Diff

A diff shows the changes between trees, an index or the working dir:

# Diff two trees
>>> t0 = repo.head.tree
>>> t1 = repo.head.parents[0].tree
>>> diff = t1.diff(t0)
>>> diff

# Diff a tree with the index
>>> tree = repo.head.tree
>>> diff = tree.diff(repo.index)

# Diff a tree with the current working dir
>>> tree = repo.head.tree
>>> diff = tree.diff()

The interface for a diff:

Diff.changes          -- Dict of 'files' and 'hunks' for every change
Diff.patch            -- a patch for every changeset
Diff.merge            -- Merge two Diffs
