Create Xcode Playgrounds for the Swift programming language with rich documentation generated from Markdown
Swift code is extracted from the Markdown with the same syntax used to specify languages for code blocks in GitHub-flavored Markdown. All other text is parsed normally as Markdown using marked.
# A Swift Tour
Tradition suggests that the first program in a new language should print the words "Hello, world"
on the screen. In Swift, this can be done in a single line:
```swift
println("Hello, world!")
```

This tool requires Node.js. Download the installer from the Node.js website and follow the instructions.
-
In your Terminal, run the following command to install the Playground Builder:
$ npm install -g swift-playground-builder
-
That's it! You should now be able to use the
playground
command.
Usage: playground <paths>... [options]
paths Markdown files(s), or directory containing Markdown files,
from which to build the Playground(s)
Options:
-d, --destination Directory in which to output the Playground(s);
defaults to the current working directory
-p, --platform Specifies which platform's frameworks can be imported
in the Playground(s); only one platform can be choosen
[options: ios, osx] [default: osx]
-n, --noreset Don't allow edited code to be reset from the
"Editor → Reset Playground" menu in Xcode
-v, --version Print swift-playground-builder version and exit
You can also import the Playground Builder as a Node.js module.
var buildPlayground = require('swift-playground-builder');
-
paths
(String
orArray
, required) Path to Markdown file or directory containg Markdown files. An array of file and/or directory paths is also acceptable. -
outputDirectory
(String
, optional) Path to directory in which to output the built Playground(s). If not specified, the value ofprocess.cwd()
is used by default. -
options
(Object
, optional) See the "Options" section below for available options. -
callback
(Function
, optional) Function to be called once all Playground files have been output. First argument iserr
which contains anError
, if any.
-
allowsReset
(default:true
) A Playground's code can be modified and saved. The Playground can be reset to its original code from the "Editor → Reset Playground" menu. This menu can be disabled for a Playground by setting this option tofalse
.` -
platform
(default:osx
) Set the platform toosx
orios
to be able to import each platform's respective frameworks.
var buildPlayground = require('swift-playground-builder');
// outputs `Introduction.playground` to CWD
buildPlayground('Introduction.md');
// outputs `Variables.playground` to `/User/json/Playgrounds`
buildPlayground('Variables.md', '/User/jason/Playgrounds');
// outputs `Constants.playground` and `Closures.playground` to CWD
buildPlayground(['Constants.md', 'Closures.md'], {
allowsReset: false,
platform: 'ios'
});
// outputs playgrounds for Markdown files in `./playgrounds` directory,
// then invokes callback function
buildPlayground(['./playgrounds'], function(err) {
if (err) { throw err; }
console.log('Done building playgrounds!');
});
