^title Stdin Class
The standard input stream.
## Static Methods
### **isRaw**
Returns `true` if stdin is in raw mode. When in raw mode, input is not echoed
or buffered, and all characters, even non-printing and control characters go
into stdin.
Defaults to `false`.
### **isRaw**=(value)
Sets raw mode on or off.
### **isTerminal**
Returns `true` if Stdin is connected to a "TTY". This is true when the user is
running Wren in an interactive terminal, and false if it its input is coming
from a pipe.
### **readByte**()
Reads one byte of input from stdin. Blocks the current fiber until a byte has
been received.
Returns the byte value as a number or `null` if stdin is closed.
Note that output is not automatically flushed when calling this. If you want to
display a prompt before reading input, you'll want to call `Stdout.flush()`
after printing the prompt.
### **readLine**()
Reads one line of input from stdin. Blocks the current fiber until a full line
of input has been received.
Returns the string of input or `null` if stdin is closed.
Note that output is not automatically flushed when calling this. If you want to
display a prompt before reading input, you'll want to call `Stdout.flush()`
after printing the prompt.
