Class Method Details

.width ⇒ Number

Attempts to determine the width of the terminal. This is currently only supported on POSIX systems, and relies on the claims of `stty` (or `tput`).

Inspired by code from Thor; thanks wycats!

Returns:

  • (Number) —

    The column width of the terminal. Defaults to 80 columns.
