在 Ubuntu 上为 Alacritty 设置 Nerd Fonts

Source: Dev.to

安装 Nerd Font

# Create fonts directory
mkdir -p ~/.local/share/fonts

# Download JetBrainsMono Nerd Font (or any you prefer)
wget https://github.com/ryanoasis/nerd-fonts/releases/latest/download/JetBrainsMono.zip

# Unzip
unzip JetBrainsMono.zip -d ~/.local/share/fonts/JetBrainsMono

# Refresh font cache
fc-cache -fv

# Verify installation
fc-list | grep -i "JetBrains"

你应该会看到类似以下的输出：

~/.local/share/fonts/JetBrainsMono/JetBrainsMonoNerdFont-Regular.ttf: JetBrainsMono Nerd Font:style=Regular
~/.local/share/fonts/JetBrainsMono/JetBrainsMonoNerdFontMono-Regular.ttf: JetBrainsMono Nerd Font Mono:style=Regular

注意: 在终端配置中使用 JetBrainsMono Nerd Font（或 JetBrainsMono Nerd Font Mono）。

配置 Alacritty

# Create config directory if it doesn't exist
mkdir -p ~/.config/alacritty

# Open the config file
nano ~/.config/alacritty/alacritty.toml

在 alacritty.toml 中添加以下内容：

[font]
size = 13.0

[font.normal]
family = "JetBrainsMono Nerd Font"
style = "Regular"

[font.bold]
family = "JetBrainsMono Nerd Font"
style = "Bold"

[font.italic]
family = "JetBrainsMono Nerd Font"
style = "Italic"

[font.bold_italic]
family = "JetBrainsMono Nerd Font"
style = "Bold Italic"

保存文件（Ctrl+O → Enter → Ctrl+X）。

安装 Alacritty（Ubuntu 22.04+）

# Via APT
sudo apt install alacritty

# Or via Snap
sudo snap install alacritty --classic

应用更改

关闭所有打开的 Alacritty 窗口并重新打开，或手动启动：

alacritty &

现在，Starship、lsd、eza 或 Neovim 等工具中的图标应该能够完整显示。 🎉
