const FilterBlobless = "blob:none"

FilterBlobless is a filter that excludes blobs from the clone. When using this filter, the initial Git clone will download all reachable commits and trees, and only download the blobs for commits when you do a Git checkout (including the first checkout during the clone).

When using a blobless clone, you can still explore the commits of the repository without downloading additional data. This means that you can perform commands like `git log`, or even `git log -- <path>` with the same performance as a full clone.

Commands like `git diff` or `git blame <path>` require the contents of the paths to compute diffs, so these will trigger blob downloads the first time they are run.

Types

type AddWorkTreeOptions added in v0.9.0 

type AddWorkTreeOptions struct {
	// Orphan specifies whether the working tree should be created from a new,
	// orphaned branch. If true, the Ref field will be ignored.

	// Ref specifies the branch or commit to check out in the working tree. Will
	// be ignored if Orphan is true.
	Ref string
}

type BareCloneOptions added in v0.9.0 

type BareCloneOptions struct {
	// BaseDir is an existing directory within which all other directories created
	// and managed by the BareRepo implementation will be created. If not

	// Overriding that default is useful under certain circumstances.
	BaseDir string
	// InsecureSkipTLSVerify specifies whether certificate verification errors
	// should be ignored when cloning the repository. The setting will be
	// remembered for subsequent interactions with the remote repository.
