Button
* Murder the now unnecessary NumberPicker update_callback hack
* Tweak comments
* And the Button handling made that redundant, too
* Squish debug print
* More comment tweaks
* Reset transparency on scrolling instead of rpeserving it
* Reset alpha when switching dictionaries
* Simplify the pre/post callbakc transparency state handling
And explain why we need to care.
* Give a named reference to ButtonDialog's MovableContainer, so the Button
alpha hack behaves with it
* Document the "self.movable" convention
* Amend that comment a bit
e.g., we don't care much about MultiConfirmBox'w MpvableContainer, as
any button action will close it.
* And make SkimTo's MovableContainer accessible so that Button can grok
that it's translucent
* Switching between HTML/text dicts (Fix#7209)
* Updating the scrollbar and scroll state properly when switching dicts
* Highlights in SortWidget
* Highlights in the Dictionary Download page
* Minor simplification of the tail end of the update process in ImageViewer
* QuickDictLookup, ImageViewer, NumberPicker: Smarter `update` that will re-use most of the widget's layout instead of re-instantiating all the things.
* SpinWidget/DoubleSpinWidget: The NumberPicker change above renders a hack to preserve alpha on these widgets almost unnecessary. Also fixed said hack to also apply to the center, value button.
* Button: Don't re-instantiate the frame in setText/setIcon when unnecessary (e.g., no change at all, or no layout change).
* Button: Add a refresh method that repaints and refreshes a *specific* Button (provided it's been painted once) all on its lonesome.
* ConfigDialog: Free everything that's going to be re-instatiated on update
* A few more post #7118 fixes:
* SkimTo: Always flag the chapter nav buttons as vsync
* Button: Fix the highlight on rounded buttons when vsync is enabled (e.g., it's now entirely visible, instead of showing a weird inverted corner glitch).
* Some more heuristic tweaks in Menu/TouchMenu/Button/IconButton
* ButtonTable: fix the annoying rounding issue I'd noticed in #7054 ;).
* Enable dithering in TextBoxWidget (e.g., in the Wikipedia full view). This involved moving the HW dithering align fixup to base, where it always ought to have been ;).
* Switch a few widgets that were using "partial" on close to "ui", or, more rarely, "flashui". The intent being to limit "partial" purely to the Reader, because it has a latency cost when mixed with other refreshes, which happens often enough in UI ;).
* Minor documentation tweaks around UIManager's `setDirty` to reflect that change.
* ReaderFooter: Force a footer repaint on resume if it is visible (otherwise, just update it).
* ReaderBookmark: In the same vein, don't repaint an invisible footer on bookmark count changes.
* I'd failed to notice that ButtonTable *also* instantiates seven billion Buttons on each update. Unfortunately, that one is way trickier to fix properly, so, work around its behavior in Button. (This fixes multiple issues with stuff using ButtonTable, which is basically anything with a persistent set of buttons. A good and easy test-case is the dictionary popup, e.g., the Highlight button changes text, and the next/prev dic buttons change state. All that, and more, was broken ;p).
* Handle corner-cases related to VirtualKeyboard (e.g., Terminal & Text Editor), which screwed with both TouchMenu & Button heuristics because it's weird.
* Flag a the dictionary switch buttons as vsync
(They trigger a partial repaint of the dictionary content).
* Flag the ReaderSearch buttons as vsync
They very obviously trigger a partial repaint, much like SkimTo ;p.
Restore feature removed in c98dfef7: tap on title
to set dict of current result as a preferred dictionary
for this document.
Changes from former implementation:
- trust sdcv for ordering, instead of doing it ourselves
by looking at the results (which didn't always work)
- allow setting multiple preferred dicts
- order of preference is shown with a number as a prefix
to the dictionary name in the title
- taping again allows removing it from preferred dicts,
and taping again allows setting it back as the first
preferred dict
Don't cleanup input text as much when entered manually
(or when it's sane) than when coming from book text
selection.
This may allow looking up words like "-suffix", or
do more precise Wikipedia queries.
- Rework widget layout to avoid implicit (and wrong)
sizing, using proper padding/margins and correct
measurements of components.
- Adjust lookup word font size so it's not smaller
than the definition.
- Tweak small window positionning: keep it centered
if possible, only move it to keep the highlighted
word shown when we can.
- Large window: adjust to screen size correctly,
leaving room for footer.
- Always have a "Close" button at bottom right.
Former always displayed button "Follow link" will
be added as a 3rd row in the rare case we select
a word in a link.
- Replace "tap on lookup word to edit and redo the
query" with an icon on the right: tap on it to
edit the queries word, long-press to edit the
current result word. Only close the current dict
window when lookup is launched.
- Remove feature "tap on title to set current dict
as the default dict for this document", as it didn't
really work, and it was bad UX.
- InfoMessage: add an option show_delay.
- MovableContainer: avoid possible crash when
not yet painted.
- ReaderDictionary: use show_delay=0.5 instead of
scheduleIn(0.5n...) (a5b133da) as we need the
InfoWidget to be known to UIManager to catch tap
and allow interrupting lookups properly.
- ReaderDictionary: rework handling of no_refresh_on_close
(6162c287) with proper regions comparisons
* ReaderDictionary: Don't refresh when dimissing the lookup info
InfoMessage
Re #6932
* Fix dict_largewindow in Landscape
Have to leave some room for the UI chrome
Since 8815cbe0 and getSafeFilename() taking additional
parameters, and :gsub() returning multiple values,
filesystem type wasn't really checked and replacements
were not ensured, so saving articles like "Portal:Stuff"
failed on VFAT devices as ':' wasn't replaced.
The default left margin on blockquote and dd is `40px`, but unfortunately that doesn't scale. rem is calculated using a hardcoded16px, so em or % is the best compromise in this case.
PS If we assume 1em = 16px then 40px is actually 2.5em, not 1em. This reduction in indentation is mainly intended for the benefit of smaller E Ink devices.
Closes <https://github.com/koreader/koreader/issues/5859>.
