README

go-ac

ac is helper library that creates CREDITS files(s) using go version -m and gocredits.

Requirement

• Go 1.13
• gocredits: if you want to use gocredits as extarnal program.

Functions

func DistSuffix

func DistSuffix(d string) []string

DistSuffix returns suffix of d(ie. linux_386 -> [linux 386], linux_amd64_v1 -> [linux amd64_v1])

func ReplaceItem

func ReplaceItem(r [][]string, s string) string

ReplaceItem replaces s by r.

func ResetDir

func ResetDir(name string, perm os.FileMode) error

ResetDir calls RemoveAll (if name is exists) and Mkdir.

Types

type Dist

type Dist interface {
	Run() error
}

Dist provide functions to write some CREDITS files for each binary files (ie. foo_linux_386, foo_darwin_amd64 -> CREDITS_linxu_386, CREDITS_darwin_amd64)

Dist は各バイナリファイルから、それぞれ用の CREDITS ファイルを書き出す機能を提供する.

type DistBuilder

type DistBuilder interface {
	WorkDir(string) DistBuilder
	DistDir(string) DistBuilder
	OutDir(string) DistBuilder
	BaseName(string) DistBuilder
	ReplaceOs([][]string) DistBuilder
	ReplaceArch([][]string) DistBuilder
	Uniq(bool) DistBuilder

	OutputBuilder(OutputBuilder) DistBuilder

	OutStream(io.Writer) DistBuilder
	ErrStream(io.Writer) DistBuilder

	Branch() DistBuilder
	Build() Dist
}

DistBuilder builds Dist.

func NewDistBuilder

func NewDistBuilder() DistBuilder

NewDistBuilder returns the instance of DistBuilder.

type FuncOutputBuilder

type FuncOutputBuilder interface {
	// contains filtered or unexported methods
}

FuncOutputBuilder adds properties to Output(Builder).

type Output

type Output interface {
	Flush() (hash []byte, err error)
}

Output provides functions to write the CREADITS file from the binary file.

Output はバイナリファイルから CREADTIS ファイルを書き出す機能を提供する.

type OutputBuilder

type OutputBuilder interface {
	GoSumFile(string) OutputBuilder
	WorkDir(string) OutputBuilder
	Binary(string) OutputBuilder
	OutStream(io.Writer) OutputBuilder
	ErrStream(io.Writer) OutputBuilder

	ProgOutput
	FuncOutputBuilder

	Branch() OutputBuilder
	Build() Output
}

OutputBuilder builds CreaditsFile.

今回はそれほどコスト気にする必要はないので、各メソッドで深いコピー(ぽいこと)を行う.

func NewOutputBuilder

func NewOutputBuilder() OutputBuilder

NewOutputBuilder returns the instance of OutputBuilder.

type ProgOutput

type ProgOutput interface {
	Prog(string) OutputBuilder
}

ProgOutput adds properties to Output(Builder).
