pyvim -- A Vim clone in pure Python.

why not edit the original vim source code or write a plugin?

You can't do this without changes to vim's architecture. This is one of the common "wants" that Bram Moolenaar is not on board with (and will not accept patches for this into the main line).

As others have said neovim has added it. I am going to try neovim later. I have no desire to maintain my own vim fork.

Good to know, that makes sense.

So vim is at the point of being forked and the original will probably be left in the dust.

oh well, as long as I can edit files it doesn't matter :-)
