gINVERT was inverting the wrong coordinates
Ensure the correct library section is selected when switching program
Remove search as it causes program layout issues on first run Unfortunately having a search controller in AllProgramsViewController was causing our UISplitViewController to get into a weird intiial state which was then leading to an overly large navigation bar when pushing ProgramViewController. That navigation bar was then occluding the top of the program’s RootView meaning it wasn’t possible to interact with the menu. This change removes search until we can find the issue with our use of UISplitViewController. THere’s a longer discussion on the issue tracking this: https://github.com/inseven/opolua/issues/206

Add Welcome app
Add support for viewing OPL files
Support hardware keyboard autorepeat
Add pull-to-refresh to allow users to manually trigger an update While it should only be necessary if the user has added large external locations and we’re unable to monitor directories for changes, this will allow users to manually trigger a refresh if things don’t look right, and serves as a bit of a get out of jail free card for our directory monitoring.
Support launching ‘applications’ from with OPL programs
Share text from the source viewer
Share images from MBM files
Add the most basic sound viewer

Automatically download iCloud Drive files so that they’re available when running programs
Don’t show configuration options for programs in readonly locations
Don’t show the console in the options menu Since we’re only showing crashes in the console, it doesn’t really make much sense to let users open it.
Navigating through directories can cause the app to crash We were leaking the Directory objects thanks to a non-weak delegate and therefore leaking all the file handles associated with the directory monitoring. It doesn’t take long for things to go south in this scenario.
Address OOM issues when changing indexable locations rapidly
Update ‘All Programs’ when files change and programs are installed
Add a dedicated icon for text files
System file system detection recurses infinitely #137
Disable partial Revo support on release builds
Unnecessary directory monitoring can lead to crashes
Don’t strip extensions from files
Reveal the newly installed program on successful installation
Use the localized error description for error alerts This switches back to using errorDescription and localizedDescription as the mechanism for getting localised descriptions for all error types. It tries to preserve the underlying behaviour of the new classes and adds slightly more user-friendly error messages for the database and unimplemented operation errors.
Ensure the source text view always bounce-scrolls vertically
Ensure silk-screen buttons gray out when the program terminates It turns out that the new UIButton.Configuration-based constructors will automatically gray out when disabled, so the only work to do to fix this issue was to switch to the new constructors
Out of range charcodes passed to CHR$()
tapdance the toolbar code to handle latching non-latchable buttons
Implement {OS,ROM}Version{Major,Minor,Build}
Implement GETEVENT() fixes #175
Implement SIDisplaySize, SIBatteryVolts
Rate limit rescans when files change
Don’t do unnecessary work when files change quickly This introduces a delay of 0.1s to ‘debounce’ any file change notifications. In my testing, it seems sufficient to ensure we don’t do more than one rescan during file writes.
Add dedicated sound and folder dark mode icons
Fail gracefully when attempting to monitor too many directories This introduces a hard limit to the number of directories we try to monitor, hopefully ensuring that we do not hit the OS limits for open file handles. When the limit is hit, all monitoring fails and will only restart when the application is relaunched. We don’t attempt a partial failure (failing just one observer) as it’s fiddly to fairly and effectively determine which observer contributes the largest number of directories and should be abandoned. In the long term we could try to do something clever, but that way madness lies.
Improve color icon shadow appearance in Dark Mode This change switches to using translucent shadows that replicate the same 33% gray used by the original icons to ensure they render well in both regular and dark mode.
Ensure programs from iCloud Drive automatically appear in ‘All Programs’
Address race conditions that could sometimes cause file changes to be missed This change switches to using a breadth-first approach to walking the directory tree, ensuring directory monitors are in place and started for a directory before descending into its sub-directories. This means we should no longer be at risk of missing intermediate changes between listing the directory structure and setting up monitors.
Don’t perform unnecessary rescans when files change This introduces a new class, RateLimiter, which makes it easy to schedule delayed updates and uses this in ProgramDetector and UbiquitousDownloader.
Directories and All Programs stop being able to detect changes
Don’t automatically create D drive folders during installation This change also disallows D drives in .system bundles to ensure we have the freedom to easily implement a shared D drive in the future.
Offer to raise GitHub Issues for internal errors and improve description template
don’t ignore TBarColor called after the toolbar has been set up
don’t use an unprotected call to write event data
toolbar redraw when TBarSetTitle is called after buttons are added
Workaround some drawing artifacts in border logic
Don’t apply key repeat to the menu key
Add empty icon to toolbar buttons without icons
Improve the appearance of Series 5 grayscale icons in dark mode This change makes the grayscale icon shadows translucent (33%) so they render correctly in dark mode. It also adds colour to the unknown application icon (to match the unknown file icon), and fixes a small image file detection regression.
Don’t scale-up small images in the image viewer
Correct margins on the image viewer cells
Cache directory items to improve performance
Use more targeted caches to ensure we don’t over cache file metadata Unfortunately this doesn’t offer anywhere near the same performance improvements we were seeing earlier but it does seem to speed things up by about 25%.
Don’t over-cache directory itmes for systems Previously we were failing to invalidate the cache when items in nested folders within systems changed. This introduces a new struct ApplicationMetadata which is essentially a tuple of the app info and its on-disk URL to allow us to key an icon cache by the AIF’s mtime.
Small aesthetic tweak to the unknown application icon
Correct definition of modulus to match OPL/C semantics
digital clock when time is between 12:00 and 13:00

