Fix for #2082. Xlsx Writer was writing a cell which is a formula which evaluates to boolean false as an empty XML tag. This is okay for Excel 365, but not for Excel 2016-. Change to write the tag as a value of 0 instead, which works for all Excel releases. Add test.
19_NamedRange.php was not changed to use absolute addressing when that was introduced to Named Ranges. Consequently, the output from this sample has been wrong ever since, for both Xls and Xlsx.
There was an additional problem with Xls. It appears that the Xls Writer Parser does not parse multiple concatenations using the ampersand operator correctly. So, `=B1+" "+B2` was parsed as `=B1+" "`. I believe that this is due to ampersand being treated as a condition rather than an operator; `A1>A2>A3` isn't valid, but `A1&A2&A3` is. My original PR (#1992, which I will now close) only partially resolved this, but I think moving ampersand handling from `condition` to `expression` is fully successful.
There are already more than ample tests for Named Ranges, so I did not add a new one for that purpose. However, I did add a new test for the Xls parser problem.
* Additional unit tests for VLOOKUP() and HLOOKUP()
* Additional unit tests for CHOOSE()
* Unit tests for HYPERLINK() function
* Fix CHOOSE() test for spillage
* Let's see if the tests now pass against PHP8; output file looks to be good
* Font can't be both superscript and subscript at the same time, so we use if/else rather than if/if
* Gnumeric Better Namespace Handling
There have been a number of issues concerning the handling of legitimate but unexpected namespace prefixes in Xlsx spreadsheets created by software other than Excel and PhpSpreadsheet/PhpExcel.I have studied them, but, till now, have not had a good idea on how to act on them. A recent comment https://github.com/PHPOffice/PhpSpreadsheet/issues/860#issuecomment-824926224 in issue #860 by @IMSoP has triggered an idea about how to proceed.
Although the issues exclusively concern Xlsx format, I am starting out by dealing with Gnumeric. It is simpler and smaller than Xlsx, and, more important, already has a test for an unexpected prefix, since, at some point, it changed its generic prefix from gmr to gnm. I added support and a test for that some time ago, but almost certainly not in the best possible manner. The code as changed for this PR seems simpler and less kludgey, both for that exceptional case as well as for normal handling.
My hope is that this change can be a template for similar Reader changes for Xml, Ods, and, especially, Xlsx.
All grandfathered Phpstan issues with Gnumeric are fixed and eliminated from baseline as part of this change.
* Namespace Handling using XMLReader
Adopt a suggestion from @IMSoP affecting listWorkSheetInfo, which uses XMLReader rather than SimpleXML for its processing.
* Update GnumericLoadTest.php
PR #2024 was pushed last night, causing a Phpstan problem with this member.
* Update Gnumeric.php
Suggestions from Mark Baker - strict equality test, more descriptive variable names.
As issue #2042 documents, SUM behaves differently with invalid strings depending on whether they come from a cell or are used as literals in the formula. SUM is not alone in this regard; COUNTA is another function within this behavior, and the solution to this one is modeled on COUNTA. New tests are added for SUM, and the resulting tests are duplicated to confirm correct behavior for both cells and literals.
Samples 16 (CSV), 17 (Html), and 21 (PDF) were adversely affected by this problem. 17 and 21 were immediately fixed, but 16 had another problem - Excel was not interpreting the UTF8 currency symbols correctly, even though the file was saved with a BOM. After some experimenting, it appears that the `sep=;` line generated by setExcelCompatibility(true) causes Excel to mis-handle the file. This seems like a bug - there is apparently no way to save a UTF-8 CSV with non-ASCII characters which specifies a non-standard separator which Excel will open correctly. I don't know if this is a recent change or if it is just the case that nobody noticed this problem till now. So, I changed Sample 16 to use setUseBom rather than setExcelCompatibility, which solved its problem. I then added new tests for setExcelCompatibility, with documentation of this problem.
* Defined names/formulae in ODS are prefixed by $$ when used in a formula; so we need to strip this out to fully convert them to an Excel formula
* Test for ODS Writer for DefinedNames
* First steps in the implementation of AutoFilters for ODS Reader and Writer, starting with reading a basic AutoFilter range (ignoring row visibility, filter types and active filters for the moment).
And also some additional refactoring to extract the DefinedNames Reader into its own dedicated class as a part of overall code improvement... on the principle of "when working on a class, always try to leave the library codebase in a better state than you found it"
* Provide a basic Ods Writer implementation for AutoFilters
* AutoFilter Reader Test
* AutoFilter Writer Test
* Update Change Log
* Pattern Fill style should default to 'solid' if there is a pattern fill style for a conditional; though may need to check if there are defined fg/bg colours as well; and only set a fill style if there are defined colurs
* Fix for Issue 2029 (Invalid Cell Coordinate A-1)
Fix for #2021. When Html Reader encounters an embedded table, it tries to shift it up a row. It obviously should not attempt to shift it above row 1. @danmodini reported the problem, and suggests the correct solution. This PR implements that and adds a test case.
Performing some additional testing, I found that Html Reader cannot handle inline column width or row height set in points rather than pixels (and HTML writer with useInlineCss generates these values in points). It also doesn't handle border style when the border width (which it ignores) is omitted. Fixed and added tests.
* Completion of refactoring for Excel Lookup and Reference functions
* Fix LookupRef tests checking for cell existence
* Fix a couple of now invalid callable references in the Calculation Engine lookup table
Both methods used to optionally return null if passed a
second argument. This second argument was removed entirely and the
method always returns a RowDimension or ColumnDimension respectively
(possibly creating it if needed).
This make the API more predictable and easier to do static analysis
with tools such as PHPStan.
If you relied on that second parameter, you should instead use the
`Worksheet::getRowDimensions()` or `Worksheet::getColumnDimensions()` and
check for existence yourself before calling the getters.
* DateTimeExcel - Change Names of funcWhatever to evaluate
Per discussions while MathTrig was being broken up, this would help standardize the code. This PR applies that standardization to the DateTimeExcel family of functions.
The deprecation messages in DateTime.php are changed to match the style used in PR #2005.
All Phpstan grandfathered errors (about 25) in DateTimeExcel are fixed and removed from baseline. A small number (about 5) of phpstan annotations in the source members in that directory are also fixed and eliminated.
* MathTrig - Fix Phpstan Accomodations
This should be the last of my mass changes to MathTrig. All he Phpstan violations found in baseline which are part of MathTrig are now fixed and removed from baseline. There were about 20 of these.
* MathTrig - Change Names of funcWhatever to evaluate
Per discussions while MathTrig was being broken up, this would help standardize the code. That idea was adopted partway through the breakup. This PR applies that standardization to the earlier efforts. A similar effort is required for DateTime; that will come later. This PR replaces #2006.
The only 2 remaining funcWhatevers in MathTrig are both in SUM, which required two different methods depending on whether or not string parameters were to be ignored. It seems appropriate to leave those method names non-standardized in order to require a decision about which is to be used if they are invoked internally.
3 Phpstan grandfathered errors were eliminated as part of this change, and its baseline has changed accordingly.
