Import/Export

Import

To import another script, use the import statement:

import "std";

print("hello"); | print is defined in `std`

When importing, buzz will search the script in common places. With ? being the library name:

When defining extern functions, buzz will search the symbol in a dynamic library. It'll be searched in the same common places:

You can scope the imported symbol behind a prefix to avoid name collision or for readability.

import "std" as std;
import "io" as io;

| Defining our own print function
fun print(str message) > void {
    io.stdout.write(message);
}

To export symbols, use the export statement:

| hello.buzz
fun sayHello() > void {
    print("Hello world!");
}

| Make it visible when imported
export sayHello;

| main.buzz
import "hello";

fun main([str] args) > void {
    sayHello();
}

You can also put export right before the declaration:

export fun sayHello() > void {
    print("Hello world!");
};

You can export a declaration with another name.

| hello.buzz
fun sayHello() > void {
    print("Hello world!");
}

export sayHello as hello;

| main.buzz
import "hello";

fun main([str] args) > void {
    hello();
}
