How to Refer to the Size of the Output Window in Julia

Code

The size of the terminal where Julia is running can be obtained via the displaysize function ¹.

displaysize(stdout)

Example

hline() = println("─" ^ displaysize(stdout)[2])

For example, if you define a function hline that prints a horizontal line as above and run it while resizing the window, you can see that the function prints the horizontal line to exactly match the terminal’s width.
