Windows Terminal bashrc-like Customization

• Use echo $PROFILE to check which profile.ps1 file your Windows Terminal is using.

  

• Allow locally written scripts by searching for the keyword: remote signed.
• Use . $PROFILE to apply your changes like source ~/.bashrc, or restart the terminal.
• Define constants (export xxx=xxxxxx): Set-Variable -Name “xxx” -Value “xxxxxxx” -Option Constant
  • You can then use them with $xxx.
  • Or directly use $xxx = xxxxxx.
• Define functions (alias f="xxxx"): function f { xxxx }
  • LLMs probably do this better than you.
  • For example:
    • Quickly open your magical tools library:

        function proj {
            param (
                [string]$projName,
                [switch]$vscode,
                [switch]$explorer
            )
      
            if ($projName) {
                $projPath = Join-Path -Path $funpy -ChildPath $projName
                if (Test-Path $projPath) {
                    Set-Location $projPath
                    if ($explorer) {
                        explorer.exe .
                    }
                    if ($vscode -or -not $explorer) {
                        code .
                    }
                } else {
                    Write-Error "The project '$projName' does not exist."
                }
            } else {
                Get-ChildItem -Path $funpy -Directory | ForEach-Object { $_.Name }
            }
        }
      

• Nice, but what if I forgor?

  • https://stackoverflow.com/questions/15694338/how-to-get-a-list-of-custom-powershell-functions:

      # get custom functions
      $sysfunctions = Get-ChildItem function:
      function custom {Get-ChildItem function: | Where-Object {$sysfunctions -notcontains $_} }
    

• If you would like to be more elegante~
  • Write or have a big model help generate a profile.ps1 document, such as readme.md.
  • Install streamlit in your local Python environment.

  • Write the following simple streamlit webpage to read and display the markdown.

      import streamlit as st
      import os
      import subprocess
    
      # Set the page configuration to use the wide layout
      st.set_page_config(layout="centered")
    
      # Retrieve the profilePath variable from PowerShell
      # Make sure you have defined the profilePath variable in your environment or profile.ps1, which is the folder where your $PROFILE resides.
      profile_path = subprocess.check_output(['powershell', '-Command', '(Get-Variable -Name profilePath).Value'], text=True).strip()
    
      doc_path = os.path.join(profile_path, 'readme.md')
    
      with open(doc_path, 'r', encoding='utf-8') as file:
          readme_content = file.read()
    
      st.markdown(readme_content)
    

  • Also, define a simple function to replace manual commands.

      function doc {
          $doc_py_path = Join-Path -Path $profilePath -ChildPath "doc.py"
          streamlit run $doc_py_path
      }
    

• Now, you can simply type doc in the command line to get:
