How to document an exception using Sphinx?

Question

I can't seem to figure out how to document exceptions using Sphinx.

I've tried the following:

def some_funct():
    """
    :raises: ExceptionType: Some multi-line
        exception description.
    """


def some_funct():
    """
    :raises: ExceptionType, Some multi-line
        exception description.
    """


def some_funct():
    """
    :raises ExceptionType: Some multi-line
        exception description.
    """


def some_funct():
    """
    :raises:
        ExceptionType: Some multi-line
            exception description.
    """

Sphinx keeps saying:

"Field list ends without a blank line; unexpected unindent."

So how do I get rid of the message and what is the proper way to document possibly multiple exceptions with multiple-line documentation?

Answer 1

You can use a backslash for line continuation:

def some_funct():
    """
    :raises ExceptionType: Some multi-line \
        exception description.
    """

Update:

Indenting seems to work instead of escaping the newline:

def some_funct():
    """
    :raises ExceptionType: Some multi-line
        exception description.
    """

Answer 2

def some_funct():
    """
    My documentation, but watch the empty line below (necessary)

        :raise: Exception

            when status != my_status 
            | status <= max_status

Note: https://pythonhosted.org/an_example_pypi_project/sphinx.html#full-code-example has some nice samples (not on the multi-line exception unfortunately)

Answer 3

this give me somthing nice.

you forget the : Before the exception name

def some_funct():
    """
    :raise: 
        :IOException: a probleme occured
                      and it can't be passed
    """

Answer 4

I think there's a sample that wouldn't make Sphinx complain:

def some_funct():
    """
    :raises: ExceptionType: Some multi-line
        exception description.

    """

(note the blank line at the end)
