Coffee

C-like programming language with Clojures

I don't have the time to do it right the first time, but surely i have the time to do it twice.

-- Example of hello world:
-- re-use external functions delcared in libc
import "std/io" as io

-- this is a comment
int main() {

    for i := 0; i < 3; i = i + 1 {
        io.printf("Hello from coffee!\n")
    }

    return 0
}

Getting started

Dependencies:

• llvm (requires llc executable to be in "$PATH")
• gcc

$ bash install.sh
$ coffee samples/hello.bn
File hello compiled successfully!
$ ./out
Hello from coffee!
Hello from coffee!
Hello from coffee!

Documentation

Waiting for a better way to host it, here you could find the documentation for this language.

If you find something hard to understand, please let me know or open an issue on github. I would really appreciate it.

Scope of this project:

I've pretty high standards, and i'm still too new on the field to know if all of these are doable, but there they are:

• self hosted language

• clojure support

• not nullable values by default (you have to provide ? at the end of a type name if you want to allow null) (to prevent undefined errors)

• simple golike syntax (to prevent headakes)

• repl (for faster feedback loop)

• no floating types, only integers and decimals (to prevent floating point rounding errors)

• easy to test

• c-like features (only the good parts):

  • no truthy & falsy values.
  • null has it's own type
  • no macros
  • something to prevent buffer overflow errors & memory allocation problems
  • easier function pointer syntax

• rich ast library apis for easier to write linting tools, lsps, etc...
