syntax issues while searching text in docs

[Jeremy Laing]

Im trying to replace text that matches [X] or [O] exactly. with the [] included. using the replaceText method and it uses googles regexp syntax. 

from what i can tell is there no way to specify exactly that I only want [ and ]? because everything I see is either \* for all punctuation, or [[:punct:]] for the same result. I cant use these are there are a few cases were data will be -X- which would also be replaced. 

here is the last code i used that worked:

reqs.getParagraphs().forEach(element => body.appendParagraph(element.copy().editAsText().replaceText('[[:punct:]]O[[:punct:]]',notCompletedEmoji).asParagraph().copy().editAsText().replaceText('\[X\]',completedEmoji).asParagraph()));

like i said this works but it also hits -X- or -O- which I cant have it doing.

any tips?

im generally new to regexp but i looked through the reference a million times and tried what i thought would work.

I was able to get the following to work. Because of the funky regex Google uses, you have to escape the backslash.. the backslash that is escaping the brackets:

function myFunction() {

  var body = DocumentApp.getActiveDocument().getBody();

  body.replaceText("(\\[X\\])", "😀");

  body.replaceText("\\[O\\]", "🤣");

}
