Math Lang

Toy scripting language to calculate math

How to Play

1. get the math-lang binary

Build binary from source

make sure you have installed git, cmake, any C++ build system (make by default), and any C++ compiler (g++, clang++, MSVC)

git clone https://github.com/revival0728/math-lang.git
cd math-lang 
cmake -B build -S . && cmake --build build --config Release -DBUILD_TESTS=OFF

Download from Release

You can download math-lang binary from Release page.

2. run the binary

./build/src/math-lang

Binary Usage

math-lang 
  [Math-Lang-Script File Path (.mls)]

Language Syntax

rnum = [raw-number] | [scientific-notation] | [[rnum]^[rnum]]
idnt = [user-defined-variable] | [builtin-constants] | [rnum]
oper = [+][-][*][/]
expr = [idnt] |
       [fun-call] |
       ([expr]) |
       [idnt][=][expr] |
       [expr][oper][expr] |
fun-call = [fun-name]([[expr] | [expr], ...])

The scripts execute based on expr.

You can checkout MLS script exmaples in the examples/ folder.
