       mustache - Logic-less templates.


       A typical Mustache template:

           Hello {{name}}
           You have just won {{value}} dollars!
           Well, {{taxed_value}} dollars, after taxes.

       Given the following hash:

             "name": "Chris",
             "value": 10000,
             "taxed_value": 10000 - (10000 * 0.4),
             "in_ca": true

       Will produce the following:

           Hello Chris
           You have just won 10000 dollars!
           Well, 6000.0 dollars, after taxes.


       Mustache can be used for HTML, config files, source code - anything. It works by expanding
       tags in a template using values provided in a hash or object.

       We call it "logic-less" because there are no if statements, else clauses,  or  for  loops.
       Instead there are only tags. Some tags are replaced with a value, some nothing, and others
       a series of values. This document explains the different types of Mustache tags.


       Tags are indicated by the double mustaches. {{person}} is a tag,  as  is  {{#person}}.  In
       both  examples, we´d refer to person as the key or tag key. Let´s talk about the different
       types of tags.

       The most basic tag type is the variable. A {{name}} tag in a basic template  will  try  to
       find  the  name  key  in the current context. If there is no name key, the parent contexts
       will be checked recursively. If the top context is reached and the name key is  still  not
       found, nothing will be rendered.

       All  variables  are  HTML  escaped  by default. If you want to return raw contents without
       escaping, use the triple mustache: {{{name}}}.

       You can also use & to return its raw  contents:  {{&  name}}.  This  may  be  useful  when
       changing delimiters (see "Set Delimiter" below).

       By  default  a  variable "miss" returns an empty string. This can usually be configured in
       your Mustache library. The Ruby version of Mustache supports raising an exception in  this
       situation, for instance.


           * {{name}}
           * {{age}}
           * {{company}}
           * {{{company}}}


             "name": "Chris",
             "company": "<b>GitHub</b>"


           * Chris
           * &lt;b&gt;GitHub&lt;/b&gt;
           * <b>GitHub</b>

       Sections  render  blocks  of text zero or more times, depending on the value of the key in
       the current context.

       A section begins with a pound and ends  with  a  slash.  That  is,  {{#person}}  begins  a
       "person" section while {{/person}} ends it.

       The behavior of the section is determined by the value of the key.

       False Values or Empty Lists

       If  the  person key exists and has a value of false or an empty list, the HTML between the
       pound and slash will not be displayed.


             Never shown!


             "person": false



       Non-Empty Lists

       If the person key exists and has a non-false value, the HTML between the pound  and  slash
       will be rendered and displayed one or more times.

       When  the value is a non-empty list, the text in the block will be displayed once for each
       item in the list. The context of the block will be  set  to  the  current  item  for  each
       iteration. In this way we can loop over collections.




             "repo": [
               { "name": "resque" },
               { "name": "hub" },
               { "name": "rip" }




       When  the  value  is  a  callable object, such as a function or lambda, the object will be
       invoked and passed the block of text. The text passed is the  literal  block,  unrendered.
       {{tags}}  will  not have been expanded - the lambda should do that on its own. In this way
       you can implement filters or caching.


             {{name}} is awesome.


             "name": "Willy",
             "wrapped": function() {
               return function(text, render) {
                 return "<b>" + render(text) + "</b>"


           <b>Willy is awesome.</b>

       Non-False Values

       When the value is non-false but not a list, it will be used as the context  for  a  single
       rendering of the block.


             Hi {{name}}!


             "person?": { "name": "Jon" }


           Hi Jon!

   Inverted Sections
       An  inverted  section begins with a caret (hat) and ends with a slash. That is {{^person}}
       begins a "person" inverted section while {{/person}} ends it.

       While sections can be used to render text zero or more times based on  the  value  of  the
       key,  inverted  sections  may render text once based on the inverse value of the key. That
       is, they will be rendered if the key doesn´t exist, is false, or is an empty list.


             No repos :(


             "repo": []


           No repos :(

       Comments begin with a bang and are ignored. The following template:

           <h1>Today{{! ignore me }}.</h1>

       Will render as follows:


       Comments may contain newlines.

       Partials begin with a greater than sign, like {{> box}}.

       Partials are rendered at runtime (as opposed to compile time), so recursive  partials  are
       possible. Just avoid infinite loops.

       They also inherit the calling context. Whereas in ERB you may have this:

           <%= partial :next_more, :start => start, :size => size %>

       Mustache requires only this:

           {{> next_more}}

       Why?  Because the next_more.mustache file will inherit the size and start methods from the
       calling context.

       In this way you may want to think of partials as includes,  or  template  expansion,  even
       though it´s not literally true.

       For example, this template and partial:

             {{> user}}


       Can be thought of as a single, expanded template:


   Set Delimiter
       Set  Delimiter  tags start with an equal sign and change the tag delimiters from {{ and }}
       to custom strings.

       Consider the following contrived example:

           * {{default_tags}}
           {{=<% %>=}}
           * <% erb_style_tags %>
           <%={{ }}=%>
           * {{ default_tags_again }}

       Here we have a list with three items. The first item  uses  the  default  tag  style,  the
       second  uses  erb  style as defined by the Set Delimiter tag, and the third returns to the
       default style after yet another Set Delimiter declaration.

       According to  ctemplates,
       this  "is useful for languages like TeX, where double-braces may occur in the text and are
       awkward to use for markup."

       Custom delimiters may not contain whitespace or the equals sign.
