Instance Method Summary collapse
-
#getch(min: nil, time: nil, intr: nil) ⇒ String
See IO#getch.
-
#getpass(prompt = nil) ⇒ String
See IO#getpass.
-
#read_nonblock(integer[, outbuf [, opts]]) ⇒ String
Similar to #read, but raises
EOFError
at end of string unless the exception: false option is passed in. -
#readbyte ⇒ Object
Like
getbyte
, but raises an exception if already at end-of-stream; see Byte IO. -
#readchar ⇒ String
Like
getc
, but raises an exception if already at end-of-stream; see Character IO. -
#readline(*args) ⇒ Object
Reads a line as with IO#gets, but raises EOFError if already at end-of-file; see Line IO.
-
#readpartial(*args) ⇒ Object
Similar to #read, but raises
EOFError
at end of string instead of returningnil
, as well as IO#sysread does. -
#sysread(*args) ⇒ Object
Similar to #read, but raises
EOFError
at end of string instead of returningnil
, as well as IO#sysread does.
