| * Template code |
| * |
| * A template is just a javascript structure. An element is represented as: |
| * |
| * [tag_name, {attr_name:attr_value}, child1, child2] |
| * |
| * the children can either be strings (which act like text nodes), other templates or |
| * functions (see below) |
| * |
| * A text node is represented as |
| * |
| * ["{text}", value] |
| * |
| * String values have a simple substitution syntax; ${foo} represents a variable foo. |
| * |
| * It is possible to embed logic in templates by using a function in a place where a |
| * node would usually go. The function must either return part of a template or null. |
| * |
| * In cases where a set of nodes are required as output rather than a single node |
| * with children it is possible to just use a list |
| * [node1, node2, node3] |
| * |
| * Usage: |
| * |
| * render(template, substitutions) - take a template and an object mapping |
| * variable names to parameters and return either a DOM node or a list of DOM nodes |
| * |
| * substitute(template, substitutions) - take a template and variable mapping object, |
| * make the variable substitutions and return the substituted template |
| * |
