Method: ARGF#each_byte

Defined in:
io.c

#bytes {|byte| ... } ⇒ Object #bytes ⇒ Object

ARGF.each_byte {|byte| block } -> ARGF

ARGF.each_byte                  -> an_enumerator

Iterates over each byte of each file in ARGV. A byte is returned as a Fixnum in the range 0..255.

This method allows you to treat the files supplied on the command line as a single file consisting of the concatenation of each named file. After the last byte of the first file has been returned, the first byte of the second file is returned. The ARGF.filename method can be used to determine the filename of the current byte.

If no block is given, an enumerator is returned instead.

For example:

ARGF.bytes.to_a  #=> [35, 32, ... 95, 10]

Overloads:

  • #bytes {|byte| ... } ⇒ Object

    Yields:

    • (byte)
