I'm new to Mustache.
Many templating languages (e.g., Django / Jinja ) will let you extend a "parent" template like so...
base.html
<html><head></head>
<body>
{% block content %}{% endblock %}
</body>
</html>
frontpage.html
{% extends "base.html" %}
{% block content %}<h1>Foobar!</h1>{% endblock %}
I'm aware of Mustache's partials (e.g., {{>content}} ), but those seem to be just includes .
Does template extension exist for Mustache? Or, failing that, is there at least some design pattern that effectively turns includes into template extension equivalents.

I recently found myself in the same boat, except I came from a mako background.
ReplyDeleteMustache does not allow for template extension/inheritance but there are a few options available to you that I know of.
You could use partials:
{{>header}}
Hello {{name}}
{{>footer}}
You could inject template pre-processing functions into the context for each template that needs to inherit from some other page:
{{#extendBase}}
Hello {{name}}
{{/extendBase}}
Hash:
{
"name": "Walden",
"extendBase": function() {
return function(text) {
return "<html><head></head>" + render(text) + "</body></html>"
}
}
}
Prepend and append the desired HTML to the relevant pages in your controller.
Have a layout template ala:
{{>header}}
{{{body}}}
{{>footer}}
And render the body in your controller, passing that to the layout template as a variable named body.
Implement template inheritance, pre-mustache, in your code that loads templates.
I wouldn't, however, use the triple mustache because I don't want unescaped HTML to be appearing anywhere, it's just too risky in my opinion.
If someone else has a better solution to this problem I'd love to hear it as well, since I haven't yet taken the plunge in any one of these directions.
You could use variables containing HTML. A "triple mustache" like {{{variable}}} will return unescaped HTML. It's not exactly the same as template extensions, but you could render frontpage-content.html and then put its output in a content variable that gets passed to base.html.
ReplyDelete(I added -content to the frontpage.html filename with the expectation that such a naming pattern will help keep the filenames manageable.)
If you're happy with a server-side only code, Nun is a Mustache-like templating system with extends functionality via its 'template overrides' feature - modelled on django. While it works, however, it is no longer maintained by its author.
