This project is a small utility to create a relationship graph for protocols, classes and structs in a Swift codebase.

Examples

Alamofire

Haneke

ObjectMapper

Requirements

• NodeJS >= 6.5.0
• Graphviz's dot

Installation

1. Ensure your NodeJS version is 6.5.0 or later.
2. Install Graphviz's dot command line utility.
   • On macOS you can install it with brew:

   brew install graphviz
   

3. Install package dependencies: npm install.

Installation

Until this is published in NPM registry...

git clone git@github.com:Sumolari/swift-relationship-graph.git
cd swift-relationship-graph
npm install -g .

Usage

swift-relationship-graph <pathToJSON> [<operation>, <type...>, <pathToOutputFile>]

Where filename is the path to a SourceKitten's documentation JSON.

• Available operations:
  • dotGraphCode
  • dotGraphPDF
  • graph (default, equivalent to dotGraphPDF)
• Available types (multiple values allowed, comma separated):
  • protocols (default)
  • structs
  • classes

Getting SourceKitten documentation JSON

Ensure you have SourceKitten properly installed and check its usage guide.

Example:

sourcekitten doc -- -workspace Haneke.xcworkspace -scheme Haneke

Examples

Check examples folder to see some demos.

Run each .sh file to automatically download and generate the relationsip diagram of each Open Source sample project.

Todo

• Improve README
• Add proper error messages
• Add examples
• Call SourceKitten automatically
  • Not a priority, better add support to integrate graph generation in an Xcode plugin.
• Improve documentation
• Publish to NPM registry
• Add support for classes' dependency graph
• Made it -g-compatible
• Add legend
• Add support for generating UML class-like diagrams
• Add unit tests
• Add support for filtering by entity (tree mode)
