In plain words

Blank is a stack-based esoteric programming language created by Andrew Turley in 1997. Programs use single-character instructions within braces and numbers within brackets, with numbers pushed onto a stack during execution. The language was influenced by Befunge-93 but operates in one dimension rather than two. Blank is designed for programming enthusiasts interested in experimental and unconventional language design.

We are currently working on new rules for what content should and shouldn't be allowed on this website, and are looking for feedback! See Esolang:2026 topicality proposal to view and give feedback on the current draft. Blank is a stack -based esoteric programming language developed by Andrew Turley in 1997. Blank programs use single-character instructions contained within braces and numbers contained within brackets. Each number is an 'instruction' in the sense that 'executing' a number means to push it onto the stack. Blank was heavily influenced by Befunge -93, except that it is one-dimensional; thus it is sometimes informally referred to as Unefunge -93. A program in Blank is a sequence…from esolangs.org

    Hi friends, I started casually working on scrapscript in 2015. I built a few compilers over the years to test out various ideas/implementations, and I think I'm finally happy with the overall design. The code is not public yet. Email me at [email protected] if you're interested in joining the core team later this year. Let me know if you have any questions or feedback :)

    i made an esoteric programming language which i call spellscript. every program is a "spell" written in a "grimoire," and you have to use keywords like summon, enchant, inscribe, and conjure. it's literally read like a spellbook because the syntax consists of all natural language, and newlines are optional. your code can now be an essay, like everybody wants! for example, if you want to print something, you'd write: `begin the grimoire. inscribe whispers of "hello, world!". close the grimoire.` it has variables, dynamic typing, arrays, functions, conditionals, loops, string manipulation,…

    I made this simple language over the past year, and it's time for me to say it's "done" (for now) and focus on other projects. I've struggled to answer the question "what is this language for?" other than "it's just for me" — and that's probably good enough. But I also wanted to make something "complete" that others could use if they wanted to. Writing my own language was an incredibly rewarding experience, and I'd recommend everyone trying it. Let me know if you have any questions or feedback, and please share your own experience if you've also made a language.
