As a programmer and linux geek I often need, or at least want to write about code, scripts and commands on my blog, but as many of you know, displaying raw code in HTML is setting yourself up for failure. The simplest part of the problem is the fact that line breaks and whitespace might be significant, this is simply solved by putting the code inside a
block. The more tricky part is that code often is full of characters like &, > and <. Characters that have a specific meaning in HTML and can’t be echoed directly. & needs to be typed as an HTML entity (&), just as > (>) and < (<). Talking about HTML and XML code on your blog can be a really tedious task (as the above).
I have usually solved this by writing the code in a file first, and then running the file through this sed commandcat file.html|sed -e 's/&/&/' -e 's/</</' -e 's/>/>/'
But as I work on a Macintosh these days, I’ve been using TextMate a bit.. Not as much as i use OpenKomodo though. TextMate has some nice blogging capabilities. You can use it to post directly onto your blog, and it has shortcuts for converting sections of your post into HTML entities. Just select the text, and hit ⌘+&, 1
Edit: it seems like there is some compatibility problems with WordPress 2.7 and TextMate. The post was published two hours off, and as a private post.
