--[[
-- `itte_handlers`
-- Define any custom handlers in a new table, then assign the table to it.
-- Handlers can also be added to it directly e.g. `itte_handlers.hello()`.
-- Handler names should correspond to the service code name, e.g. a function
-- `itte_handlers.hello()` will be called within chat as
-- `[command_prefix]hello`, as in `!hello`.
--
-- Here an object called `h` is created for convenience, and functions will be
-- added to it.
--]]
local h = {}


-- Reply with a random greeting.
-- The handler takes two parameters, `cxt` and `msg`.
--
-- The first is a context table that includes server details and a reference to
-- the socket connection. The other is a message table, which is the IRC user
-- message broken down into parts such as the sender, recipient, reply_to, and
-- the code trigger used.
--
-- The context and message tables are required for the `message()` function to
-- know which server and user to direct a response.
--
-- The `message()` function takes the server connection from the context table,
-- a table of users or channels to reply to, and the text string, then formats
-- the string into an IRC command and sends it to the server.
--
-- `util.pick()` is a helper function that takes a table of items and picks one
-- randomly by default if the number of items is unspecified. It will return
-- the items in a table, so `[1]` will get the one (and in this case, only)
-- value in the table.
function h.hello(cxt, msg)
  irc.message(cxt, { msg.reply_to }, util.pick(hello_words)[1])
end


-- This is a task handler for a task named "hello" in the sample config, and is
-- an alias to the hello() function above.
function h.th_hello(cxt, msg)
  h.hello(cxt, msg)
end


-- Hook up the handlers.
