I spent 4-6 hours the other day trying to figure out the equivalent of Hello World for a MediaWiki parser function extension.

In theory, they have a quick start guide, but that documentation has so many errors, and I spent ages jumping between PHP and a JSON configuration file I barely understood.

At least it's working now. Now time to figure out how the heck to properly interact with the MediaWiki database!

(Perhaps once I'm a bit more confident in MediaWiki development, I'll see if I can tidy up some that documentation.)

Brainfuck would like to have a word

@devilish666 C++ (non-stupid):

#include <stdio.h>
int main() {
puts("Hello, world!");
}
