ragno

A crawler for extracting info from web domains

Usage

Copy and edit the configuration file

cp ragno-sample.edn ragno.edn

Invoke a library API function from the command-line:

$clojure -X net.clojars.matteoredaelli.ragno/cli :urlfile \"urls.csv\"  :config-file \"ragno.edn\"

Using Redis or Apache kvrocks or Snap KeyDB

$clojure -X net.clojars.matteoredaelli.redis/cli :config-file \"ragno.edn\"

$redis-cli publish ragno "https://www.redaelli.org/"

Run the project's tests (they'll fail until you edit them):

$ clojure -T:build test

Run the project's CI pipeline and build a JAR (this will fail until you edit the tests to pass):

$ clojure -T:build ci

This will produce an updated pom.xml file with synchronized dependencies inside the META-INF directory inside target/classes and the JAR in target. You can update the version (and SCM tag) information in generated pom.xml by updating build.clj.

Install it locally (requires the ci task be run first):

$ clojure -T:build install

Deploy it to Clojars -- needs CLOJARS_USERNAME and CLOJARS_PASSWORD environment variables (requires the ci task be run first):

$ clojure -T:build deploy

Your library will be deployed to net.clojars.matteoredaelli/ragno on clojars.org by default.
