MY E KEY BROKE

This is still a work in progress. It may be changed in the future.

MY E KEY BROKE is an esolang by user:raiseafloppafan7741 in 2026 after realizing the E key on his keyboard completely stopped working. This language is meant to cause pain to those without a functioning E key, or a broken Shift key.

Overview

There are two stacks. Each instruction is followed by a number of es which corresponds to the next state number, starting from 1.

Ee pushes a 0 to the current stack.

EEe increments the top of the current stack.

EEEe decrements the top of the current stack and moves to the state right after it. However if it is zero, then it jumps to the next state specified by the es instead.

EEEEe swaps the top two values of the current stack.

EEEEEe reads a byte of input and pushes it to the current stack. -1 is pushed on EOF.

EEEEEEe pops the top of the current stack and prints it.

EEEEEEEe duplicates the top of the current stack.

EEEEEEEEe discards the top of the current stack.

EEEEEEEEEe halts. Unlike the others, it does not have es after it as there is no next state.

EEEEEEEEEEe switches the current working stack.

EEEEEEEEEEEe moves the top element of the other stack to the current working stack.

Any errors will halt parsing and print out MY E KEY BROKE.

Examples

Error quine

This works because M is not a valid command.
