#initialize(string = String.new, mode = nil) ⇒ StringIO
StringIO.new(string=“”[, mode])
Creates new StringIO instance from with string and mode.

Instance Attribute Details
#lineno ⇒ Object
strio.lineno -> integer
Returns the current line number in strio. The stringio must be opened for reading. lineno
counts the number of times gets
is called, rather than the number of newlines encountered. The two values will differ if gets
is called with a separator other than newline. See also the $.
variable.
strio.lineno = integer -> integer
Manually sets the current line number to the given value. $.
is updated only on the next read.

Class Method Details
.open(*args) ⇒ Object
StringIO.open(string=“”[, mode]) {|strio| …}
Equivalent to StringIO.new except that when it is called with a block, it yields with the new instance and closes it, and returns the result which returned from the block.

#print(*args) ⇒ Object
strio.print() => nil
strio.print(obj, ...) => nil
Writes the given object(s) to <em>strio</em>. The stream must be
opened for writing. If the output record separator (<code>$\\</code>)
is not <code>nil</code>, it will be appended to the output. If no
arguments are given, prints <code>$_</code>. Objects that aren't
strings will be converted by calling their <code>to_s</code> method.
With no argument, prints the contents of the variable <code>$_</code>.
Returns <code>nil</code>.
io.print("This is ", 100, " percent.\n")
<em>produces:</em>
This is 100 percent.

#puts(*args) ⇒ Object
strio.puts(obj, …) -> nil
Writes the given objects to <em>strio</em> as with
<code>IO#print</code>. Writes a record separator (typically a
newline) after any that do not already end with a newline sequence.
If called with an array argument, writes each element on a new line.
If called without arguments, outputs a single record separator.
io.puts("this", "is", "a", "test")
<em>produces:</em>
this

a

#sysread(length = nil, buffer = String.new) ⇒ Object Also known as: readpartial, read_nonblock
strio.sysread(integer[, outbuf]) -> string
Similar to #read, but raises EOFError
at end of string instead of returning nil
, as well as IO#sysread does.

strio.truncate(integer) -> 0
Truncates the buffer string to at most integer bytes. The strio must be opened for writing.

#ungetc(chars) ⇒ Object
strio.ungetc(string) -> nil
Pushes back one character (passed as a parameter) onto strio such that a subsequent buffered read will return it. Pushing back behind the beginning of the buffer string is not possible. Nothing will be done if such an attempt is made. In other case, there is no limitation for multiple pushbacks.

#write(str) ⇒ Object Also known as: syswrite, write_nonblock
strio.write(string) -> integer
strio.syswrite(string) -> integer
Appends the given string to the underlying buffer string of strio. The stream must be opened for writing. If the argument is not a string, it will be converted to a string using to_s
. Returns the number of bytes written. See IO#write.
