mustache-haskell-0.1.0.2: README.md

# mustache-haskell

A Haskell implementation of mustache templates.

Should be compatible with the the [mustache
specification](http://mustache.github.io/mustache.5.html).


## Install

You need the Haskell platform on your system.

```
cabal install mustache
```

Or alternatively

``` 
git clone git@github.com:danchoi/mustache-haskell.git
cd mustache-haskell
cabal sandbox init
cabal install
# Now copy .cabal-sandbox/bin/mus to your PATH
```

## Usage

```
mus template.mustache < input.json
```

```
mus v0.1.0.2

Usage: mus [-c] [-d TEMPLATE_DIRECTORY] TEMPLATE_FILE
  A Haskell implementation of Mustache templates. On STDIN provide the JSON to
  insert into the template.

Available options:
  -h,--help                Show this help text
  -c                       Just output parse tree of template file
  -d TEMPLATE_DIRECTORY    Template directory
```

## List separator syntax

mustache-haskell adds one additional feature to the mustache specification.  If
you are outputing elements of a list, you can designate an optional list
separator with the following syntax:


```
{{#hobbies, }}{{#name}}{{/hobbies}}
```

This designates `", "` as the list separator and will output

```
sewing, brewing, cooking
```

when the input is 

```json
{"hobbies":[{"name":"sewing"},{"name":"brewing"},{"name":"cooking"}]}
```
