Alternative code to size 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
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).
Avoid saving/getting "12.0" (as the lua-ljsqlite3 driver does),
and save/get "12" instead by properly converting it to a string
and back, as the config.value table column is of type TEXT.
* 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 ;).
- Use a hardcoded default value of 10 files per page.
- Save cover sizetag as "s<nb of items per page>" instead
of "s<item height>" so they are stable (and not re-fetched)
when switching between FileBrowser and History, which have
some small geometry differences.
- When showing History in landscape mode, decrease perpage
from the set value, so items don't look smaller.
- Use a step, larger with big items, when iterating and decreasing
font sizes to make text fit, to speed up the process a bit.
(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.
* Made Porting not so hilariously outdated.
* Minor tweaks to the macOS build instructions and the various quirks involved in getting it to behave (and accompanying actual build fixes).
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 @
