    Paragraph Packing

    Page <URL:http://www.merlyn.demo n.co.uk/js-quick.htm> now contains code
    to pack text into multiple paragraphs of given right margin (the nominal
    range is from 1 to nearly Infinity).


    function Pak(F) { var S = F.Code.value, L = +F.Len.value, J, Re
    S = S.replace(/(\r?\n){2,}/g, "\u0000").repla ce(/(\r?\n)/g, " ")
    S = S.replace(/\s+/g, " ").split("\u000 0")
    if (L<1) L = F.Len.value = 1
    Re = new RegExp("(.{1," + L + "}) ", "g")
    J = S.length ; while (J--)
    S[J] = (S[J].replace(/^\s+/, "")+" ").replace( Re, "$1\n")
    F.Code.value = S.join("\n") }


    F.Code is the I/O textarea; Code.L gives the margin.

    The input paragraph separator is an empty line or lines.

    It works in my IE4 ; any comment, particularly in respect of recognising
    line-ends in non-Windows systems ?

    Also - is anything wrong with using \u0000 as a marker?


    The feature can be used to normalise badly-posted plain text, for more
    comfortable reading.

      Seems to work fine in Safari 1.0.3, it does not recognise new lines in
      IE 5.2 (Mac). I'll mess around with and see if I can find the
      appropriate character - maybe \u0000 is the issue.

          Could be; for test purposes one can use the uncontentious but rare #
          instead; literally or as \u0023 (?).

          But I'd look closely at the two (\r?\n) ... It may be necessary to do
          them in two stages each, first for \r\n and second for \r|\n.


          Thanks for looking.
