nixos美化shell及常用软件安装

最近回到家，又开始折腾nixos了，当前主题

fish+starship 安装及美化 @

最近把shell从zsh+p10k的模式切换成了fish+starship，发现fish的性能要好很多，同时starship的配置也很方便，配置如下，很简单。

{ config, pkgs, ... }:

{
  home.packages = [ pkgs.starship ];

  # 这里是starship的主题配置文件，网上可以随便找一个
  home.file.".config/starship.toml".source = ./starship.toml;

  programs.fish = {
    enable = true;

    # 这里是删除fish的欢迎信息
    interactiveShellInit = ''
      set fish_greeting
    '';
  };

  programs.starship = {
    enable = true;
    package = pkgs.starship;
  };
}

overview wallpaper配置 @

其实之前壁纸设置好之后，但在壁纸的缩略图中，背景还是灰色，很难看。其实需要将工作区的壁纸也同时配置在overview才行。

首先在niri-config.kdl配置文件添加这个layer-rule的设置

// Set the overview wallpaper on the backdrop.
layer-rule {
  match namespace="^noctalia-overview.*"
  place-within-backdrop true
}

然后在noctalia的配置里开启overview壁纸

wallpaper = {
    enabled = true;
    overviewEnabled = true;     # 这里开启
    useSolidColor = false;
    directory = "${config.home.homeDirectory}/.config/noctalia/wallpapers";
    viewMode = "crop";
    wallpaperChangeMode = "random";
};

安装chrome和splayer @

chrome浏览器当然不用说，现在基本都用这个。splayer则是一个网易云的播放器，UI做的挺好看的，比较推荐, 安装也很简单。

home.packages = with pkgs; [
    google-chrome
    splayer
  ];

图标主题更换 @

我认为noctalia的默认主题有点丑，并且小部分应用是确实图标的，所以必须安装一个图标主题。我选择的是WhiteSur-dark。

按照以下配置即可，需要适配gtk2/gtk3/gtk4各种应用的图标主题。

{ config, pkgs, lib, ... }:

let
  iconThemeName = "WhiteSur-dark";
in
{
  gtk = {
    enable = true;
    iconTheme = {
      name = iconThemeName;
      package = pkgs.whitesur-icon-theme;
    };
  };

  gtk.gtk3 = {
    enable = lib.mkDefault true;
  };

  gtk.gtk4 = {
    enable = lib.mkDefault true;
  };

  home.sessionVariables = {
    XDG_ICON_THEME = iconThemeName;
    QT_QPA_PLATFORMTHEME = "gtk3";
    QS_ICON_THEME = iconThemeName;
  };

  home.packages = with pkgs; [
    whitesur-icon-theme
    hicolor-icon-theme
  ];
}

在hosts/default/defualt.nix，也就是全局环境变量，也需要配置, 否则可能不生效

environment.sessionVariables = {
    QS_ICON_THEME = "WhiteSur-dark";
};

hyprlock锁屏 @

hyprlock是hyprland下的一个锁屏软件，但是niri也能用，新建一个hyprlock.nix用于管理hyprlock配置，然后在你的home.nix里import它。

具体配置如下

{pkgs, ...}: {
  home.packages = with pkgs; [
    hyprlock
  ];

  programs.hyprlock.enable = true;

  home.file."/.config/hypr/hyprlock.conf".source = ./hyprlock.conf;
}

hyprlock.conf的内容如下, 这份配置是我在github抄的配置，如有侵权，请联系我删除。

fuzzel启动器 @

fuzzel是一个启动器，用来搜索系统中的应用程序，比较简洁，配置如下

{ ... }:
{
  programs.fuzzel = {
    enable = true;
    settings = {
      main = {
        font = "JetBrainsMono Nerd Font:weight=bold:size=14";
        line-height = 25;
        fields = "name,generic,comment,categories,filename,keywords";
        terminal = "kitty";
        prompt = "' ➜  '";
        icon-theme = "Papirus-Dark";
        layer = "top";
        lines = 10;
        width = 35;
        horizontal-pad = 25;
        inner-pad = 5;
      };
      colors = {
        background = "1e1e2ecc";
        text = "cdd6f4ff";
        match = "f38ba8ff";
        selection = "b4befeaa";
        selection-match = "f38ba8ff";
        selection-text = "cdd6f4ff";
        border = "b4befeff";
      };
      border = {
        radius = 15;
        width = 3;
      };
    };
  };
}

由于目前的flake项目已经相对完善了，于是我可以把github的链接放出来，给大家参考，因为我也是参考了很多别人的配置写的，希望nixos社区越来越好。我的nixos-config
