Style
Given a Domain schema (specifying the domain of the diagram), a Substance file specifies how the objects and relationships in any given Substance program should get translated into graphical icons and geometric relationships on a 2D canvas.
A Style program is composed of blocks, of which there are three types:
- Namespaces are usaully used to specify constants such as canvas dimensions, colors, and other constant values within the diagram.
- Selector blocks match on Substance statements and specifies shapes and diagram layout.
- Collector blocks are similar to Selector, except that it aggreggates the match results into collections.
