![]() ![]() Basically, the compiler will also check that each instruction is correct from the point of view of the types. I discussed static and dynamic typing in vast detail in a previous article. Yes, there’s something “implicit” after all. The main reason for this is because types are inferred by the compiler. Although things are explicit, you don’t need to type a lot on the keyboard. I believe this encourages the developer to think more about what she writes. There are almost no “implicit” instructions or assignments. Given the nature of what Semantic Analysis has to do, is very important to understand the key concepts of the Language. Grammar and Language reviewīefore going further, I think it’s worth taking a minute and review the peculiarities of the Grammar I designed, and of the Language I am building. In this one, we are going to see the implementation I made of these concepts, specific for the language I designed. There are several pillars that all Semantic Analysis implementations are based on, and I discussed them in a previous article. The beautifully complex thing about Semantic Analysis is that most of the things it does depends on the given language specification. As said before, I didn’t use any of such tools, because I think it’s worth doing it “by hand” once in a lifetime, for the sake of learning. This is why there exist tools, such as ANTLR, that implement them almost automatically. HOW TO CREATE SEMANTIC RULES EXAMPLES CODEIn Lexical Analysis (as well as in Parsing), some large part of the code can be realized with standard algorithms. ![]()
