I am using tig to view git history but the interface is not showing the lines any longer, see picture.
I'm sadly on a Windows environment running git bash. Does anyone know how I can get the lines instead?
You want to change the "graphics" configuration to something your system supports.
Hit ~
until you see something you like; You'll see something in the statusbar that looks like set line-graphics = utf-8
.
Then edit your $HOME/.gitconfig
and add a that line-graphics value to a tig section:
[tig]
line-graphics = utf-8
