Also new in the upcoming release of RSyntaxTextArea will be PHP highlighting support. This has been the most commonly asked-for language for awhile now, and I’m happy it’s finally getting added.
Unfortunately, due to the sheer number of functions in PHP, this support raises the size of the RSTA jar considerably (we’re close to 500 kb now!). But disk space is cheap these days, and besides, if the library size is an issue to you, you can always simply remove the classes for highlighting languages you don’t need. You can cut out all language highlighters except one, if that’s all you need, and the jar could sit at around 200 kb. And that nets you not only syntax highlighting, but also find/replace, auto-indentation, mark occurrences and more.
