Esoteric IDE

Esoteric IDE is an interpreter and debugger for some esoteric programming languages (or esolangs).

Allows you to run code in any supported esolang
Allows you to set breakpoints
Allows you to debug through code step by step
Displays the execution state (program state) at every step (kinda like a watch window)
In some esolangs, displays information about the instruction the cursor is on

In chronological order of implementation in Esoteric IDE:

Sclipting — Similar to GolfScript but using Chinese characters.
Ziim — 2D language using only arrows (← ↑ → ↓ etc.).
Brainfuck — The classic. Supports many different flavours, e.g. cells can be byte-size or arbitrary-size; output can be as numbers or as Unicode characters.
Quipu — Inspired by the ancient Inca’s quipu system of recording information as knots in a thread, thus also known as talking knots.
Unreadable — Consists only of apostrophe (') and double-quote (") characters.
Mornington Crescent — Travel on the London Underground, but remember to always come back to Mornington Crescent.
Hexagony — Program instructions and memory locations are laid out in a 2D hexagonal grid.
Labyrinth — Two-dimensional stack-based language where the code can self-modify by applying cycling rotations of rows or columns of characters.
Stack Cats — Reversible programming language in which every program must be a mirror image of itself.
Whitespace — Only space, tab and newline are significant.
Runic — Two-dimensional stack-based language with multiple instruction pointers, limited memory per pointer, and unicode modifier symbols.
Ndim — Multidimensional language inspired by Befunge in which values you want to keep in memory must be written into the code space.

You have several options:

Clone and compile.
Download the full source from the Releases page. This contains the source for Esoteric IDE, but not the git repo.
If you just want compiled binaries of the newest commit (as opposed to the newest release), you can download those from the artifacts page on AppVeyor.
