Poddotify is a command line tool written in Swift to read a Podfile.lock and generate a Dot source. The Dot source can then be processed by Graphviz, an open source graph rendering library, to generate a visualization of the dependency graph as a jpg, png, pdf or more.

For more information about Graphviz you can visit their official website https://www.graphviz.org

The command line tool will resolve the transitive closure to simplify the dependency graph and reduce the number of edges. It will also mark as a subgraph the dependencies that represents subspecs of a certain podspec or, optionally, reduce them to a single node in order to simplify the graph complexity.

USAGE:

• -i filename : specify the .lock filename to be used as input
• -o filename : output filename
• -noversion : do not include dependency version numbers (-nv)
• -nosubspecs : reduce subspecs subgraphs to a single node (-ns)
• -lefttoright : print graph left to right (-lr)
• -verbose : verbose output (-v)
• -help : usage information (-h)

By default the input filename is Podfile.lock

You can use Homebrew to install the binary directly:

brew install gabrielepalma/tools/poddotify

Alternatively, you can clone this repository, edit the sources and build and run however you see fit.
