starry

Starry is a stack-based (esoteric) programming language "like a twinkling starry sky", as described in "The Weird Programming Language in Ruby".

The only characters used are +*.,`' and spaces, the rest are ignored. The number of spaces before a character determines the type of instruction. See also esolangs pages.

Starryとは『Rubyで作る奇妙なプログラミング言語』で説明されている、 「きらめく星空のような」スタックベースのオリジナル言語。 使用する文字は +*.,`' とスペースのみで、他は無視される。 文字の前のスペースの数で命令の種類を決定する。 詳しくは esolangs pages を参照。
