A code block can be either of three things: swift, highlight-swift, or print-swift. 4 | 5 | A file is transformed like this: first, all `swift` code-blocks are assembled into one big swift file. Then, for every print-swift block, a new file is generated, containing the `swift` code blocks and the contents of that print-swift block. 6 | 7 | To install, just run `pod install`, it will install the dependencies (cmark, CommonMark and LiterateSwift). For `cmark`, you need to have `cmake` installed. All code is written using the latest Xcode (Xcode 7, Beta 4). 8 | 9 | ### Weaving 10 | 11 | Additionally, you can include snippets from other swift files in subdirectories (or the same directory). 12 | 13 | If you surround your code like this: 14 | 15 | // <> 16 | class View { 17 | var window: Window 18 | init(window: Window) { 19 | self.window = window 20 | } 21 | } 22 | class Window { 23 | var view: View? 24 | } 25 | // <> 26 | 27 | And put it in a file with the extension .swift, somewhere in the same directory as the markdown file (or a subdirectory), you can then include it in your Markdown file, inside a code block: 28 | 29 | ```highlight-swift 30 | <> 31 | ``` 32 | --------------------------------------------------------------------------------
