Package gitobj reads and writes loose and packed Git objects.
To access a repository's objects, begin by "opening" that repository for use:
package main
import (
"github.com/git-lfs/gitobj"
)
func main() {
repo, err := gitobj.FromFilesystem("/path/to/repo.git", "")
if err != nil {
panic(err)
}
defer repo.Close()
}You can then open objects for inspection with the Blob(),
Commit(), Tag(), or Tree() functions:
func main() {
repo, err := gitobj.FromFilesystem("/path/to/repo.git", "")
if err != nil {
panic(err)
}
defer repo.Close()
commit, err := repo.Commit([]byte{...})
if err != nil {
panic(err)
}
}Once an object is opened or an instance is held, it can be saved to the object
database using the WriteBlob(), WriteCommit(),
WriteTag(), or WriteTree() functions:
func main() {
repo, err := gitobj.FromFilesystem("/path/to/repo.git", "")
if err != nil {
panic(err)
}
defer repo.Close()
commit, err := repo.Commit([]byte{...})
if err != nil {
panic(err)
}
commit.Message = "Hello from gitobj!"
commit.ExtraHeaders = append(commit.ExtraHeaders, &gitobj.ExtraHeader{
K: "Signed-off-by",
V: "Jane Doe <[email protected]>",
})
if _, err := repository.WriteCommit(commit); err != nil {
panic(err)
}
}Package gitobj has support for reading "packed" objects (i.e., objects found
in packfiles) via package github.com/git-lfs/gitobj/pack. Package pack
implements searching pack index (.idx) files and locating the corresponding
delta-base chain in the appropriate pack file. It understands both version
1 and version 2 of the packfile specification.
gitobj will always try to locate a loose object first. If a loose object
cannot be found with the appropriate SHA-1, the repository's packfile(s) will
be searched. If an object is located in a packfile, that object will be
reconstructed along its delta-base chain and then returned transparently.
