Supported Clojure versions

Documentation & Examples

Crawlista is a work in progress. Please see our test suite for code examples. Once APIs and core functionality stabilizes, we will begin writing documentation guides and update this document.

Crawlista Is a ClojureWerkz Project

Crawlista is part of the group of Clojure libraries known as ClojureWerkz, together with Neocons, Langohr, Elastisch, Welle, Monger, Quartzite and several others.

Continuous Integration

Continuous Integration status

CI is hosted by


Crawlista uses Leiningen 2. Make sure you have it installed and then run tests against all supported Clojure versions using

lein all test

Then create a branch and make your changes on it. Once you are done with your changes and all tests pass, submit a pull request on Github.

Regenerating robots.txt Parser

If you make changes to the Ragel-based robots.txt parser in Crawlista, you need to regenerate it:

ragel -J -o src/java/clojurewerkz/crawlista/robots/ src/rl/clojurewerkz/crawlista/robots/Parser.rl
lein javac

and then run robots.txt parser test suite with

lein test :robots
