- height_adjust: if true, reduce height to a multiple of
line_height (for nicer centering)
- height_overflow_show_ellipsis: if height overflow, append
ellipsis to last shown line
(Implemented in both use_xtext and legacy code path.)
Use them in Menu.lua to clean up/shorten the code used for multiline
menu items by delegating the work to TextBoxWidget, or using
TextWidget when we end up needing only a single line.
Alternative code to size, split lines and draw text with
the help of the xtext Lua C module.
Enabled by default (can be disabled via an added menu
item in "Developer options").
New properties can be specified by calling widgets, only
used when xtext is used:
- lang: use specified language instead of the UI language
- para_direction_rtl: true/false to override the default
direction for the UI language
- auto_para_direction: detect direction of each paragraph
in text
- alignment_strict: prevent the inversion of the specified
alignment= that is done when a paragraph direction is
set or detected as RTL.
Also: fix possible memory leak (present even when not using xtext)
by calling :free() in onCloseWidget() like it's done in ImageWidget.

bump base for libkoreader-xtext.so:
- ffi/pic.lua: fix memory leak with some unsupported PNG files
- FreeType ffi: add methods for use with Harfbuzz shaping
- thirdparty: adds libunibreak
- Adds libkoreader-xtext.so: enhanced text shaping
Add a getFallbackFont(N) to each Lua font object to instantiate
(if not yet done) and return the Nth fallback font for the font.
Fallback fonts list: add NotoSansArabicUI-Regular.ttf
Add RenderText:getGlyphByIndex() to get a glyph bitmap by glyph
index, which is what we'll get from Harfbuzz shaping.
(RenderText:getGlyph() works with unicode charcode).
Tapping to turn page while some image is loading was
interrupting the image loading, but not turning the page,
since a82d7832 where using trap_widget=false is to be
used to not resend the event (while =nil does resend it).
It might be slower, but is needed to properly display
books in arabic, indic...
Also bump crengine: use FreeType "light" hinting algorithm,
which hints on the y-axis only (and so avoid messing with
advances and kerning on the x-axis).
* Restore '+' prefix when charging in the footer w/ letters prefixes
Regression since #5537
* Don't use a full battery icon in the menu entry
Make it clear that one isn't in-sync with the current gauge
* Unify battery meters look'n feel
Switch to proper (vertical) battery icons (one per 10% steps).
Fix#5535
* Bump fonts (https://github.com/koreader/koreader-fonts/pull/7)
Because we need the new symbols from nerdfonts ;).
(used by bookmarks list and classic file browser)
When text is too long or line too tall:
first: we try to decrease the number of lines (eg from 3 to 2 and from 2 to 1 line)
second: when 1 line is too tall, we try to decrease font size (-1)
And at the end we try to add or remove chars to better fit text.
Lots of code was doing some renderText calls to get the size
of some text string, and truncate it to some width if needed,
with or without an added ellipsis, before instantiating
a TextWidget with that tweaked text string.
This PR fixes/adds some properties and methods to TextWidget
so all that can be done by it. It makes the calling code
simpler, as they don't need to use RenderText directly.
(Additionally, when we go at using Harfbuzz for text rendering,
we'll just have to update or replace textwidget.lua without
the need to update any higher level code.)
Also:
- RenderText: removed the space added by truncateTextByWidth
after the ellipsis, as it doesn't feel needed, and break
right alignment of the ellipsis with other texts.
- KeyValuePage: fix some subtle size and alignment issues.
- NumberPickerWidget: fix font size (provided font size was
not used)
* Changed File Browser text
KOReader looks nicer than KOReader File Browser,
* Remove the "page x of x" if only one page
Removes it from the bottom of the file browser
* Remove the "page x of x" if only one page
Removes it from the top menu, if there is only one page, why show page 1 of 1
* Renamed ~ to Home
Since the file browser can be considered "Home"
* Added 12 hour time option
Also tweaked the charging icon, ⚡ looks nicer than +, tweaked seperator between time and battery, - instead of @
Includes:
- (Upstream) Unified cache for chars and glyph's indexes
- (Upstream) Glyph caching: optional use of hash table instead of a linked list
- (Upstream) Adds docx and fb3 support
- Update hardcoded elements list and stylesheets
- DocX: build a HTML DOM instead of a FB2 DOM
- Text: allow wrap after '/' and '-'
- Text: with Harfbuzz, split measurement on text node change
- Clear fonts on load and re-rendering
With some particular document switching workflows, the
screensaver menu could lose its last item, and shrink
to having zero item, and eventually cause a crash.
* Don't break `doc_pages` updates when it's completely disabled. (c.f., the commit's comment, doing it on every page turn seems a bit overkill, but I get that it's probably done that way because it was easier ;)).
* Detect the empty footerTextGenerator properly in `_updateFooterText` (it's `""`, not `nil`).
* Abort `_updateFooterText` early when the footer is invisible (and has been for a while/ever, i.e., when not requesting a repaint, like a mode switch would).
* Never send `SetBottomPageMargin` events twice.
* Minor tweaks to touchmenu & configdialog to avoid useless repaints (don't redraw the reader/fm unless we absolutely need to).
* Make sure we show the progress bar alone instead of nothing when disabling the last enabled mode in the menu.
Tap any part of screen to toggle bottom buttons visibility.
Swipe south to quickly close it (as long as image is scaled
to fit, and there's no need for panning).
bump crengine: enhanced RTL block rendering.
Includes:
- Re-enable: Use the same FT load flags in HB as in FT
- Avoid redundant calls to getStyle()
- CSS: parse and store "direction:"
- Enhanced block rendering: handle RTL direction
- Enhanced block rendering: handle RTL tables
- Pagesplitting: account for lines' text direction
- CSS: add support for more pseudo-classes
- epub.css: a few updates for RTL documents
- Fix LVDocView::getBookmark() which could be slow or wrong
Add a few style tweaks useful to RTL readers.
Wikipedia Save as EPUB: build proper RTL documents from
persian, arabic, hebrew (and others) Wikipedia articles.
sysfs_light handles every case sanely already, no need to be cute ;).
This prevents always setting the warmth when setting the FL on NL
devices with a mixer, because, besides being useless, it's also slow
(lua does mmap'ed io, so every handle requires an fstat + mmap).
It was subtly affecting the fluidity of the toggle ramp, and much less
subtly wreaking havoc on #5373 ;).
KA1 owners might want to investigate keeping the fds around one way or
another, like we do for the fl ioctl, to alleviate the overhead of doing
that for not one but three or four fds...
I won't be doing that, since I lack the hardware to test it, and FL+NL
stuff is pain.
* Do the same on Cervantes
* Bump base to pickup related ioctl tweaks
Includes:
- Adds tinyNodeCollection::getStatistics()
- epubfmt.cpp: cleanup indentation and small optimisation
- Add more progress callback events
- Optimisation: avoid re-init for EPUBs with embedded fonts
- Fix: don't draw border when border-color: transparent
- CSS: ignore 'inherit' inside font-family
Show a small progress meter at top left of screen when
crengine is loading, re-rendering, and saving cache file
(after a 2 second delay to not be bothered on small books).
Also add a wrapper for the last remaining bit of code that
was accessing _document directly (:getPageOffsetX()).
When reasonably possible, the program should only crash in debug mode.
Adds a couple of extra unit tests to prevent regressions and adds docs.
Fixes <https://github.com/koreader/koreader/issues/5356>.
