Upstream description
This description is kept separate from distribution package descriptions.
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).
Prooftree can mark the proof command that introduced a certain
existential variable and thus help to locate the problem when Coq says:
No more subgoals but non-instantiated existential variables.
Packages by operating system
Every link opens the native package record, where versions, dependencies, files, checksums, repositories, and maintainers remain distribution-specific.
Mapping provenance
Only source-backed identity signals create public cross-OS links. A reviewer can later approve or dispute an inferred relationship without rewriting native package history.
No field-level source record is published yet.
