Tomorrow, I will discuss with the first half of my student project students
(3 students) about what exact topic they will pursue. My idea is to let them
start a Grapefruit-based darcs GUI. They should not use the currenct darcs
interface directly where it doesn’t fit GUI frontends well. Instead they
should write a wrapper around the “ugly” parts which exposes a “nice”
interface. Later, one could merge this wrapper into the darcs codebase so
that darcs exports the “nice” interface then. The GUI code wouldn’t have to
change much then.
In April, the second half of the students will start with their project. If
there is some graphics support in Grapefruit at that time then they might
work on a patch viewer.
What do you think about that?
