replacetext() and striptext()

replacetext and striptext

PHP Code:

function replacetext(text, oldtext, newtext) {
  temp.oldlen   = oldtext.length();
  temp.textdiff = newtext.length() - temp.oldlen;
  
  for (temp.p: text.positions(oldtext)) {
    temp.pos = temp.p + temp.textdiff * (temp.index ++);
    text = text.substring(0, temp.pos) @ newtext @ text.substring(temp.pos + temp.oldlen);
  }
  
  return text;
}

function striptext(text, oldtext) {
  return replacetext(text, oldtext, "");
}

I've needed something like this many times, and I've built my own.

This will save me a lot of time, thanks so much!

rep++ sometime within the next 24 hours, unless I've given too much rep to you. We shall see.

You could also create a GuiMLTextCtrl, set the text variable to the string with the \n's then just pull out getlines() which will return the lines as an array.

Another option is to savestring() to a temp file, then loadlines(). Both of these are kind of unnecessary though but should be mentioned regardless.

EDIT:
I don't get why you didn't just do like:

PHP Code:

function replacetext(text) {
  return(text.tokenize("\n"));
}

Well simply tokenizing it caused quite a few problems.

Recently needed replacetext again and didn't like what I had in here. So I updated my original post with a couple of changes. The function runs a little faster than the others on the code gallery at the moment too.
