|
|
Prooftree is a program for proof-tree visualization during interactive
|
|
proof development in a theorem prover. It is currently being developed
|
|
for Coq and Proof General. Prooftree helps against getting lost between
|
|
different subgoals in interactive proof development. It clearly shows
|
|
where the current subgoal comes from and thus helps in developing the
|
|
right plan for solving it.
|
|
|
|
Prooftree uses different colors for the already proven subgoals, the
|
|
current branch in the proof and the still open subgoals. Sequent texts
|
|
are not displayed in the proof tree itself, but they are shown as a
|
|
tool-tip when the mouse rests over a sequent symbol. Long proof commands
|
|
are abbreviated in the tree display, but show up in full length as
|
|
tool-tip. Both, sequents and proof commands, can be shown in the display
|
|
below the tree (on single click) or in a separate window (on double or
|
|
shift-click).
