What's New

AnyDataMarshaler — render arbitrary data, not just TableData

New RenderAnyData() dispatch for rendering any Go value. JSON, YAML, and TOML register handlers automatically.

output.RenderAnyData(myStruct, output.FormatJSON, output.RenderOptions{})

All 16 formats now dispatch via RenderTableData()

D2, DOT, Mermaid, and PlantUML now register TableDataMarshaler via init(). Previously only 10 formats were registered.

Generic formatRegistry[T]

Thread-safe generic registry replaces 3 separate mutex+map patterns. Same formatRegistry[T] backs shape capabilities, table-data marshalers, and any-data marshalers.

AddRowChecked

err := data.AddRowChecked(row) // returns ErrColumnMismatch if column count differs from headers

NOM event constants

nom.EventWorkflowStarted  // instead of "workflow.started"
nom.EventActivityCompleted // instead of "activity.completed"

What's Changed

• Added: RenderAnyData, RegisterAnyDataMarshaler, RegisteredAnyDataFormats, RegisteredTableDataFormats
• Added: TableData.AddRowChecked() with column-count validation
• Added: nom.Event* typed string constants
• Added: D2, DOT, Mermaid, PlantUML register as TableDataMarshaler
• Changed: Generic formatRegistry[T] replaces 3 mutex+map patterns
• Changed: dt.Build() errors propagated instead of silently discarded
• Changed: NOM timing cache async save errors now logged
• Deprecated: delimited.MarshalTSV(data any) → use MarshalTSVFromTableData
• Deprecated: graph.NewGraphNodeID/NewGraphNodeLabel → use output.NewBrandedID
• Deprecated: nom.ParseActivityID/ParseWorkflowID → use direct type conversion

md.SetHeaders([]string{"Name", "Status"})
md.AddRow([]string{"go-output", "shipped"})
out, _ := md.Render()
fmt.Println(out)
