Powershell美化

Powershell 是微软推出用于取代CMD的一款命令行工具。虽然使用上非常的强大，但是其外观一如以往的CMD一样，非常的丑。作为“颜值就是正义”的信徒，就想着动手改造一下，以此文来做个记录。

最终效果展示:

环境配置

Windows10
Powershell 5.1

字体

下载字体Microsoft YaHei Mono

Microsoft YaHei Mono = YaHei + Consolas

将PowerShell的字体改为这个

配色

Microsoft出过一个用于Powershell的配色工具ColorTool

下载解压后，在解压后的文件夹里打开Powershell，运行

1	colortool -b campbell

Powershell就应用了campbell schemes

该工具默认提供了以下Schemes：

campbell : The new default color scheme for Windows Console
campbell-legacy : The first iteration of the campbell scheme
cmd-legacy : The legacy defaults of the Windows Console
OneHalfDark : A dark vim-airline theme by Son A. Pham
OneHalfLight : A light vim-airline theme by Son A. Pham
solarized_dark : The dark version of a popular color scheme by Ethan Schoonover
solarized_light : The light version of a popular color scheme by Ethan Schoonover
deuteranopia : A color scheme targeted towards making red and green clearer to users with red green colorblindness, and deuteranopia.

如果想看看更多的Schemes，可以到iTerm2-Color-Schemes上下载，只要把下载的itermcolors格式文件放到colortool下的schemes文件夹下即可。

Powershell主题设置

如果有用过oh-my-zsh的，肯定对上面各种酷炫的theme很有印象。然而在Powershell中，用Powershell configuration就可以非常简单的实现oh-my-zsh里的大部分theme。

这里以oh-my-zsh中的ys为例

首先,打开Powershell,并输入

1	notepad $((Split-Path $profile -Parent) + “/profile.ps1”)

如果不存在profile默认会创建，接着在打开的记事本里输入

function prompt {

    $path = Split-Path -leaf -path (Get-Location)
    $Date = Get-Date

    Write-Host
    Write-Host "# " -NoNewline -ForegroundColor Blue
    Write-Host $env:USERNAME -NoNewline -ForegroundColor Cyan
    Write-Host " in " -NoNewline
    Write-Host $path -NoNewline -ForegroundColor Green
    Write-Host " "$Date
    Write-Host ">" -NoNewline -ForegroundColor Magenta

    return " "
}

保存并重新打开Powershell后，就能发现样式就变得和ys一样了。
如果你还想显示Git status信息的话，就需要使用Posh-git,其Github主页上有它的安装方式。

Prerequisites
Before installing posh-git make sure the following prerequisites have been met.

Windows PowerShell 5.x or PowerShell Core 6.0.
You can get PowerShell Core 6.0 for Windows, Linux or macOS from [here][pscore-install].
Check your PowerShell version by executing $PSVersionTable.PSVersion.

On Windows, script execution policy must be set to either RemoteSigned or Unrestricted.
Check the script execution policy setting by executing Get-ExecutionPolicy.
If the policy is not set to one of the two required values, run PowerShell as Administrator and
execute Set-ExecutionPolicy RemoteSigned -Scope CurrentUser -Confirm.

Git must be installed and available via the PATH environment variable.
Check that git is accessible from PowerShell by executing git --version from PowerShell.
If git is not recognized as the name of a command, verify that you have Git installed.
If not, install Git from https://git-scm.com.
If you have Git installed, make sure the path to git is in your PATH environment variable.

Installing posh-git via PowerShellGet
posh-git is available on the [PowerShell Gallery][psgallery-v1] and can be installed using the PowerShellGet module.
Start either Windows PowerShell 5.x or PowerShell Core 6.x (pwsh).
Execute one of the following two commands from an elevated PowerShell prompt,
depending on whether (A) you’ve never installed posh-git, or (B) you’ve already installed a previous version:
1
2
3
4
5
6
7
# (A) You’ve never installed posh-git from the PowerShell Gallery
#
# NOTE: If asked to trust packages from the PowerShell Gallery, answer yes to continue installation of posh-git
# NOTE: If the AllowPrerelease parameter is not recognized, update your version of PowerShellGet to >= 1.6 e.g.
#       Install-Module PowerShellGet -Scope CurrentUser -Force -AllowClobber

PowerShellGet\Install-Module posh-git -Scope CurrentUser -AllowPrerelease -Force
OR
1
2
# (B) You’ve already installed a previous version of posh-git from the PowerShell Gallery
PowerShellGet\Update-Module posh-git

posh-git安装好后，将之前的profile.ps1文件,修改成：


Import-Module posh-git
function prompt {

    $path = Split-Path -leaf -path (Get-Location)
    $Date = Get-Date
    $gitStatus = Write-VcsStatus

    Write-Host
    Write-Host "# " -NoNewline -ForegroundColor Blue
    Write-Host $env:USERNAME -NoNewline -ForegroundColor Cyan
    Write-Host " in " -NoNewline
    Write-Host $path -NoNewline -ForegroundColor Green
    $realLASTEXITCODE = $LASTEXITCODE
    Write-Host $gitStatus -NoNewline
    $global:LASTEXITCODE = $realLASTEXITCODE
    Write-Host " "$Date
    Write-Host ">" -NoNewline -ForegroundColor Magenta

    return " "
}

以上，本次的美化教程到此结束。
