Is there for Vim what Gource is for Git, to visualize Vim undo history?
I'm familiar with Gundo, which display diffs of undo history, but it's not really a visualizer like Gource for Git repos.
EDIT: this is only an alternative, not a relevant answer.
You're looking for vim undotree.
It shows the full history tree, and diffs with the current version.
Convert the undo history into a Git repo using Rich's UndoCommits
function, then use something like gitk
to visualize that Git repo's diffs.
Gource would only be useful if each commit UnoCommits
produces were timestamped with the date/time of the undo; I'm not sure how to get that info, but it must be in the Gundo source code somewhere.
