The format, how information should be displayed. On {} data gets inserted.
*rotate*: ++
typeof: integer ++
Positive value to rotate the text label.
*max-length*: ++
typeof: integer ++

*min-length*: ++
typeof: integer ++
The minimum length in characters the module should take up.
*align*: ++
typeof: float ++
The alignment of the text, where 0 is left-aligned and 1 is right-aligned. If the module is rotated, it will follow the flow of the text.
*on-click*: ++
typeof: string ++
Command to execute when clicked on the module.
*on-click-middle*: ++
typeof: string ++
Command to execute when middle-clicked on the module using mousewheel.
*on-click-right*: ++
typeof: string ++
Command to execute when you right clicked on the module.
*on-update*: ++
typeof: string ++
Command to execute when the module is updated.
*on-scroll-up*: ++
typeof: string ++
