In control engineering or instrumentation, I see Simulink or LabVIEW(G) is pretty popular. In ESL design, I see that Agilent SystemVue is gaining some popularity.
If you see the well established compiler theroy, almost 100% is about the textual language. But how about the graphical language?
Is there any noticable research or discussion about the graphical programming language? In terms of
- Theory about Graphical Language - syntactic/semantic analysis and whatever relevant
- expressiveness (Actually, I asked a question about it at SO - What do you mean by the expressiveness of a programming language?)
- Possibility of the Graphical language
- ...
Or what do you think about the Graphical Programming Language?
