Given a Habitat package identifier, create a Graphviz .dot representation of packages' dependencies.
To view the output on a Mac, assuming the dot program is installed:
hab-pkg-viz core/myapp | dot -Tpng | open -f -a Preview.app
The package in question must already be installed.
You can install it with Habitat by running hab install smith/hab-pkg-viz then
run with hab pkg exec smith/hab-pkg-viz hab-pkg-viz myorigin/mypackage.
To make a graph of build dependencies instead of runtime dependencies, set
HAB_PKG_VIZ_DEPS_FILE="BUILD_DEPS" when running the program.
You will only get a complete graph when all of the packages build dependencies are already installed.
This is a simple script that traverses the packages' DEPS files and writes a string that's a valid .dot representation.
Another way to do this might be by querying the depot API for the dependencies, which wouldn't require any packages to be installed.
Any changes or suggestions are welcome.
This image is a graph of runtime dependencies of hab-pkg-viz package itself.
