HexDebug
A Hex Casting addon for debugging and editing hexes.
Quick answer
Which HexDebug release should I use?
HexDebug 0.9.1+1.20.1 targets 1.20.1 with Forge. Installation on the client is optional. Installation on the dedicated server is optional. All 9 required mods have matching files.
Where it goes
Is HexDebug required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does HexDebug 0.9.1+1.20.1 need?
0.9.1+1.20.1. Change the file and its required mods may change too.
Install Hex Casting, Architectury API, Cloth Config API, Kotlin for Forge and 5 more first. We found matching files for this game-version and loader setup. 4 come through another mod in the chain.
4 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does HexDebug add?
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.
