Import from Directory

To import a module that lives inside a Directory:

import Dir.Hello exposing [hello]

You can also do:

import Dir.Hello as Hello

Or:

import Dir.Hello

Note that in this last case you will need to use Dir.Hello in your code, for example: Dir.Hello.hello "World!".

Code

Dir/Hello.roc:

# Only what's listed here is accessible to other modules
module [hello]

hello : Str -> Str
hello = |name|
    "Hello ${name} from inside Dir!"

main.roc:

app [main!] { cli: platform "https://github.com/roc-lang/basic-cli/releases/download/0.19.0/Hj-J_zxz7V9YurCSTFcFdu6cQJie4guzsPMUi5kBYUk.tar.br" }

import cli.Stdout
import Dir.Hello exposing [hello]

main! = |_args|
    # here we're calling the `hello` function from the Hello module
    Stdout.line!(hello("World"))

Output

Run this from the directory that has main.roc in it:

$ roc main.roc
Hello World from inside Dir!
