var Butler = require('noddity-butler')
var Linkifier = require('noddity-linkifier')
var LevelJs = require('level-js')

var db = new LevelJs('noddity-posts-db')
var butler = new Butler('http://example.com/blogfiles/', db)
var linkifier = new Linkifier('#/myposts/')

var options = {
	butler: butler,
	linkifier: linkifier,
	el: 'body',
	data: {
		config: {
			configProperty: 'configValue'
		},
		arbitraryValue: 'lol'
	}
}

renderDom('post-template.html', options, function (err, setCurrent) {
	setCurrent('my-awesome-post.md', function (err) {
		if (err) throw err // 404
	})
})

api

var renderDom = require('noddity-render-dom')

renderDom(post, options, cb)

• post: a Noddity post object or a post filename
• options: all the other arguments
  • butler: a Noddity Butler
  • linkifier: a Noddity Linkifier
  • el: a selector string of the element to which the Ractive object will be bound. Optional
  • data: any properties on the data object will be made available to the templates. Optional
• cb(err, setCurrent): a function to be called when the first render is finished.

setCurrent(post, [data,] [cb])

setCurrent is a function/event emitter.

Call the function to change the current post to a different post.

• post: a Noddity post object, or a post filename
• data: any properties on the data object will be made available to the templates. Optional
• cb(err): an optional function that is called when the current post is set or a fatal error occurs. Optional

events

• error(err) is emitted on non-fatal errors, e.g. an embedded template not loading
  • err is an Error object

setCurrent('my-post.md', function (err) {
	if (err) throw err // Could not set 'my-post.md' to be the current post
})

setCurrent.on('error', function (err) {
	console.error(err) // Probably an embedded template didn't load
})

values accessible in ractive expressions

• postList: an array of post objects that have dates, ordered by date descending. Metadata is accessible on the object iself without having to use the metadata property
• posts: an object whose keys are the post file names, and whose value is the post object. Right now the keys all have periods . stripped from them due to an issue with Ractive
• removeDots: a function that takes a string as input and returns a version with dots . removed
• current: the file name of the currently displayed post (the one specified in the url). Also a partial of the current post (set by setCurrent()). Can be accessed by doing {{>current}} or {{{html}}}
• metadata: an object of the metadata of the current post. E.g. {{metadata.title}} accesses the title of the current post, even if it is in an embedded template.
• Metadata values of the template are exposed. (Except in the root post, where the current post's metadata is exposed). E.g. {{title}} accesses the title of the current.

ractive expressions example

root.html

<h1>{{title}}</h1>
<article>
	{{>current}}
</article>
Written by {{author}} on {{date.toDateString()}}.

post1.md

title: welcome
date: 2015-10-30
author: Joseph

Hey, thanks for visiting my blog!!!

::embed.md::

embed.md

title: embed

The title is: {{metadata.title}}
My title is: {{title}}

Set root.html to be the root, and post1.md to be the current post:

renderDom('root.html', options, function (err, setCurrent) {
	setCurrent('post1.md', function (err) {
		if (err) throw err // 404
	})
})

End up with something like:

<h1>welcome</h1>
<article>
	Hey thanks for visiting my blog!!!

	The title is: welcome
	My title is: embed
</article>
