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.
