[PATCH 5/6] python/aqmp-tui: add syntax highlighting |
Date: |
Sat, 3 Jul 2021 02:56:02 +0530 |
Add syntax highlighting for the incoming and outgoing QMP messages.
This is achieved using the pygments module which was added in a
previous commit.
The current implementation is a really simple one which doesn't
allow for any configuration. In future this has to be improved
to allow for easier theme config using an external config of
some sort.
