- Reference implementation in pure Elixir of the Git object model and storage, including optimized pack-refs and pack-objects/deltas).
- Protocol over Git codec and backend to customize them and reuse the same versioning logic in a completely different environment and use case: JSON into Riak for instance.
TODO:
- test it (only for regression, currently it works on many open source git repo, so it can be considered as tested)
- add a
Gitex.mergehelper to help you construct a commit tree from multiple trees - add impl
Gitex.Repofor Pid as a GenServer RPC - implementation example of previous GenServer maintaining ETS LRU cache of standard git fs objects and deltas
- add some useful alternative implementations, currently only standard object encoding and storage
r = Gitex.Git.open #Gitex.Git is the .git fs object storage
Gitex.get("master",r) #get commit
Gitex.get("myannotatedtag",r) #get tag object
Gitex.get("master",r,"/path/to/dir") #get tree object
Gitex.get("master",r,"/path/to/file") #get blob
# get all commits from master to 1st January 2015
Gitex.history("master",r)
|> Enum.take_while(& &1.committer.utc_time > {{2015,1,1},{0,0,0}})
# get the stream of version history of a given file
Gitex.history("master",r)
|> Stream.map(&Gitex.get_hash(&1,r,"/path/to/file"))
|> Stream.dedup
|> Stream.map(&Gitex.object(&1,r))
# commit history stream is powerful, play with it
Gitex.get("master",r) # return commit
|> Gitex.put(r,"/some/path/file1","file1 content") #put new trees and return new root tree hash
|> Gitex.put(r,"/some/other/path/file2","file2 content") ##put new trees and return new root tree hash
|> Gitex.commit(r,"master","some commit message") #save tree in a commit with "master" parent then update "master" and return commit hash
|> Gitex.tag(r,"mytag") # save this commit to a soft tag return commit_tag
|> Gitex.tag(r,"myannotatedtag","my message") # save this commit to a tag object with comment, return tag hash
# Currently "put" is the only helper to construct a new "tree", for merging you have to construct the tree yourselfA nice function Gitex.align_history allows you to lazily add an index number to your
history stream in order to construct a pretty visualizer very easily (d3.js for instance)
Gitex.history(:head,repo) |> Gitex.align_historyAny repo implementing the Gitex.Repo protocol : (basically object codec, ref
setter/resolver, binary get/put) can be managed with the Gitex API.
