With the deprecation of `auto_detect_line_endings` in Php8.1, there have been some tickets (issue #2609 and PR #2438). Although the deprecation message is suppressed, users with a homegrown error handler may still see it. I am not very concerned about that symptom, but I imagine that there will be more similar tickets in future. This PR adds a new property/method to Reader/CSV to allow the user to avoid the deprecated code, at the negligible cost of being unable to read a CSV with Mac line endings even on a Php version that could support it.
These changes were already implemented as PR #2428. They were, alas, regressed by PR #2585. If at first you don't succeed ...
As configured, Phpstan running under Php7 reports no errors. However, running under Php8, it reports 100 (!) errors. The vast majority of these are due to two reasons:
- renaming parameters in Php builtin functions in preparation for named parameters.
- using the new class GdImage rather than type resource as the argument type for many image-based functions.
Regardless of the cause, this will be a problem sooner or later. This PR is an attempt to get ahead of that problem. For source members, it tweaks only the Phpstan configuration files, without changing any PhpSpreadsheet code. For the small number of test members involved, the code is fixed. Php7 and Php8 both report no errors with this configuration.
Because this involves no changes to code, and because Phpstan baseline is a common cause of merge difficulties, I will probably merge this in a day or two, more quickly than I customarily do.
Note that this method is used when translating Excel functions between en and other locale languages, as well as when converting formulae between different spreadsheet formats (e.g. Ods to Excel)
Nor is this a perfect solution, as there may still be issues when function calls have array arguments that themselves contain function calls; but it's still better than the current logic
Fix#2499, which see for details of an obscure problem affecting both PhpSpreadsheet and Excel. Add support for palette contained in workbook styles. This seems to be a very rare occurrence, so allow it only when the palette contains exactly 64 entries. If there are other possibilities, we'll presumably have a new workbook to guide us how to handle them. Also add some tests for specification of indexed color without palette, another rarity (no in-range examples amongst our current files). Also change one private static array, initialized once at run-time and never changed, to a constant.
* Capture of worksheet name in Calculation Engine cell references modified to handle apostrophe and quote marks, and made non-greedy to avoid ensure that multiple quoted worksheet names in a formula aren't all captured in one go
* Split some of the unit tests into separate test classes
* Initial work on implementing Array-enabled for the HLOOKUP() and VLOOKUP() functions
* In the MATCH() function, we should also use `evaluateArrayArgumentsIgnore()` because the lookupvalue and matchType arguments can be array arguments, but lookupArray is always a dataset matrix
Implement Array-enabled for ERROR.TYPE() function
Extract ERROR.TYPE() function tests into separate test file
Extract error function tests into separate test files
And thus complete the implemented Information functions
* First steps toward array-enabling the information functions
Also includes moving unit tests out from Functions and into a separate, dedicated Information folder
* Resolve issue with IF(), branch pruning and calculation cache (ensure that we don't convert the if condition to a bool before we've tested to see if it evaluates to an error)
More refactoring
Fix#2523. This isn't actually a fix; the problem was reported and confirmed for 1.21, but had already been fixed in master (and remains fixed in 1.22). This PR just adds a unit test for the original problem.
* Start work on array-enabling the Lookup and Reference functions
Requires a new method (`evaluateArrayArgumentsSubsetFrom()`) in the `ArrayEnabled` Trait to handle functions where the arguments that need special array handling are trailing rather than leading arguments
* Start work on array-enabling the Lookup and Reference functions
Requires a new method (`evaluateArrayArgumentsSubsetFrom()`) in the `ArrayEnabled` Trait to handle functions where the arguments that need special array handling are trailing rather than leading arguments
* Split Information functions into a dedicated class and namespace and categorise as Value or Error
* Refactor all error functions into the new ExcelError class
* Enable array-readiness for more Math/Trig functions; CEILING() FLOOR() (and variants), TRUNC(), BASE() and the various Logarithms
* Minor refactoring
* ReferenceHelper@insertNewBefore now changes for missing columns before replacing and deleting columns
* Changelog updated
* Fixed code style
* Added assertion for all cells. Change bugfix implementation to use `createNewCell` on Worksheet
* Additional assertions
Fix#2542. Xlsx Reader is expecting a `sz` tag when reading RichText, but it is not required, and PhpSpreadsheet issues a warning message when it is missing.
* WIP Namespacing Phase 2 - Styles
This is part 2 of a several-phase process to permit PhpSpreadsheet to handle input Xlsx files which use unexpected namespacing. The first phase, introduced as part of release 1.19.0, essentially handled the reading of data. This phase handles the reading of styles. More phases are planned.
It is my intention to leave this in draft status for at least a month. This will give time for additional testing, by me and, I hope, others who might be interested.
This fixes the same problem addressed by PR #2458, if it reaches mergeable status before I am ready to take this out of draft status. I do not anticipate any difficult merge conflicts if the other change is merged first.
This change is more difficult than I'd hoped. I can't get xpath to work properly with the namespaced style file, even though I don't have difficulties with others. Normally we expect:
```xml
<stylesheet xmlns="http://whatever" ...
```
In the namespaced files, we typically see:
```xml
<x:stylesheet xmlns:x="http://whatever" ...
```
Simplexml_load_file specifying a namespace handles the two situations the same, as expected. But, for some reason that I cannot figure out, there are significant differences when xpath processes the result. However, I can manipulate the xml if necessary; I'm not proud of doing that, and will gladly accept any suggestions. In the meantime, it seems to work.
My major non-standard unit test file had disabled any style-related tests when phase 1 was installed. These are now all enabled.
* Scrutinizer
Its analysis is wrong, but the "errors" it pointed out are easy to fix.
* Eliminate XML Source Manipulation
Original solution required XML manipulation to overcome what appears to be an xpath problem. This version replaces xpath with iteration, eliminating the need to manipulate the XML.
* Handle Some Edge Cases
For example, Style file without a Fills section.
* Restore RGB/ARGB Interchangeability
Fix#2494. Apparently EPPlus outputs fill colors as `<fgColor rgb="BFBFBF">` while most output fill colors as `<fgColor rgb="FFBFBFBF">`. EPPlus actually makes more sense. Regardless, validating length of rgb/argb is a recent development for PhpSpreadsheet, under the assumption that an incorrect length is a user error. This development invalidates that assumption, so restore the previous behavior.
In addition, a comment in Colors.php says that the supplied color is "the ARGB value for the colour, or named colour". However, although named colors are accepted, nothing sensible is done with them - they are passed unchanged to the ARGB value, where Excel treats them as black. The routine should either reject the named color, or convert it to the appropriate ARGB value. This change implements the latter.
Provide a separate "subset" method in the `ArrayEnabled` Trait, that allows a subset of arguments to be tested for array returns.
Set up basic tests for `WORKDAY()`
* Initial work enabling Excel function implementations for handling arrays as aguments when used in "array formulae".
So far:
- handling for single argument functions
- for functions where only one of the arguments is an array (a matrix or a row/column vector)
- for when there are two array arguments, and one is a row vector, the other a column vector
- for when there are either 2 row vectors, or 2 column vectors
- for a matrix and either a row or column vector
Will work ok, as long as there are no more than two array arguments; still need to identify the logic to apply when there are more than two arrays; or there are two that aren't an already supported row vector/column vector pairing (ie two matrices).
* Throw an exception if we have three or more array arguments (after flattening) passed to a supported function until we can identify the abstruse non-euclidian logic behind how Excel handles building, using and presenting those n-dimensional result arrays
* Implement array arguments for the DATE() function so that we can verify that paired arrays/vectors work with functions that support more than 2 arguments
* Implement array arguments for the many of the Math/Trig functions
* Update change log
* Add support for one digit decimals (FORMAT_NUMBER_0)
* Add support for one digit decimals (FORMAT_NUMBER_0, FORMAT_PERCENTAGE_0)
* adding tests for one digit numbers
* cleanup
* add failing test to block merge of this PR until #2555 has been merged
* fix code style
* fix test
* Add unit test for erroneous translations from Russian to English, and a quick/dirty fix
* Additional translation unit tests with accented characters from Spanish, Bulgarian, Czech and Turkish
* Update Change Log
