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.
* Various FocusManager related tweaks to limit its usage to devices with a DPad, and prevent initial button highlights in Dialogs on devices where it makes no sense (i.e., those without a DPad. And even on DPad devices, I'm not even sure how we'd go about making one of those pop up anyway, because no Touch ;)!).
* One mysterious fix to text-only Buttons so that the flash_ui highlight always works, and always honors `FrameContainer`'s pill shape. (Before that, an unhighlight on a text button with a callback that didn't repaint anything [say, the find first/find last buttons in the Reader's search bar when you're already on the first/last match] would do a square black highlight, and a white pill-shaped unhighlight (leaving the black corners visible)).
The workaround makes *absolutely* no sense to me (as `self[1] -> self.frame`, AFAICT), but it works, and ensures all highlights/unhighlights are pill-shaped, so at least we're not doing maths for rounded corners for nothing ;).
Feature of ScrollTextWidget, only used for now by TextEditor.
Pan is like Swipe, but wait a bit at end of gesture to release:
the line on which Pan was started will be moved to where Pan is
released.
May conflict with MovableContainer (so not enabled for DictQuickLookup,
where it could have been nice - but it would work only with text
dictionaries, not with HTML ones, as ScrollHtmlWidget can't really
do that).
This plugin mostly sets up a "Text editor>" submenu, that allows
browsing files, creating a new file, and managing a history of
previously opened file for easier re-opening.
It restore previous scroll and cursor positions on re-opening.
Additional "Check lua" syntax button is added when editing
a .lua file, and prevent saving if errors.
The text editing is mainly provided by the enhanced InputDialog.
InputDialog: added a few more options, the main one being
'save_callback', which will add a Save and Close buttons
and manage saving/discarding/exiting.
If "fullscreen" and "add_nav_bar", will add a show/hide keyboard
button to it.
Moved the preset buttons setup code in their own InputDialog
methods for clarity of the main init code.
Buttons are now enabled/disabled depending on context for feedback
(eg: Save is disabled as long as text has not been modified).
Added util.checkLuaSyntax(lua_string), might be useful elsewhere.
* Make findcalibre actually useful
By setting SEARCH_LIBRARY_PATH when a Calibre tree is found, so that
book paths can properly be constructed.
Users should still very much set it themselves, but at least everything
works as intended when not, instead of mysteriously half-breaking later.
Drop the SetDefaults bits, it appeared to have been added to fix no-ops
detected by Luacheck, and it's actually non-functional, because
SetDefaults doesn't handle saving variables it did not itself assign.
So this was just causing the "Do you want to save new defaults" popup to
show up on exit, but it couldn't actually do anything useful (like, say,
save the new SEARCH_LIBRARY_PATH value).
fix#4082
* Better comments about the state of NaturalLight on the Clara, and how this might translate to the H2O²r2.
re #4015
* Make ScrolltextWidget refresh as "partial" only on actual Scroll events
Moving the cursor should stay "ui", or things gets annoying really fast
;).
re #4084
* Bump base to pickup ZMQ fixes (fix#4086)
InputText, ScrollTextWidget, TextBoxWidget:
- proper line scrolling when moving cursor or inserting/deleting text
to behave like most text editors do
- fix cursor navigation, optimize refreshes when moving only the cursor,
don't recreate the textwidget when moving cursor up/down
- optimize refresh areas, stick to "ui" to avoid a "partial" black
flash every 6 appended or deleted chars
InputText:
- fix issue when toggling Show password multiple times
- new option: InputText.cursor_at_end (default: true)
- if no InputText.height provided, measure the text widget height
that we would start with, and use a ScrollTextWidget with that
fixed height, so widget does not overflow container if we extend
the text and increase the number of lines
- as we are using "ui" refreshes while text editing, allows refreshing
the InputText with a diagonal swipe on it (actually, refresh the
whole screen, which allows refreshing the keyboard too if needed)
ScrollTextWidget:
- properly align scrollbar with its TextBoxWidget
TextBoxWidget:
- some cleanup (added new properties to avoid many method calls), added
proxy methods for upper widgets to get them
- reordered/renamed/refactored the *CharPos* methods for easier reading
(sorry for the diff that won't help reviewing, but that was needed)
InputDialog:
- new options:
allow_newline = false, -- allow entering new lines
cursor_at_end = true, -- starts with cursor at end of text, ready to append
fullscreen = false, -- adjust to full screen minus keyboard
condensed = false, -- true will prevent adding air and balance between elements
add_scroll_buttons = false, -- add scroll Up/Down buttons to first row of buttons
add_nav_bar = false, -- append a row of page navigation buttons
- find the most adequate text height, when none provided or fullscreen, to
not overflow screen (and not be stuck with Cancel/Save buttons hidden)
- had to disable the use of a MovableContainer (many issues like becoming
transparent when a PathChooser comes in front, Hold to paste from
clipboard, moving the InputDialog under the keyboard and getting stuck...)
GestureRange: fix possible crash (when event processed after widget
destruction ?)
LoginDialog: fix some ui stack increase and possible crash when switching
focus many times.
(each one at top right of each page)
Such images can be loaded dynamically when the display of a page requires it.
Allow alternating between the image and its title with Tap on it.
Allow for viewing this image zoomed in ImageViewer with Hold on it.
DictQuickLookup: add generic support for result.images, that
could optionally be provided in Wikipedia lookup results.
util: made isSplitable() accept an optional next_char
for wiser decision
textboxwidget: speed up rendering, enhanced text wrapping,
allow selection of multiple words with Hold.
scrolltextwidget: allow scrolling with Tap.
Details in #2393
And fix several other bugs introduced in #2028:
1. hint messages are back instead of the "Demo hint"
2. cursor now only presents in the focused inputbox in a multiinput dialog
3. moving cursor now works in multiinput dialog
This is a major overhaul of the hardware abstraction layer.
A few notes:
General platform distinction happens in
frontend/device.lua
which will delegate everything else to
frontend/device/<platform_name>/device.lua
which should extend
frontend/device/generic/device.lua
Screen handling is implemented in
frontend/device/screen.lua
which includes the *functionality* to support device specifics.
Actually setting up the device specific functionality, however,
is done in the device specific setup code in the relevant
device.lua file.
The same goes for input handling.
colors were a mixture of 4bpp integers (0=white, 15=black) and
fractional blackness levels (0=white, 1.0=black) before. This is
now unified to use the color specification of the Blitbuffer API.
This should finish the work to make all globals to local variables.
That allows LuaJIT to properly compile things by interning the
references to the relevant parts (rather than looking up globals
all the time which stops a trace).
