Foreglow Theme for Tmux

A tmux theme based on the Foreglow color palette.

Installation

The default variant is Foreglow (dark). See Choosing a variant below to use Afterglow, Alpenglow, or Airglow instead.

Option 1: Tmux Plugin Manager (TPM)

Add this to your .tmux.conf:

set -g @plugin 'foreglow/tmux'

Then reload tmux and install:

prefix + I

Option 2: Manual Installation

Clone this repository or copy the theme file:

git clone https://github.com/foreglow/tmux ~/foreglow-tmux

Add this to your .tmux.conf:

run-shell ~/foreglow-tmux/foreglow.tmux

Then reload tmux:

tmux source ~/.tmux.conf

The .tmux files are executable shell scripts that apply the theme via tmux set-option, so they must be run with run/run-shell (not source/source-file).

Choosing a variant

Each variant is its own file: foreglow.tmux (dark, default), afterglow.tmux (light), alpenglow.tmux (rubescent), airglow.tmux (auroral).

• Manual installation: swap the filename in the run-shell line above, e.g. run-shell ~/foreglow-tmux/afterglow.tmux.

• TPM installation: TPM runs every .tmux file in the plugin, and foreglow.tmux always applies last, so TPM alone always gives you the dark default. To use another variant with TPM, source it directly from TPM's plugin directory in a line placed after TPM's own initializer line (the run '~/.tmux/plugins/tpm/tpm' line, normally at the very bottom of .tmux.conf) so it overrides the default that TPM just applied:

  set -g @plugin 'foreglow/tmux'
  
  run '~/.tmux/plugins/tpm/tpm'          # keep this at the bottom, as usual
  run-shell '~/.tmux/plugins/tmux/afterglow.tmux'   # then override with your variant

Switching variants on the fly

tmux-set applies a variant to your current session immediately, no config edit or reload needed. Run it from any pane inside tmux:

./tmux-set afterglow      # or: ./tmux-set afterglow.tmux

It accepts any of foreglow, afterglow, alpenglow, airglow (with or without the .tmux suffix), and errors out with the list of valid names if you pass something else. Run it with no arguments to just see that list.

Usage

Reload theme

tmux source ~/.tmux.conf

Status bar positioning

To move the status bar to the top, add this to your .tmux.conf before sourcing the theme:

set -g status-position top

Requirements

• 256 color terminal support

Troubleshooting

Make sure your terminal supports 256 colors:

echo $TERM

It should show something like xterm-256color or screen-256color.
