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.
Small tweaks all around to handle UI mirroring:
- swap existing symbols like arrows, or use alternative ones
- rotate some images, like chevrons and dogear icons
- flip some left and right swipe handling
- flip some geometry arithmetic like tap on left or right
side of page or dict window
- use new ProgressWidget:getPercentageFromPosition() instead
of geometry arithmetic
- BD.wrap() some concatenated string bits, like in reader
and menu footers
- flip inverse_reading_order when UI is mirrored
More specific tweaks:
- ReaderGesture: reset some specific gestures when UI direction
has changed (tap on top/bottom left/right corners, for
bookmarks and FileManager "Plus menu").
- ReaderRolling: show markers on the correct side of page,
in single or dual page mode.
- KoptOptions: swap left and right icons in Alignment toggle
- CheckMark: proper rendering in all 4 mirroring/rtl combinations.
- VirtualKeyboard: forbid any mirroring
- Move util.getMenuText into Menu.lua
Allow TextBoxWidget new text direction/lang parameters to be
set on upper widgets, and propagate them all the way to it
(ScrollTextWidget, InputText, InputDialog, TextViewer).
Use specific non-default ones in some specific cases:
- Force LTR text direction when showing HTML and CSS, and
configuration files (in some plugins).
- Use Wikipedia server language and text direction when
showing an article.
- Use auto with Dictionary results, as we don't know the
dictionary language, and they may contain mixed content.
- Force LTR when showing some paths (still needs more of them)
TextEditor plugin: add 2 new options "Auto paragraph direction"
and "Force paragraph direction LTR".
Footnotes popup: grab HTML direction, and forward it
to MuPDF for proper display.
This commit standardizes the various todos around the code a bit in a manner recognized by LDoc.
Besides drawing more attention by being displayed in the developer docs, they're also extractable with LDoc on the command line:
```sh
ldoc --tags todo,fixme *.lua
```
However, whether that particular usage offers any advantage over other search tools is questionable at best.
* and some random beautification
Bump crengine: background image and other fixes:
- View HTML: option to show text unicode codepoints
- Fix attribute parsing: decode &-encoded chars
- Text: allow wrap after more unicode spaces and hyphen
- Fix: no left hanging when hanging punctuation disabled
- lvtextfm.cpp: more comments, some formatting cleanup
- Optimize background image drawing
- CSS: fix background-image file path resolution
Bump luasec to 0.8.1
Bump harfbuzz to 2.6.0
cre.cpp:
Adds setBackgroundImage() proxy function to crengine
facility to set background textures (this is unrelated
to the background-image CSS fixes).
No frontend code (yet) to select such an image.
View HTML: adds a 3rd view (extended debug view), showing the
unicode codepoint of each char and crengine rendereing methods.
Similar to what's been added for 1 page view, but just turn
one page instead of switching to scroll mode when reaching
top left or bottom right corners.
Also make the selection start xpointer more accurate by
getting them in onHold(), instead of possibly too late in
onHoldPan() where we have already moved.
No need to use current page and xpointers. We can use
'pos', in both scroll and page modes, as it is always
accurate to show the y of the current view.
Also check for boxes in the 2nd page when in 2 page modes
(and fix onTapXPointerSavedHighlight(), too quickly cut
and pasted from drawXPointerSavedHighlight() recently).
Bump crengine and cre.cpp to correctly returns rect for
the first line of the 2nd page.
The idea of looking for highlights 1 page before and after
was not working when you have multiple small pages, and
some scroll mode view was actually showing 3 or 4 pages.
So, rework that by using absolute positions when looking
for highlights present in the scrolled view.
Panning to the bottom right corner (or top left corner) switches
to scroll mode and scroll the page forward (resp. backward) 1/3rd
of the screen.
One has to pan out of the corner to continue selection.
Panning again to that corner scrolls another 1/3rd of screen.
Page mode is restored when highlighting or dismissing the highlight
dialog, and a little marker is shown at where selection was started
so one does not get lost after all that scrolling and restoring.
Make this existing setting tunable with a menu item.
Also make the Page overlap and Highlight menus use a
checkbox, and their items grayed out when disabled.
Revert 9971eb85 and make multi-lines strings more readable.
(Multiline translatable strings extraction has been fixed
in koreader-misc tralua_xgettext.py.)
Update translator.lua to use a still working google translate API.
Add a method to show translations (main and alternates) in
a TextViewer.
Re-enable "Translate" button in text selection/highlight buttons
dialog.
