Don't use IndentGuard unconditionally in handleMath(), it should only be
used for display (or block) formulae, but not for the inline ones.
This fixes "losing" the correct indent after a paragraph containing any
inline formulae in the generated Python comments.
In addition to translating the comment itself, also document the type of the
object returned. This is consistent with generating not only :param: but also
:type: for the parameters documented using @param.
The most important change is to ensure that the "Overload" headers added by
PyDocConverter code are indented correctly, i.e. using the same indent level
as the comment itself, otherwise Sphinx directives such as :param: were not
parsed correctly.
Also add a vertical separator using reST "|" formatting character to increase
separation between the overloads.
This was done for plain functions/methods but not constructors, which don't
have "kind=function" attribute.
Just don't check for "kind" at all, the presence of "sym:overloaded" should be
good enough to indicate that it's an overloaded something.
Also add a test for overloaded constructors documentation.
It is very useful to be able to click on the parameter types in a function
documentation to go to this parameter description, so always use hyperlink
markup for the parameters of class types, even if not all of them are
necessarily documented -- Sphinx doesn't seem to complain about links to
unknown classes.
For the parameter documentation to be really taken as such, in its entirety,
by Sphinx, it must be indented relative to the :param: tag. Do this by
appending an extra indent after every line of the output and work around the
unnecessary indent of the last line by removing the trailing whitespace.
This required updating the existing tests and removing the expected but not
present any more whitespace from them, but as trailing whitespace in the
documentation is at best insignificant (and at worst harmful) anyhow, this is
not a big price to pay for simpler translator code.
justifyString() was unused and doesn't seem to be useful as there are no
particular constraints on the line length in Python documentation, so just
preserve whatever is used in the original C++ code.
Sphinx doesn't allow sections inside the function documentation and gives tons
of SEVERE warnings for them, so while just emphasizing the "Overload" header
is not ideal, it is better than before because at least the string "Overload"
itself appears in the Sphinx-generated output.
Using C++ types in documentation for Python users is more harmful than
useless, so use Python types whenever possible and allow defining "doctype"
typemap to customize this for the user-defined types.
reST is standard Python markup, so use *...*, ``...`` and so on instead of
_..._, '...' etc.
No other changes even though the mapping of some Doxygen tags to markup used
for them seems suspicions (e.g. \var almost certainly should be the same as
\em).
Use the more or less standard :param:, :type:, :return: and :raises: in the
function/methods descriptions.
Update the output expected from the Python tests accordingly.
Avoid having to pass dummy empty string arguments, just use default value for
the unused last parameter of handleParagraph().
Also get rid of dozens of "" occurrences in the tag map initialization code,
use a helper function instead.
No real changes.
This makes the code more readable and more extensible as more flags are easier
to add in the future than more boolean parameters.
No user-visible changes.
