smoke

smoke is a Ruby based DSL that allows you to take data from YQL, RSS / Atom (and more, if you think of a useful source). This "data" can then be re-represented, sorted and filtered. You can collect data from a multiude of sources, sort them on a common property and return a plain old ruby object or json (You could add in something to output XML too)

Media

• Presentation from Melbourne #roro
• Early screencast to get developer / peer feedback

The concept

The concept comes from using Yahoo Pipes to make little mash ups, get a list of tv shows for my torrent client, compile a recipe book or make tools to give me a list of albums that artists in my music library are about to be release.

How or what to contribute

• Test everything you do
• Add a way to output (XML, anyone?)
• Examples of queries you'd like to be able to do (email / github message them to me)

API Examples

YQL

# This will use yahoo search to get an array of search results about Ruby
Smoke.yql(:ruby) do
  select  :all
  from    "search.web"
  where   :query, "ruby"
  
  discard :title, /tuesday/i
end

Smoke.yql(:python) do
  select  :all
  from    "search.web"
  where   :query, "python"
end

Join sources and use them together

Smoke.join(:ruby, :python)

or even

Smoke.join(:python, :ruby) do
  emit do
    sort :title
    rename :shit_name => :title
  end
end

CI

Integrity is running for smoke

TODO (working on, just mental notes)

• YQL Definitions
• Consider variable injection (eg, allow to query sending a username within some aspect of the request)
• Implement a disaptch / request method that will actually thread property (event-machine)
• Checkout experimental fakeweb version to stub out the yql specs

Later / maybe

• Allow for sources to explicitly set the content type being returned for those stupid content providers
• YQL w/oAuth
• YQL Subqueries?
