Supports filtering by document ID (wildcard), POV tag, topic tag, summary status, and source type. Default output (no parameters) lists all sources sorted by DatePublished descending. .PARAMETER DocId Wildcard pattern matched against the source document ID. .PARAMETER Pov Filter to sources whose pov_tags contain this value. .PARAMETER Topic Filter to sources whose topic_tags contain this value. .PARAMETER Status Filter to sources with this exact summary_status. .PARAMETER SourceType Filter to sources with this exact source_type. .EXAMPLE Get-Source # Lists all sources sorted by date. .EXAMPLE Get-Source '*china*' # Sources whose ID matches *china*. .EXAMPLE Get-Source -Pov safetyist # Sources tagged with the safetyist POV. .EXAMPLE Get-Source -Status pending # Sources whose summary is pending. #> [CmdletBinding()] param( [Parameter(Position = 0)] [string]$DocId, [string]$Pov, [string]$Topic, [string]$Status, [string]$SourceType ) Set-StrictMode -Version Latest $ErrorActionPreference = 'Stop' $SourcesDir = Get-SourcesDir if (-not (Test-Path $SourcesDir)) { Write-Warning "Sources directory not found: $SourcesDir" return } $Folders = Get-ChildItem -Path $SourcesDir -Directory if ($Folders.Count -eq 0) { Write-Warning "No source folders found in $SourcesDir" return } $Results = [System.Collections.Generic.List[PSObject]]::new() foreach ($Folder in $Folders) { $MetaPath = Join-Path $Folder.FullName 'metadata.json' if (-not (Test-Path $MetaPath)) { continue } try { $Meta = Get-Content -Raw -Path $MetaPath | ConvertFrom-Json } catch { Write-Warning "Failed to parse ${MetaPath}: $_" continue } # Safe property accessor for metadata that may lack optional fields $Props = $Meta.PSObject.Properties # --- Filters --- if ($DocId -and $Meta.id -notlike $DocId) { continue } if ($Pov) { $PovArr = if ($Props['pov_tags']) { $Meta.pov_tags } else { @() } if ($PovArr -notcontains $Pov) { continue } } if ($Topic) { $TopicArr = if ($Props['topic_tags']) { $Meta.topic_tags } else { @() } if ($TopicArr -notcontains $Topic) { continue } } if ($Status) { $SumStatus = if ($Props['summary_status']) { $Meta.summary_status } else { $null } if ($SumStatus -ne $Status) { continue } } if ($SourceType) { $SrcType = if ($Props['source_type']) { $Meta.source_type } else { $null } if ($SrcType -ne $SourceType) { continue } } $Results.Add([PSCustomObject]@{ PSTypeName = 'AITriad.Source' DocId = $Meta.id Title = if ($Props['title']) { $Meta.title } else { $null } Authors = if ($Props['authors']) { $Meta.authors } else { @() } DatePublished = if ($Props['date_published']) { $Meta.date_published } else { $null } SourceType = if ($Props['source_type']) { $Meta.source_type } else { $null } SummaryStatus = if ($Props['summary_status']) { $Meta.summary_status } else { $null } PovTags = if ($Props['pov_tags']) { $Meta.pov_tags } else { @() } TopicTags = if ($Props['topic_tags']) { $Meta.topic_tags } else { @() } OneLiner = if ($Props['one_liner']) { $Meta.one_liner } else { $null } }) } if ($Results.Count -eq 0) { Write-Warning 'No sources matched the specified filters.' return } $Results | Sort-Object { if ($_.DatePublished) { [datetime]$_.DatePublished } else { [datetime]::MinValue } } -Descending } |
