Modules

Importing Modules

Use the use keyword to import a dryLang module:

use "helpers"

This loads helpers.y from the same directory.

Path Resolution

The .y extension is added automatically.

Exporting

By default, all top-level variables and functions in a module are exported (accessible to importers).

Use pv to mark items as private:

// math.y

// Exported — accessible by importers
fn add(a, b) { rev a + b }
fn sub(a, b) { rev a - b }
PI 3.14

// Private — NOT accessible by importers
pv fn internal_calc(x) { rev x * x }
pv secret "abc123"

Multi-File Programs

Running Multiple Files

You can run multiple files together:

y file1.y,file2.y

Or run all .y files in a directory:

y myfolder
y all

Files are concatenated in order, so declarations in earlier files are available in later files.

Importing via URL

You can import scripts directly from the internet by providing a full URL:

use "https://example.com/math.y"

pt add(2, 3)

The compiler fetches the file, parses its AST, and prepends its statements into your program.

GitHub Shorthand

dryLang natively supports importing scripts directly from GitHub repositories:

use "github.com/user/repo"

The compiler automatically translates this to: https://raw.githubusercontent.com/user/repo/main/idx.y

It looks for idx.y as the default entry point of the remote module.

You can also specify a path within the repo:

use "github.com/user/repo/lib/utils.y"

If two modules import the same file, dryLang only loads it once. The resolved path is cached globally across the entire compilation.
