About the use of loguru in pyqt5 (hashtag440)

[vikramsubramanian]

Recently, when I was using PyQT5, I thought of using the Loguru section for logging because there were no exceptions in PyQT5. However, I found that there were other problems with using the Loguru , which prevented my original program from performing properly。 I always take 1 positional argument but 2were given when decorating a slot function with slot function takes one argument, self） If possible, I would like to know how to use Loguru to log exceptions in PyQT5. )

To use Loguru for logging exceptions in PyQt5, you can follow these steps:

• Import the logger from Loguru.
• Set up the logger configuration with the desired level, format, and sink (e.g., file, stderr).
• Use the logger.exception() method within an exception handling block to log exceptions.

Here's an example of how you might configure Loguru and use it within a PyQt5 application:

from loguru import logger
from PyQt5.QtWidgets import QApplication, QMainWindow

# Configure the logger
logger.add(sys.stderr, format="{time} {level} {message}", filter="my_module", level="INFO")

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        # Your initialization code here

    def some_method(self):
        try:
            # Your code that might raise an exception
            pass
        except Exception as e:
            logger.exception("An exception occurred")

# Initialize and run the PyQt5 application
app = QApplication([])
window = MainWindow()
window.show()
app.exec_()

In the above example, replace "my_module" with the name of your module or any specific logger filter you want to apply. The logger.exception("An exception occurred") call will automatically capture the exception information and stack trace.

Regarding the error message "I always take 1 positional argument but 2 were given when decorating a slot function with slot function takes one argument, self", it seems unrelated to Loguru. This error typically occurs when a signal is connected to a slot that expects a different number of arguments than the signal sends. Ensure that the signal and slot have compatible arguments. If you need further assistance with this specific error, please provide the relevant PyQt5 code snippet.
