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.

Example

To get the dimensions of your terminal window, simply use the following:

if let Some((w, h)) = term_size::dimensions() {
    println!("Width: {}\nHeight: {}", w, h);
} else {
    println!("Unable to get term size :(")
}

Functions

dimensions	Query the current processes's output, returning its width and height as a number of characters.
dimensions_stderr	This isn't implemented for Windows
dimensions_stdin	This isn't implemented for Windows
dimensions_stdout	Query the current processes's output, returning its width and height as a number of characters. Returns None if the output isn't to a terminal.
