    This function returns an array of the indentation level of each line of a string.
I made this as part of a yaml parser I'm trying to do =D
you use it like this:
getIndent("\t\t\ttext\n\tmore text\nnot indented")
and it returns this:
[3,1,0]

  

  

## annotated.js
function(a,b){
for(a in b=a.split("\n"))          //for each line
b[a]=/\t*/.exec(b[a])[0].length;   //replace string with indentation level
return b                           //return the array
}

## index.js
function(a,b){for(a in b=a.split("\n"))b[a]=/\t*/.exec(b[a])[0].length;return b}
//@maettig's version
function(a,b){b=[];a.replace(/^\t*/gm,function(c){b.push(c.length)});return b}

foo.innerHTML = getIndent("\t\t\ttext\n\tmore text\nnot indented")
