* This closes #1358, made a refactor with breaking changes, see details:xuri2022-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This made a refactor with breaking changes: Motivation and Context When I decided to add set horizontal centered support for this library to resolve #1358, the reason I made this huge breaking change was: - There are too many exported types for set sheet view, properties, and format properties, although a function using the functional options pattern can be optimized by returning an anonymous function, these types or property set or get function has no binding categorization, so I change these functions like `SetAppProps` to accept a pointer of options structure. - Users can not easily find out which properties should be in the `SetSheetPrOptions` or `SetSheetFormatPr` categories - Nested properties cannot proceed modify easily Introduce 5 new export data types: `HeaderFooterOptions`, `PageLayoutMarginsOptions`, `PageLayoutOptions`, `SheetPropsOptions`, and `ViewOptions` Rename 4 exported data types: - Rename `PivotTableOption` to `PivotTableOptions` - Rename `FormatHeaderFooter` to `HeaderFooterOptions` - Rename `FormatSheetProtection` to `SheetProtectionOptions` - Rename `SparklineOption` to `SparklineOptions` Remove 54 exported types: `AutoPageBreaks`, `BaseColWidth`, `BlackAndWhite`, `CodeName`, `CustomHeight`, `Date1904`, `DefaultColWidth`, `DefaultGridColor`, `DefaultRowHeight`, `EnableFormatConditionsCalculation`, `FilterPrivacy`, `FirstPageNumber`, `FitToHeight`, `FitToPage`, `FitToWidth`, `OutlineSummaryBelow`, `PageLayoutOption`, `PageLayoutOptionPtr`, `PageLayoutOrientation`, `PageLayoutPaperSize`, `PageLayoutScale`, `PageMarginBottom`, `PageMarginFooter`, `PageMarginHeader`, `PageMarginLeft`, `PageMarginRight`, `PageMarginsOptions`, `PageMarginsOptionsPtr`, `PageMarginTop`, `Published`, `RightToLeft`, `SheetFormatPrOptions`, `SheetFormatPrOptionsPtr`, `SheetPrOption`, `SheetPrOptionPtr`, `SheetViewOption`, `SheetViewOptionPtr`, `ShowFormulas`, `ShowGridLines`, `ShowRowColHeaders`, `ShowRuler`, `ShowZeros`, `TabColorIndexed`, `TabColorRGB`, `TabColorTheme`, `TabColorTint`, `ThickBottom`, `ThickTop`, `TopLeftCell`, `View`, `WorkbookPrOption`, `WorkbookPrOptionPtr`, `ZeroHeight` and `ZoomScale` Remove 2 exported constants: `OrientationPortrait` and `OrientationLandscape` Change 8 functions: - Change the `func (f *File) SetPageLayout(sheet string, opts ...PageLayoutOption) error` to `func (f *File) SetPageLayout(sheet string, opts *PageLayoutOptions) error` - Change the `func (f *File) GetPageLayout(sheet string, opts ...PageLayoutOptionPtr) error` to `func (f *File) GetPageLayout(sheet string) (PageLayoutOptions, error)` - Change the `func (f *File) SetPageMargins(sheet string, opts ...PageMarginsOptions) error` to `func (f *File) SetPageMargins(sheet string, opts *PageLayoutMarginsOptions) error` - Change the `func (f *File) GetPageMargins(sheet string, opts ...PageMarginsOptionsPtr) error` to `func (f *File) GetPageMargins(sheet string) (PageLayoutMarginsOptions, error)` - Change the `func (f *File) SetSheetViewOptions(sheet string, viewIndex int, opts ...SheetViewOption) error` to `func (f *File) SetSheetView(sheet string, viewIndex int, opts *ViewOptions) error` - Change the `func (f *File) GetSheetViewOptions(sheet string, viewIndex int, opts ...SheetViewOptionPtr) error` to `func (f *File) GetSheetView(sheet string, viewIndex int) (ViewOptions, error)` - Change the `func (f *File) SetWorkbookPrOptions(opts ...WorkbookPrOption) error` to `func (f *File) SetWorkbookProps(opts *WorkbookPropsOptions) error` - Change the `func (f *File) GetWorkbookPrOptions(opts ...WorkbookPrOptionPtr) error` to `func (f *File) GetWorkbookProps() (WorkbookPropsOptions, error)` Introduce new function to instead of existing functions: - New function `func (f *File) SetSheetProps(sheet string, opts *SheetPropsOptions) error` instead of `func (f *File) SetSheetPrOptions(sheet string, opts ...SheetPrOption) error` and `func (f *File) SetSheetFormatPr(sheet string, opts ...SheetFormatPrOption
