MacWorld has a decent review of BBEdit 8.5, but it fails to mention a new feature that is of particular use to programmers.
One of the features of CodeWarrior that I'd missed was the syntax highlighting that the IDE applied to symbols that were defined within the project. In fact, I hadn't realized just how much I'd come to rely on that feature when writing new code until I started working with BBEdit and XCode. I had a sudden, new-found paranoia about whether or not I'd typed in a symbol name correctly.
Well, if you use ctags in association with BBEdit, BBEdit will apply syntax highlighting to any symbol that's in the tags file that it would use for the "Find Definition" command on the Search menu.
