Is there a good analysis of why visual programming languages still haven’t taken off? We’re still coding these days ‘linearly’ in a 80×25 text window; while the concepts we represent (data structures, algorithms) seem like they can be more intuitively represented visually.
Two approaches to programming that aren’t just simple text come to mind:
I think Structured Editing is pretty interesting, because it takes the ‘braces with idententation’ convention, which has proven really useful for keeping code organized, to its logical extreme. I think it could really be something, if someone were to make a brilliant (from a usability perspective) implementation of it.
The LabView approach, on the other hand, doesn’t excite me so much. The visual idioms don’t seem powerful and obvious enough, compared to text. I haven’t used LabView much though, so it’s probably better than I think.
