Global Functions

`new_from_discovery( desc, [, { options }] )`

Instanciate a ReST client from a Google Discovery Document defined by an URL or a table with keys api and version.

The optional table options allows to overwrite some parameters of the description (see new_from_spec).

local discovery = require 'Spore.GoogleDiscovery'
local client = discovery.new_from_discovery 'https://www.googleapis.com/discovery/v1/apis/urlshortener/v1/rest'

local client = discovery.new_from_discovery { api = 'urlshortener', version = 'v1' }

`convert( gdoc )`

Converts a Google Discovery Document into a Spore Specification (both are represented by a table).

Utilities

`discovery2spore url`

Converts a Google Discovery Document into a Spore Specification. By this way, the Spore specification could be edited/modified before use.

$ discovery2spore https://www.googleapis.com/discovery/v1/apis/urlshortener/v1/rest > urlshortener.json

    api = 'translate',
    version = 'v2',
}
client:enable 'Format.JSON'
client:enable('Parameter.Force', { key = '===========<INSERT-YOUR-KEY>===========' })
client.translate = client.translations_list -- alias

local r = client:translate{ source='en', target='fr', q=[[Hello World]] }
for _, v in ipairs(r.body.data.translations) do
    print(v.translatedText)
end

local r = client:apis_list()
for _, item in ipairs(r.body.items) do
    print(item.name, item.version)
end
