trying this: https://perchance.org/preprocessors

so i didn’t get it to work and eventually did the simplest form but gives error.

i started with altering my name just to mess with stuff

$output(text) =>
  text.replaceAll("Allo","~allo~");
  return text;

(all the examples have the ; so maybe it needs em)

is all the preprocessor is.
and the importerizor is just:
$preprocess = {import:allopreprocess}

yet terrible error: TypeError: Cannot read properties of undefined (reading 'getSelf') at Object.get

i pretty much copypasted stuff and changed a few variables so i is the confuze as to how wrong
