This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# IO.seek (from ruby core) --- seek(offset, whence = IO::SEEK_SET) -> 0 --- Seeks to the position given by integer `offset` (see [Position](#class-IO-label-Position)) and constant `whence`, which is one of: * `:CUR` or `IO::SEEK_CUR`: Repositions the stream to its current position plus the given `offset`: f = File.open('t.txt') f.tell # => 0 f.seek(20, :CUR) # => 0 f.tell # => 20 f.seek(-10, :CUR) # => 0 f.tell # => 10 * `:END` or `IO::SEEK_END`: Repositions the stream to its end plus the given `offset`: f = File.open('t.txt') f.tell # => 0 f.seek(0, :END) # => 0 # Repositions to stream end. f.tell # => 70 f.seek(-20, :END) # => 0 f.tell # => 50 f.seek(-40, :END) # => 0 f.tell # => 30 * `:SET` or `IO:SEEK_SET`: Repositions the stream to the given `offset`: f = File.open('t.txt') f.tell # => 0 f.seek(20, :SET) # => 0 f.tell # => 20 f.seek(40, :SET) # => 0 f.tell # => 40 Related: IO#pos=, IO#tell.
