HotMilk v1.1

About

HotMilk is a hierarchical template-management library based on the Pieter van de Bruggen's Milk (the CoffeeScript implementation of Mustache templates).

This work was inspired mostly by ICanHaz library and, indeed, is just a generalization of its authors' ideas.

HotMilk allows you to organize your templates and partials in a handy tree structure and use them as easy as calling functions.

Usage

You can use HotMilk in browser or server environment. Browser versions have additional feature: auto-grabbing templates from <script> html-tags.

HotMilk provides handy interface to invoke Milk.render() function, for example:

    htmlText = HotMilk.greetings({ ... user ... });
    htmlText = HotMilk.books.list([ ... list of books ... ]);
    htmlText = HotMilk.books.details({ ... book ... });
    htmlText = HotMilk.movies.list([ ... list of movies ... ]);

To add a template, invoke HotMilk.$addTemplate() and pass it template path and template text itself:

    HotMilk.$addTemplate('books/list', '... mustache template ...');
    HotMilk.$addTemplate('books/details', '... mustache template ...');
    HotMilk.$addTemplate('greetings', '... mustache template ...');

Partial templates have scopes: you can add partial which will be visible to only one template, or to group of templates, or to all templates in your template set:

    HotMilk.$addTemplate('books/list#item', '...'); // for HotMilk.books.list() only
    HotMilk.$addTemplate('books#author', '...');    // for list and details templates
    HotMilk.$addTemplate('#price', '...');          // global partial template
    // partial "overloading"
    HotMilk.$addTemplate('movies#price', '...');    // movies will have their own price format

You can add/delete template relatevely to the existing group or template:

    HotMilk.movies.$addTemplate('#price', '...');   // same as above
    HotMilk.books.$removeTemplate('list');

Partial templates can also be invoked directly. In this case all the partials available to its parent are also available. Do this in the following way:

    AddLI(HotMilk.movies.list.$.item({ ... movie ... }));

You can have any (reasonable) number of hierarchy levels (well, 'path/which/is/too/long/like/this#is' is possible but doesn't seem very usable).

Templates and partials can be added in any order, so you can load templates asynchronously.

Deleting templates is also possible: just call HotMilk.$removeTemplate('path/to/it'). Again, you can remove templates in any order: the only one at a time will be removed leaving others untouched (even partials will survive killing their parent and creating it again if needed).

Template path restrictions

• You cannot create a template under another one:

        HotMilk.$addTemplate('movies', '...');
        HotMilk.$addTemplate('movies/details', '...'); // forbidden

• Each path element (template name, group name, partial name) must be correct javascript identifier: contain upper- and lowercase letters, digits, underscore and dollar and don't start with digit

• Also, names must not start with dollar sign as it is used for HotMilk methods (partials could, actually)

Template grabbing in browser

As ICanHaz do, HotMilk also performs automatic template grabbing after dom is ready.

Initially this was thought as the main feature. Even the name was choosen because of this: it supposed to mean 'HTML-embedded Milk', HoTMiLk. But later things changed and crooked 'HoTMiLk' became just 'HotMilk'

You can write templates directly in your HTML-code as <script> tags:

    <script type="text/x-mustache-template" data-hotmilk-path="books/list#item">
        <a href='/books/{{id}})'><b>{{title}}</b> by {{#author}}{{>author}}{{/author}}</a>
    </script>

Just use "text/x-mustache-template" as your script type and provide template path as HTML5-data attribute "data-hotmilk-path".

If you want to add a template to several locations (e.g. date template for newspapers and magazines but not for books, poscards, movies, games, music etc) you can just write all the pathes in the 'data-hotmilk-path' attribute separating them with colon:

    <script type="text/x-mustache-template" data-hotmilk-path="newspapers#date:magazines#date">
        {{weekOfYear}}, {{monthName}} {{year}}
    </script>

Using cold Milk

You still can access the Milk through HotMilk.$Milk if you want. The most obvious use case for this is adding a global helper. Please note: there is almost no sense in adding global partials to HotMilk.$Milk.partials because they will be ignored when using HotMilk.
