I have a master .vimrc that sets up my global working environment, including special setup for both C++ and Python filetypes.
In a project folder I have an .exrc with project-specific settings for C++, but this is overriding my master .vimrc settings for Python.
How can I create an autocommand that sets these options only if it is not a python file? I don't want to wrap the project C++ settings in an autocommand because we have multiple source file types and that means a lot of duplicated code in .vimrc as well as the potential to miss a file type.
What I really want is a construct like this:
if Filetype python then
...
else
...
endif
But it would be sufficient to simply do this:
if not Filetype python then ...
