Skull flags

$ skull main.sk -c -o main.o

Compiles main.sk into an object file called main.o.

$ skull main.sk -S

Output assembler for main.sk.

$ skull main.sk -E
...

Outputs LLVM IR from main.sk to stdout.

Skull header file

C/C++ programs can now include headers for Skull types:

#include <skull/Skull.h>

SkullInt add_one(SkullInt num) {
	return num + 1;
}

New escape sequences

# \0 null terminator
c_str := "hello world\0"

# \e escape shorthand
color := "\e[32;1Bright Green"

Other notable features/bugfixes:

• main implicitly returns 0.
• Variables can be used on the left/right hand side of operations (add, subtract, etc).
• Error when explicitly dividing by zero.
• Error on redundant reassignment of variable (x = x).
• Error on unreachable code after return.
