Standard Library

The Rugo stdlib (use modules) is the idiomatic way to work in Rugo. It provides a curated, Ruby-inspired API covering common tasks — math, file paths, encoding, crypto, time, and more.

use "math"
use "filepath"
use "base64"

puts math.sqrt(144.0)                          # 12
puts filepath.join("home", "user", "docs")     # home/user/docs
puts base64.encode("Hello, Rugo!")             # SGVsbG8sIFJ1Z28h

Prefer use modules for standard operations. They are designed for Rugo and follow its conventions. The import keyword (Go bridge) is available for advanced use cases when you need direct access to Go's standard library, but use modules are the recommended, idiomatic approach.

See the full list of available modules in the Modules reference.
