ANSI color codes are not interpreted in the filter

[goekce]

Thanks for this convenient plugin!

I use:

let g:markdown_runners = {'py' : 'ipython'}

If I run the following py block

I get:

As far as I understand, vim does not interpret the ANSI color sequences like a terminal, but it is possible to open a terminal inside vim using :term. Is it possible to forward the filter output to a terminal window?

Lastly: a workaround in my case is to use:

let g:markdown_runners = {'py' : 'ipython --colors NoColor'}
