FUNCTIONS

rhombus

Draws a rhombus with letters and returns it as a string.

If no option value is supplied or if it is invalid, then a default will be silently assumed (omitting all options will return a rhombus of 25 lines).

Given that the specified number of lines is even, it will be incremented to satisfy the requirement of being an odd number.

Options:

• lines

  Number of lines to be printed. Defaults to 25.

• letter

  Letter to start with. Defaults to a.

• case

  Lower/upper case of the letters within the rhombus. Defaults to upper.

• fillup

  The fillup character. Defaults to +.

EXPORT

Functions

rhombus() is exportable.
