Server.new_session

Examples#

Start a private server and create a session. Request a creation receipt to read the session, window, and pane IDs returned by that creation command. Use Ruby 4.0.7, Bundler, Git and tmux 3.2a 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 dcc9f8b5a6970144a9e7d80cd5f381d8f6198372

Save this dependency file as Gemfile:

source "https://rubygems.org"

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

Save this complete program as new_session.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

require "libtmux"

begin
  LibTmux::Server.start do |server|
    created = server.new_session(
      name: "work", window_name: "main", command: ["/bin/cat"], receipt: true
    )
    puts "session: #{created.entity.id}"
    puts "window: #{created.window.id}"
    puts "pane: #{created.pane.id}"
  end
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 new_session.rb

Expected output:

session: $0
window: @0
pane: %0
