This is a tool that calculates the chunk boundary coordinates of a chunk by providing a pair ofX,Z coordinates within that chunk in Minecraft.

This is 1.0.0.0 of the 3rd version/rewrite; the 1st is written in AutoHotkey and for Windows only, sorry if that bothers you lol. The second is written in Python, cross-platform for Windows and Linux and this is the cross-platform CLI version of this 3rd version written in Rust.

Here you will find 2 Linux files: an installable .deb package and a portable .AppImage and 1 Windows portable executable. For more ways to use this and more information check out the project at:
