canonize :: PrimCanonize prim => prim x y -> FL prim x y

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

sortCoalesceFL :: PrimCanonize prim => FL prim x y -> FL prim x y

sortCoalesceFL ps coalesces as many patches in ps as possible, sorting the results in some standard order.

join :: PrimCanonize prim => (prim :> prim) x y -> Maybe (FL prim x y)

canonizeFL :: PrimCanonize prim => FL prim x y -> FL prim x y

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).
