canonize :: PrimCanonize prim => prim x y -> FL prim x y Source
It can sometimes be handy to have a canonical representation of a given
patch. We achieve this by defining a canonical form for each patch type,
and a function canonize
which takes a patch and puts it into
canonical form. This routine is used by the diff function to create an
optimal patch (based on an LCS algorithm) from a simple hunk describing the
old and new version of a file.
tryToShrink :: PrimCanonize prim => FL prim x y -> FL prim x y Source
sortCoalesceFL :: PrimCanonize prim => FL prim x y -> FL prim x y Source
sortCoalesceFL
ps
coalesces as many patches in ps
as
possible, sorting the results in some standard order.
canonizeFL :: PrimCanonize prim => FL prim x y -> FL prim x y Source
canonizeFL
ps
puts a sequence of primitive patches into
canonical form. Even if the patches are just hunk patches,
this is not necessarily the same set of results as you would get
if you applied the sequence to a specific tree and recalculated
a diff.
Note that this process does not preserve the commutation behaviour of the patches and is therefore not appropriate for use when working with already recorded patches (unless doing amend-record or the like).
