Get String as a PowerShell Function Argument Without Quotes Necessary

usecase

The concern is documenting the Powershell’s pattern to accept an argument as [string] with multiple words without quotes necessary.

1. search-google

Function search-google {
    $query = 'https://www.google.com/search?q='
    $args | % { $query = $query + "$_+" }
    $url = $query.Substring(0, $query.Length - 1)
    start "$url"
}

• this works

2. convert to filename

• the aim here is to pass a string say

90.1 Sparse is Better than Beautiful

• and get copied to the clipboard

90.1-Sparse-is-Better-than-Beautiful.md

• this was my old way — with quotes necessary around the argument

function convertTo-filename ($docTitle) {
    $filename = ("$docTitle" -replace "\s", "-") -replace ".+", "$&.md"
    $filename | clip
    Write-Host "$filename clipped" -ForegroundColor Darkcyan
}
▶ convertTo-filename "90.1 Sparse is Better than Beautiful"
90.1-Sparse-is-Better-than-Beautiful.md clipped

• new

function convertTo-filename {
    $docTitle = ""
    $args | % {$docTitle += "$_ "}
    $docTitle = $docTitle.substring(0, $docTitle.Length - 1)
    $filename = ("$docTitle" -replace "\s", "-") -replace ".+", "$&.md"
    $filename | clip
    Write-Host "$filename clipped" -ForegroundColor Darkcyan
}
▶ convertTo-filename 90.1 Sparse is Better than Beautiful
90.1-Sparse-is-Better-than-Beautiful.md clipped
