Functions

func Asset 

func Asset(name string) ([]byte, error)

Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetDir 

func AssetDir(name string) ([]string, error)

AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy: 

data/
  foo.txt
  img/
    a.png
    b.png

then AssetDir("data") would return []string{"foo.txt", "img"} AssetDir("data/img") would return []string{"a.png", "b.png"} AssetDir("foo.txt") and AssetDir("notexist") would return an error AssetDir("") will return []string{"data"}.

func AssetInfo 

func AssetInfo(name string) (os.FileInfo, error)

AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetNames 

func AssetNames() []string

AssetNames returns the names of the assets.

func BindFlags 

func BindFlags(flags *pflag.FlagSet) clientcmd.ClientConfig

func GenMarkdown 

func GenMarkdown(cmd *cobra.Command, w io.Writer) error

GenMarkdown creates markdown output.

func GenMarkdownTree 

func GenMarkdownTree(cmd *cobra.Command, dir string) error

GenMarkdownTree will generate a markdown page for this command and all descendants in the directory given. The header may be nil. This function may not work correctly if your command names have `-` in them. If you have `cmd` with two subcmds, `sub` and `sub-third`, and `sub` has a subcommand called `third`, it is undefined which help output will be in the file `cmd-sub-third.1`.
