How do I render a array about nustache HOT 3 CLOSED

Never thought of this before so expected there wouldn't be a way, but I just wrote this test and it passed:

[Test]
public void It_can_render_arrays()
{
    var result = Render.StringToString("before{{#.}}{{.}}{{/.}}after", new[] { 1, 2, 3 });
    Assert.AreEqual("before123after", result);
}

The trick is knowing that {{.}} renders the current item in an array. I knew that would work. What I was surprised by was that it works as a key for sections, too.

Not sure if other Mustache implementations work the same way, but I'll close this unless you re-open it telling me it's wrong.

how did i ever forget that information awwwhh man. I need to writedown that . represents the current context when using mustache. thanks @jdiamond i also have another programming (but related to Nustache) question for a model like below
`Todo

• Id
• Name
• ParentId`

For a List<Todo> I need to find the children for the current todo and render them with some identation. I came up with below pseudo template
{{#.}}<div><h3>Parent Todo</h3>{{Name}}NOW HOW TO RENDER CHILD TODO</div>{{/.}}
how do I find the child Todo for the current todo from the List<Todo> inside a Mustache template? children can be found using programming code like below but no ideas as to how inside a template
instance.FindAll(delegate(todo){ return todo.ParentId == theParent.Id; })

where theParent is the current parent element for which children are seeked

I'm afraid Mustache was purposely designed to avoid "polluting" your templates with that kind of code. You're going to need to transform your flat list of Todo objects into a hierarchical tree and use that tree from the templates. A lot of people call this creating a View Model or a Presentation Model. Mustache practically requires it for any non-trivial example.

I haven't had to do recursive templates with Mustache yet, so I tried to create an example and was really surprised (and a little disgusted) with how difficult it was.

Take a look at Example_Tree.cs in the Nustache.Core.Tests project. The transformation from flat list to hierarchical tree happens in GetNodeTree(). The recursive template is in the test method and is pretty nasty. It also uses an extension to Mustache that, as far as I know, is only available in Nustache. If you need compatibility with other implementations, you can just move the inline template definition into an external template.

If you (or anybody else) knows how this can be improved, please let me know. This is a real bummer.
