Synopsis

Documentation

data PatchSet rt p wStart wY where

The patches in a repository are stored in chunks broken up at "clean" tags. A tag is clean if the only patches before it in the current repository ordering are ones that the tag depends on (either directly or indirectly). Each chunk is stored in a separate inventory file on disk.

A PatchSet represents a repo's history as the list of patches since the last clean tag, and then a list of patch lists each delimited by clean tags.

Constructors

PatchSet :: RL (Tagged rt p) wStart wX -> RL (PatchInfoAnd rt p) wX wY -> PatchSet rt p wStart wY 

Instances

Show2 p => Show2 (PatchSet rt p) 
Show2 p => Show1 (PatchSet rt p wStart) 
Show2 p => Show (PatchSet rt p wStart wY) 

data Tagged rt p wX wZ where

A Tagged is a single chunk of a PatchSet. It has a PatchInfo representing a clean tag, the hash of the previous inventory (if it exists), and the list of patches since that previous inventory.

Constructors

Tagged :: PatchInfoAnd rt p wY wZ -> Maybe String -> RL (PatchInfoAnd rt p) wX wY -> Tagged rt p wX wZ 

Instances

Show2 p => Show2 (Tagged rt p) 
Show2 p => Show1 (Tagged rt p wX) 
Show2 p => Show (Tagged rt p wX wZ) 

type SealedPatchSet rt p wStart = Sealed (PatchSet rt p wStart)

data Origin

Origin is a type used to represent the initial context of a repo.

progressPatchSet :: String -> PatchSet rt p wStart wX -> PatchSet rt p wStart wX

Runs a progress action for each tag and patch in a given PatchSet, using the passed progress message. Does not alter the PatchSet.

tags :: PatchSet rt p wStart wX -> [PatchInfo]

tags returns the PatchInfos corresponding to the tags of a given PatchSet.

emptyPatchSet :: PatchSet rt p wX wX

appendPSFL :: PatchSet rt p wStart wX -> FL (PatchInfoAnd rt p) wX wY -> PatchSet rt p wStart wY

appendPSFL takes a PatchSet and a FL of patches that follow the PatchSet, and concatenates the patches into the PatchSet.

newset2RL :: PatchSet rt p wStart wX -> RL (PatchInfoAnd rt p) wStart wX

newset2RL takes a PatchSet and returns an equivalent, linear RL of patches.

newset2FL :: PatchSet rt p wStart wX -> FL (PatchInfoAnd rt p) wStart wX

newset2FL takes a PatchSet and returns an equivalent, linear FL of patches.

patchSetfMap :: (forall wW wZ. PatchInfoAnd rt p wW wZ -> IO a) -> PatchSet rt p wW' wZ' -> IO [a]
