Funlang

'Fun', also known as funlang is a fun functional language. Although this is a uni project, there's so much stuff in it that's not part of the spec to make this a proper compiler. Write some programs in it :)!

Some Notes About This Repository

I can't fork the original, because I don't have access to the organisation's settings. I can't even clone after the due date... As a result, I had to recommit everything.

Types

Funlang only has primitive types. These are

Callable(P1, P2, P3, ...) -> R A type that evaluates to R, given a number of parameters. Not a function pointer.
Int A 32-bit signed integer e.g. 0, -15 or 100_000 or even 'a' or 'あ'. Characters are stored as unicode codepoints.
Double A 64-bit floating point number e.g. 0.0, -15. or 10_000.5
String A utf8 static string e.g. "Hello, world!" or "こんにちは世界！".
Bool A boolean true or false
Void Nothing type ...

Link with C

Fun cannot be linked with C at the moment. Everything uses fastcc to allow for tail calls to work. Maybe in the future...

Builtins

Funlang has several intrinsic functions, which have keyword identifiers.

write(String): Void Print a utf8 string's contents
write(Int, true): Void Print an integer as a character
write(Int, false): Void Print an integer
write(Double): Void Print a double
There is no write(Bool), you can simply define it yourself

write will always flush to stdout.

Rather than having a builtin do-nothing function skip, we use ... -- the Void literal for expressions that evaluate to nothing

Example Code

Fun has utf8 strings!
