When I cloned this morning, composer gave me a message that the lock file was not up to date with the latest changes in composer.json. I do not understand why, but it suggested to run `composer update`, which I did. This led to a handful of problems with php-cs-fixer, all fixed with changes to doc-blocks, and phpstan (only Writer/Xls/Worksheet required a change to code). We would presumably have had these problems at the start of next month when dependabot did its thing, so fix them now.
Fix#1681, although probably not to the originator's satisfaction. Html and Xml readers will handle documents only with a charset of UTF-8. This PR documents that restriction. No change to source code; see the original issue for explanation.
They have just issued a new release. Using that should eliminate the last of our Php8.2 unit test problems, so we will be able to change that to non-experimental when it is convenient for us.
No source code changes. Mitoteam added a change to better accomodate Cygwin; pick up their new release. While testing, discovered one test that was already skipped on Windows and needs to be skipped on Cygwin as well.
* Scrutinizer Changes
Scrutinizer appears to be working again. But the PRs that have used it have neither added new issues nor fixed existing ones. This PR should fix some exisiting; let's see what Scrutinizer does with it.
* Address Some False Positives
In Reader/Xlsx/Chart.
* R1C1 Format and Internationalization, plus Relative Offsets
Fix#1704, albeit imperfectly. Excel's implementation of this feature makes it impossible to fix perfectly. I don't know why it was necessary to internationalize R1C1 in the first place - the benefits are so minimal,and the result is worksheets that break when opened in different locales. Ugh. I can't even find complete documentation about the format in different languages; I am using https://answers.microsoft.com/en-us/officeinsider/forum/all/indirect-function-is-broken-at-least-for-excel-in/1fcbcf20-a103-4172-abf1-2c0dfe848e60 as my definitive reference.
This fix concentrates on the original report, using the INDIRECT function; there may be other areas similarly affected. As with ambiguous date formats, PhpSpreadsheet will do a little better than Excel itself when reading spreadsheets with internationalized R1C1 by trying all possibilities before giving up. When it does give up, it will now return `#REF!`, as Excel does, rather than throwing an exception, which is certainly friendlier. Although read now works better, when writing it will use whatever the user specified, so spreadsheets breaking in the wrong locale will still happen.
There were some bugs that turned up as I added test cases, all of them concerning relative addressing in R1C1 format, e.g. `R[+1]C[-1]`. The regexp for validating the format allowed for minus signs, but not plus signs. Also, the relevant functions did not allow for passing the current cell address, which made relative addressing impossible. The code now allows these, and suitable test cases are added.
* Use Locale for Formats, but Not for XML
Implementing a suggestion from @MarkBaker to use the system locale for determining R1C1 format rather than looping through a set of regexes and accepting any that work. This is closer to how Excel itself operates. The assumption we are making is to use the first character of the translated ROW and COLUMN functions. This will not work for Russian or Bulgarian, where each starts with the same letter, but it appears that Russian, at least, still uses R1C1. So our algorithm will not use non-ASCII characters, nor characters where ROW and COLUMN start with the same letter, falling back to R/C in those cases. Turkish falls into that category. Czech uses an accented character for one of the functions, and I'm guessing to use the unaccented character in that case. Polish COLUMN function is NR.KOLUMNY, and I'm guessing to use K in that case.
The function that converts R1C1 references is also used by the XML reader *where the format is always R1C1*, not locale-based (confirmed by successfully opening in Excel an XML spreadsheet when my language is set to French). The conversion code now handles that distinction through the use of an extra parameter. Xml Reader Load Test is duplicated to confirm that spreadsheet is loaded properly whether the locale is English or French. (No, I did not add an INDIRECT function to the Xml spreadsheet.)
Tests CsvIssue2232Test and TranslationTest both changed locale without resetting it when done. That omission was exposed by the new code, and both are now corrected.
* OpenOffice and Gnumeric
OpenOffice and Gnumeric make it much easier to test with other languages - they can be handled with an environment variable. Sensibly, they require R and C as the characters for R1C1 notation regardless of the language. Change code to recognize this difference from Excel.
* Handle Output of ADDRESS Function
One other function has to deal with R1C1 format as a string. Unlike INDIRECT, which receives the string on input, ADDRESS generates the string on output. Ensure that the ADDRESS output is consistent with the INDIRECT input.
