William Dummy Lang

My dummy programming language that compiles specific syntax arithmetical expressions to JavaScript expressions. I just did this as compilers training.

Operators

• sub - Subtract
• sum - Sum
• mult - Multiply
• div - Divide

Syntax

(operator ...args[] | (operator ...args[]))

Example

(sum 2 (sub 4 3 1)) // Equivalent to (4 - 3 - 1 ) + 2

Usage

Install dependencies

npm install

Compiling

Source file

Path: ./examples/simple.dml

Content:

(sum 2 (sub 4 3 1))

Compile command

npm run compile ./examples/simple.dml

Compiled file

Path: ./examples/simple.js

Content:

2 + (4 - 3 - 1);

Executing

Source file

Path: ./examples/simple.dml

Content:
