Installing

Cargo

cargo install despell

Note Make sure that $HOME/.cargo/bin is in your PATH environment variable

Requirements

despell requires your terminal to use a Nerd Fonts-patched font.

How does it work?

At its core, despell takes a string (process name) as input and returns a string (icon) as output.

Getting started

To use despell in your existing config, replace all occurrences of

#W

with

#(despell #W) #W

in your ~/.tmux.conf.

If you don't have a ~/.tmux.conf yet, have a look at the example configs below to get started.

Example config

You can start using despell by using the example config from the screenshot. Copy of the config below into your own ~/.tmux.conf to get started.

# Colors
tmux_active_fg=#a6accd
tmux_active_bg=#414863
tmux_inactive_fg=default
tmux_statusbar_bg=#232235

# Window status separator
set-window-option -g window-status-separator ''

# Status bar
set-option -g status-style bg=$tmux_statusbar_bg
set-option -g status-left ""
set-option -g status-right ""

# Justify status bar
set -g status-justify centre

# Active
set-window-option -g window-status-current-format "\
#[bg=$tmux_active_bg] #(despell -c #W)\
#[fg=$tmux_active_fg bg=$tmux_active_bg] #W "

# Inactive
set-window-option -g window-status-format "\
#[fg=$tmux_inactive_fg,bg=$tmux_statusbar_bg] #(despell -c #W)\
#[fg=$tmux_inactive_fg,dim bg=$tmux_statusbar_bg] #W "

Settings

Center alignment

To center the status line instead of left aligned (default), add the following command to your ~/.tmux.conf:

# Set alignment
set -g status-justify centre

Update frequency

To configure how often tmux refreshes its status line, add the following command to your ~/.tmux.conf:

# Update the status line every X seconds
set -g status-interval 5

Per-icon colors

To let despell set the icon color and override your theme settings, run despell with the -c or --color flag:

#(despell -c #W)

Emojis

To use emojis instead of Nerd Fonts, run despell with the -e or --emoji flag:

#(despell -e #W)

Overriding and adding icons

To override any of the default mappings, run despell with the -u or --custom flag. Place a config.toml in ~/.config/despell/config.toml with your custom mappings.

All fields are optional, so if you don't use emojis, you can safely omit the fields from the TOML.

[default]
nerdfont = "β—’"
color = "none"
emoji = "🐠"

[icons.command1]
nerdfont = "β—‡"
color = "blue"
emoji = "🌐"

[icons.command2]
nerdfont = "❀"
color = "magenta"
emoji = "πŸ’™"
