git init
git add README.md
git commit -m "first commit"
git branch -M main
git remote add origin https://github.com/kaiyu-tech/MyFirstDiscorbBot.git
git push -u origin main
Gemfile
# frozen_string_literal: true

source "https://rubygems.org"

git_source(:github) { |repo_name| "https://github.com/#{repo_name}" }

ruby "~> 3.0"

gem "discorb"

bundle install

bundle lock --add-platform x86_64-linux
main.rb
require "discorb"

client = Discorb::Client.new

client.once :ready do
  puts "Logged in as #{client.user}"
end

client.on :message do |message|
  next if message.author.bot?
  next unless message.content == "/ping"

  message.channel.post("pong!")
end

client.run(ENV["DISCORD_BOT_TOKEN"])
Procfile
worker: bundle exec ruby main.rb

Discord Developer Portal でBot Acountを作る
