Is it possible to edit the error template in Maya using python?

I'm currently learning how to code in python and I was trying to raise exceptions in my code to make my tool more user-friendly. However, I find the template given by Maya to be too simple and I'd like to have more control over it.

Normally, the base template looks a little like this:

raise Exception(errorTitle)

>>> Result
# Error: errorTitle
# Traceback (most recent call last):
#   File "<maya console>", line 1, in <module>
# Exception: errorTitle #

It works fine, but it doesn't let you give a more detailed description of the error. What I'm trying to achieve would look a little more like this:

raise Exception(errorTitle, errorDescription)

>>> Result
# Error: errorTitle
# errorDescription
# Traceback (most recent call last):
#   File "<maya console>", line 1, in <module>
# Exception: errorTitle #

I also tried putting the errorDescription into errorTitle by adding a new line to the string, but since errorTitle is repeated twice, it becomes confusing quickly when trying to sort errors.

I know you can't really use multiple arguments in the raise function, so I was wondering if there was an error template in Maya I could reference instead of raising an error.

Alternatively, is there a way to create my own error template? If I can reuse the Traceback function and change the script bar color, it might be easier to just do that.

Thanks in advance!

Solution

You can get your desired result just like that:

>>> raise Exception("Error Title\nError description that explains the problem")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
Exception: Error Title
Error description that explains the problem

Or you may want to declare your custom exception class:

class YourException(Exception):
    def __init__(self, title, description):
        super(YourException, self).__init__(title + "\n" + description)

and then you can use your original syntax:

>>> raise YourException("Error Title", "Error description that explains the problem")
  File "<stdin>", line 1, in <module>
__main__.YourException: Error Title
Error description that explains the problem
