clojure.walk2

A reimplementation of the clojure.walk namespace.

Submitted as an enhancement to Clojure in CLJ-1239.

This repo is for demonstration only. All further development/discussion should happen on Clojure's JIRA and mailing list.

Differences from the original clojure.walk:

  • Protocol-based dispatch for better performance

  • Support for records (also implemented for the old clojure.walk in CLJ-1105, applied in Clojure 1.6)

Releases and Dependency Information

No binary releases.

Run lein install in this directory, then use this dependency in a Leiningen project:

[com.stuartsierra/clojure.walk2 "0.1.0-SNAPSHOT"]

Usage

(require '[clojure.walk2 :as walk])

The public API is identical to that of clojure.walk.

See clojure.walk API documentation

Tests

In this directory, run lein test. The test suite is the same as that for clojure.walk, with some added tests for records.

Benchmarks

In this directory, start a repl with lein repl and then:

(require 'bench)
(bench/bench 5)

Pass different numbers to bench/bench to run the test with different random seeds. Call bench/data with the same random seed to see the test data.

In my tests, clojure.walk2 is about 2 times faster than clojure.walk.
