What Is Extractor

This is a Clojure library designed to survey a Clojure codebase and extract meta information about it (in particular documentation).

It is supposed to power a new version of clojuredocs.org once the library is mature enough.

Project Maturity

The project is young and is very much work in progress.

If you are interested in helping, contact @michaelklishin and join #clojure-doc on irc.freenode.net.

To use Extractor as a library:

(ns foo
  (:require [clojuredocs.extractor.analyzer :refer :all]))

;; generate a map of clojure var metadata
(gen-clojure "/Users/hinmanm/src/clojure")

;; encode the map to json, filename is optional
(gen-clojure-json "/Users/hinmanm/src/clojure" "foo.json.gz")

;; generate a map of your project's var metadata
(gen-project-docs {:name "foo"
                   :group "org.bar"
                   :url "http://example.com"
                   :description "My thing"
                   :scm "http://github.com/foo/bar"
                   :license {:name "Eclipse Public License"
                             :url "http://www.eclipse.org/legal/epl-v10.html"}
                   :version "1.0"})

;; encode the map to json, filename is optional again
(gen-project-docs-json {...} "bar-1.0.json.gz")

;; read metadata from a file
(read-namespace (clojure.java.io/file "/Users/hinmanm/src/clj/cadastre/src/cadastre/analyzer.clj"))

;; serialize a map to a file, filename is optional
(serialize-project-info {...} "myfile.json.gz")

;; You can bind *verbose* to println status:
(binding [*verbose* true]
  (gen-clojure-json "/Users/hinmanm/src/clojure"))
