/*
|
|
* 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
|
|
*
