Formatting
Control exactly how log records appear using format strings and tokens.
Format Tokens
python
from logly import logger
sink_id = logger.add(
"formatted.log",
format="{time:YYYY-MM-DD HH:mm:ss.SSS} | {level:<8} | {name}:{function}:{line} - {message}",
)
logger.info("Detailed format")
logger.complete()
logger.remove(sink_id)Common tokens: {time}, {level}, {name}, {function}, {line}, {message}, {extra}.
Callable Formatter
python
from logly import logger
def custom_fmt(record):
return f"[{record['time'].timestamp():.3f}] {record['level'].name}: {record['message']}"
sink_id = logger.add("custom.log", format=custom_fmt)
logger.info("Callable formatter active")
logger.complete()
logger.remove(sink_id)Color Markup
python
from logly import logger
sink_id = logger.add("stderr", colorize=True)
logger.info("<green>Success</green> message")
logger.warning("<yellow><bold>Important warning</bold></yellow>")
logger.complete()
logger.remove(sink_id)Color tags
Use <red>, <green>, <blue>, <yellow>, <magenta>, <cyan>, <bold>, <dim>, <italic>.
