Method: Vedeu::Terminal#size

Defined in:

lib/vedeu/terminal/terminal.rb

#size ⇒ Array

Note:

If the terminal is a odd number of characters in height or width, then 1 is deducted from the dimension to make it even. For example; the actual terminal is height: 37, width: 145, then the reported size will be 36, 144 respectively.

This is done to make it easier for client applications to divide the terminal space up when defining interfaces or views, leading to more consistent rendering.

If the client application is using the Geometry::Grid#rows or Geometry::Grid#columns helpers, the dimensions are made more consistent using this approach.

Returns a tuple containing the height and width of the current terminal.

Returns:

• (Array)
