The i3wm Theme Manager was created to facilitate the management of i3 Window Manager configuration files, both in terms of aesthetics and functionality. With this tool, you can easily change themes, including settings related to other monitors and their sizes.

The i3wm Theme Manager has the following dependencies:

• i3-gaps: A fork of the i3 window manager with support for adjustable gaps between windows.
• Nitrogen: A utility for setting and managing desktop wallpapers, providing an easy way to customize your desktop background.
• Zenity: A tool that enables the creation of simple graphical interfaces in command-line scripts, making user interaction more convenient.
• Picom: An X11 window compositor utility that enhances the user experience with visual effects, transparency, and shadowing.

To install the dependencies on Debian-based systems, run the following command:

sudo apt-get update && sudo apt-get install i3-gaps nitrogen zenity picom

For Arch-based systems, use the following command:

sudo pacman -Syu i3-gaps nitrogen zenity picom

On Fedora, execute the following command:

sudo dnf install i3-gaps nitrogen zenity picom

To install the i3wm Theme Manager, follow the instructions below:

1. Clone the repository:

git clone https://github.com/KennysSparda/i3-theme-manager.git ~/.config/i3-theme-manager

2. Save your current i3 configuration, as the i3wm Theme Manager will overwrite the ~/.config/i3/config file with the corresponding file for the selected theme.

3. Run the program for the first time:

~/.config/i3-theme-manager/i3-theme-manager.sh

4. Add the following line to your .bashrc or .zshrc file to allow running the script directly from the terminal:

To create a new theme, follow these steps:

1. Create new directory on ~/.config/i3-theme-manager/themes/my-new-theme

mkdir -p ~/.config/i3-theme-manager/themes/my-new-theme

2. Place an image file with name "image" in the ~/.config/i3-theme-manager/themes/my-new-theme directory. This image will be associated with the new theme.

3. Add new entry on zenity menu for my-new-theme in ~/.config/i3-theme-manager/i3-theme-manager.sh file:

# [...]
menu() {
  options=("red" "blue" "green" "purple" "my-new-theme" "Exit")
  theme=$(zenity --list --height="300" --title="Change theme" --column="Themes" "${options[@]}")

  case $theme in
    red|blue|green|purple|my-new-theme)
# [...]

4. In the configuration file ~/.config/i3-theme-manager/apply-color.sh create new case for your favorite color palette, and add colors in hexadecimal format, like this:

  my-new-theme)
    primarycolor="#ffff00"
    secundarycolor="#333333"
    tertiarycolor="#000000"
    ;;
