Installing tmux-256color for macOS

macOS 10.15.5
tmux 3.1b

macOS has ncurses version 5.7 which does not ship the terminfo description for tmux. There're two ways that can help you to solve this problem.

The Fast Blazing Solution

Instead of tmux-256color, use screen-256color which comes with system. Place this command into ~/.tmux.conf or ~/.config/tmux/tmux.conf(for version 3.1 and later):

Add the following to application.rb:

$icallbacks = []
$icallbacks.define_singleton_method(:print) do
  puts sort_by { |(a, b)| -b }.map { |(a, b)| "#{b}\t\t#{a}" }.join("\n")
end

ActiveSupport::Notifications.subscribe("load_config_initializer.railties") do |event|
 $icallbacks &lt;&lt; [event.payload[:initializer], event.duration]

For years, people have been using jemalloc with ruby. There were various benchmarks and discussions. Legend had it that Jemalloc 5 didn't work as well as Jemalloc 3.

Then, one day, hope appeared on the horizon. @wjordan offered a config for Jemalloc 5.
