clj-hiera

Generates a graph of the dependency hierarchy of a set of clojure files. This uses the clojure.tools.namespace library for namespace parsing and Rhizome for graph generation using Graphviz.

This tool was originally inspired by lein-ns-dep-graph, but has many additional options for graph generation.

Usage

There are a few different ways to use clj-hiera. First, you'll need Graphviz installed in order to generate the images. Check your local package manager:

# Debian/Ubuntu:
sudo apt-get install graphviz

# OS X with Homebrew:
brew install graphviz

Deps Alias

If you're using tools.deps, you can use this by adding an alias to your deps.edn file:

:hiera
{:deps {io.github.greglook/clj-hiera {:git/tag "2.0.0", :git/sha "b14e514"}}
 :exec-fn hiera.main/graph
 :exec-args {,,,}}

To generate namespace graphs:

clj -X:hiera [opts]

Clojure Tool

Alternately, you can use this as a standalone Clojure tool:

clj -Ttools install-latest :lib io.github.greglook/clj-hiera :as hiera

Then, to invoke the tool in any Clojure project:

clj -Thiera graph [opts]

Leiningen

For Leiningen, you can use this via the lein-hiera plugin. Add the following to your project.clj file or user-level profile:

[lein-hiera "2.0.0"]

Then you can run:

lein hiera [opts]

Options

The available options, and their default values are:

When using Leiningen, graph generation options may be provided under the :hiera key in the project map. You can also provide/override the configuration options by specifying them on the command line with keyword arguments:

lein hiera :cluster-depth 3 :layout :horizontal

Example

This image shows the dependency hierarchy from a moderately complex project. The namespaces are clustered by two levels, and it shows a dependency on the external puget library.
