Print a nicely formatted file tree in Powershell

Often I'll find it helpful to give a LLM context of my file structure for coding projects, so I co-wrote this script to only grab the relevant files and output them in a nicely formatted tree.

As you can see, it ignores common directories in a VS code (Nuxt and Vue) project and in a Pycharm (Python) project. It also only grabs files with approved extensions.

function Print-Tree {
    param (
        [string]$Path,
        [string]$Indent = ""
    )

    $excluded = @('.nuxt', 'node_modules', '.venv', 'venv', '.idea', '__pycache__')
    $extensions = @(".py", ".txt", ".md", ".ini", ".ts", ".json", ".vue", ".yaml", ".env")

    
    Get-ChildItem -Path $Path | Where-Object { $_.Name -notin $excluded } | ForEach-Object {
        if ($_.PSIsContainer) {
            Write-Output "$Indent|-- $($_.Name)"
            Print-Tree -Path $_.FullName -Indent "$Indent|   "
        } else {                                           # Use this line for all extensions
        # } elseif ($extensions -contains $_.Extension) {  # Use this line to only include whitelisted extensions

            Write-Output "$Indent|-- $($_.Name)"
        }
    }
}

# Call the function with the initial path
Print-Tree -Path "C:\Users\david\source\davehague-site"

It's been really helpful to have this script to give the LLM extra context about my project.
