workbook::operator== was comparing the value of the raw pointer held by two std::unique_ptr's. By definition, this is always false in a well behaved program (if it's true, things go bang...). This then led to adding equality operators to nearly every other struct/class in xlnt to support workbook::operator==
workbook::load and the non-default ctors for loading data from a file are tested using the now functional equality operator
NOTE: a large number of copy ctors need updates/fixing. Many should be defaulted
Issue #298
- all 4 are simply duplicating existing behaviour, but perhaps we can get a more optimal version in future
- istream ctor is intended as an extension point that can then be used to create free/static functions to work with any future data source (vector), while the path ctor is a convenience function for the common case (from file)
- hyperlinks to cells and ranges are complete
- hyperlink::display is now set as well as the cell value (in excel these can be different)
-- if a cell is empty, display is equal to value text
-- if a cell has a value, display can be just about anything
- This version copies excel in that display is completely ignored once value is set
- All hyperlink tests are now part of the cell test suite (not the worksheet test suite which the majority were previously located)
-- NOTE: ctor was removed because it can't have been in use, and is duplicated by the overload below it. A pair parameter is only optimal in a very limited number of use cases, and then only slightly over the begin/end overload
-- roundtripping namespaces requires modifications of the parser used for the entire worksheet as there does not appear to be a way to track the namespace changes without listening/registering for the event. This (ofcourse) breaks lots of other things...
-- custom_heights was the only test sheet where the integral value was being saved with a trailing ".0"
-- Updated tests to expect the new values
-- added the new property "defaultColWidth"
-- tolower takes chars and returns chars, types are int because C only deals with ints
-- format parameter is size_t but there is no std parsing function that returns size_t. stoull is used instead as the widest alternative, and then the cast is applied to suppress the conversion warnings
-- to encode: copy the string into unicodelookup.com. Take the hex representation and pad to 4 characters with '0's, prefixing each character with '\u'
