Document in type system (not just in text for humans) that
all SheetViewOptionPtr are also SheetViewOption (well, if not nil).
This improves documentation visible with godoc but this simple change
also allows more flexibility to manipulate SheetViewOption programatically
such as saving and restoring values:
var opt excelize.ShowFormulas
opt = new(excelize.ShowFormulas)
_ = xl.GetSheetViewOptions(sheet, -1, opt)
_ = xl.SetSheetViewOptions(sheet, -1, opt)
Two new methods:
- SetSheetViewOptions(sheetName string, viewIndex int, opts ...SheetViewOption) error
- GetSheetViewOptions(sheetName string, viewIndex int, opts ...SheetViewOptionPtr) error
The option values are given by the user through types that have privates methods
that implement the private SheetViewOption and SheetViewOptionPtr interfaces:
- DefaultGridColor(bool)
- RightToLeft(bool)
- ShowFormulas(bool)
- ShowGridLines(bool)
- ShowRowColHeaders(bool)
Examples:
err := xl.SetSheetViewOptions("Sheet1", -1, excelize.ShowGridLines(true))
var showGridLines excelize.ShowGridLines
err := xl.GetSheetViewOptions("Sheet1", -1, &showGridLines)
Fixes#145.
