tessera_ods 0.2.2

OpenDocument (.ods) support for the tessera pivot-table engine: import a sheet as a data source, export a cube or a plain table as a formatted sheet. Pure Dart.

0.2.2

• Fix: with archive 4.4.0 or later, exported files could not be opened by LibreOffice ("source file could not be loaded"): that version's ZipEncoder writes every entry with a data descriptor which only the local header announces. The exporters now zip with a small writer of their own — CRC and sizes in the local headers, no data descriptors — that works the same with every archive 4.x. Output is also deterministic now (fixed entry timestamps).

0.2.1

• OdsTableExporter: writes an ExportTable — plain rows, or a FactTable through ExportTable.ofFacts — as a filterable data table rather than a pivot, the counterpart of XlsxTableExporter: filter buttons over the table (an anonymous database range, as LibreOffice writes it), the header frozen and repeated on printed pages, typed numbers, booleans and dates (date or date-time by the column's type), a number style per ExportColumn.numberFormat, content-sized or fixed widths, the look from the engine's TableExportTheme. Line breaks, tabs and runs of spaces in texts are kept.
• Text no longer carries characters XML 1.0 forbids (control characters, unpaired surrogates, U+FFFE/U+FFFF), which made the document unreadable. Affects OdsCubeExporter too.
• Requires tessera 0.2.2 (ExportTable, TableExportTheme).

0.2.0

• Requires tessera 0.2.0; no changes of its own. Cubes with the new aggregates (statistical, cell formulas, "show values as") export like any other.

0.1.0

• OdsDataSource: streams one sheet of an .ods document as typed rows (floats/ints, dates and date-times, booleans, strings with text:s and line breaks; repeated columns and rows), sheet selection, skipped rows, header-less sheets. Sendable to the import isolate.
• OdsCubeExporter: writes a CubeLayout as a formatted sheet — merged "rotated L" group headers, one column per exported aggregate, level fills, fonts and number format from the engine's CubeExportTheme, content-sized columns, frozen headers.
• example/main.dart: command-line round trip on example/sales.ods.
• archive constraint widened to >=4.0.7 <5.0.0 so the package resolves next to package:pdf.
