* 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.
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
* Split Information functions into a dedicated class and namespace and categorise as Value or Error
* Refactor all error functions into the new ExcelError class
* isFormula Referencing Sheet With Space in Title
See issue #2304. User sets a cell to `ISFORMULA(cell)`, where `cell` exists on a sheet whose title contains a space, and receives an error. Coordinates are not being passed correctly to Functions::isFormula; in particular, the sheet name is not enclosed in apostrophes, e.g. `Sheet Name!A1` rather than `'Sheet Name'!A1`. (Note that sheet name was not specified in Cell; PhpSpreadsheet adds it before calling isFormula.) Sheets without embedded spaces (or other non-word characters) are handled correctly with or without apostrophes, but spaces require surrounding apostrophes.
As part of this investigation, I determined that Excel handles defined names and cell ranges in ISFORMULA (subject to spills), and that PhpSpreadsheet does not. It is changed to handle them. In the absence of spill support, it will use only the first cell in the range.
Existing tests for ISFORMULA used mocking unneccesarily. They are moved to a separate test member, and mocking is no longer used.
* PhpUnit and Jpgraph
35_Char_render.php had previously been a problem only for PHP8+. It is now a problem for PHP7.4, and will therefore be skipped all the time.
For each of the files in this PR, one or more statements can pass a null to string functions like strlower. This is deprecated in PHP8.1, and, when deprecated messages are enabled, causes many tests to error out. In every case, use coercion to pass null string rather than null.
This request does not change any source code, only tests.
For a change on which I was working, a test passed when run on its own,
but failed when run as part of the full test suite. It turned out that
an existing test had changed a static value,
thousands separator in this case, and failed to restore it.
The test turned out to be AdvancedBinderTest.
The search for the offending test was more difficult than it should have
been because 26 test scripts which had nothing to do with thousands
separator nevertheless changed that value. They all changed
decimal separator, currency code, and compatibility mode as well,
again for no reason. I changed all of those to eliminate those operations.
I changed the following tests, which actually do change the static
properties identified above for a reason, to restore them as part of teardown.
- CalculationTest sets compatibilityMode and locale
- DayTest sets compatibilityMode, returnDateType, and excelCalendar
- CountTest sets compatibilityMode
- FunctionsTest sets compatibilityMode and returnDateType
- AdvancedValueBinderTest sets currencyCode, decimalSeparator, thousandsSeparator
- StringHelperTest sets currencyCode, decimalSeparator, thousandsSeparator
- NumberFormatTest sets currencyCode, decimalSeparator, thousandsSeparator
- HtmlNumberFormatTest sets currencyCode, decimalSeparator, thousandsSeparator
- Fix ISFORMULA() function to work with a cell reference to another worksheet
- Added calculation engine support for the new functions that were added in MS Excel 2013 and MS Excel 2016
- Text Functions
- CONCAT() Synonym for CONCATENATE()
- NUMBERVALUE() Converts text to a number, in a locale-independent way
- UNICHAR() Synonym for CHAR() in PHPSpreadsheet, which has always used UTF-8 internally
- UNIORD() Synonym for ORD() in PHPSpreadsheet, which has always used UTF-8 internally
- TEXTJOIN() Joins together two or more text strings, separated by a delimiter
- Logical Functions
- XOR() Returns a logical Exclusive Or of all arguments
- Date/Time Functions
- ISOWEEKNUM() Returns the ISO 8601 week number of the year for a given date
- Lookup and Reference Functions
- FORMULATEXT() Returns a formula as a string
- Engineering Functions
- ERF.PRECISE() Returns the error function integrated between 0 and a supplied limit
- ERFC.PRECISE() Synonym for ERFC
- Math and Trig Functions
- SEC() Returns the secant of an angle
- SECH() Returns the hyperbolic secant of an angle
- CSC() Returns the cosecant of an angle
- CSCH() Returns the hyperbolic cosecant of an angle
- COT() Returns the cotangent of an angle
- COTH() Returns the hyperbolic cotangent of an angle
- ACOT() Returns the cotangent of an angle
- ACOTH() Returns the hyperbolic cotangent of an angle
- Financial Functions
- PDURATION() Calculates the number of periods required for an investment to reach a specified value
- RRI() Calculates the interest rate required for an investment to grow to a specified future value
Conditional operators in the selection parameter of COUNTIF
functions were not being parsed properly, causing evaluations
of formulae with such functions to sometimes fail.
Fixes#526Closes#528
This change adds support for newer functions that are prefixed
by _xlfn. (#356). The calculation engine has been updated to
recognise these as functions, and drop the _xlfn. part.
It also add a couple of the new functions such as STDEV.S/P,
MODE.SNGL, ISFORMULA.
Fixes#356Closes#390
Because even if it doesn't make a difference in practice, it is
technically more correct to call static methods statically. It
also better advertise that those methods can be used from any context.
