Upkfile is the list of dependencies. It's like this:

dependencies [
  git "keroxp/UniCommon", "^0.0.7"
  git "neuecc/UniRx", null,
    include: [
      src: "Assets/Plugins/*", dest: "Assets/"
    ]
  upk "SDUnity-Chan", "http://unity-chan.com/download/download.php?id=SDUnityChan&v=1.01"
  upk "Unity-Chan-Toon-Shader", -> zip "http://unity-chan.com/download/download.php?id=UTS2_0&v=2.0.3"
  upk "SocialConnector", -> git "anchan828/social-connector"
]

The file looks like DSL but is actually pure CoffeeScript file.

git (urlLike: string, semver?: string, opts?)

git is the resolver for remote git repository. It will clone repository into UpkModules folder and then copy specified files into Assets folder.

Any valid git can be accepped for urlLike 1st argument. If repository exists on Github, :user/:repo style also can be accepted.

semver for second argument is semantic version range for package.

opts is optional argument that describe which file should be copied into Assets folder.

include: {src: string, dest: string}[]

exclude: string[]

upk (assetName: string, resolver: string | () => Promise\<string>)

upk is the resolver for remote unitypackage file. Downloading upk file, extract assets into specified location that are described in unitypackage file.

assetName is used for identifier of the asset and for directory name of package.

resolver is url-like string or resolver function of upk file.

If url-like string was given, then download file from the url and extract it directory. If any async function that returns Promise<string> was given, then extract assets from the promised file or directory.

You can pass zip and git resolver by default. Both will promise resolved resouce directory by downloading remote files.

upk resolver search for .unitypackage file in resolved path. If resolved path is a file, then check it whether has .unitypackage extension. If is a directory, it search by glob {,*/}*.unitypackage pattern. That will find file in the root directory and its all first subdirecties.

Extraction of unitypackage file will be done by its own way. Just like opening it with Unity application, all asset files will be located into Assets folder.

asset(name: string, resolver: string | () => Promise, opts)

asset resolver copy specified file. Except for there are no version control, it has almost same feature with git.

zip(urlLike: string, pathResolver?: () => string)

zip resolver will download zip file and extract it into module directory.
Execution of this resolver is not permitted on the root context. This can only be passed for 2nd argument of zip and asset resolver. zip itself just download and extract zip file.

pathResolver is optional argument. It determines root directory of extracted files. By default, extracted directory will be used.
