I am looking at this google prettify project: https://github.com/google/code-prettify
In the usage section it says to use it like so:
<pre class="prettyprint">class Voila {
public:
// Voila
static const string VOILA = "Voila";
// will not interfere with embedded <a href="#voila2">tags</a>.
}</pre>
I am looking for a way to style all pre tags without having to add a class to the pre tag. Is there some way to do this with this library or another similar library? I am trying to syntax highlighting in the browser for Java/JavaScript etc.
This is a somewhat hacky solution, but looking at the (minified) code in that library, prettyprint
is used in the following section:
u = /\bprettyprint\b/
and
if ((k !== h || u.test(n)) && !e.test(n)) {
q = !1;
for (l = d.parentNode; l; l = l.parentNode)
if (w.test(l.tagName) && l.className &&
u.test(l.className)) {
It tests whether the className
of the iterated elements matches that regular expression. So, if you just remove those tests against u
, it should work without having to add a class to the <pre>
s:
if (!e.test(n)) {
q = !1;
for (l = d.parentNode; l; l = l.parentNode)
if (w.test(l.tagName)) {
It's now only testing if w
( /^(?:pre|code|xmp)$/i
) matches the tagName
of the element.
