Overview
Raised by some ::IO operations when reaching the end of file. Many IO methods exist in two forms,
one that returns nil
when the end of file is reached, the other raises EOFError
.
EOFError
is a subclass of ::IOError.
file = File.open("/etc/hosts")
file.read
file.gets #=> nil
file.readline #=> EOFError: end of file reached
