There have been a couple of these this month, and keeping stuff that should only ever run once piling up in their respective module was getting ugly, especially when it's usually simple stuff (settings, files).
So, move everything to a dedicated module, run by reader.lua on startup, and that will actually only do things once, when necessary.
Attempting to update a highlight when matching on a bookmark doesn't
make sense, and no longer works since #7411
Also, switch to ipairs(), and stop piggybacking on a new local that
shadows or uses the function's item argument.
It works in Lua, but it's super weird and error-prone.
Fix#7520 (regression since #7411).
Generic feature added to TouchMenu: an optional callback
'open_on_menu_item_id_func()' set on an items table can
tell which menu item should be shown when opening a menu.
TouchMenu: allows jumping to first or last page with
long-press on the chevrons.
* Change 'Find a file' to 'File search' for consistency
There is 'File search' in the Gesture manager already.
There is 'Fulltext search' in the readermenu.
Some help text added.
It appears the fancy split settings from #6885 were not being honored at all.
Also:
* Made sure "pagewidth" is actually the default zoom mode again, "full" had sneaked in as the default state of the zoom type toggle).
* Display human-readable values in the "Make as default" popup, instead of the raw, meaningless numerical setting.
* Disable zoom options when reflow is enabled, and restore 'em properly when it's disabled.
Fix#7461, #7228, #7192
* ReaderDictionary: Port delay computations to TimeVal
* ReaderHighlight: Port delay computations to TimeVal
* ReaderView: Port delay computations to TimeVal
* Android: Reset gesture detection state on APP_CMD_TERM_WINDOW.
This prevents potentially being stuck in bogus gesture states when switching apps.
* GestureDetector:
* Port delay computations to TimeVal
* Fixed delay computations to handle time warps (large and negative deltas).
* Simplified timed callback handling to invalidate timers much earlier, preventing accumulating useless timers that no longer have any chance of ever detecting a gesture.
* Fixed state clearing to handle the actual effective slots, instead of hard-coding slot 0 & slot 1.
* Simplified timed callback handling in general, and added support for a timerfd backend for better performance and accuracy.
* The improved timed callback handling allows us to detect and honor (as much as possible) the three possible clock sources usable by Linux evdev events.
The only case where synthetic timestamps are used (and that only to handle timed callbacks) is limited to non-timerfd platforms where input events use
a clock source that is *NOT* MONOTONIC.
AFAICT, that's pretty much... PocketBook, and that's it?
* Input:
* Use the <linux/input.h> FFI module instead of re-declaring every constant
* Fixed (verbose) debug logging of input events to actually translate said constants properly.
* Completely reset gesture detection state on suspend. This should prevent bogus gesture detection on resume.
* Refactored the waitEvent loop to make it easier to comprehend (hopefully) and much more efficient.
Of specific note, it no longer does a crazy select spam every 100µs, instead computing and relying on sane timeouts,
as afforded by switching the UI event/input loop to the MONOTONIC time base, and the refactored timed callbacks in GestureDetector.
* reMarkable: Stopped enforcing synthetic timestamps on input events, as it should no longer be necessary.
* TimeVal:
* Refactored and simplified, especially as far as metamethods are concerned (based on <bsd/sys/time.h>).
* Added a host of new methods to query the various POSIX clock sources, and made :now default to MONOTONIC.
* Removed the debug guard in __sub, as time going backwards can be a perfectly normal occurrence.
* New methods:
* Clock sources: :realtime, :monotonic, :monotonic_coarse, :realtime_coarse, :boottime
* Utility: :tonumber, :tousecs, :tomsecs, :fromnumber, :isPositive, :isZero
* UIManager:
* Ported event loop & scheduling to TimeVal, and switched to the MONOTONIC time base.
This ensures reliable and consistent scheduling, as time is ensured never to go backwards.
* Added a :getTime() method, that returns a cached TimeVal:now(), updated at the top of every UI frame.
It's used throughout the codebase to cadge a syscall in circumstances where we are guaranteed that a syscall would return a mostly identical value,
because very few time has passed.
The only code left that does live syscalls does it because it's actually necessary for accuracy,
and the only code left that does that in a REALTIME time base is code that *actually* deals with calendar time (e.g., Statistics).
* DictQuickLookup: Port delay computations to TimeVal
* FootNoteWidget: Port delay computations to TimeVal
* HTMLBoxWidget: Port delay computations to TimeVal
* Notification: Port delay computations to TimeVal
* TextBoxWidget: Port delay computations to TimeVal
* AutoSuspend: Port to TimeVal
* AutoTurn:
* Fix it so that settings are actually honored.
* Port to TimeVal
* BackgroundRunner: Port to TimeVal
* Calibre: Port benchmarking code to TimeVal
* BookInfoManager: Removed unnecessary yield in the metadata extraction subprocess now that subprocesses get scheduled properly.
* All in all, these changes reduced the CPU cost of a single tap by a factor of ten (!), and got rid of an insane amount of weird poll/wakeup cycles that must have been hell on CPU schedulers and batteries..
* Add a new socketutil module with a few helper functions that allow us to:
* Always use a sane User-Agent (previously, only Wikipedia did so)
* Set timeouts in an almost sane manner. Doing it explicitly prevents an interaction with KOSync that does crazy stuff I don't even want to try to understand.
* Unified said timeouts based on the request's intended usage (except for Wikipedia, which already had meaningful timeout values).
* Stopped using LuaSec directly, LuaSocket defers to LuaSec sanely on its own. Everything now transparently supports HTTPS without code duplication.
* Screensaver: Unbreak screensaver_stretch_images
We don't have real ternary operators in Lua, if the second argument evaluates to false, it doesn't work.
