A picture is better than 1000 words. But, which words? or for programming, which code? Most visual programming efforts focus on representing algorithm logic with diagrams. But I think the difficulty to understand most complex programs (from my own experience) lies in the complexity of data structures, not the code logic. Reasoning about the algorithm is like reading a story, it is kinda intuitive; but for a large data structure (say a big struct with more than 20 fields), it's very hard to keep all those in your memory, you always have to go to its definition to refresh your memory, very frustrating. One of my tricks for reading a large open source project is to first find all the key data structures, draw them and the relationships on paper, then reading the code becomes easier and more pleasant. So maybe if a visual programming UI displays data structures with a visual format always on screen, it can help boost coding productivity. |
