Tmux Configuration

Tmux configuration, that supercharges your tmux and builds cozy and cool terminal environment. This repository is custom version from samoshkin/tmux-config, thanks to him (https://github.com/samoshkin/tmux-config)

Features

• "C-a" prefix instead of "C-b" (screen like)
• support for nested tmux sessions
• scroll and copy mode improvements
• supercharged status line
• renew tmux and shell environment (SSH_AUTH_SOCK, DISPLAY, SSH_TTY) when reattaching back to old session
• prompt to rename window right after it's created
• newly created windows and panes retain current working directory
• monitor windows for activity/silence
• highlight focused pane
• merge current session with existing one (move all windows)
• configurable visual theme/colors, with some elements borrowed from Powerline
• integration with 3rd party plugins: tmux-sidebar, tmux-copycat, tmux-open, tmux-plugin-sysstat

Status line widgets:

• CPU, memory usage, system load average metrics
• username and hostname, current date time
• visual indicator when you press prefix
• visual indicator when you're in Copy mode
• visual indicator when pane is zoomed
• online/offline visual indicator

Installation

Prerequisites:

• tmux >= "v2.4"
• OSX, Linux (tested on Ubuntu 14 and CentOS7), FreeBSD (tested on 11.1)

To install tmux-config:

$ git clone https://github.com/sasoe-git/tmux-custom.git
$ ./tmux-config/install.sh

install.sh script does following:

• copies files to ~/.tmux directory
• symlink tmux config file at ~/.tmux.conf, existing ~/.tmux.conf will be backed up
• Tmux Plugin Manager will be installed at default location ~/.tmux/plugins/tpm, unless already presemt
• required tmux plugins will be installed

Finally, you can start new tmux session:

$ tmux new

Key bindings

tmux key	Description	iTerm2 key
C-a	Default prefix, used instead of "C-b". Same prefix is used in screen program, and it's easy to type. The only drawback of "C-a" is that underlying shell does not receive the keystroke to move to the beginning of the line.	-
