Modules

Ez has a very minimal module system.

It is similar to c, except no preprocessor or .h files.

Functions are the only thing that can be exported from .ez files to other files.

Here is an example:

lib.ez

Export function MulByTwo(n),
  return n * n.
!

main.ez

External function MulByTwo(n).

set twelve to MulByTwo(6).

To compile this into a single binary, run:

# this produces a lib.ez.o file
$ ezc lib.ez -lib
# this produces a main.ez.o file
$ ezc main.ez -nolink
# this links everything together
$ ld main.ez.o lib.ez.o -o out

For another example of this, with a Makefile, go here: https://github.com/g-w1/ezc/tree/master/tests/module.

Ez uses the systemv x86_64 so you can also import and export functions to c or any language that can use this abi in the exact same way.
