Inserting code into blog entries

[Misha]

This probably isn't so much a bug as it could be a desired feature. But nevertheless I think it's worth pointing out.

I decided to go about and add a Java code snippet to my blog entry. I thought the way I'd achieve it is would be to surround it with a pre tags indicating preformatted text, but this didn't achieve the required result.

This is what I entered into the blog:

Code: Select all

<pre>
    // Remove duplicates from a list in-place
    private static <T extends Comparable<? super T>> 
        void removeDuplicates(List<T> list) {            
        Collections.sort(list);
        int i = 0;
        // once reached second last element, break
        while (i < list.size() - 1) {
            T t1 = list.get(i);
            T t2 = list.get(i+1);
            if (t1.compareTo(t2)) {
                list.remove(i+1);                
            } else {
                ++i;
            }
        }
    }
</pre>

NL2BR inserted br tags after each newline in my code block, and part of the code was garbled as it looks like HTML to a parser.

Is there an easy way to post code in S9Y blog entries? Something like the wayyou can insert code into posts on this forum. I'm a developer, so it's really handy for me to able to do that. I'm sure other people would have come across this problem, but I haven't seen this mentioned in the FAQ or on the forum. If I've missed it, my apologies.

Thanks in advance!

Hi!

The easiest way of inserting code is to use a plugin like GeShi or BBCode with the

Code: Select all

 tag.

However, the nl2br plugin will always interfer, so will need to disable that plugin. You can also conditionally disable this plugin for specific entries by using the entryproperties plugin.

nl2br is pretty dumb, so it will never know whether it shall or shall not translate specific newlines. Sadly finding an algorithm where nl2br shall be done and where not requires a huge regular expression overhead, and many rules that are a pain to figure out ; so in most cases, nl2br is not suitable for advanced users...

The "Wiki" plugin f.e. offers both nl2br transformation and <code> blocks, but is hard to use in some other instances - maybe this one helps you along?

Best regards,
Garvin

Hello,

Thank you for your quick reply. I installed the BBCode plugin and it's working great.

Thanks again!

As the author of the GeSHi plugin, I thought I'd point out that it does color syntax highlighting for a bunch of different languages, including Java. It can also provide line numbering, while still allowing someone to cut the code without the line numbers. Give it a try if any of these features appeals to you.
