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.
* 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).
Tweak building to start from items per page instead of
a fixed item height.
Guess the best font size that fit.
Update separator specification from using a "----" to
the now generic separator=true (this allows not wasting
a slot for each separator in the page and not have
only 12 items and 2 small lines in a 14 items page).
* Avoid the Lua string copies when compressing/uncompressing the bb
thumbs
* Delay the statement reset so that the pointer returned by the BLOB
query is actually usable ;).
* Re-use a ZSTD decompression context
* Store date & mtime for successfully extracted documents
c.f., 10477501f9 (r44914917)
* Switch to user_version pragma to handle DB schema versioning
* Update file size/date on *each* extraction attempt.
@poirez-z raised a good point, this ought to be useful to deem a file
re-parseable after an update.
* Remove xutil
Functionality has been moved to ffi/zlib & ffi/zstd
* Preserve settings when migrating the BookInfo DB
* Warn via InfoMessage that the DB was updated
* Only store the series name in series, and move the index in series_index
(Column names chosen to match Calibre's).
* Handle the new series_index column in BookInfo consumers
* This allows us to get rid of the code that stripped empty decimals
from series index in *most* places, since it's now a real Lua
number, and the string formatting library does that magic on its
own.
Gives the book language to Text*Widget (and XText) when
drawing title, authors and other metadata text.
Might be needed to properly display a Japanese book title
when the UI language is Chinese.
bidi.lua:
- Revert "Alias everything to Bidi.nowrap() when in LTR UI,
as using LTR isolates seems uneeded when already LTR" (part
of a628714f) which was a wrong assumption: we need proper
wrappers for all things paths. Enhance some of these wrappers.
- Fix GetText RTL wrapping which was losing empty lines and
trailing \n.
- Wrap all paths, directories, filenames in the code with
these wrappers.
- Wrap all book metadata (title, authors...) with BD.auto(),
as it helps fixing some edge cases (like open/close quotation
marks which are not considered as bracket types by FriBiDi).
(Needed some minor logic changes in CoverBrowser.)
- Tweak hyphenation menu text
- Update forgotten SortWidget for UI mirroring
- KoptConfig: update "justification" index for RTL re-ordering,
following the recent addition of the page_gap_height option.
Code removed from ReaderGesture and put into BookInfo where
it belongs, so we can just use Events.
Also convert description to plain text to not show HTML tags.
cre:loadDocument() may fail in recognizing the document format, and
koreader would previously keep calling other methods on it, which would
make crengine segfaults. We now check loadDocument success at the
various places it is called, and try to deal the best way we can when it fails.
So an image file can have a cover in coverbrowser's display.
It also allows for an alternative viewer (ImageViewer widget)
when holding on file / View full size cover.
