Flameshot

Flameshot is a powerful screenshot and screenshot annotation tool. Flameshot allows the user to take a screenshot and then draw, write text, blur, crop, and otherwise edit screenshots with ease.

Install

For X11 you can install Flameshot by simply adding it to your configuration file.

❄︎ /etc/nixos/configuration.nix

environment.systemPackages = with pkgs; [
  flameshot
];

Install on Wayland

In order to use Flameshot on Wayland you will need to install Grim and configure Flameshot to use it.

Install Grim

❄︎ /etc/nixos/configuration.nix

environment.systemPackages = with pkgs; [
  grim
];

Configure Flameshot

You may do this through Home Manager, or you may configure it manually in ~/.config/flameshot.

❄︎ /etc/nixos/home.nix

services.flameshot = {
  # Also installs/enables flameshot
  enable = true;
  settings = {
    General = {
      useGrimAdapter = true;
    };
  };
};

Home Manager

You can configure Flameshot settings through Home Manager with the following syntax. Additional settings may be found on the Flameshot github and adapted into Nix. See documented settings in the Home Manager Appendix - services.flameshot.

❄︎ /etc/nixos/home.nix

services.flameshot = {
  enable = true;
  settings = {
    General = {
        
      # More settings may be found on the Flameshot Github

      # Save Path
      savePath = "/mnt/internal/wintermute/Sync/Screenshots";
      # Tray
      disabledTrayIcon = true;
      # Greeting message   
      showStartupLaunchMessage = false;
      # Default file extension for screenshots (.png by default)
      saveAsFileExtension = ".png";
      # Desktop notifications
      showDesktopNotification = true;

      # Color Customization
      uiColor = "#740096";
      contrastUiColor = "#270032";
      drawColor = "#ff0000";

      # For Wayland (Install Grim seperately)
      useGrimAdapter = true;

    };
  };
};
