Packages, imports, and exports

Silk has explicit module/package structure:

• a source file may declare package ...; or header-form module ...; (mutually exclusive),
• imports come next as a contiguous block,
• then declarations (fn, let, struct, enum, impl, ...).

Silk supports both:

• package imports (import std::io;, import ui;),
• file imports (import { Name } from "./module.slk";).

Full reference: packages imports exports.

Notes#

• Full rules and many examples: packages imports exports

Syntax#

package my_app;

import std::io;
import { add } from "./math.slk";
import helpers from "./helpers.slk"; // default import / namespace import

export fn main () -> int { return 0; }

Examples#

Example: named file import#

// math.slk
package app;

export fn add (x: int, y: int) -> int {
  return x + y;
}

// main.slk
package app;

import { add } from "./math.slk";

fn main () -> int {
  return add(40, 2);
}

Example: default export and default import#

// module.slk
package module;

export default fn () -> int {
  return 1 + 2;
}

// main.slk
import foo from "./module.slk";

fn main () -> int {
  return foo();
}
