pechkin

An OTP application for sending messages in telegram channels.

Configuration

Number of workers

You can define max telegram workers in sys.config. By default it number of yours machine CPUs:

{pechkin, [
    {max_workers, "${MAX_WORKERS}"}
]}

Workers are taken from the pool by round-robin.

Install

In future pechkin will be distributed, but now you can include him in release.

rebar.config

Add dependency in deps section of yours rebar.config

{deps, [
        {pechkin,  {git, "git://github.com/stleon/pechkin.git", {tag, "0.0.1"}}}
       ]
}.

And in relx section add pechkin to list of applications that be included in the release:

{relx, [{release, { release_name, "vsn" },
         [sasl,
          pechkin
          ...]},

Then in app.src add pechkin:

  {applications,
   [kernel,
    stdlib,
    pechkin
   ]},

API

send(Message)

Here is some workflow (if you run from shell) :

1> rr("include/pechkin.hrl").
2> ApiKey = <<"bot_api_key">>.
3> Text = <<"Hello, world!">>.
4> Channel = <<"@channel_name">>. %% or id
5> Message = #telegram_message{apikey = ApiKey, channel = Channel, text = Text}.
6> pechkin:send(Message).

Roadmap

• http API
• balancer (if there are many pechkins in the cluster)
