Behavior contract: Options and hooks.
Examples#
Set and read a session option, convert its value to an Integer, and attach a hook command to the same session. 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 d8ce4bbee0ca7748a81929f81f7d8d07f8c51267Save this dependency file as Gemfile:
source "https://rubygems.org"gem "libtmux", path: "libtmux-source/gems/libtmux"Save this complete program as options.rb. Its Server.start block owns a private tmux server and stops it on exit, including after an error. View source
