These glitches were probably due to PR #3622.
- Excel may not properly identify the selected cell on a sheet if freeze panes is in effect, even though the Xml points to the correct pane and the correct selected cell is specified for that pane.
- Worksheet::calculateColumnWidths may alter activePane.
Fix#2809. User felt font files should be searched recursively. The problem could be overcome merely by specifying a more precise font location. However, user has a point - the file layout on user's system is pretty common, and can be integrated into PhpSpreadsheet code easily. As a bonus, the DocBlock for setTrueTypeFontPath, which the user felt was misleading, doesn't even have to change.
Fix#3819. Excel can add these prefixes (basically invisible to end-user). Formula translation in PhpSpreadsheet fails when dealing with these unexpected prefixes, and, even if it handled it correctly, the unexpected prefixes confuse the users. I have changed to strip those prefixes when translating to a locale. This is probably not perfect, but is almost certainly good enough. I could easily add the same change when translating from a locale to English, but I don't think there's a good use case for that, so am opting not to do so for now.
The documentation mentions `translateFormulaToLocale` and `translateFormulaToEnglish`. Neither of these exist; both names are preceded by an underscore. I have changed the code to match the documentation rather than vice versa, retaining deprecated versions of the underscored routines which merely invoke the non-underscored routines.
Fix#3820. When cloning a worksheet, special handling is already included for `cellCollection` and `drawingCollection`. It needs to be added for `tableCollection` as well. In theory, `chartCollection` also needs it. However, there are no clone methods for any of the Chart objects, so that will be a substantially larger effort. There is no need to delay this fix waiting for that.
* Automate Function-by-Name and Function-by-Category Docs
Examining whether it is possible to analyze the 2 Php scripts in the bin directory even though they lack a .php extension, I found that the docs generated by `generate-document` had not been updated in over a year even though support for a number of functions (e.g. ARRAYTOTEXT) had long ago been implemented. The files generated by the other script `generate-locales` are automatically generated as part of the unit test suite, and I can't see any reason not to do the same for `generate-document`.
It isn't totally clear that the 2 scripts in bin are needed any more now that each has an equivalent in the unit test suite. For now, I'm keeping them, and allowing them to be analyzed by phpcs, php-cs-fixer, and phpstan.
* Reflection Not Required
Remove it from bin scripts and DocumentGeneratorTest.
* Better Html/Css Display for Function Lists
* Redesign Features Cross Reference Doc
It was inaccurate, and pretty much impossible to read in entirety. This version should be easier to read, and to correct. That's important, because there are almost certainly new inaccuracies in this version.
* Add Html to Features Cross-Reference Readers
This was suggested by the investigation of issue #3811. No fix is necessary for the issue. However, two possible code solutions (Php setlocale, which comes with certain design flaws, and StringHelper set(Decimal/Thousands)Separator were suggested, and neither is adequately tested. This PR adds such tests.
Unusually, getting StringHelper Decimal Separator, Thousands Separator, and Currency Code can result in a change to those properties. So, the existing design in several tests where those properties are captured in Setup and restored in Teardown do not work quite as designed. Instead, the ability to set those properties to their default value (null) is added, and the tests re-done to restore the default in Teardown.
The two methods yield the same results when parsing input. However, they diverge when examining output fields through `getFormattedValue`. Such output is currently correct (usually) when using setlocale, but not when using StringHelper. The former works through the 'trick' of using `sprintf(%f)`, which generates a locale-aware string. However, using non-locale-aware `sprintf(%F)` followed by `str_replace` will produce the correct result for both setlocale and StringHelper. One place in the code uses a cast to string, which is incorrect for both methods. Following that up with the same str_replace makes it correct for both. These changes permit, but do not require, the user to avoid setlocale altogether.
It remains an open question whether Settings/Calculation::setLocale should set DecimalSeparator, CurrencySeparator, and CurrencyCode. That makes logical sense, but it would be a breaking change, and having to explicitly set those values when using setLocale does not seem especially burdensome. For now, such a change will not be made.
* Let Phpstan Run on Samples
Phpstan currently analyzes all source and test members. We already run phpcs and php-cs-fixer on samples as well. I would expect that samples are often used as templates for code in userland; it behooves us to be at least as careful with those members as for the others which are already being analyzed. Aside from 1300+ messages `Variable $helper might not be defined.`, which will be suppressed in phpstan.neon.dist, there are really only a few changes needed for sample members, so that part of the code base was already in good shape, and is now even better. No annotations were needed.
* Scrutinizer 2 out of 3
1 false positive, now suppressed; fix other 2.
* Remove Dead Code
* Very Minor Changes
* Add infra
Fix#3782. A signature of the ReflectionMethod constructor will be deprecated, and PhpSpreadsheet runs afoul of that change in one place. Php8.4 is not yet available in any form, and I am reluctant to make this change until we see that the issue is real (and that this PR fixes it), so am leaving this PR in draft status till then.
