This project is just a compiler course project, implementing a simple toy language named tc, the abbreviation of typed c.
There is also report and presentation slides, while simplified Chinese version only.
tc, as is named after, is a strongly typed programming language.
In tc, programmer can not do type conversion implicitly, but explicitly with a function from standard library. This is a major difference between C and tc, which ensures the type safety of tc.
The core type system of tc is Simply Typed Lambda Calculus, STLC. Due to the decidability of type inference in STLC, we decide to support it in tc. It frees programmers from writing lots of redundant type annotations.
The "c" in "typed c" have two explanation. One is of course C language, the other is the Caml language. In short, tc is the language that hashs C and Caml into the same block. Now that tc is similar to 2 different languages, features of tc can be divided into 2 classes.
- C-like features
- Mutable Variables, Pointers and Array
whileandifControl Flow
- Caml-like features
- Type Inference
- Immutable Variables
- Algebraic Data Types, ADT : compose atom types.
- Functions as First Citizens
Details are discribed in ./spec.
