Types

type Command

type Command struct {
	// Path to the local package directory
	Path string

	// Ref is the target Ref in the upstream source package to compare against
	Ref string

	// DiffType specifies the type of changes to show
	DiffType DiffType

	// Difftool refers to diffing commandline tool for showing changes.
	DiffTool string

	// DiffToolOpts refers to the commandline options to for the diffing tool.
	DiffToolOpts string

	// When Debug is true, command will run with verbose logging and will not
	// cleanup the staged packages to assist with debugging.
	Debug bool

	// Output is an io.Writer where command will write the output of the
	// command.
	Output io.Writer

	// PkgDiffer specifies package differ
	PkgDiffer PkgDiffer

	// PkgGetter specifies packaging sourcing adapter
	PkgGetter PkgGetter
}

Command shows changes in local package relative to upstream source pkg, changes in upstream source package between original and target version etc.

func (*Command) DefaultValues

func (c *Command) DefaultValues()

DefaultValues sets up the default values for the command.

func (*Command) Run

func (c *Command) Run() error

func (*Command) Validate

func (c *Command) Validate() error

type DiffType

type DiffType string

DiffType represents type of comparison to be performed.

const (
	// DiffTypeLocal shows the changes in local pkg relative to upstream source pkg at original version
	DiffTypeLocal DiffType = "local"
	// DiffTypeRemote shows changes in the upstream source pkg between original and target version
	DiffTypeRemote DiffType = "remote"
	// DiffTypeCombined shows changes in local pkg relative to upstream source pkg at target version
	DiffTypeCombined DiffType = "combined"
	// 3way shows changes in local and remote changes side-by-side
	DiffType3Way DiffType = "3way"
)

func (DiffType) String

func (dt DiffType) String() string

String implements Stringer.

type PkgDiffer

type PkgDiffer interface {
	Diff(pkgs ...string) error
}

PkgDiffer knows how to compare given packages.

type PkgGetter

type PkgGetter interface {
	GetPkg(repo, path, ref string) (dir string, err error)
}

PkgGetter knows how to fetch a package given a git repo, path and ref.