I note that one Excel function `PI` is implemented not as a class method in PhpSpreadsheet, but rather as a call to the native Php function `pi`. The ReflectionMethod call is subject to a TypeError in the changed code, but that is already the case. We haven't seen a TypeError because (a) it will arise only if the caller supplies an argument to the function (which must be called with zero arguments), and (b) there are no test cases for that function. The code is slightly cleaned up, and test cases are now added. This is not an important enough problem to rush this PR - the existing code (and the changed code), rather than failing with TypeError, will fail with a CalculationException (wrong number of arguments) before it gets to the TypeError; that is the correct behavior.
Fix#3807. Function attempts to rationalize `..` in filenames in a way that normally works just fine. Reporter notes that at least one of the filenames that will be analyzed when a spreadsheet is read can be maliciously altered in a manner which does not harm Excel when reading the file, but which puts PhpSpreadsheet into a loop. This PR fixes the problem.
* Xlsx Support Flipping of Image
Fix#731. Opened over 5 years ago, probably the second oldest problem I've worked on. Images attached to an Xlsx spreadsheet can be rotated, which is supported by PhpSpreadsheet. They can also be flipped along their horizontal and/or vertical axes, and that has not been supported. This PR adds that support.
* Update CHANGELOG.md
* Chart Dynamic Title and Special Font Properties
Fix#3797. Excel allows a Chart Title to be a formula, albeit a very rigidly limited one. It can only be a reference to a single cell, and the worksheet name must be specified, and the column and row must be absolute. Methods are added to Chart/Title to accommodate this (and styling for it). This will be handled for input/output for Xlsx, and for output for Html.
The sample file which was submitted with this issue demonstrated that something else was missing. When setting the font for a chart title in Excel, you can specify all-caps or small-caps, options not available for most cell formatting. These are now added.
The sample file also fell into the category of spreadsheets which lose one or more charts when converted to Html. I have redone the "extend rows and charts" logic in Html Writer. It is now clearer (I hope) and more efficient, and hopefully this problem will not arise again.
* Scrutinizer 50/50
One false positive, one correct "unused parameter".
* Sheet Background Images
Fix#1649, a 3-year-old issue long marked "stale". Excel supports background images on sheets; now PhpSpreadsheet will as well. Support is limited to Xlsx (read and write) and Html (write only). As far as I can tell, Excel Xml and Gnumeric do not support this, nor, of course, do Csv and Slk; Excel Xls does, but, as usual, how to handle it in BIFF format is a mystery; LibreOffice ODS supports it differently than Excel, and this is just another of many ODS style properties not currently supported by PhpSpreadsheet.

* Address Some Chart Problems
Fix#3767. The basic problem in that issue was user error, but it exposed a couple of problems in code which are being addressed.
When a spreadsheet with charts is loaded without the includeCharts option and then saved, a corrupt spreadsheet is created. I believe this has been the case for quite some time. Nothing in the test suite covers this scenario. It is, in fact, a difficult thing to test, since the problem is exposed only when the file is opened through Excel. The specific problem is that a rels file generated by the output writer continues to refer to the drawing file which described the chart, but that file is not included (and not needed) in the output spreadsheet. The resolution is kludgey. The information that the file will not be needed is not available when the rels file is written. But, when it comes time to write the drawing file, it is known whether the rels file included it. So, if nothing else has caused the file to be generated, it is written out as a basically empty xml file after all. This solves the problem, but I will continue to search for a less kludgey solution. This solution is, at least, testable; if a different solution is applied later on, the test being introduced here is likely to break so a new one will be needed.
When the provided spreadsheet is loaded with the includeCharts option and then saved, an error is exposed in processing the Chart Title caption when it doesn't exist. The change to Writer/Xlsx/Chart is simple and clearly justifiable. What is peculiar is that the error does not arise with release 1.29, but does arise with master. It is not at all clear to me what has changed since the release to expose the error - the code in question certainly hasn't changed. It is difficult to isolate changes because of the extensive number of changes following on the elimination of Php7.4 as a supported platform.
The provided spreadsheet is unusual in at least two senses. When opened in Excel, it will show a clearly default value for the chart title, namely 'Chart Title'. I cannot find anything in the xml corresponding to that text. Since I have no idea why Excel is using that title, I will not try to duplicate its behavior, so that loading and saving the provided spreadsheet will omit the chart title. I will continue to investigate.
The other sense in which it is unusual is that it includes some style files in the same directory as the chart. I doubt that PhpSpreadsheet looks at these. The styling after load and save seems to mostly match the original, although there is at least one color in the graph which does not match. I imagine it would be pretty complicated to formally support these files.
