# CPP lang [](https://github.com/monadplus/CPP-lang/actions) ## Project **CPP lang** is a static type-checked general purpose programming language and my very first programming language. The language is similar to C but missing lots of important features such as: - Arrays and pointers - Structs and unions - Syscalls and bindings with lib.c - Native execution on x86 architectures The grammar of the language can be found at [CPP.cf](CPP.cf). ### Structure - The frontend (lexer/parser) is defined at [Lexer.x](src/CPP/Lexer.x) and [Parser.y](src/CPP/Parser.y). - The type checker is defined at [TypeChecker.hs](src/CPP/TypeChecker.hs). - The interpreter is defined at [Interpreter.hs](src/CPP/Interpreter.hs). - The backend for the JVM is defined at [JVM/CodeGenerator.hs](src/CPP/JVM/CodeGen.hs). ## Compile The compiler is written in *Haskell*. You can build the compiler using both [Cabal](https://cabal.readthedocs.io/en/3.4/): ```bash $ cabal build ``` or [Stack](https://docs.haskellstack.org/en/stable/README/): ```bash $ stack build ``` ## Run the interpreter Have a look at the files from [examples](examples/). All of them can be executed on the interpreter. ```bash $ cabal run CPP -- .cc --interpreter ``` ## Run on the JVM First, generate the `*.jar`: ```bash $ cabal run CPP -- .cc --jvm ``` Then, run the `*.jar`: ```bash $ java -jar .jar ``` ## TODO - [ ] Arrays - [ ] Pointers - [ ] Add `char` as primitive type - [ ] =Value= should depend on =TExp= - [ ] The JVM backend is not properly tested
