Importing

In Radon, currently you can only import radon, mcfunction and python files. Importing radon files will be implemented.

Importing radon files

When radon files are imported, their content will be transpiled from the line that file was imported from.

Example:

// my_file.rn

print("Hello!")

// main.rn

print("Importing it!")

import "my_file.rn"

print("The Hello message should be on top of this!")

This will be executed like so:

print("Importing it!")
print("Hello!")
print("The Hello message should be on top of this!")

Importing mcfunction files

The imports are relative to the file that it's being imported from. For example if you import my_func.mcfunction from main.rn you can use my_func in your code.

Here's a simple example:

import "my_func.mcfunction" as my_func

returned_value = my_func()

Importing python files

Before importing a python file, you need to make a python file. So first check out the Python API page. After creating your python file which might look like this:

import math

from radon.cpl.int import CplInt, CplFloat
from radon.error import raise_syntax_error


def my_func(ctx, args, token):
    if len(args) < 1:
        raise_syntax_error("Expected 1 argument for my_func()", token)
    return args[0]


my_variable = CplInt(None, 10)

pi = CplFloat(None, math.pi)

You can use the import keyword to import everything from the file:

import "my_python_file.py" // Imports everything

a = my_func(50, 100, 200) // The function we defined gives the first value which is 50

b = my_variable // 10

c = pi // 3.141

You can also import the file as an object:

import "my_python_file.py" as my_python_file

a = my_python_file.my_func(50, 100, 200) // The function we defined gives the first value which is 50

b = my_python_file.my_variable // 10

c = my_python_file.pi // 3.141