* Unused Assignment
* Slk Shared Formulas
Fix#2267. The Slk format has a way to express a "shared formula", but the Slk reader does not yet understand it. Thanks to @SheetJSDev for documenting the problem and pointing the way towards a solution. It has taken a long time to get there. Part of the problem is that I have not been successful in getting Excel to use this type of construction when saving a Slk file. So I have resorted to saving a Slk file where shared formulas *could* be used, and then editing it by hand to actually use them. It would not surprise me in the least to have neglected one or more possible ways to specify a shared formula; but, at least the issue as documented is resolved, and if new issues arise, we'll probably be in better shape to deal with them.
* Update CHANGELOG.md
* Theme File Missing But Referenced in Spreadsheet
Fix#3770. A rels file points to a non-existent theme file in the spreadsheet. In other similar cases (e.g. PR #3771), Excel opens such a spreadsheet, but with an error pop-up. Not so with this file; it just opens the spreadsheet without the pop-up. PhpSpreadsheet will now account for this unusual situation as well.
* Update CHANGELOG.md
* Performance Improvements for Csv Reader
Investigating issue #381, a means was suggested to duplicated a problem, but no problem occurred ... except for performance. This involved a spreadsheet with a large number of cells, definitely not PhpSpreadsheet's strong point; even so, the program (entirely available in the issue) took a disastrous two or so hours to complete on my system. Looking at the Csv Reader code, several opportunities to cache results and avoid function calls jumped out, none of which seem to materially add to the maintenance burden of the program. Testing these changes resulted in a run time of about 20 minutes, still hardly a thing of beauty, but a huge improvement over the original and therefore worth proceeding with.
* Redo CsvIssue2232Test
Test cases included duplicates, and didn't account for some things (e.g. French locale will treat both 'vrai' and 'true' as true).
* Additional Optimization
* Eliminate Some Phpstan Annotations
Some changes are possible due to Php8+ features like null-safe operators and Stringable.
* Possible Uninitialized Variable
Scrutinizer might be technically correct.
* CellAddress Static -> Self
I don't understand the use case for extending it, which would be the reason for using static rather than self.
* Update Worksheet.php
* Allow Users to Support Additional Tags in Helper/Html
Fix#3751. User wants to add bullets for list items, and possibly handle table rows and other currently unsupported tags where one size might not fit all.
* Update CHANGELOG.md
* Added Conditional Formatting: ColorScale for Xlsx
* Add Reader Support, Tests, Sample
Also correct Phpstan and phpcs problems.
* Update cond08_colorscale.php
* Improve Coverage
* More Coverage Improvements
* Use StyleReader for Colors for ColorScale and DataBar
The implementation of DataBar looks for an rgb attribute, but the color may be provided via theme attribute instead. The initial implementation for ColorScale did the same. Change both to use the existing code in Reader\Xlsx\Styles to parse the color.
* Change Some Doc Blocks to Type Declarations

Because they tend to clutter our code a lot and unfortunately, there are
lots of false positives. Instead, it would probably be better to deal
with false positives out of band, via the Scrutinizer web UI.

* Add iterateOnlyExistingCells to Constructors
Fix#3721. That issue can already be handled, but requires several statements when one ought to suffice. Adding an extra parameter to the RowCellIterator and ColumnCellIterator constructors is useful, easy, and becomes especially practical now that our supported Php releases all support named parameters (see new test Issue3721Test).
* Update Column.php
* Update .php-cs-fixer.dist.php
* Update Row.php
* Update Column.php
* Update ByColumnAndRowTest.php
* Unexpected Namespacing in rels File
Fix#3720. Third-party product created a spreadsheet which PhpSpreadsheet could not read because of unexpected namespacing in workbook.xml.rels.
The file which demonstrated the problem was attached to #3423, however I do not believe it was related to the original problem. Nevertheless, the original issue specifically called out Protection, so I put some Protection tests in the validation test for the fix. In doing so, I found that Style/Protection is particularly confusing. Its properties will often have the value `inherit`, which isn't all that helpful; and, even when the `locked` value is `protected`, the cell won't actually be locked unless the sheet is protected as well. The `hidden` property is even more obscure - it applies only to formulas, and refers to hiding the property on the formula bar, not in the cell. I have added methods `isLocked` and `isHiddenOnFormulaBar` to `Cell`. I corrected the docs to explain this. And, as long as I was looking at the docs, I corrected some examples to use `getHighestDataRow/Column` rather than `getHighestRow/Column`, a frequent problem for users (e.g. #3721).
As a side note, the change to Cell.php is my first use of the nullsafe operator. This is one of many new options available now that we require Php8.0+.
* Minor Simplifications
* Scrutinizer
It's being silly again. In many tests, we test a variable for non-null, then use that variable later and Scrutinizer knows it's not null. Not here. Oh well.
* Add Methods
Test if protected without allocating cell if it doesn't exist.
