It gets awkward when the defined name is for an actual range rather than for an individual named cell; because we need to manipulate the stack when that happens.
The code is ugly, and this is a rather simplistic approach, but it works as long as the named range is a cell, a cell range, or even a "chained" range - it won't work if we have union or intersection operators in the defined range - but it does provide formula support that never existed before.
The code could stil do with some cleaning up, and better optimisation for memory usage; but all tests are passing... that's for full multi-level sorting (including direction), and allowing for correct sorting of sting/numeric datatypes.
* Eliminate Most Scrutinizer Problems in Test Suite
Mostly minor code changes, with some annotations.
* Missed 2 php-cs-fixer Problems
They should be fixed now.
These changes have already been implemented twice, and been regressed twice. I'll try once more (with a different approach), then give up ...
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 mostly adds annotations or updates doc-blocks. Only 2 members have changes to executable code, and these are very minor - BitWise and Writer/Xlsx. For test members, all baseline errors are deleted and the code is fixed. Php7 and Php8 both report no errors with this configuration.
The new array tests for IMCSC fail on my system because of a rounding error in the 14th (!) decimal position. This is not a real failure. Change the test to use only the first 8 decimal positions.
* 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
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
* Implementation of the SEQUENCE() Excel365 function
Note that the Calculation Engine does not yet support the Spill operator, or spilling functions
* Handle the use-case of step = 0; and tests for exception handling for invalid arguments
* Update Change Log
* Xlsx Reader Merge Range For Entire Column(s) or Row(s)
Fix#2501. Merge range can be supplied as entire rows or columns, e.g. `1:1` or `A:C`. PhpSpreadsheet is expecting a row and a column to be specified for both parts of the range, and fails when the unexpected format shows up.
The code to clear cells within the merge range is very inefficient in terms of both memory and time, especially when the range is large (e.g. for an entire row or column). More efficient code is substituted. It is possible that we can get even more efficient by deleting the cleared cells rather than setting them to null. However, that needs more research, and there is no reason to delay this fix while I am researching.
When Xlsx Writer encounters a null cell, it writes it to the output file. For cell merges (especially involving whole rows or columns), this results in a lot of useless output. It is changed to skip the output of null cells when (a) the cell style matches its row's style, or (b) the row style is not specified and the cell style matches its column's style.
* Scrutinizer
See if these changes appease it.
* Improved CellIterators
Finally figured out how to improve efficiency here, meaning that there is no longer a reason to change Writer/Xlsx, so restore that.
* No Change for CellIterator
I had thought a change was needed for CellIterator, but it isn't.
