We decided to migrate a forum that I moderate from SMF to IPBoard. So far we love it, but the text editor is just horrible. It constantly breaks posts should you 'double preview' or make consecutive edit-previews. Since I author and edit a lot of wall-posts there, I use Sublime Text for a lot of it. I did some searching and found a couple packages specifically for BBCode and IPSBBCode, but neither offered any kind of syntax highlighting or proper tab-triggers.
I am still working on this but most of the difficult RegExp is done. Wouldn't be so bad if BBCode wasn't a variable language Just thought I would share for some feedback. As I said it's not done yet but it's almost ready for the Hub:
