Class Method Details

.description ⇒ Object

# File 'lib/byebug/commands/frame.rb', line 241

def description
  %{f[rame][ frame-number]

    Move the current frame to the specified frame number, or the 0 if no
    frame-number has been given.

    A negative number indicates position from the other end, so "frame -1"
    moves to the oldest frame, and "frame 0" moves to the newest frame.

    Without an argument, the command prints the current stack frame. Since
    the current position is redisplayed, it may trigger a resyncronization
    if there is a front end also watching over things.}
