Crate term_size

System calls for getting the terminal size.

Getting the terminal size is performed using an ioctl command that takes the file handle to the terminal – which in this case, is stdout – and populates a structure containing the values.

The size is needed when the user wants the output formatted into columns: the default grid view, or the hybrid grid-details view.

Functions

dimensions

Query the current processes’s output (stdout), input (stdin), and error (stderr) in that order, in the attempt to dtermine terminal width. If one of those streams is actually a tty, this function returns its width and height as a number of characters.

dimensions_stderr

Query the current processes’s error output (stderr) only, in the attempt to dtermine terminal width. If that streams is actually a tty, this function returns its width and height as a number of characters.

dimensions_stdin

Query the current processes’s input (stdin) only, in the attempt to dtermine terminal width. If that streams is actually a tty, this function returns its width and height as a number of characters.

dimensions_stdout

Query the current processes’s output (stdout) only, in the attempt to dtermine terminal width. If that streams is actually a tty, this function returns its width and height as a number of characters.
