Changelog

Additions

Pattern language refactor and editable data inspector

Changelog

Addition

• Added basic editing support to the data inspector
  • Simply double click the type you want to edit and then enter your new value there
  • Not all types can currently be edited but the majority of it can

• Added help text to data processor to tell the user how to start using it

Pattern Language

• Massive refactor of the pattern language
  • The entire pattern language now switched to using smart pointers instead of doing manual memory management. This should prevent the majority of memory leaks that were present before.
• Allow all variable attributes to be applied to types directly so all their instances will have those attributes applied
• Added #pragma bitfield_order which applies the [[left_to_right]] or [[right_to_left]] attribute to all bitfields by default
• Added [[single_color]] attribute which forces all children of a pattern to have the same color. Thanks to @PredatorCZ

• Arrays and custom types are now properly getting treated as references so they can be passed to functions without getting weird behaviour
• Added std::mem::find_sequence_in_range. Thanks a lot to @PredatorCZ
  • This function works the same as std::mem::find_sequence but takes two additional parameters to specify the start and end address of the search performed
• Fixed off-by-one error when calculating unsized array sizes. Thanks to @Dyddye

Improvements

• Automatically disable borderless window mode then an Intel HD GPU is being detected.
  • This prevents the black boarder / offset rendering from appearing which is caused by a bug in the Intel OpenGL driver
  • This detection can be overwritten by manually setting the hex.builtin.setting.interface.force_borderless_window_mode setting to 1 in your settings.json
• Disable buffering on log files so their full content is always being written to disk
• Improved error handling of the content store
  • The content store now only tries to list files in folders that are actually writable
  • ImHex will no longer try to download (and fail) to download files into folders without permissions
• Increased store load timeout to 30 seconds
  • This should allow you to use the content store even if you're behind tons of proxies
• Improved ImHex restarting user experience
  • Instead of just immediately closing ImHex when a setting was changed that needed a restart, ImHex now correctly prompts if you want to restart it.
• Content from the ImHex-Patterns repository is now getting shipped by default
