Method: ARGF#to_a

Defined in:
io.c

#readlines(sep = $/, chomp: false) ⇒ Array #readlines(limit, chomp: false) ⇒ Array #readlines(sep, limit, chomp: false) ⇒ Array

ARGF.to_a(sep = $/, chomp: false) -> array

ARGF.to_a(limit, chomp: false)      -> array
ARGF.to_a(sep, limit, chomp: false) -> array

Reads each file in ARGF in its entirety, returning an Array containing lines from the files. Lines are assumed to be separated by sep.

lines = ARGF.readlines
lines[0]                #=> "This is line one\n"

See IO.readlines for a full description of all options.

Overloads:

  • #readlines(sep = $/, chomp: false) ⇒ Array

    Returns:

  • #readlines(limit, chomp: false) ⇒ Array

    Returns:

  • #readlines(sep, limit, chomp: false) ⇒ Array

    Returns:
