Want to get a list of tags from a git repo?

tags_since.x.ps1

Function Tags-Since([String] $datesSince = "2019-04-01") {
  git rev-parse --is-inside-work-tree

  if($LastExitCode -ne 0)
  {
    Write-Host "Please invoke this function from within a git repository folder. Exiting."
    exit(1)
  }


  $allTags = git log --tags --simplify-by-decoration --pretty="format:%ai::%d"
  $dateSince = [DateTime]::Parse($datesSince)
  $tagObjects = @()

  foreach($tagObject in $allTags)
  {
    $parts = $tagObject.Split("::")
    foreach($part in $parts){ $part = $part.Trim() }

    $TagRegex = "tag\: (?<tag>[^,)]*)"
    $tagList = @()

    Select-String $TagRegex -input $parts[1] -AllMatches `
      | % { $_.matches } `
      | % { $tagList += $_.Groups['tag'].Value }

    $tagObjects += New-Object PSObject -Property @{
      Date = [DateTime]::Parse($parts[0])
      TagList = $tagList
    }
  }
  
  $filteredTagObjects = $tagObjects | where { $_.TagList.Length -gt 0 -and $_.Date -ge $dateSince}
  $filteredTagObjects = $filteredTagObjects | Sort-Object -Property Date -Descending

  foreach($tagObj in $filteredTagObjects)
  {
      foreach($tag in $tagObj.TagList)
      {
        Write-Host $tag 
      }
  }
