In Transit

some bug report pages that I visit while on work nag me to madness with their inclusion of non-word-wrapped text within ‘pre’ tag.

Here is an example:

`Mine is a long and a sad tale!' said the Mouse, turning to Alice, and sighing. `It is a long tail, certainly,' said Alice, looking down with wonder at the Mouse's tail' `but why do you call it sad? And she kept on puzzling about it while the Mouse was speaking, so that her idea of the tale was something like this:

greasemonkey is perfect to take care of such irritating behavior. Armed with a decent javascript reference, an excellent greasemonkey tutorial, and plagiarized code from http://jsfromhell.com/string/wordwrap, I wrote my first piece of javascript code – which is also my first greasemonkey script.

Here it is:

// ==UserScript==
// @name          Pre Remove
// @description   Remove all Pre tags
// ==/UserScript==

//copied from http://jsfromhell.com/string/wordwrap
//m is the line number to wrap at, b is the line wrap char
//to insert, I don't know what c is.
String.prototype.wordWrap = function(m, b, c){
      var i, j, s, r = this.split("\n");
      if(m > 0) for(i in r){
              for(s = r[i], r[i] = ""; s.length > m;
                      j = c ? m : (j = s.substr(0, m).match(/\S*$/)).input.length - j[0].length
                      || j.input.length + (j = s.substr(m).match(/^\S*/)).input.length + j[0].length,
                      r[i] += s.substr(0, j) + ((s = s.substr(j)).length ? b : "")
              );
              r[i] += s;
      }
      return r.join("\n");
};

var allPre, thisPre;
allPre = document.getElementsByTagName('pre');
for (var i = 0; i < allPre.length; i++) {
  thisPre = allPre[i];
  preChildren = thisPre.childNodes;
  for (var j = 0; j < preChildren.length; j++) {
      preChildren[i].nodeValue = preChildren[i].nodeValue.wordWrap(72, "\n", false);
  }
}
