Themebuilder Configuration Functions Syntax

Theme configuration syntax reference.

Reference

Configuration functions

Portions of the theme configuration may be derivations of other values in the config. Rather than calculating these values manually, several configuration functions are available under the util package. The util package provides convenience functions that can pre-calculate values in the theme during theme construction, rather than affecting any runtime performance.

util.darkenGradient(gradientDetails, scale)

Darkens a given gradient data structure by the scale amount

Parameters

gradientDetails - The gradient data structure in the form of:

  gradientDetails {
    stops = [
      "#ff0000 0%",
      "#ffffff 100%"
    ]
  }

scale - A double representing the percentage to darken. For example: 0.2 will make the color 20% darker

Example

  activeGradientDetails {
    stops = [
      "#1e5799 0%",
      "#2989d8 50%",
      "#207cca 51%",
      "#7db9e8 100%"
      ]
  }
  inactiveGradientDetails = util.darkenGradient(activeGradientDetails, 0.2)

The above example will evaluate to the following:

  activeGradientDetails {
    stops = [
      "#1e5799 0%",
      "#2989d8 50%",
      "#207cca 51%",
      "#7db9e8 100%"
      ]
  }
  inactiveGradientDetails {
    stops = [
      "#18457a 0%",

      "#1963a1 51%",
      "#6494b9 100%"
      ]
  }

util.margin(top [, right [, bottom [, left]]]])

Helper function to assign all margin details in one line. All parameters beyond the first are optional, following CSS style for margin values. All values are in pixels.

Parameters

top - Margin in pixels to apply to the top of the element/widget right - Margin in pixels to apply to the right of the element/widget. If skipped, the top value is used. bottom - Margin in pixels to apply to the bottom of the element/widget. If skipped, the top value is used. left - Margin in pixels to apply to the left of the element/widget. If skipped, the right value is used.

Examples

Normal usage to simply express an otherwise longer set of values
buttonMargin = util.margin(0, 3, 0, 2)

The above example will evaluate to the following: buttonMargin { top = 0 right = 3 bottom = 0 left = 2 }

Skipping values to repeat the existing values
info {
  //...
  margin = util.margin(2, 0)
  //...
}

The above example would evaluate to info { //... margin { top = 2 right = 0 bottom = 2 left = 0 } //... }

util.padding(top [, right [, bottom [, left]]]])

Helper function to assign all padding details in one line. All parameters beyond the first are optional, following CSS style for padding values. All values are in pixels.

Parameters

top - Padding in pixels to apply to the top of the element/widget right - Padding in pixels to apply to the right of the element/widget. If omitted, the top value is used. bottom - Padding in pixels to apply to the bottom of the element/widget. If omitted, the top value is used. left - Padding in pixels to apply to the left of the element/widget. If omitted, the right value is used.

Examples

Same usage as util.margin

util.border(style, [, color [,top [, right [, bottom [, left]]]]]])

Helper function to assign all border details in one line. All paramters beyond the first are optional, though for visible borders, at least the first three should be specified. Note that not all borders are managed using this border object, as in some cases it is need to require that different details are individually described and managed. Border thickness values are integers, treated as pixels.

Parameters

style - The style of the border to use, using the legal values for border-style such as none, solid, dashed, etc color - The css color of the border to use. Defaults to #000000 top - The thickness of the top border. Defaults to 0 right - The thickness of the right border. If omitted, the top value will be used. bottom - The thickness of the bottom border. If omitted, the top value will be used. left - The thickness of the left border. If omitted, the right value will be used.

Examples

No border: border = util.border('none')

Solid blue border on all sides: border = util.border('solid', '#0000ff', 1) This would evaluate to border { style = 'solid' color = '#0000ff' top = 1 right = 1 bottom = 1 left = 1 }

util.abs(value)

Returns the absolute value of the given number

util.min(a, b)

Returns the smaller of the two numbers passed in

util.max(a, b)

Returns the larger of the two numbers passed in

util.extend(originalObject, additionalProperties)

Creates a new object, with all of the values of the first parameter, and overwrites any properties specified in the second parameter.

Parameters

originalObject - The object to clone and then modify. This is typically a reference to an existing object already declared in the config additionalProperties - Properties that should be overwritten in the newly created object

Example

dayText = util.fontStyle('helvetica,arial,verdana,sans-serif', '13px', '#000000')
dayDisabledText = util.extend(dayText, {
  color = '#808080'
})

This would evaluate to: dayText { family = 'helvetica,arial,verdana,sans-serif' size = '13px' color = '#000000' weight = 'normal' } dayDisabledText { family = 'helvetica,arial,verdana,sans-serif' size = '13px' color = '#808080' weight = 'normal' }

util.fontStyle(family [, size [, color [, weight]]])

Helper function to declare text styling in a single line. Only the first parameter is required. Unlike most other sizes that the themer takes, font sizes are treated as a string to support the wide range of possible CSS font-size values.

Parameters

family - The font family to use. Any valid CSS font-family value is legal here. size - The font size to use. Any valid CSS font-size value is legal here. Defaults to medium. color - The text color to use. Any valid CSS color is legal here. Defaults to #000000. weight - The font weight to use. Any valid CSS font-weight value is legal here. Defaults to normal.

util.radiusMinusBorderWidth(borderObject, radius)

Utility method to help reconcile differences in layout between CSS3 and Sliced appearances. In order to keep padding and margin values to be consistently applied, this value lets us make sure that the CSS3 implementation will have the same sizing as the sliced version.

Parameters

borderObject - a border object, such as what util.border would return radius - an int specifying the border radius on the relevant corners
