Change terminal colors on the fly

dynamic-colors

Utility for changing terminal colors on the fly.

Fork of abandoned sos4nt/dynamic-colors.

Pre-requisites

Your terminal must support the appropriate OSC escape sequences. xterm and urxvt (rxvt-unicode) work, whereas e.g. Terminal.app or iTerm won't recognize these sequences.

Make sure dynamicColors is enabled in ~/.Xresources

xterm*dynamicColors: true
urxvt*dynamicColors: on

Setup

1. Add dynamic-colors file to your PATH.

2. Put your colorschemes in the configuration directory (commonly ~/.config/dynamic-colors/colorschemes), or set $DYNAMIC_COLORS_COLORSCHEMES environment variable to desired path.

3. To enable auto-completion, add this into your shell configuration file:

   source $HOME/.dynamic-colors/completions/dynamic-colors.(zsh|bash)

Usage

List available color schemes:

dynamic-colors list

Switch to a color scheme:

dynamic-colors switch solarized-dark

Reload last color scheme:

dynamic-colors init

Key binding example for urxvt

Save this to ~/.urxvt/ext/dynamic-colors:

sub on_action {
  my ($self, $cmd) = @_;
  if ($cmd eq "cycle") {
    my $output = `dynamic-colors cycle`;
    $self->cmd_parse($output);
  }
}

And bind the key in ~/.Xresources:

urxvt*perl-ext-common: dynamic-colors
urxvt*keysym.F12: dynamic-colors:cycle

Now you can cycle through all color schemes using F12 without closing running console applications.
