Backstory

I wanted to make a gimmicky language but was too lazy to implement loops. So I made an event queue and throw pushes event to the queue and terminates current event. When the runtime reaches the end of the file, it runs the next thing off of the queue.

Syntax

Expressions

• VAR be VALUE - Assign
• yap VALUE|VAR - Print
• VALUE|VAR reckons VALUE|VAR - Compare
• peek VALUE|VAR pls CODE thx - If statement
• peek VALUE|VAR pls CODE nah CODE thx - If statement with an else branch.
• throw VALUE - Push an event to the event queue.

Values

• Yeah - True
• Nope - False or None

Logic

• flip VALUE|VAR - Not
• y VALUE|VAR - And
• either VALUE|VAR - Or
• neither VALUE|VAR - Xor
• VALUE|VAR add VALUE|VAR - Addition
• VALUE|VAR sub VALUE|VAR - Subtraction
• VALUE|VAR mul VALUE|VAR - Multiplication
• VALUE|VAR dib VALUE|VAR - Division
• VALUE|VAR pow VALUE|VAR - Power
• VALUE|VAR smaller VALUE|VAR - Less than
• VALUE|VAR bigger VALUE|VAR - More than

Magic Vars

• e | event - Current event