Target language can be set with a manually added setting:
translator_target_language = "fr"
and will fallback to the UI language.
bump crengine, which includes:
- Adds support for symbol fonts (local or embedded)
- Fix some issues when rendering text in constrained width
- Page splitting: fix possible missing blocks
- CSS: adds support for 'auto', ignore % for borders
- Fix right border drawing position
- Fix: adds missing properties in copystyle()
- Adds comments, erm_killed rendering method
- Adds getRenderedWidths(): get node min/max node content width
- Tables rendering: fixes and improvements
- getRenderedWidths: enable min_width to be a single CJK char
- Fix wrong text wrap avoid in some case
- epub.css: add style for 'blockquote'
- Fix rendering issue when line ends with an image
Adds a few style tweaks related to tables.
Enforce table width: 100% in Wikipedia EPUBs to keep
previous look, which feels better with the various kinds
of tables in Wikipedia pages.
Fix unit tests as juliet.epub (full of blockquotes), grew quite
a few pages with the epub.css update.
Adds new options to the Links> submenu, for now only
available and used with CRE documents.
- Allow larger tap area around links
- Ignore external links
- Show footnotes in popup
- Show more links as footnotes
(This last item is mostly for testing and loosening the
footnote detection algorithm, and see how it would behave
with glossary-like links and inter glossary terms links.)
Fix distance computation from gesture position to link by
using segments.
Code for detecting if a link is a footnote is in cre.cpp, and
tweakable a bit with flags in ReaderLink:showAsFoonotePopup().
Footnotes HTML content is displayed by a new FootnoteWidget,
which uses MuPDF for its rendering.
From it, swipe south or tap outside to close, swipe to the left
to follow the original link and jump to the footnote location
in the book.
Also fix tap on highlights after the recent change to use segments
for displaying: use segments also when checking taps.
TouchMenu: added options to menu items with the following defaults:
keep_menu_open = false
hold_keep_menu_open = true
So, default for Tap callback is to close menu, and for Hold callback
to keep menu open.
In both cases, provide the TouchMenu instance as the 1st argument to
the callback functions (instead of a refresh_menu_func I added in #3941)
so the callback can do more things, like closing, refreshing,
changing menu items text and re-ordering...
ReaderZooming: show symbol for default (like it was done for
ReaderFont, ReaderHyphenation...)
TextEditor plugin: update the previously opened files list in real
time, so the menu can be kept open and used as the TextEditor main
interface.
SSH plugin: keep menu open and update the Start/Stop state in real time
ReadTimer plugin: tried to do what feels right (but I don't use it)
Also remove forgotten cp in the move/paste file code
Some problem somewhere with [[...]] strings starting with a
leading newline. Should probably be allowed, but for now
fix the few such cases to allow them being translated.
New module RenderImage (alongside existing RenderText) to provides
image rendering and scaling facilities.
Uses MuPDF, but tries first giflib on GIF.
Allows for getting all the frames from an animated GIF.
Holding on a word for more than 3s should bring the highlight menu.
It crashed on readerpaging documents because self.hold_pos is no more
a Geom object with them.
Also inverted selected_word/selected_text logic, as with PDF, selected_word
stays set when selected_text is available.
drawXPointerSavedHighlight() and onTapXPointerSavedHighlight were
looping thru all credocuments highlights, which was expensive.
Now, we first check with cheaper getPageFromXPointer() the highlights
are on the current page before doing more expensive stuff.
Closes#3503.
Also fix a few crash possibilities when unhighlighting.
Also fix bug with binary search that could not be able to remove bookmark
when there are multiple bookmarks/highlights on the same page.
This makes button heights similar in all uses of ButtonTable.
It depended on how the ButtonTable was used in each widget
(previously, first and last row may have different sizes than
the others).
buttontable.lua: more even buttons height whether zero_sep or not
framecontainer.lua: added padding_top/bottom/left/right (similar to
what was done for iconbutton)
The following widgets have been adapted for this, with some
additional fixes:
buttondialog.lua
buttondialogtitle.lua: wider title with adequate padding
confirmbox.lua + multiconfirmbox.lua: dismissable via tap outside
inputdialog.lua + multiinputdialog.lua: more even vertical padding between elements
imageviewer.lua
textviewer.lua
datewidget.lua
timewidget.lua
Additionaly: frontlightwidget.lua: fixed width of progress bar that
was exceeding window width since the Size scaling adjustements
