==============
An extension of the mustache text template engine for .NET. An extension of the mustache text template engine for .NET.

## Overview
Generating text has always been a chore. Either you're concatenating strings like a mad man or you're getting fancy with `StringBuilder`. Either way, the logic for conditionally including values or looping over a collection really obscures the intention of the code. A more declarative approach would improve your code big time. Hey, that's why server-side scripting got popular in the first place, right?
[mustache](http://mustache.github.com/) is a really simple tool for generating text. .NET developers already had access to `String.Format` to accomplish pretty much the same thing. The only problem was that `String.Format` used indexes for placeholders: `Hello, {0}!!!`. **mustache** let you use meaningful names for placeholders: `Hello, {{name}}!!!`.
**mustache** is a logic-less text generator. However, almost every time I've ever needed to generate text, I needed to turn some of it on or off, depending on a value. Not having the ability to turn things off usually meant going back to building my text in parts.
Introducing [handlebars.js](http://handlebarsjs.com/). If you've needed to generate any HTML templates, **handlebars.js** is a really awesome tool. Not only does it support an `if` and `each` tag, it lets you define your own tags! It also makes it easy to reference nested values `{{Customer.Address.ZipCode}}`.
**mustache#** brings the power of **handlebars.js** to .NET and then takes it a little bit further. Not only does it support the same tags, it also handles whitespace intelligently. **mustache#** will automatically remove lines that contain nothing but whitespace and tags. This allows you to make text templates that are easy to read.
Hello, {{Customer.Name}}
{{#with Order}}
{{#if LineItems}}
Here is a summary of your previous order:
{{#each LineItems}}
{{ProductName}}: {{UnitPrice:C}} x {{Quantity}}
{{/each}}
Your total was {{Total:C}}.
{{#else}}
You do not have any recent purchases.
{{/if}}
{{/with}}
Most of the lines in the previous example will never appear in the final output. This allows you to use **mustache#** to write templates for normal text, not just HTML/XML.
## Placeholders
The placeholders can be any valid identifier. These map to the property names in your classes.
### Formatting Placeholders
Each format item takes the following form and consists of the following components:
{{identifier[,alignment][:formatString]}}
The matching braces are required. The alignment and the format strings are optional and match the syntax accepted by `String.Format`. Refer to [String.Format](http://msdn.microsoft.com/en-us/library/system.string.format.aspx)'s documentation to learn more about the standard and custom format strings.
