Only available with EPUBs containing 2 or more fragments,
and a file size large enough to ensure a cache file is used.
The idea is simply, on any rendering setting change, to
skip the rerendering of the full book and to defer any
rerendering to the moment we draw a DocFragment, and
render only it.
So, on a setting change, only the fragment containing the
current page will be rerendered, and the new fragments we
may cross while turning pages.
When having done so, KOReader is in a degraded state (the
full page count is incorrect, the ToC is invalid...).
So, a full rerendering is needed, and one will happen
in the background, and when the user is idle, we reload
seamlessly and quickly from the cache file it has made.
ReaderFlipping will show some icons in the top left
corner to let it know at which steps in this procress
we are.
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.
Allow associating a font to each of the generic
font-family names.
Bump crengine:
- CSS parsing: accept (and ignore) namesspaces
- isImage(): more checks for <object> as it can have inner content
- getFontFileNameAndFaceIndex(): returns if font has math support
- getFontFileNameAndFaceIndex(): returns if font has emojis
- CSS/Fonts: add support for font-family to font name mapping
* 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.
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.
* Android: Make sure sdcv can find the STL
* DocCache: Be less greedy when serializing to disk, and only do that for the *current* document ;).
* CanvasContext: Explicitly document API quirks.
* Fontlist: Switch the on-disk Persist format to zstd (it's ever so slightly faster).
* Bump base for https://github.com/koreader/koreader-base/pull/1515 (fix#9506)
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.
Build crengine against LunaSVG instead of NanoSVG.
Includes:
- SerialBuf: allow serializing longer strings
- Support '<img src="data:image/svg+xml,<svg...', remove ;-cr-plain,
- CSS: attribute selectors: accept ' or " as the quote char
- Embedded fonts: fix ignored name when sharing same url
- LVImg: fix possible crash on GIF images
- Fonts: DrawTextString(): allow collecting glyphs as SVG paths
- Images parsing: cache native sizes
- SVG: enhanced SVG support with LunaSVG extended
- Add ldomNode::isImage(), handle <object> and <embed> as images
- Handle the <svg> element as an SVG image
- Support SVG images as first class documents
Make credocument the preferred engine for .svg files.
It is used by CoverBrowser, in a subprocess, when extracting
metadata from PicDocuments, and crash on Android as calling
android methods is only allowed from the main thread.
Includes:
- Text: fix possible overflow with "white-space: pre"
- Fonts: getFontFileNameAndFaceIndex(): return family type
- Fonts: account for _bias in Font hash
- epub.css, fb2.css: remove hardcoded monospace font names
- Fonts: allow scaling monospace fonts
- Fonts: allow adjusting fallback font sizes to x-height
- HTML parser: trust xml encoding before html charset
In our list of fonts, show a "M" indicator alongside
monospace fonts, and allow long-press to select the one
to be use for "font-family: monospace".
Add 2 options to Font settings, to scale monospace fonts
by a percentage, and to adjust fallback fonts to their
x-height.
Have the enabled/disabled state of the toggle show the
presence or not of embedded fonts in the current book.
Also show the names of the embedded fonts in the
help_text InfoMessage.
When selected text seems to be a "sentence segment"
(that is, when there are punctuations around start
AND end), extend the selection to include the relevant
punctuation.
Do this only when saving highlights and for translation
(but not when dict or wikipedia lookups, or search).
The setting is handled like all other bottom menu options
but, as it's really not useful and its target audience is
very limited, make it not shown in the bottom menu, but
available via another button in the (also quite not useful)
Word Expansion fine tuning widget.
Make it a real Document property, updated at init & toggle time.
Also, simplify a bunch of redundant nested lookups in ReaderView
(self.ui.view is self, self.ui.document is self.document).
- Add new strikeout highlight style.
- Fix highlight style in pdf documents (save_document enabled)
not updated when KOReader highlight style changed.
- Fix ugly combination of mupdf and KOReader highlights
Avoids requring Device direction in Document.
The method needs complete access to the Device object, though, so it's
just another layer of indirection, with an extra reference on the Device
object stashed in CanvasContext...
(much like it already does for Screen)
* TileCache: Preserve BlitBuffer's inversion & rotation
This somehow fell through the cracks for all these years ;).
(We can't simply save the config field directly, because bb.fromstring
always generates an allocated bb, which may not be the case of the
source bb).
* Bump base

