posh自定义:扩展或修改主题

refs

• 访问速度可能较慢.
  • official build-in themes(list / snapes)
  • theme configuration settings manual

检查预览所有内置的主题

• Themes | Oh My Posh

• 在powershell中输入Get-PoshThemes,posh会将所有主题输出,并且会输出主题配置文件所在目录

  • To change your theme, adjust the init script in C:\Users\cxxu\Documents\PowerShell\Microsoft.PowerShell_profile.ps1.
    Example:
      oh-my-posh init pwsh --config 'C:\Users\cxxu\AppData\Local\Programs\oh-my-posh\themes\jandedobbeleer.omp.json' | Invoke-Expression

主题配置文件所在目录

• 环境变量:$env:POSH_THEMES_PATH

• Themes location: $env:LOCALAPPDATA\Programs\oh-my-posh\themes

基于已有的主题进行更改

• Customize | Oh My Posh

• 先复制一份基本满意的主题

  • 我想使用内置的一个iterm2主题,然而,他的第二个字段颜色过深,我希望将其调整为亮色的
  • 复制一份改主题配置文件
  • 利用编辑器(例如vscode)将副本打开,(您可以参考官网的字段介绍,也可以凭着经验来做一些基本的颜色修改)

• 可以看到,第二个segment背景被我调为浅色,路径部分看起来更加清晰了

• 

主题配置文件预览

• 主题文件是json文件,例如iterm2.omp.json预览一下

tips@如何确定选择想要的颜色代码

• (可选操作)可以建立一个css文件来时时预览您的颜色
• 

设置@切换主题👺

Set-PoshPrompt函数👺

• oh-my-posh init pwsh | Invoke-Expression

• 可以用-c参数顺便指定使用的主题,例如:oh-my-posh init pwsh -c "$env:POSH_THEMES_PATH\1_shell.omp.json" | Invoke-Expression

• 事实上,早期的set-poshtheme可以方便的切换主题,现在的新版本被移除了,切换主题比较麻烦点,可以自行编写函数实现类似的效果,不知道后期会不会改回来

• powershell函数配置

  • function Set-PoshPrompt
    {
        <# 
        .synopsis
        设置oh-my-posh主题,可以用 ls $env:POSH_THEMES_PATH 查看可用主题,我们只需要获取.omp.json前面部分的主题配置文件名称即可
        .example
        🚀 Set-PoshPrompt ys
        # cxxu @ cxxuwin in ~\Desktop [21:17:20]
        $ Set-PoshPrompt 1_shell
         Set-PoshPrompt iterm2
         #>
        param (
            # [Parameter(Mandatory)]
            [string]
            $Theme
        )
        oh-my-posh init pwsh --config "$env:POSH_THEMES_PATH\$Theme.omp.json" | Invoke-Expression
    }

默认主题

• Default themes

• You can find the themes in the folder indicated by the environment variable POSH_THEMES_PATH.

• For example, you can use oh-my-posh init pwsh --config "$env:POSH_THEMES_PATH\jandedobbeleer.omp.json" | Invoke-Expression for the prompt initialization in PowerShell.

官方的方法

• 官网中提到,可以通过export-poshTheme等操作来修改,但是对于复杂的主题,导出文件内容已经和源文件(.json)发生了变化,实践过程中容易报错