ADDRESS expects its 4th arg to be bool, but it can also accept int, and many examples on the net supply it as an int. This had not been handled properly, but is now corrected.
* More Structured Test
I earlier introduced a new test for relative R1C1 addressing. Rewrite it to be clearer.
* Add Row for This to Locale Spreadsheet
It took a while for me to figure out how it all works. I have added a new row (with English value `*RC`) to Translations.xlsx, in the "Lookup and Reference" section of sheet "Excel Functions". By starting the "function name" with an asterisk, it will not be confused with a "real" function (confirmed by a new test). This approach also gives us the flexibility to do something similar if another surprise case occurs in future; in particular, I think this is more flexible than adding this as another option on the "Excel Localisation" sheet. It also means that any errors or omissions in the list below will be handled as with any other translation problem, by updating the spreadsheet without needing to touch any code.
The spreadsheet has the following entries in the *RC row:
- first letter of ROW/COLUMN functions for da, de, es, fi, fr, hu, nl, nb, pt, pt_br, sv
- no value for locales where ROW/COLUMN functions start with same letter - bg, ru, tr
- no value for locales with a multi-part name for ROW and/or COLUMN - it, pl (I had not previously noted Italian as an exception)
- no value for locales where ROW and/or COLUMN starts with a non-ASCII character - cs (this would also apply to bg and ru which are already included under "same letter")
- it does nothing for locales which are defined on the "Excel Localisation" sheet but have no entries yet on the "Excel Functions" sheet (e.g. eu)
Note that all but the first bullet item will continue to use R/C, which leaves them no worse off than they were before this change.
* Memory Leak in Sample35
All but 6 chart samples can be rendered by Sample35. Of those 6, 3 of the problems are because the script runs out of memory processing them. Adopting a suggestion from @MAKS-dev in issue #2092, adding a call to gc_collect_cycles after the charts from each spreadsheet is rendered appears to make it possible to include those 3 spreadsheets in Sample35 after all.
Also take advantage of this opportunity to correct a number (hopefully all) of Scrutinizer problems with JpgraphRendererBases.
* Minor Fix
Problem running 8.1 unit tests.
* Resolve Problems with Pie 3D Charts
Minor fix, leaving only one spreadsheet unusable in Sample35. The reasons for its unusability are now documented in the code.
* Mitoteam Made Changes
Discussing this problem with them, they decided they should make a change for Pie3D rather than forcing us to use the workaround pushed earlier. Change to require mitoteam 10.2.3, revert workaround.
* Floating-point Equality in Two Tests
Merging a change today, Git reported failures that did not occur during "normal" unit testing. The merge still succeeded, but ... The problem was an error comparing float values for equal, and the inequality occurred beyond the 14th decimal digit. Change the tests in question, which incidentally were not part of the merged changed, to use assertEqualsWithDelta.
* Egad - 112 More Precision-related Problems
Spread across 9 test members.
Fix#1929. This was already substantially fixed, but there was a lingering problem with an unexpected leading space. It turns out there was also a problem with leading zeros, also fixed. There are also problems involving commas; fixing those seems too complicated to delay these changes, but I will add it to my to-do list.
They just released a Php8.2-compatible version. We should use that version going forward. Some tests had been disabled in 8.2 due to the problems which the new release fixes; these are now restored.
* More Scrutinizer Catch Up
Continue the work of PR #3043 by attending to the 12 remaining 'new' issues.
* Php 8.1 Problem
One new null-instead-of-string problem.
This PR expands on PR #2195 from @nkjackzhang. That PR has been stalled for some time awaiting requested fixes. Those fixes are part of this PR, and additional tests and samples are added. The original request was to handle `vertical-align:middle` in Css (Excel uses `center`). This PR does its best to also handle vertical alignment Excel values not found in Css - `justify` (as `middle`) and `distributed` (as `middle`). It likewises handles valid Css values not found in Excel (`baseline`, `sub`, and `text-bottom` as `bottom`; `super` and `text-top` as `top`; `middle` as `center`).
It also handles horizontal alignment Excel values not found in Css - `center-continuous` as `center` and `distributed` as `justify`; I couldn't think of a reasonable equivalent for `fill`, so it is ignored.
The values assigned for vertical and horizontal alignment are now lower-cased (special handling required for `centerContinuous`).
The last of these changes for now. No remaining Phpstan complaints in any Writer/Xlsx. Number of lines remaining in Phpstan baseline is now below 3500.
