lein-ns-dep-graph

This is a Leiningen plugin to show the namespace dependencies of Clojure project sources as a graph.

Acknowledgements

The plugin itself is tiny, all the hard work is done by clojure.tools.namespace and Rhizome.

Requirements

You will need to have Graphviz installed. Run dot -V at the command line to check.

Installation and Usage

Put [lein-ns-dep-graph "0.4.0-SNAPSHOT"] into the :plugins vector of your :user profile, or if you are on Leiningen 1.x do lein plugin install lein-ns-dep-graph 0.4.0-SNAPSHOT. Then run

lein ns-dep-graph

from a Clojure project directory. This outputs a file ns-dep-graph.png showing the internal namespace dependencies of the project's .clj sources. Dependencies on external namespaces, say clojure.java.io, are not shown.

Command-Line Options

-platform

Specify :cljs as the platform argument to generate a graph for ClojureScript:

lein ns-dep-graph -platform :cljs # or
lein ns-dep-graph -platform :clj # (default)

-parents

Specify -parents to generate a graph showing only the nodes that have (one of) those namespaces as their transitive parent:

lein ns-dep-graph -parents [my-app.module.b.core]

-name

Output to the file NAME.png instead of ns-dep-graph.png.

-format

A clojure form representing a unary function that will be applied to each namespace label. For example:

; Remove project prefix from dep labels
lein ns-dep-graph -format '(fn [label] (.replace label "com.example-project." ""))'

Examples

Below is the namespace dependency graph obtained for Hiccup.
