Hi,

I don't know if it as been done before but I have made a couple of 
bookmarking tools for my personal use:

- A javascript for html books that enable bookmarking of paragraph. It 
adds a bookmark link at the top of the page. Bookmarking is done by 
doublecliking a paragraph. The script use a cookie to remember the 
bookmarked paragraph. Currently only works in Mozilla/Firebird.

- A Perl script for txt books. It convert the txt book into html and 
then works the same way as the javascript solution. This one can 
bookmark either lines or paragraphs and works with Internet Explorer also.

Since I have made them for my personal use they are not polished but 
work great for me. If anyone is interested in them I will post the code 
and will be happy to work on them more.

This is the javascript version. Doubleclick on a paragraph to bookmark. 
After that reload the page and click the bookmark link to return to that 
paragraph. The bookmark is stored in a cookie so the script only works 
if cookie are not disabled. The script only works with HTML books that 
contains paragraph (as far as i know all of the HTML books do). 
Currently only works with Mozilla-powered browsers.

Add the following script just before the end of the body section (</body>):

<script>
init();

function init()
{
    var bookmark = getCookie('bookmark');
    if (bookmark == null)
    {
        bookmark = 0;
    }
    
    var p = document.getElementsByTagName('p');
    var b = document.getElementsByTagName('body');
    
    var a = document.createElement('a');
    a.href = '#bookmark';
    a.innerHTML = 'bookmark';
    b[0].insertBefore(a, p[0]);
    
    for (var i = 0; i < p.length; i++)
    {
        if (i == bookmark)
        {
            a = document.createElement('a');
            a.name = 'bookmark';
            a.innerHTML = '<hr />';
            b[0].insertBefore(a, p[i]);
            p[i].style.backgroundColor = 'lavender';
        }
        p[i].ondblclick = highlight;
        p[i].id = i;
    }
}

function highlight(e)
{
    var p = document.getElementsByTagName('p');
    for (var i = 0; i < p.length; i++)
    {
        p[i].style.backgroundColor = 'white';
    }
    
    var targ;
    if (!e) var e = window.event;
    if (e.target) targ = e.target;
    else if (e.srcElement) targ = e.srcElement;
    if (targ.nodeType == 3) // defeat Safari bug
        targ = targ.parentNode;

    targ.style.backgroundColor = 'lavender';
    
    setCookie('bookmark', targ.id, 365);
}
        
function getCookie(NameOfCookie)
{
    if (document.cookie.length > 0)
    {
        var begin = document.cookie.indexOf(NameOfCookie+"=");
        if (begin != -1) // Note: != means "is not equal to"
        {
            begin += NameOfCookie.length+1;
            var end = document.cookie.indexOf(";", begin);
            if (end == -1) end = document.cookie.length;
                return unescape(document.cookie.substring(begin, end));
        }
    }
    return null;
}

function setCookie(NameOfCookie, value, expiredays)
{
    var ExpireDate = new Date ();
    ExpireDate.setTime(ExpireDate.getTime() + (expiredays * 24 * 3600 * 
1000));

    document.cookie = NameOfCookie + "=" + escape(value) + ((expiredays 
== null) ? "" : "; expires=" + ExpireDate.toGMTString());
}
</script>

Subject: [gutvol-p] Bookmark (bookmarklet)
Message-ID: <41E1FE5D.6090405@sympatico.ca>

This is a bookmarklet version of the javascript tool. The main advantage 
is that you don't have to alter the HTML file in order to use a bookmark.

Once installed, use the bookmarlet to return to a bookmarked paragraph.

Since my script is a bit long it cannot be installed as a regular 
bookmarklet. So, to install:

1- create a new bookmark (this can be done by bookmarking any html page)
2- go to Bookmarks -> Manage bookmarks...
3- right-click on your new bookmark -> Properties
4- change the name (optional)
5- replace the location with the following:

javascript:(function(){function init(){var 
bookmark=getCookie('bookmark');if(bookmark==null){bookmark=0;}var 
p=document.getElementsByTagName('p');var 
b=document.getElementsByTagName('body');var 
mark=document.getElementById('mark');if(mark!=null){b[0].removeChild(mark);}mark=document.createElement('a');mark.name='bookmark';mark.id='mark';mark.innerHTML='<hr 
/>';b[0].insertBefore(mark,p[bookmark]);p[bookmark].style.backgroundColor='lavender';for(var 
i=0;i<p.length;i++){p[i].ondblclick=highlight;p[i].id=i;}document.location='#bookmark';}function 
highlight(e){var p=document.getElementsByTagName('p');for(var 
i=0;i<p.length;i++){p[i].style.backgroundColor='white';}var 
targ;if(!e)e=window.event;if(e.target)targ=e.target;else 
if(e.srcElement)targ=e.srcElement;if(targ.nodeType==3)targ=targ.parentNode;targ.style.backgroundColor='lavender';setCookie('bookmark',targ.id,365);}function 
getCookie(NameOfCookie){if(document.cookie.length>0){var 
begin=document.cookie.indexOf(NameOfCookie+'=');if(begin!=-1){begin+=NameOfCookie.length+1;var 
end=document.cookie.indexOf(';',begin);if(end==-1)end=document.cookie.length;return 
unescape(document.cookie.substring(begin,end));}}return null;}function 
setCookie(NameOfCookie,value,expiredays){var ExpireDate=new 
Date();ExpireDate.setTime(ExpireDate.getTime()+(expiredays*24*3600*1000));document.cookie=NameOfCookie+%22=%22+escape(value)+((expiredays==null)?'':'; 
expires='+ExpireDate.toGMTString());}init();})();

This Perl script transforms a txt into html and ads the javscript for 
bookmarking lines. The script takes one argument as parameter, the name 
of the txt file (ex.: 8946-8.txt) and outputs a html file (ex.: 
8946-8.html). This is not a program and so requires a Perl interpretor 
to be installed.

$file = $ARGV[0];
open(IN, $file);
@lines = <IN>;
close(IN);

$ARGV[0] =~ /(.*)\.(.*)/;
$file = $1 . '.html';
open(OUT, ">$file");

print OUT '<html><head>';
print OUT "<script>function 
getCookie(NameOfCookie){if(document.cookie.length>0){var 
begin=document.cookie.indexOf(NameOfCookie+'=');if(begin!=-1){begin+=NameOfCookie.length+1;var

unescape(document.cookie.substring(begin,end));}}return null;}function

print OUT '</head><body onload="init();">';
print OUT '<div><a id="bookmark" href="#0">bookmark</a></div><p>';

    }
    else

This is an easier to install version of the bookmarklet:

http://jove.prohosting.com/~l3ert/

Just drag and drop the link named bookmarklet onto the bookmark bar of 
your browser or right-click the link and choose bookmark this link.
