Modules¶

Importing other Keel files¶

You can import other Keel files with the import keyword at the top-level.

Imports can be nested, and circular imports are detected and produce an error.

import "fibonacci_lib.kl"; // all functions/structs are available under fibonacci_lib::
import "other_lib.kl" as mylib; // all functions/structs are available under mylib::

fn main() {print(mylib::my_func(42));}

Importing libraries¶

Keel libraries are ordinary Keel files. The libs/ folder located next to the Keel executable (currently in /Library/Keel/ on macOS and /usr/local/lib/keel/ on Linux) is checked by the import keyword if the file isn't found locally, making global Keel libraries possible. For example, the math, time, random libraries are located in libs/std/. As such, by placing .kl files in the libs/ folder, you can make libraries available globally.

import "std/math.kl";
import "std/time.kl";
import "std/random.kl";

fn main() {
    print(math::cos(3.14159265359));
    print(random::random_range(10.0,20.0));
    print(time::format(time::now(), "%x - %X %p"));
}
