HexDebug
A Hex Casting addon for debugging and editing hexes. The Debugger runs a debug server using the Debug Adapter Protocol, allowing you to use real debugging tools like VSCode to find bugs in your hexes; and the Splicing Table provides an easy-to-use GUI for finding and fixing mistakes.

Features
- Debugging: Step through your hexes pattern-by-pattern with vscode-hex-casting or any other DAP-compatible editor!
- Editing: Use the Splicing Table to edit hexes just like in a text editor, with buttons and keyboard shortcuts to select, move, duplicate, delete, and copy/paste iotas, and even draw patterns in a mini staff grid.
- Step Modes: Use any of the well-known step modes (step in/out/over, continue, restart, stop) with the ingame item and/or through VSCode.
- Variables: See the stack, ravenmind, and even some internal values like the evaluated pattern count.
- Call Stack: Debug complex meta-evaluating hexes with the call stack, generated from the next continuation to be executed. Learn how Hex Casting's internals work!
- Breakpoints: Set breakpoints on specific patterns, or use the Uncaught Mishaps option to pause the debugger when a mishap occurs and see what went wrong.
- Multiplayer: Debug your hexes in multiplayer! The debug client connects to a port opened by the game client (configurable, defaults to 4444), and each player can have up to one active debugger instance at a time.
