Installing tmux-256color for macOS

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):

Examples of using advisory locking with golang.org/x/sys/unix
// These funcitons ought to come with a huge warning. Using them without
// understanding the differences between blocking and non-blocking, or
// between exclusive and shared access, and when to use them will cause
// problems that do not necessarily manifest right away, but rather
// fester in your program and rear their ugly head in the middle of the
// night when you're sleeping.
//
// If you use advisory file locking, *always* use Shared locking every
// single time you read the file, and *always* use Exclusive locking every
// single time you write the file. Period. There are no exceptions. Heed

Blocked SSH port, GitHub workaround
# Put in your ~/.ssh/config
### Problem
#
# You are on a public WiFi network that blocks SSH ports but you don't want to switch
# to pushing your Github changes to GH remotes via HTTPS nor do you want to change the
# remote hostname in all your repos.
Host github.com
Hostname ssh.github.com
