## Usage

Double clicking on the .exe will produce a `_posts` folder (if it does not already exist) and markdown files for every issue tagged `Next Release` in markdown format.

The program will strip all checkboxes away and add links to all Github issues (in the format `#123`)

<a name="setup"/>
## Setup

You can edit template.md to change the way the post is structured. [Mustache](http://mustache.github.io/) is the templating engine used.

    Note: You must include template.md in the same directory as the program as I have hardcoded the location of the file into the program.

For example, take a look at the default template

```
---
layout: no-sidebar
title: {{title}}
---
{{body}}

```

The text nested between handlebars `{{}}` are variables that will be replaced by the program. Although I only use 2 variables, you can use other variables such as `html_url` or `number` or `milestone` 
to add in more information to the release post.

The list of variables and their values that you can substitute in are the key/value pairs of the JSON object that the [GitHub API](http://developer.github.com/v3/issues/#list-issues-for-a-repository)
returns. An example of the response at the end of this [post](#json).

## Modifying the source:

This program was written in python 3.2 I have included the source code for the program inside the source code folder. Feel free to modify the program if you want.

The `exe` file was built using cxfreeze for python 3.2.
