+ dynamic loading of partials, which is particularly useful in cases where
+ polymorphic data needs to be rendered in different ways. Such cases would
+ otherwise be possible to render only with solutions that are convoluted,
+ inefficient, or both.
+
+ Example.
+ Let's consider the following data:
+
+ items: [
+ { content: 'Hello, World!' },
+ { url: 'http://example.com/foo.jpg' },
+ { content: 'Some text' },
+ { content: 'Some other text' },
+ { url: 'http://example.com/bar.jpg' },
+ { url: 'http://example.com/baz.jpg' },
+ { content: 'Last text here' }
+ ]
+
+ The goal is to render the different types of items in different ways. The
+ items having a key named `content` should be rendered with the template
+ `text.mustache`:
+
+ {{!text.mustache}}
+ {{content}}
+
+ And the items having a key named `url` should be rendered with the template
+ `image.mustache`:
+
+ {{!image.mustache}}
+
+
+ There are already several ways to achieve this goal, here below are
+ illustrated and discussed the most significant solutions to this problem.
+
+ Using Pre-Processing
+
+ The idea is to use a secondary templating mechanism to dynamically generate
+ the template that will be rendered.
+ The template that our secondary templating mechanism generates might look
+ like this:
+
+ {{!template.mustache}}
+ {{items.1.content}}
+
+ {{items.3.content}}
+ {{items.4.content}}
+
+
+ {{items.7.content}}
+
+ This solutions offers the advantages of having more control over the template
+ and minimizing the template blocks to the essential ones.
+ The drawbacks are the rendering speed and the complexity that the secondary
+ templating mechanism requires.
+
+ Using Lambdas
+
+ The idea is to inject functions into the data that will be later called from
+ the template.
+ This way the data will look like this:
+
+ items: [
+ {
+ content: 'Hello, World!',
+ html: function() { return '{{>text}}'; }
+ },
+ {
+ url: 'http://example.com/foo.jpg',
+ html: function() { return '{{>image}}'; }
+ },
+ {
+ content: 'Some text',
+ html: function() { return '{{>text}}'; }
+ },
+ {
+ content: 'Some other text',
+ html: function() { return '{{>text}}'; }
+ },
+ {
+ url: 'http://example.com/bar.jpg',
+ html: function() { return '{{>image}}'; }
+ },
+ {
+ url: 'http://example.com/baz.jpg',
+ html: function() { return '{{>image}}'; }
+ },
+ {
+ content: 'Last text here',
+ html: function() { return '{{>text}}'; }
+ }
+ ]
+
+ And the template will look like this:
+
+ {{!template.mustache}}
+ {{#items}}
+ {{{html}}}
+ {{/items}}
+
+ The advantage this solution offers is to have a light main template.
+ The drawback is that the data needs to embed logic and template tags in
+ it.
+
+ Using If-Else Blocks
+
+ The idea is to put some logic into the main template so it can select the
+ templates at rendering time:
+
+ {{!template.mustache}}
+ {{#items}}
+ {{#url}}
+ {{>image}}
+ {{/url}}
+ {{#content}}
+ {{>text}}
+ {{/content}}
+ {{/items}}
+
+ The main advantage of this solution is that it works without adding any
+ overhead fields to the data. It also documents which external templates are
+ appropriate for expansion in this position.
+ The drawback is that this solution isn't optimal for heterogeneous data sets
+ as the main template grows linearly with the number of polymorphic variants.
+
+ Using Dynamic Names
+
+ This is the solution proposed by this spec.
+ The idea is to load partials dynamically.
+ This way the data items have to be tagged with the corresponding partial name:
+
+ items: [
+ { content: 'Hello, World!', dynamic: 'text' },
+ { url: 'http://example.com/foo.jpg', dynamic: 'image' },
+ { content: 'Some text', dynamic: 'text' },
+ { content: 'Some other text', dynamic: 'text' },
+ { url: 'http://example.com/bar.jpg', dynamic: 'image' },
+ { url: 'http://example.com/baz.jpg', dynamic: 'image' },
+ { content: 'Last text here', dynamic: 'text' }
+ ]
+
+ And the template would simple look like this:
+
+ {{!template.mustache}}
+ {{#items}}
+ {{>*dynamic}}
+ {{/items}}
+
+ Summary:
+
+ +----------------+---------------------+-----------------------------------+
+ | Approach | Pros | Cons |
+ +----------------+---------------------+-----------------------------------+
+ | Pre-Processing | Essential template, | Secondary templating system |
+ | | more control | needed, slower rendering |
+ | Lambdas | Slim template | Data tagging, logic in data |
+ | If Blocks | No data overhead, | Template linear growth |
+ | | self-documenting | |
+ | Dynamic Names | Slim template | Data tagging |
+ +----------------+---------------------+-----------------------------------+
+
+ Dynamic Names are a special notation to dynamically determine a tag's content.
+
+ Dynamic Names MUST be a non-whitespace character sequence NOT containing
+ the current closing delimiter. A Dynamic Name consists of an asterisk,
+ followed by a dotted name. The dotted name follows the same notation as in an
+ Interpolation tag.
+
+ This tag's dotted name, which is the Dynamic Name excluding the
+ leading asterisk, references a key in the context whose value will be used in
+ place of the Dynamic Name itself as content of the tag. The dotted name
+ resolution produces the same value as an Interpolation tag and does not affect
+ the context for further processing.
+
+ Set Delimiter tags MUST NOT affect the resolution of a Dynamic Name. The
+ Dynamic Names MUST be resolved against the context stack local to the tag.
+ Failed resolution of the dynamic name SHOULD result in nothing being rendered.
+
+ Engines that implement Dynamic Names MUST support their use in Partial tags.
+ In engines that also implement the optional inheritance spec, Dynamic Names
+ inside Parent tags SHOULD be supported as well. Dynamic Names cannot be
+ resolved more than once (Dynamic Names cannot be nested).
