Server.new

Examples#

Connect a Server client to an existing endpoint and close it without stopping the daemon. The outer Server.start block owns the private demonstration server. Use Ruby 4.0.7, Bundler, Git and tmux 3.3a or newer on Unix, with /bin/cat and /bin/sh available. In an empty directory, fetch the documented library revision:

$ git clone https://github.com/libtmux/libtmux-ruby.git libtmux-source && \
  git -C libtmux-source checkout c8b839595d5a30e271e3f9be0d0fe811ddb11b7e

Save this dependency file as Gemfile:

source "https://rubygems.org"

gem "libtmux", path: "libtmux-source/gems/libtmux"

Save this complete program as server.rb. Its Server.start block owns a private tmux server and stops it on exit, including after an error. View source

# frozen_string_literal: true

begin
  # docs:begin main
  require "libtmux"

  LibTmux::Server.start do |owner|
    owner.new_session(name: "work", command: ["/bin/cat"])
    server = LibTmux::Server.new(endpoint: owner.endpoint)
    begin
      puts "connected sessions: #{server.list_sessions.length}"
    ensure
      server.close
    end
    puts "sessions after client close: #{owner.list_sessions.length}"
  end
  # docs:end main
rescue StandardError => error
  warn "#{error.class}: #{error.message}"
  exit 1
end

Install the runtime dependencies and run the saved program. An operation or cleanup error makes it exit unsuccessfully:

$ bundle config set --local path vendor/bundle && \
  bundle install --jobs 2 && \
  bundle exec ruby server.rb

Expected output:

connected sessions: 1
sessions after client close: 1
