Basic features
data BlobContent Source
represents a blob's content (i.e., the content of a file at a given reference).
FileContent [ByteString] | Text file's lines |
BinaryContent ByteString | Binary content |
This is a blob description at a given state (revision)
BlobState | |
|
data BlobStateDiff Source
Represents a file state between two revisions A file (a blob) can be present in the first Tree's revision but not in the second one, then it has been deleted. If only in the second Tree's revision, then it has been created. If it is in the both, maybe it has been changed.
:: (BlobStateDiff -> a -> a) | diff helper (State -> accumulator -> accumulator) |
-> a | accumulator |
-> Ref | commit reference (the original state) |
-> Ref | commit reference (the new state) |
-> Git | repository |
-> IO a |
generate a diff list between two revisions with a given diff helper.
Useful to extract any kind of information from two different revisions. For example you can get the number of deleted files:
getdiffwith f 0 head^ head git where f (OnlyOld _) acc = acc+1 f _ acc = acc
Or save the list of new files:
getdiffwith f [] head^ head git where f (OnlyNew bs) acc = (bsFilename bs):acc f _ acc = acc
Default helpers
This is a proposed diff records for a given file. It contains useful information: * the filename (with its path in the root project) * a file diff (with the Data.Algorythm.Patience method) * the file's mode (i.e. the file priviledge) * the file's ref
data HitFileContent Source
data HitFileMode Source
:: Int | Number of line for context |
-> BlobStateDiff | |
-> [HitDiff] | Accumulator |
-> [HitDiff] | Accumulator with a new content |
A default diff helper. It is an example about how you can write your own diff helper or you can use it if you want to get all of differences.