Previously getTextFromBoxes would just pass the first and last three
bytes of the current and previous words when trying to detect CJK
characters (which shouldn't have spaces inserted).
However, this handling was not correct because CJK characters can be
longer than 3 bytes, and internally BaseUtil.utf8charcode doesn't ensure
that it was only given a single utf8 character (it blindly does the bit
operations on whatever length code you give it).
As a result, before this patch selections in PDF documents would have
lots of spaces stripped because getTextFromBoxes would think that almost
all characters were CJK characters.
Fixes: 6f1b70e5eb ("util.utf8: improve CJK character detection")

The second argument is a ddjvu_render_mode_t
Try to actually honor the user settings instead of enforcing COLOR
while we're there.
Fix#8376
Regression since #8250
There were a handful of cases where if there was no cached kctx there
was no fallback and several KoptInterface methods would return nil,
causing issues in various parts of KOReader (this happened with the
migration to selected_text everywhere but it's unclear how that change
caused this regression).
In any case, from a correctness perspective it makes sense to have the
corresponding fallback paths to create a new kctx if we couldn't find a
cached one.

With the latest koreader-base update, we can now create native
selections using getTextFromXPointers. In order to make the wrapper less
annoying to use, always enable segmented selection if selections are
enabled (to match getTextFromPositions).

It is a bit cleaner to do all of the necessary looping over lists of
Geoms within a straight-forward Geom.boundingBox function rather than
looping over :combine every time (or reimplementing :combine in some
cases). Geom:combine can be trivially reimplemented in terms of
Geom.boundingBox as well.

cores
* Only keep a single core online most of the time.
* Device: Add an enableCPUCores method to allow controlling the amount of
online CPU cores.
* Move the initial core onlining setup to Kobo:init, instead of the startup script.
* Enable two CPU cores while hinting new (e.g., cache miss) pages in PDF land.
* Enable two CPU cores while processing book metadata.
* Drive-by fix to isolate the DocCache pressure check to KoptInterface
and actually apply it when it matters most (e.g., k2pdfopt stuff).
* Geom:transformByScale:
* Apply the right scaling factor to the y axis
* Round in a more sensible fashion (àla fz_round_rect, since we pretty much exclusively use it in a similar fashion).
* Bump base (https://github.com/koreader/koreader-base/pull/1407)
TileCacheItem: add created_ts property.
Document: manage a tile_cache_validity_ts and ignore
older cached tiles.
This timestamps is updated when highlights are written
as annotations in, or deleted from, the PDF, so we can
get the most current rendered bitmap from MuPDF and
avoid highlight ghosts on old tiles.
Save this timestamp in doc settings so older cached to
disk tiles will also be ignored across re-openings.
Bump base for: mupdf.lua: update frontend pboxes with
MuPDF adjusted ones.
We may get multiple boxes when selecting texts, one for each
word, and we have to add spaces between the extracted words
ourselves. Previously, we were only adding a space if the
last char of previous word was ASCII, so missing spaces
after accents or greek words.
Try to do better by measuring the distances between boxes
and comparing to box heights, with a few heuristics.
Bump base for cre.cpp cleanup and utf8proc FFI.
Add a checkbutton for case sensitive search in FileBrowser,
and use Utf8Proc.lowercase() for case insensitive search.
Also use it in ReaderUserHyph as a replacement for
crengine getLowercasedWord().
- bump crengine: findText(): add support for regular
expression search.
- bump base: add thirdparty/srell/srell.hpp, a C++ library
that provides Unicode regex support, used by crengine.
- ReaderSearch: with credocuments, add checkboxes for case
sensitive and regular expression search.
I've encountered an issue when Calibre Content Server's OPDS feed produced ``text/fb2-xml`` mimetype. Don't know if it is actually Calibre to blame, but thought this simple fix will save some poor souls' time.
