Keep things least likely to be terrible at being interactive shells
first ;).
We penalize ZSH a bit, because RPROMPTS aren't really handled by the
plugin, which makes things confusing.
This shall fix#12271
Use $SHELL env-variable if available. (thanks to @Frenzie)
Use a read line wrapper (either rlfe or rlwrap) if available so that dash can be used as interactive shell.
Basically:
* Use `extend` for class definitions
* Use `new` for object instantiations
That includes some minor code cleanups along the way:
* Updated `Widget`'s docs to make the semantics clearer.
* Removed `should_restrict_JIT` (it's been dead code since https://github.com/koreader/android-luajit-launcher/pull/283)
* Minor refactoring of LuaSettings/LuaData/LuaDefaults/DocSettings to behave (mostly, they are instantiated via `open` instead of `new`) like everything else and handle inheritance properly (i.e., DocSettings is now a proper LuaSettings subclass).
* Default to `WidgetContainer` instead of `InputContainer` for stuff that doesn't actually setup key/gesture events.
* Ditto for explicit `*Listener` only classes, make sure they're based on `EventListener` instead of something uselessly fancier.
* Unless absolutely necessary, do not store references in class objects, ever; only values. Instead, always store references in instances, to avoid both sneaky inheritance issues, and sneaky GC pinning of stale references.
* ReaderUI: Fix one such issue with its `active_widgets` array, with critical implications, as it essentially pinned *all* of ReaderUI's modules, including their reference to the `Document` instance (i.e., that was a big-ass leak).
* Terminal: Make sure the shell is killed on plugin teardown.
* InputText: Fix Home/End/Del physical keys to behave sensibly.
* InputContainer/WidgetContainer: If necessary, compute self.dimen at paintTo time (previously, only InputContainers did, which might have had something to do with random widgets unconcerned about input using it as a baseclass instead of WidgetContainer...).
* OverlapGroup: Compute self.dimen at *init* time, because for some reason it needs to do that, but do it directly in OverlapGroup instead of going through a weird WidgetContainer method that it was the sole user of.
* ReaderCropping: Under no circumstances should a Document instance member (here, self.bbox) risk being `nil`ed!
* Kobo: Minor code cleanups.
So we actually have a chance of understanding why it fails to load ;).
(Also, properly require posix FFI stuff, in the unlikely event they aren't already in the main namespace).
New real terminal emulator, replacing the old plugin.
The emulator is basically a vt52 terminal (enriched with
some ANSI-sequences, as ash, vi and mksh don't behave well
on a vt52 term).
So far working: ash, mksh, bash, nano, vi, busybox, watch...
The input supports: tab-completion; cursor movement;
backspace; start of line, end of line (long press);
page up, page down (long press).
User scripts may be placed in the koterm.koplugin/scripts/
folder, aliases can be put in the file aliases and startup
command in the file profile.user in that folder.
* 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).
- Show output in a TextViewer with a monospace font.
- Include stderr, so errors are shown
- Use Trapper to allow interrupting command (and to fix
some refresh issues)
