func EditLoop

func EditLoop(ctx context.Context, fname, initial string, parse func(updated string) error) error

EditLoop launches OS-specific editor (VI, notepad.exe or another editor configured through environment variables) It creates a temporary file with 'initial' contents and repeatedly invokes the editor until the provided 'parse' function returns nil result indicating success. The 'parse' function is passed the contents of edited files without # line comments.