Add the Wilhelm Scream to the example files and update the file names
Support for dialogs and choice items This includes some drive-by menu appearance fixes.
Support drawing lines and circles
Add basic iOS icon
Call specific procedures from the context menu This change introduces a context menu on library items and allows procedures to be called directly. It also includes a drive-by fix to add support for text input in dialogs.
Support dialogs with multiple buttons
Show directories in the library view This change updates LibraryViewController (now renamed to DirectoryViewController) to show directories and allow drill-down into directories. This should allow us to organise our (increasingly extensive) example code better in the future and prepares the way for adding user defined locations.
Top-level library view for listing different locations
Add locations from iOS file providers like iCloud Drive This is a first-cut attempt at supporting file providers in the top-level library.
Rudimentary support for event handling
Flesh out iOS touch events
Support cancelling asynchronous events
Toolbar buttons are functional
Support bitmap masks on gBUTTON/toolbar buttons
new memory model supporting addressof and arbitrary memory read/write
Beep beep beep!
Support the KEY opcode
App icons in the library views and launch as different devices
Separate console view controller This change moves the console into a separate view controller which we can use to add other debugging functions in the future. The implementation is incredibly basic at the moment, but hopefully sufficient for our needs.
Rudimentary support for gIPRINT and BUSY This also includes some drive-by refactoring to make it easier to reuse some of the graphics primitives, and a small bug fix in event cancellation.
Rudimentary support for software and hardware games controllers This currently has a hard-coded keymap for Jumpy!
Delete items and pull-to-refresh directories
Detect applications within full system directories
Browse package contents
Possibly functional installSisFile(path:) API
Use the host directory structure for system packages
Rudimentary installer support
bmp OPX
Rudimentary support for sprites This change pulls many of the graphics operations out of ProgramViewController and into a new WindowServer class. The ownership model is a little wrong right now, and there remain a number of bits of cleanup to do around sprites, not least honouring the animation timing.
gSETPENWIDTH
Alloc support
Support cancelling async events
Support for bitmap fonts specifically KFontDigital35
Background and restore running programs This change introduces TaskManager which tracks running programs and allows for navigating back to them. Right now, there’s no support for relaunching programs for different devices, meaning that if you run for a specific device, the program will run, but not be tracked by the task manager.
Quit running apps from the context menu
dumpmbm.lua and dumpaif.lua now export to .bmp rather than raw pixels
Support LoadRsc, ReadRsc, ReadRscLong, UnloadRsc
support gCOLORBACKGROUND() in its ER5 opcode value

Colour clock for Series 7
epoc-native menus
Hide/show the wallpaper This change also changes the default theme to the colour Series 7 theme.
Default controller mappings for Jumpy! and Asteroids This change introduces controller mapping lookup by UID3 and adds a default mapping to be used by all apps, and specific mappings for Jumpy! and Asteroids.
Store the clock type for all programs
Correct margins for the console output
Sort the OPO files by name using Finder sort This change also introduces a couple of convenience abstractions (OPLObject, and Library) to keep code out of the view controllers.
Don’t show the .opo extension in the library
Use an icon for the menu toolbar item
Pop the view controller when the program finishes
Rudimentary feedback that a menu item has a trailing separator This change also switches to using OptionSet for flags as it’s easier to query.
Button to dismiss the menu
Use application tint color for selectable menu items
Update the menu to match the latest iOS menu styles This change also combines the two menu view controllers into one.
Back the image rendering with a framebuffer for improved accuracy and performance
gCircle opcode
Line coords are absolute not relative
Text alignment in dialogs doesn’t work
Support cancelling dialogs
Support prompt and value in dialog text rows
Support the enter key in dialogs
Ensure only selectable text can be selected in dialogs
Text alignment should be limited to body text
Don’t synthesize a cancel button Leave it to the user to drag-to-dismiss if they want to cancel without tapping an explicit button. This far more closely matches the EPOC implementation. This change also leands more heavily on the drop-down menu for showing dialog options to simplify the code and prepare for showing buttons directly in the view.
Show all buttons at the bottom of dialogs
Support separators in dialogs
Ignore dot files
Show apps in directory listings
Correct the screen dimensions and position windows correctly This is a very small incremental change that explicitly disables layout constraints within CanvasView and adds the window subviews to the canvas view to avoid needing to use layout constraints (we really do want to manually control their absolute positions). It also hardcodes the dimensions of the canvas view to match the requested screen size, and puts the console below the screen. We’ll probably made different choices in the future, but this makes it much clearer where the screen bounds are and ensures the console isn’t obscured (or vice versa).
Don’t use interpolation when scaling the screen This change removes the UIImageView from CanvasView and instead uses core graphics to draw the view directly by blitting the contents of the canvas to screen. This keeps our view hierarchy simpler, and allows us to manually control how the bitmap is scaled to the view and disable interpolation (so we don’t get fuzzy pixels).
Grey out the text when the program has terminated This is a little more in-keeping with iOS.
Keep the console scrolled to the end
Assign the correct window identifier to touch events
Ensure the cancelled event type matches the request type
Set delegate on child CanvasViews
Use the new iOS toolbar button menus
Buffer touch and keyboard events This change also implements getch using the regular event queue and scheduler to support both GET and GETEVENTA32 menu implementations.
Implement the ASC opcode
Work-around the weird inability to dispatch to queues from within the Lua callbacks This is a really really hacky work-around to the apparent issue that we don’t have a fully functional GCD within the Lua callbacks. Right now it spins up a separate dispatch queue and and has this sit on a blocking concurrent queue which we dispatch async operations to from the Lua thread. This is only a proof of concept and should either be ripped out (if we can work out why GCD isn’t working correctly in the Lua callbacks), or replaced with an actual operation queue which we can manage more cleanly as part of a wider runtime.
