Three years has past from this discussion but still I think that the pyx*
commands and functions are useful. So I have updated Marc's patch for Vim 8.0.
Changes from the original patch are:
* Update for the latest code base.
* Update documents.
* Fix coding style.
* Add has('pythonx').
* Rename the 'pythonx' option to 'pythonxversion'.
* Make Python 3 as the default when build with both Python 2 and 3.
Ubuntu 16.04 and some other distributions already make Python 3 as the
default. It's good time to set Python 3 as the default.
* Support shebangs with :pyxfile.
* Respects the 'modelines' option when checking pythonx special comments with
* Remove the 'loadpyplugins' option.
There was no consensus about this option.
* Add checking when setting the 'pythonxversion' option.
Accept only 2 and 3.
Please check this:
(Tests are not available yet.)
This would be most useful when used with pythonx-directory.
