## TTY
|
||
|
|
|
||
|
|
Use `require('tty')` to access this module.
|
||
|
|
|
||
|
|
|
||
|
|
### tty.open(path, args=[])
|
||
|
|
|
||
|
|
Spawns a new process with the executable pointed to by `path` as the session
|
||
|
|
leader to a new pseudo terminal.
|
||
|
|
|
||
|
|
Returns an array `[slaveFD, childProcess]`. `slaveFD` is the file descriptor
|
||
|
|
of the slave end of the pseudo terminal. `childProcess` is a child process
|
||
|
|
object.
|
||
|
|
|
||
|
|
|
||
|
|
### tty.isatty(fd)
|
||
|
|
|
||
|
|
Returns `true` or `false` depending on if the `fd` is associated with a
|
||
|
|
terminal.
|
||
|
|
|
||
|
|
|
||
|
|
### tty.setRawMode(mode)
|
||
|
|
|
||
|
|
`mode` should be `true` or `false`. This sets the properies of the current
|
||
|
|
process's stdin fd to act either as a raw device or default.
|
||
|
|
|
||
|
|
|
||
|
|
### tty.getColumns()
|
||
|
|
|
||
|
|
Returns the number of columns associated with the current process's TTY.
|
||
|
|
|
||
|
|
Note that each time this number is changed the process receives a `SIGWINCH`
|
||
|
|
signal. So you can keep a cache of it like this:
|
||
|
|
|
||
|
|
var columns = tty.getColumns();
|
||
|
|
process.on('SIGWINCH', function() {
|
||
|
|
columns = tty.getColumns();
|
||
|
|
});
|
