Scripting

Scripting Support

OkUrl builds on the javascript support (jjs) in Java 8 to support interactive scripting (repl) and shell scripts.

Bindings

As well as existing functionality https://wiki.openjdk.java.net/display/Nashorn/Nashorn+extensions, https://docs.oracle.com/javase/8/docs/technotes/guides/scripting/nashorn/shell.html

Additions bindings are exposed

• readParam(name) - performs standard param handling, currently '@path/filename.txt' is read and replaces the param.
• query(url) - query a webservice and parse JSON response
• location() - reads OSX Core Location. This requires "brew install corelocationcli"

Interactive Script

$ okshell

jjs> var ab = query("https://api.twitter.com/1.1/statuses/home_timeline.json");
jjs> ab.filter(function(tweet) { 
  return tweet.user.screen_name == 'GuardianAus'; 
}).map(function(tweet) { 
  return tweet.text; 
});

Shell Scripts

var loc = location();

var a = query('https://api.uber.com/v1/products?latitude=${loc.latitude}&longitude=${loc.longitude}')

print(a.products[0]);
