type Editor struct {
	Args  []string
	Shell bool
}

func NewDefaultEditor

func NewDefaultEditor() Editor

NewDefaultEditor creates a struct Editor that uses the OS environment to locate the editor program, looking at EDITOR environment variable to find the proper command line. If the provided editor has no spaces, or no quotes, it is treated as a bare command to be loaded. Otherwise, the string will be passed to the user's shell for execution.

func (Editor) Launch

func (e Editor) Launch(path string) error

Launch opens the described or returns an error. The TTY will be protected, and SIGQUIT, SIGTERM, and SIGINT will all be trapped.

func (Editor) LaunchTempFile

func (e Editor) LaunchTempFile(prefix, suffix string, r io.Reader) ([]byte, string, error)

LaunchTempFile reads the provided stream into a temporary file in the given directory and file prefix, and then invokes Launch with the path of that file. It will return the contents of the file after launch, any errors that occur, and the path of the temporary file so the caller can clean it up as needed.
