warn(msg)

Input: msg · Output: no output

What it is

Takes one argument, msg (a string), and prints warning: {msg} to the console. Non-fatal — execution continues on the next line, unlike error.

Overloads

One call shape — this function is not overloaded.

Examples

From the documentation, and run by the build -- the output and the figure below are what the engine actually produced. Simplest first.

echo("temperature =", 23.5, "C")
warn("input clipped to [0, 1]")
print("done")
