<｜begin▁of▁sentence｜>### Instruction:
As a fitness instructor, you may need to create and customize messages to motivate and guide your clients during workouts or training sessions. Could you please provide more details about the specific placeholders and terminal control strings to be used in the messages? This will help me assist you in creating a TerminalController instance and formatting the messages effectively for your fitness sessions.
### Response:
import sys

class TerminalController:
    def __init__(self, term_stream=sys.stdout):
        # Initialize with appropriate values for the current terminal
        self.stream = term_stream

    def render(self, template):
        # Replace $-substitutions in the template string
        # This is a simplified example; actual implementation would handle
        # terminal control strings
        return template.replace('$-', '')

# Example usage
controller = TerminalController()
formatted_output = controller.render('Output with $-special formatting$-.')
print(formatted_output)
