def run_group: ( ::Array[::Array[::String]], ?input: ::String, ?timeout: ::Numeric, ?cancel: untyped ) -> ::LibTmux::GroupResult

Description#

Behavior contract: Command groups.

Examples#

Submit an ordered group whose second command fails. The group reports unknown per-step outcomes, keeps the first command's effect and never runs the third. 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:

Terminal window
$ git clone https://github.com/libtmux/libtmux-ruby.git libtmux-source && \
git -C libtmux-source checkout d8ce4bbee0ca7748a81929f81f7d8d07f8c51267

Save this dependency file as Gemfile:

source "https://rubygems.org"
gem "libtmux", path: "libtmux-source/gems/libtmux"

Save this complete program as run_group.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 |server|
server.new_session(name: "work", command: ["/bin/cat"])
group = server.run_group([
["set-option", "-g", "@before", "kept"],
["select-pane", "-t", "%4294967294"],
["set-option", "-g", "@after", "never run"]
])
puts "success: #{group.success?}"
puts "steps: #{group.steps.map { |step| step.fetch(:outcome) }.join(', ')}"
puts "@before: #{server.options(scope: :session).get('@before').as(:string)}"
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:

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

Expected output:

success: false
steps: unknown, unknown, unknown
@before: kept
