序言

前段时间在 B 站看到了Windows 10 上 PowerShell 使用 oh-my-posh 美化的相关视频， 我也在自己的办公电脑上使用美化后的终端一段时间，还是比较喜欢的，现在在自己的电脑上进行终端美化工程。

美化过程

Windows Terminal

美化的第一步需要安装 Windows Terminal，可以直接访问这个链接进行下载安装 https://github.com/microsoft/terminal/releases ，或者从 Windows 应用商店里面安装，安装完成后再打开会是这样的界面。

PowerShell 7

直接从这个链接下载安装包 ： https://github.com/PowerShell/PowerShell/releases ，Windows 自带的版本不行，换成 PowerShell 7 使用起来更爽，我安装的是预览版本。安装完毕打开之后如下图：

PSReadLine

这里安装 PSReadLine 模块，需要 PowerShell 安装完成 。

以管理员权限启动 PowerShell 后直接执行如下命令，需要下载模块，没有进度提示需静静等待：

Install-Module PSReadLine -Scope AllUsers -AllowPrerelease -Force -Verbose

最后选择 Y (Yes) 确认安装。

oh-my-posh

这一步安装 oh-my-posh 模块， 和 Linux 里面的 oh-my-zsh 类似，接着上一步直接执行下面的命令：

Install-Module oh-my-posh -Scope AllUsers -AllowPrerelease -Verbose

同样选择 Y 进行安装。

posh-git

这里安装 posh-git，会使git 在终端中更好用，接着执行命令：

Install-Module posh-git -Scope AllUsers -AllowPrerelease -Verbose

同样选择 Y 继续安装。

Fonts

安装完模块之后，这一步安装字体，因为Windows自带的字体是不包含某些符号，如果字体用的不好的话，显示出来的终端还不如默认的。

在这里安装 Nerd Font 字体，我经常使用的是 FiraCode Nerd Font Mono 字体，因为用习惯了，这个字体的链接是 https://github.com/ryanoasis/nerd-fonts/releases/download/v2.1.0/FiraCode.zip， 其他字体可通过这个链接下载： https://github.com/ryanoasis/nerd-fonts/releases/tag/v2.1.0 。

解压之后选择一个安装，需要注意一下，字体名称自己需要记录一下，方便下一步使用，字体名称如下：

Terminal Setting

在美化 Terminal 之前， 先设置 Terminal 一下， 在 Terminal 中集成 PowerShell ， 以后的主力终端就是 PowerShell 了 。我的配置如下：

// To view the default settings, hold "alt" while clicking on the "Settings" button.
// For documentation on these settings, see: https://aka.ms/terminal-documentation
{

  ]
}

将 PowerShell 的路径修改为自己的实际路径就 OK 了，那么以后打开 Windows Terminal 会默认打开 PowerShell ， 如图：

美化过程

安装完上面的3个模块后，就可以设置界面了，oh-my-posh 中附带了几个主题， 可以使用 Get-PoshThemes 预览主题，然后选择自己喜欢的。

但是，自带的几个主题对我来说稍稍有点儿缺陷，因此我自己修改了一点，适合自己才是最好的。废话先不多说，看一下美化过程。

首先设置 PowerShell 的 Profile 文件， 在 PowerShell 中执行命令 ： notepad.exe $Profile ， 将下面的内容输入到文件中并保存：

# 引入 posh-git
Import-Module posh-git

# 引入 oh-my-posh
Import-Module oh-my-posh

# 设置 PowerShell 主题
Set-PoshPrompt Paradox-plus

# 设置显示命令历史
set-psreadlineoption -predictionsource history

# 设置 Tab 为菜单补全
Set-PSReadLineKeyHandler -Key "Tab" -Function MenuComplete

# 设置 Ctrl+d 为退出 PowerShell
Set-PSReadlineKeyHandler -Key "Ctrl+d" -Function ViExit

# 设置 Ctrl+z 为撤销
Set-PSReadLineKeyHandler -Key "Ctrl+z" -Function Undo

# 设置向上键为后向搜索历史记录
Set-PSReadLineKeyHandler -Key UpArrow -Function HistorySearchBackward

# 设置向下键为前向搜索历史纪录
Set-PSReadLineKeyHandler -Key DownArrow -Function HistorySearchForward

# Python 直接执行
$env:PATHEXT += ";.py"

Set-Alias -Name ls -Value Get-ChildItem

这里的主题被我设置为 Paradox-plus ，实际上并不存在这个主题，我只是修改了 Paradox 主题，使其更适合于我。

到这个目录下，C:\Program Files\PowerShell\Modules\oh-my-posh\3.130.0\themes 这里存放的是 oh-my-posh 的主题文件，这里的版本号可能不一样，只需要找到 oh-my-posh 目录就可以找到 themes 目录 ， 直接修改或者复制后重命名为 paradox-plus.omp.json ，将里面的内容替换为如下内容：

          }
        },
        {
          "type": "time",
          "style": "plain",
          "foreground": "#007ACC",
          "properties": {
            "time_format": "15:04:05"
          }
        }
      ]
    },
    {
      "type": "newline"
    },
    {
      "type": "prompt",
      "alignment": "left",
      "segments": [
        {
          "type": "text",

          "properties": {
            "prefix": "",
            "text": "\u276F"
          }
        }
      ]
    }
  ],
  "final_space": false
}

到此就完成了，看一下效果：

2021-04-15更新：

由于我经常使用 Anaconda 集成 Python ，所以今天才发现 PowerShell 中无法激活 Python 的虚拟环境，解决方法如下：

直接在 PowerShell 中执行 conda init powershell ，然后重启终端。效果如下：

现在可以正常切换 conda 的虚拟环境了，但是我还有一个需求，就是希望可以一直显示当前的 Python 环境，毕竟这个主题默认情况下只在有Python源码的目录里面显示后面的python信息，下面我把我的主题再次更新了一下，以方便一直显示 Python 信息：

    }

}

Python 段的设置可以参考官方文档 https://ohmyposh.dev/docs/python ，我把 display_mode 设置为 always 就是希望一直显示这个 Python 信息段，但是有些不足的是只能在非家目录里面显示，如图：

另外，这个主题颜色比较刺眼，文字都是绿色的，给一个我比较喜欢的暗色调的配色：

  "brightWhite": "#ddccbb",
  "background": "#1c1c1c",
  "foreground": "#ddeedd",
  "selectionBackground": "#4d4d4d",
  "cursorColor": "#e2bbef"
}

效果如下图，同时也可以通过 https://windowsterminalthemes.dev/ 网站自己选择适合自己的配色。

这两种配色我都挺喜欢的，都在 Terminal Setting 中保存着。

结语

本次终端就美化成这样，后面可能会有细微的调整，还是那句话，适合自己的才是最好用的。
