  A sample Restful JSON Client API.


  This sample demonstrates how to comunicate with an HTTP JSON 3rdparty
  API in Lua script.

  APIs demonstrated:
    * HTTP RestClient
    * JSON

--]]

-- GitHub API URL
url='https://api.github.com/repos/wtfbbqhax/tremulous/releases'

-- HTTP Get request- retrieve the raw JSON response
txt = http.get(url)
assert(txt.code == 200)

-- Decode raw JSON response into a Lua table
releases = rapidjson.decode(txt.body)

-- GitHub returned an array of releases- The "most_recent" is item 1
-- NOTE: Lua array indexing starts at `1` not `0`!!
most_recent = releases[1]

-- FIXME: Remove hardcoded tag_name in this test
assert(most_recent.tag_name == "Oct-22-2016")


for i,asset in ipairs(most_recent.assets) do
    print(asset.browser_download_url)
end