Invert the test to avoid this pitfall.
(c.f., http://lua-users.org/wiki/TernaryOperator).
Fix#7402, regression since #7371
* Free a few similar constructs (incidentally, some of 'em also tweaked in #7371 ^^).
* LuaSettings/DocSettings: Updated readSetting API to allow proper initialization to default.
Use it to initialize tables, e.g., fixing corner-cases in readerFooter that could prevent settings from being saved.
(Fixes an issue reported on Gitter).
* LuaSettings/DocSettings: Add simpler API than the the flip* ones to toggle boolean settings.
* Update LuaSettings/DocSettigns usage throughout the codebase to use the dedicated boolean methods wher appropriate, and clean up some of the more mind-bending uses.
* FileChooser: Implement an extended default exclusion list (fix#2360)
* ScreenSaver: Refactor to avoid the pile of kludges this was threatening to become. Code should be easier to follow and use, and fallbacks now behave as expected (fix#4418).
Instead of piggybacking on InputContainer's onInput trickery for hold_input & tap_input.
Also, don't flag the buttons from that InputDialog as vsync, because that was stupid ;).
Fix#7357
* Menu/KeyValuePage/ReaderGoTo: Unify the dialogs. (Generally, "Enter page number" as title, and "Go to page" as OK button).
* Allow *tapping* on pagination buttons, too. Added spacers around the text to accommodate for that.
* Disable input handlers when <= 1 pages, while still printing the label in black.
* Always display both the label and the chevrons, even on single page content. (Menu being an exception, because it can handle showing no content at all, in which case we hide the chevrons).
* KVP: Tweak the pagination buttons layout in order to have consistent centering, regardless of whether the return arrow is enabled or not. (Also, match Menu's layout, more or less).
* Menu: Minor layout tweaks to follow the KVP tweaks above. Fixes, among possibly other things, buttons in (non-FM) "List" menus overlapping the final entry (e.g., OPDS), and popout menus with a border being misaligned (e.g., Calibre, Find a file).
* CalendarView: Minor layout tweaks to follow the KVP tweaks. Ensures the pagination buttons are laid out in the same way as everywhere else (they used to be a wee bit higher).
Tweak building to start from items per page instead of
a fixed item height.
Guess the best font size that fit.
Update separator specification from using a "----" to
the now generic separator=true (this allows not wasting
a slot for each separator in the page and not have
only 12 items and 2 small lines in a 14 items page).
Remove the title bar, as it was just taking uneeded
space over the book content.
Add a middle button in the top row to toggle bookmark
for the current page.
Rework the UI building to get more consistent and
aligned buttons and progress bar.
Move SkimToWidget from apps/reader/ to ui/widgets/.
* Simplify flash_ui handling (by handling the unhighlight pre-callback, c.f., #7262 for more details).
* UIManager: Handle translucent window-level widgets (and those wrapped in a translucent MovableContainer) properly in setDirty directly, making sure what's *underneath* them gets repainted to avoid alpha layering glitches. (This was previously handled via localized hacks).
* Update UIManager's documentation, and format it properly for ldoc parsing, making the HTML docs more useful.
* ReaderView: Reinitialize the various page areas when opening a new document, to prevent poisoning from the previous document.
* Event: Handle nils in an event's arguments.
* CheckButton/RadioButton: Switch to simple inversion to handle highlighting
* CheckButton: Make the highlight span the inner frame's width, instead of just the text's width, if possible.
* AlphaContainer: Fix & simplify, given the UIManager alpha handling.
* MovableContainer: When translucent, cache the canvas bb used for composition.
* Avoid spurious refreshes in a few widgets using various dummy *TextWidgets in order to first compute a text height.
* KeyValuePage: Avoid floats in size computations.
* In ReaderPaging, the panning step pre-PanningUpdate can be wildly overshot near page edges, so, use the corrected value instead by recomputing it after the panning has been effectively computed by ReaderView.
This fixes slight inaccuracies, as well as glaring mistakes when going backwards, or when near page edges.
This is in line with how ReaderRolling computes the value, which I only realized later because I'm an idiot.
* Minor cleanups around the handling of the dim_area Geom object in general.
* Fix the "Arrow" page overlap mode to be painted in the right coordinates when going backward. Issue might not have been terribly clear because of the previous issue ;).
* Center the arrow's point, while we're here.
* Don't use AlphaContainer to make it translucent, because AlphaContainer is horribly broken, and has weird quirks and behavior that make no sense to me unless some very specific and unlikely constraints are met, and they definitely aren't here.
This fixes the arrow copying an arrow-sized square of the original page the book was opened on on the top-left corner of *every* page with an arrow. (lol).
* Do real proper alpha-blending via Icon/ImageWidget from the original icon, instead of faking it via addBlitFrom, in order to avoid the dimming *around* the triangle's shape.
- Menu widget: allow specifying the number of items per
page and the item font size, so we can use other values
than the default File browser ones
- Menu: fix setDirty when a border is used
- ToC: add item per page and font size settings, make
Alternative ToC more visible (was previously
available on long-press on Table of contents)
- Bookmarks: add item per page, font size, size reduction
- Progress bars (Skim widget and footer): allow selecting
ToC depths from which ticks are made.
When opening a document in scroll mode with an invalid
last_xpointer.
This code path was never taken before 05126b94, and it has
never been updated to pass the page number in scroll mode
(so it's provided to the footer) like it has been in other
places.
Rework Dual pages code so that the view is considered
a single page number, so it looks more like 2-columns
on a single page.
This solves a few issues like:
- Page number and count are consistent between top
and bottom status bars
- SkimTo -1/+1 doing nothing every other tap
- Statistics being wrong (like "Pages read" never
going over half of the book page count)
