CraftOS-PC v2.5.3

A bug in v2.5.2 and early releases of v2.5.3 on Windows prevents the installer from being launched automatically. If you are on Windows, please either download this update manually, or auto-update, then navigate to C:\Users\<username>\AppData\Local\Temp, and run setup.exe.

CraftOS-PC v2.5.3 brings some big changes relating to the debug API, and fixes a large number of bugs. It also introduces a new crash report uploader that will automatically send crash dumps to be analyzed, allowing bugs discovered by users to be fixed without them having to manually file a bug report.

• Added automatic crash log uploading behind snooperEnabled (Windows only)
  • A prompt will appear on first boot asking to allow this
  • See https://www.craftos-pc.cc/docs/privacy for info about how your data is kept secure
• Added snooperEnabled config setting
  • This is currently only used for crash uploading, but more (very basic) analytics may be added in the future
• The debug API is now enabled by default
  • This is possible due to the debug API no longer requiring hooks
  • The availability of debug resolves a long-standing compatibility issue when run with the default config
• Bumped structure version to 2
  • New fields in configuration:
    • snooperEnabled
  • New fields in PluginFunctions:
    • registerConfigSetting
  • New fields in Terminal:
    • mouseButtonOrder
• Added new registerConfigSetting capability to allow access to plugin settings from config API
• Added ability to yield from line and count hooks
• Debug hooks now work as expected when no debugger is attached
  • This breaks logErrors and non-debugger breakpoints, but neither feature is used much
    • They may be brought back in the future, but they are not working for now
• Functions passed to load can now yield in standards mode only
  • This is behind standards mode due to the possible performance hit being higher than its usefulness
• Decreased mixer chunk size to 512
  • This should help with latency in things like the sound plugin
• Fixed HTTP handles not being closed when going out of scope/being deleted
• Fixed deadlock/high memory usage when resizing window to 0x0
• Fixed DPI issues in hardware renderer on Mac when switching between Retina and non-Retina displays
• Fixed deadlock when maximizing window with snapToSize enabled
• Fixed mouse buttons > 3 being returned as 1
• Mouse buttons > 3 no longer report in standards mode
• Fixed the order of mouse buttons reported with mouse_drag when multiple are down at the same time
• Fixed crash when loading plugin config
• Fixed plugin config not saving properly
• Fixed \ not being treated as a directory separator
• Fixed /\.{3,}/ not being treated the same as .
• Fixed fs.getCapacity in standards mode
• Rewrote abort timeout handling to no longer use debug hooks
• Changed size_t size in binary Lua chunks to 4 bytes for compatibility
• Added lua_externalerror to throw errors from another thread
• Improved performance of internal string split function

• Errors now appear if mounting/unmounting fails
• Increased maximum call stack height to 2000, allowing more nested coroutines/function calls
• __len metamethods can now yield as expected
• getNextEvent now checks the parameter stack's size before creating a new stack
• Made some minor improvements to fixpath

  • This is the REAL issue that v2.5.1.1 was supposed to fix - the fix didn't work on macOS
• Fixed key_up not firing for some keys in raw mode
• Fixed modulo operator returning unexpected results
• Fixed os.startTimer firing immediately when time < 0.05 in standards mode

CraftOS-PC v2.5

Merry Christmas (to those who celebrate it)! This year, Santa has brought you a fresh new version of CraftOS-PC, featuring a huge amount of bugfixes, with plenty of new features mixed in. The main feature is full compatibility with not just CC: Tweaked 1.94.0 (which was missing from the last update), but also 1.95.0 which just came out today (as of writing)! This is accomplished with the new ROM that is entirely based on CC:T's copy, no longer using the old CC 1.8 codebase. There's also a new plugin API, offering much better stability and opportunity for expansion, as well as some nice features such as CLI mode support for Windows.

• Reorganized code structure for easier maintenance of the codebase
  • Code has been divided between APIs, peripherals, renderers, and general functions
  • Resolved a large number (>1000) of warnings
  • Reduced usage of extern to headers only
  • Made all non-global variables static
• Rebased ROM on the CC: Tweaked ROM
  • The ROM is now equivalent to the CC: Tweaked ROM with additional CraftOS-PC features from the old ROM
  • With this, the CC:T Edition has been discontinued
    • It wasn't really necessary anyway
  • This should help improve compatibility in the ROM
• Updated CC:T version to 1.95.0
  • 1.94.0
    • Add getter for window visibility (devomaa)
    • Use term.blit to draw boxes in paintutils (Lemmmy).
    • Fix several programs using their original name instead of aliases in usage hints (Lupus590).
  • 1.95.0
    • Clear gets an option to reset the palette (Luca0208)
    • Use term.blit on initial paint render.
    • Add option to disable setting globals (Lupus590).
    • Fixed length check on function name in expect (MCJack123)
    • Allow strings or numbers in textutils.*tabulate.
    • Make fs.combine accept multiple arguments.
    • Added improved help viewer (MCJack123)
    • Added numpad enter support (TheWireLord).
    • Add functions to wrap text (Lupus590)
• Added new plugin API
  • API version has now been bumped to 10
  • New plugin init/deinit functions: PluginInfo * plugin_init(const PluginFunctions * functions, const path_t& path); & void plugin_deinit(PluginInfo * info);
  • Capabilities in the old API are now present as function pointers in the PluginFunctions structure passed to plugin_init
  • Additional functions are now available as well:
    • Access to the configuration, including custom settings for plugins
    • SDL event hooks
    • Virtual mounts
    • Running tasks on the main thread
  • See https://www.craftos-pc.cc/docs/plugins for more info on how to write plugins
• Added release note viewer
• Added support for CLI mode on Windows through PDCurses
• Added optional width and height options to term.drawPixels
• Added term.getPixels to read a region of pixels (LoganDark)
• Added optional solid color fill argument to term.drawPixels (LoganDark)
• Added some missing HTTP configuration options (besides black/whitelist)
• Added a panic handler that is more like ComputerCraft's in standards mode
• Added force-shutdown functionality when a computer refuses to close
• Added error handlers when an uncaught exception occurs
  • This should not happen, but if it does CraftOS-PC will no longer fully crash
• Added tracing of the last C Lua function called, hopefully helping memory corruptions be able to be fixed
• Optimized scroll and clear routines to directly copy memory
• Fixed os.setAlarm implementation to no longer use 100% CPU
• Fixed unknown config options being deleted
• Fixed close button and hotkeys not functioning when there are too many events in the queue (#154)
• Fixed monitor.setTextScale not functioning properly with non-6x9 fonts (#150)
• Fixed term.getPixel returning the wrong values in mode 1 (#159)
• Fixed a race condition while resizing when using the hardware renderer
• Fixed a race condition in os.startTimer
• Fixed a possible race condition when firing a timer
• Reduced the number of event timeout timers started when pulling events (#158)
  • This fixes an issue causing the timer thread to lock up trying to process start/cancel events
• Fixed some locking issues in terminals
• Fixed missing range checks in term.drawPixels
• Fixed term.getPixel crashing when accessing pixel at edge of screen (LoganDark)
• Fixed some issues with resizing the debugger
• Fixed computers hanging when closing the debugger on Linux (#157)
• Fixed debugger locals table sometimes not functioning properly
• Fixed some CraftOS-PC term functions being redirected (LoganDark)
• The craftos2-lua library can now be used in programs other than CraftOS-PC
• Windows: Standalone builds have been replaced with portable ZIP packages
  • These function the same, but now also support plugins, the HD font, and other things previously not available
• Mac: Made the icon a bit smaller to fit the general macOS app icon template
