EFMarkdown is a lightweight Markdown library in Swift, based on [EFCMark](https://github.com/EFPrefix/EFCMark), inspired by [markdown](https://github.com/vapor-community/markdown) and [Markoff](https://github.com/thoughtbot/Markoff).

## Installation

EFMarkdown is available through [CocoaPods](http://cocoapods.org). To install
it, simply add the following line to your Podfile:

```ruby
pod "EFMarkdown"
```

## Usage

### 1. Markdown to HTML

You can use `EFMarkdown` to make Markdown string to HTML string easily:

```swift
let markdown = "# Hello"
var html = ""
do {
html = try EFMarkdown().markdownToHTML(markdown, options: EFMarkdownOptions.safe)
print(html) // This will return "

Hello

\n"
} catch let error as NSError {
print ("Error: \(error.domain)")
}
```

### 2. View Markdown

You can use `EFMarkdownView` to make a preview of Markdown:

```swift
let screenSize = UIScreen.main.bounds
let markView = EFMarkdownView()
markView.frame = CGRect(x: 0, y: 20, width: screenSize.width, height: screenSize.height - 20)
markView.onRendered = {
[weak self] (height) in
if let _ = self {
// Optional: you can know the change of height in this block
print("onRendered height: \(height ?? 0)")
}
}
self.view.addSubview(markView)
markView.load(markdown: testMarkdownFileContent(), options: [.default]) {
[weak self] (_, _) in
if let _ = self {
// Optional: you can change font-size with a value of percent here
markView.setFontSize(percent: 128)
printLog("load finish!")
}
}
```

### 3. Options

You can pass different options to the underlying `cmark` library. By default `safe` is passed.

The available options are:

* default
* sourcePos
* hardBreaks
* safe
* noBreaks
* validateUTF8
* smart
* githubPreLang
* liberalHtmlTag

For more information on the available options, see [`cmark`](https://github.com/github/cmark).
