This is a Slack User that makes available to your Slack channel the ri command, so you can consult the RDoc directly from Slack.
First run the following command to setup your app:
bin/setup
Then you have to set SLACK_URL and SLACK_TOKEN environment variablesso the app knows where to connect and finally just run:
bin/slack_user
And you are good to go!
On Slack type:
user [11:52 PM]
@bot Array#first
And the bot replies with the definition like the following:
bot [11:52 PM]
@user, here is the documentation for:
*Array#first*
(from ruby core)
------------------------------------------------------------------------------
ary.first -> obj or nil
ary.first(n) -> new_ary
------------------------------------------------------------------------------
Returns the first element, or the first n elements, of the array. If the array
is empty, the first form returns nil, and the second form returns an empty
array. See also Array#last for the opposite effect.
a = [ "q", "r", "s", "t" ]
a.first #=> "q"
a.first(2) #=> ["q", "r"]
