Enables displaying memory information in Tmux status-right and status-left. Configurable percentage and icon display.

Add plugin to the list of TPM plugins in .tmux.conf:

set -g @plugin 'laomafeima/tmux-mem'

Hit prefix + I to fetch the plugin and source it.

If format strings are added to status-right, they should now be visible.

Clone the repo:

$ git clone https://github.com/laomafeima/tmux-mem ~/clone/path

Add this line to the bottom of .tmux.conf:

run-shell ~/clone/path/mem.tmux

Reload TMUX environment:

# type this in terminal
$ tmux source-file ~/.tmux.conf

If format strings are added to status-right, they should now be visible.

ps is required for memory information.

Add any of the supported format strings (see below) to the existing status-right tmux option. Example:

# in .tmux.conf
set -g status-right '#{mem_bg_color} MEM: #{mem_icon} #{mem_percentage}'

This is done by introducing 4 new format strings that can be added to status-right option:

• #{mem_icon} - will display a memory status icon
• #{mem_percentage} - will show memory percentage (averaged across cores)
• #{mem_bg_color} - will change the background color based on the memory percentage
• #{mem_fg_color} - will change the foreground color based on the memory percentage

By default, these icons are displayed:

• low: "="
• medium: "≡"
• high: "≣"

And these colors are used:

• low: #[fg=green] #[bg=green]
• medium: #[fg=yellow] #[bg=yellow]
• high: #[fg=red] #[bg=red]

Note that these colors depend on your terminal / X11 config.

You can change these defaults by adding the following to .tmux.conf:

set -g @mem_low_icon "ᚋ"
set -g @mem_medium_icon "ᚌ"
set -g @mem_high_icon "ᚍ"

set -g @mem_low_fg_color "#[fg=#00ff00]"
set -g @mem_medium_fg_color "#[fg=#ffff00]"
set -g @mem_high_fg_color "#[fg=#ff0000]"

set -g @mem_low_bg_color "#[bg=#00ff00]"
set -g @mem_medium_bg_color "#[bg=#ffff00]"
set -g @mem_high_bg_color "#[bg=#ff0000]"

Don't forget to reload tmux environment ($ tmux source-file ~/.tmux.conf) after you do this.

This project refers to the implementation of tmux-cpu, and I would like to express my gratitude.
Thanks Tmux Plugin Manager great program.
