Exception Handling
Logly provides catch() as both a decorator and context manager.
Context Manager
python
from logly import logger
with logger.catch():
result = 1 / 0
logger.info("Execution continues")
logger.complete()Decorator
python
from logly import logger
@logger.catch()
def process():
raise ValueError("Invalid input")
process()
logger.complete()Custom Level and Message
python
from logly import logger
with logger.catch(level="CRITICAL"):
database.connect()
logger.complete()Re-raise After Logging
python
from logly import logger
with logger.catch(reraise=True):
risky_operation()
logger.complete()Don't swallow exceptions silently
Use reraise=True in production when you want to log the error but still propagate it.
Exclude Specific Exceptions
python
from logly import logger
with logger.catch(exclude=ValueError):
raise TypeError("This will propagate")
logger.complete()INFO
The onerror callback lets you run custom logic when an exception is caught.
