## Tmux
Tmux is a terminal multiplexer for managing multiple virtual terminals and SSH connections.
### Install
Create a `~/.tmux/plugins` directory and clone the tmux plugin manager and dracula theme repositories.
``` bash
mkdir -p ~/.tmux/plugins
cd ~/.tmux/plugins
# Tmux Plugin Manager
git clone https://github.com/tmux-plugins/tpm
# Tmux Dracula Theme
git clone https://github.com/dracula/tmux
```
### Configure
Configure `~/.tmux.conf`.
```
# List of plugins
set -g @plugin 'tmux-plugins/tpm'
set -g @plugin 'tmux-plugins/tmux-sensible'

# THEME
set -g @plugin 'dracula/tmux'  

# KEYBINDINGS
unbind C-b
set -g prefix C-j

bind C-n select-pane -D
bind C-p select-pane -U
bind C-f select-pane -R
bind C-b select-pane -L

bind h split-window -h
bind v split-window -v

# TERMINAL
set -g default-terminal "rxvt-256color"

# Initialize TMUX plugin manager (keep this line at the very bottom of tmux.conf)
run -b '~/.tmux/plugins/tpm/tpm'
```
Create a bash function for initializing terminals and SSH connections in Tmux.
``` bash
#!/bin/bash
# TMUX SETUP FUNCTION
tmux_new() {
    SERVER=/tmp/tmux-1000/yve
    SESSION=slack
    # tmux init
    tmux -S $SERVER new -s $SESSION -d
    tmux -S $SERVER rename-window -t $SESSION ware
    # emacs window
    tmux -S $SERVER new-window -t $SESSION
    tmux -S $SERVER  rename-window -t $SESSION emacs
    tmux -S $SERVER send-keys -t $SESSION 'emacsclient -nw --socket-name /home/jc/.emacs.d/server/server' C-m
   # doom window
    tmux -S $SERVER new-window -t $SESSION
    tmux -S $SERVER rename-window -t $SESSION doom
    tmux -S $SERVER send-keys -t $SESSION 'doom-run' C-m
    # kodaiji window x2 panes
    tmux -S $SERVER new-window -t $SESSION
    tmux -S $SERVER rename-window -t $SESSION kodaiji
    tmux -S $SERVER send-keys -t $SESSION 'ssh kodaiji' C-m
    tmux -S $SERVER split-window -h -t $SESSION
    tmux -S $SERVER send-keys -t $SESSION 'ssh kodaiji' C-m
    # kenninji
    tmux -S $SERVER new-window -t $SESSION
    tmux -S $SERVER rename-window -t $SESSION kenninji
    tmux -S $SERVER send-keys -t $SESSION 'ssh kenninji' C-m
    # saiji
    tmux -S $SERVER new-window -t $SESSION
    tmux -S $SERVER rename-window -t $SESSION saiji
    tmux -S $SERVER send-keys -t $SESSION 'ssh saiji' C-m
    # toji
    tmux -S $SERVER new-window -t $SESSION
    tmux -S $SERVER rename-window -t $SESSION toji
    tmux -S $SERVER send-keys -t $SESSION 'ssh toji' C-m
}
exec tmux_new
```
Now simply source or copy the function to a file and execute from the command line.

====== Emacs ======
===== Doom =====
* [[https://github.com/doomemacs/doomemacs|Github: Doom Emacs]]

I frequently run into problems with Doom Emacs upgrade failures. Most issues can be resolved by simply removing the offending package's local repository and build cache.
<markdown>
``` bash
# Remove the package's repository
rm -rf ~/.emacs.d/.local/straight/repos/<package-name>
# Remove the package's build cache. emacs 28.2 is installed, and the build version number my vary
rm -rf ~/.emacs.d/.local/traight/build-28.2/<package-name>
# Run then Doom Emacs upgrade command
doom upgrade
```

====== Window Manager ======
===== Sway =====
Start sway from lightdm or a shell.
==== Install  ====
**Dependencies:** <code bash> sudo pacman -Su seatd wlroots xcb-util-errors sway</code>
**Optional:** <code bash> sudo pacman -Su  swaybg swayidle swaylock wf-recorder</code>
==== Lightdm Configuration ====
Uncomment ''sessions-directory'' line in ''/etc/lightdm/lightdm.config'' and set user-session to sway.
<code>
sessions-directory=/usr/share/lightdm/sessions:/usr/share/xsessions:/usr/share/wayland-sessions
user-session=sway
</code>

Configure ''/usr/share/wayland-sessions/sway.desktop''.

<code>
[Desktop Entry]

</code>

==== Lightdm Startup ====

Restart services.

<code bash>
systemctl restart lightdm
systemctl enable seatd
systemctl start seatd
</code>

Sway can be started without a desktop manager by configuring the shell initializion file.

<code bash>
