"""Example of using literalizer."""

from literalizer import literalize_yaml
from literalizer.languages import GO

yaml_config = """\
# Server configuration
host: localhost  # default host
port: 8080
# Enable debug mode for development
debug: true
"""
result = literalize_yaml(
    yaml_string=yaml_config,
    language=GO,
    prefix="    ",
    wrap=True,
)
# result:
# map[string]any{
#     // Server configuration
#     "host": "localhost",  // default host
#     "port": 8080,
#     // Enable debug mode for development
#     "debug": true,
# }
