Detailed Methods

env.get(key, default_val = null)

Retrieves the value of environment variable key. If the variable is not set, returns default_val (or null if not specified):

var port = env.get("PORT", "8080");
var api_key = env.get("API_SECRET");

if (api_key == null) {
    print("Warning: API_SECRET is not configured!");
}

---

env.set(key, val)

Sets an environment variable for the current process and its spawned children:

env.set("APP_ENV", "production");
print("Mode: " + env.get("APP_ENV"));

---

env.has(key)

Returns true if the environment variable exists, otherwise false:

if (env.has("CI")) {
    print("Running inside Continuous Integration environment.");
}

---

env.all()

Dumps all current environment variables into a RayQuiro object:

var vars = env.all();
print("Home Directory: " + vars["HOME"]);
print("Current Path: " + vars["PATH"]);
