Constructor Details

#initialize(*args) ⇒ Object

Create a new logger.

By default, it logs to stderr.

You can provide your proper backend. You have to make sure that it exposes a printf, puts, or write (lookup is done in that specific order). StringIO is a perfect candidate.

You can also provide a format (String) if your backend supports a printf.

Examples:

backend = StringIO.new
parser.logger = TreeSitter::Logger.new(backend)

Parameters:

  • args (Array) —

    The first argument is always a backend. The second argument is the format.
