A Minecraft plugin with a Math DSL

I hate pulling out my calculator to do math for my redstone projects

fn slope(m,x,b) = m*x+b;
slope(1,5,2)

Usage

/eval <program>

Features

• Add, subtract, multiply, divide numbers in the minecraft commandline.
• Create simple functions to remove redundant routines.
• Bind native functions
  • sin,cos,min,max, and more!
  • PR's needed to add more.

Syntax :

Program

A program consists of zero or more functions and an optional expression. If no expression exists, 0 is the result.

Functions

fn ident(id, id1, id2) = expr

fn ident() = expr

Expressions

Basically, any math calculator

1 + 2 - 5

Function calls

sin(rad(0)) 

• yields .49999

Constants

Built in constants are PI, E, CHUNK

• A CHUNK is 16 ( in minecraft )

Developing

• This is a gradle project, and two main scripts exist
