kltool for python, toolset for web, http, cache, dht, xml, json and so on

PYKL is the kltool for python, toolset for web, http, cache, dht, xml, json and so on.

Install it typing in your console:

pip install pykl

Usage

You can either do pykl --test to start a test server for testing queries or

pykl QUERY_FILE

This command will write in the standard output (or other output if specified via --output) the resulting JSON.

Your QUERY_FILE could look similar to this:

{
  page(url:"http://news.ycombinator.com") {
    items: query(selector:"tr.athing") {
      rank: text(selector:"td span.rank")
      title: text(selector:"td.title a")
      sitebit: text(selector:"span.comhead a")
      url: attr(selector:"td.title a", name:"href")
      attrs: next {
         score: text(selector:"span.score")
         user: text(selector:"a:eq(0)")
         comments: text(selector:"a:eq(2)")
      }
    }
  }
}

Advanced usage

If you want to generalize your pykl query to any page, just rewrite your query file adding the $page var. So should look to something like this:

query ($page: String) {
  page(url:$page) {
    # ...
  }
}

And then, query it like:

pykl QUERY_FILE http://news.ycombinator.com
