HCODX is a free online compiler and code runner: write code in your browser, execute it on a cloud sandbox, and interact with your program through a live terminal. Students use it for coursework and interview practice; developers use it to test snippets in 85+ languages without setting up a local environment.
Born from the lolcat meme at its 2007 peak, LOLCODE was specified by Adam Lindsay at Lancaster University as a language whose keywords are internet-cat grammar: programs open with HAI, close with KTHXBYE, and print with VISIBLE. Beneath the jokes sits a workable imperative language with variables via I HAS A, conditionals through O RLY?, loops in IM IN YR blocks, and typed values it calls NOOBs, NUMBRs, and YARNs. It became one of the most recognizable joke languages ever, a staple of esolang lists and novelty golf answers alike. HCODX runs a LOLCODE interpreter in a real interactive terminal, so GIMMEH genuinely waits for the line you type, with nothing to install first.
HAI 1.2
BTW VISIBLE prints a line to the terminal
VISIBLE "HAI, WORLD!"
KTHXBYELOLCODE is a gateway drug for esolang exploration and a reliable laugh in teaching settings: because the semantics underneath are ordinary, students can write real loops and conditionals while the meme syntax keeps the room engaged. It appears in novelty and popularity-contest challenges on Code Golf Stack Exchange, and implementing a LOLCODE interpreter is a popular weekend project since the 1.2 specification is short, complete, and freely available. HCODX is a free online LOLCODE editor, runner and interpreter — an IDE-grade compiler and playground to write and run code online, execute code with live output and live preview, no downloads or web server required.
Yes, within limits. The 1.2 specification defines variables, arithmetic, string concatenation with SMOOSH, conditionals, switch-style WTF? blocks, loops, and functions declared with HOW IZ I. Multiple interpreters implement it faithfully. It is Turing complete and perfectly capable of FizzBuzz or text processing; what it lacks is libraries and any reason beyond joy to use it in production.
The GIMMEH statement reads a line from stdin into a variable as a YARN, LOLCODE's string type, which you can recast to a NUMBR with MAEK or implicit typecasting for arithmetic. In the HCODX terminal GIMMEH blocks until you press enter, so interactive prompt-and-respond programs behave exactly as the specification intends.
They are the mandatory program delimiters in the specification, standing in for the greeting and sign-off of lolspeak conversation. HAI traditionally carries a version number such as 1.2 so interpreters know which specification revision to apply. Omitting either is a syntax error in strict interpreters, which is itself part of the joke: meme grammar, rigidly enforced.
