Telegram Bot API library written in Crystal. Meant to be a simple, easy to use, and fast library for writing Telegram bots.

Add this to your application's shard.yml:

dependencies:
  tourmaline:
    github: protoncr/tourmaline
    branch: master

API documentation is also available here.

Examples are available in the examples folder.

Just for README purposes though, let's look at the echo bot example:

require "tourmaline"

client = Tourmaline::Client.new(ENV["BOT_TOKEN"])

echo_handler = Tourmaline::CommandHandler.new("echo") do |ctx|
  text = ctx.text.to_s
  ctx.reply(text) unless text.empty?
end

client.register(echo_handler)

client.poll
