Okay, you have a good point about the links making the text
un-selectable. What do you think about the version below where we use
JavaScript to install a click handler? I can mark text anywhere and when
doing so the URL is updated to include the relevant ID, so that one can
copy-paste the URL.
<html>
<head>
<style>
pre > span {
display: inline-block;
width: 100%;
white-space: pre-wrap;
counter-increment: lineno;
}
pre > span:before {
display: inline-block;
width: 2em;
margin-right: 1em;
font-size: small;
font-style: italic;
text-align: right;
content: counter(lineno);
}
pre > span:nth-child(even) {
background-color: lightgrey;
}
pre > span:target {
background-color: yellow;
}
</style>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("pre").on("click", "span", function (e) {
window.location = "#" + this.id;
});
});
</script>
</head>
<body>
<p>Text before</p>
<pre>
<span id="l1"> Leading tab: x</span>
<span id="l2"> Leading whitespace!</span>
<span id="l3">Trailing whitespace! </span>
<span id="l4">More trailing whitespace... </span>
<span id="l5">Embedded tab.</span>
<span id="l6">Very, very, long, very, long, very, long, very, long, very, long, long line...</span>
<span id="l7">Trailing whitespace! </span>
<span id="l8">More trailing whitespace... </span>
</pre>
<p>Text after</p>
</body>
</html>
