Importing Modules

An important aspect of every programming language is importing code created before either by you or by someone else. We call these modules in Ryna and you can import code selectively from them. Let's take a look at how.

Syntax

The syntax we need to use to import modules is as follows:

//Import function/s from a module
import fn function_name from module_name;
import fn {function_name1, function_name2, ...} from module_name;
import fn * from module_name;

//Import class/es from a module
import class class_name from module_name;
import class {class_name1, class_name2, ...} from module_name;
import class * from module_name;

//Import interface from a module
import interface interface_name from module_name;
import interface {interface_name1, interface_name2, ...} from module_name;
import interface * from module_name;

//Import syntax (macro) from a module
import syntax syntax_name from module_name;
import syntax {syntax_name1, syntax_name2, ...} from module_name;
import syntax * from module_name;

//Import operators from a module
import prefix op "op" from module_name;
import prefix op {"op1", "op2", ...} from module_name;
import prefix op * from module_name;

import postfix op "op" from module_name;
import postfix op {"op1", "op2", ...} from module_name;
import postfix op * from module_name;

import binary op "op" from module_name;
import binary op {"op1", "op2", ...} from module_name;
import binary op * from module_name;

import nary op "op" from module_name; // Concatenate open and close symbols for these
import nary op {"op1", "op2", ...} from module_name;
import nary op * from module_name;

// Import everything from a module
import * from module_name;

As you can expect, you have to configure the module_name module in your ryna_config.yml before importing it.

Local imports

Local imports are a special case that apply when you want to import code from a file that is not main.ryna and is located inside the project folder (with any number of anidated folders). For this, just use the syntax /folder/of/the/file, where the file is <project_folder>/folder/of/file.ryna. It is important the the path starts with /.
