If BIFF5 excel 95 file doesn't have codepage record, the default codepage CP1252 is used and can't be change.
That causes to problems with decoding cyrillic text.
If row or column dimensions are accessed, then HTML writer would
still generate lots of empty cells, to show nothing at all. This
now ignore row and column dimensions to only output cell that
actually exists (even if those cells are empty).
Fixes#1235Close#1537
* Corrected date time detection
German and Swiss ZIP codes (special formats provided in German Excel versions) were detected as date time value, because the regular expression for date time formats falsely matched their formats ("\C\H\-00000" and "\D-00000").
* Xls Writer - Correct Timestamp Bug, Improve Coverage
I believe that Xls Writer is 100% covered now.
The Xls Writer sets its timestamp incorrectly. The problem is actually
in Shared/Ole::localDateToOLE, which converts its timestamp using
gmmktime; mktime is correct. If I save a file at 3:00 p.m. in San Francisco,
this bug means the time is actually recorded as 3:00 p.m. UTC.
A consequence of this is that if you use Phpspreadsheet to read the
file and save it as a new Xls, the creation timestamp goes further
and further back in time with each generation (or further forward
if east of Greenwich). One of the tests added confirms that
the creation timestamp is consistent with the start and end times
of the test.
The major change in coverage is adding tests to save GIF and BMP
images, which aren't supported in Xls, but are converted to PNG
in the PhpSpreadsheet code.
Fixes a bug when doing a HLOOKUP on a single row.
```php
<?php
require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Spreadsheet;
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
/**
* Single row.
*/
$singleRow = "=HLOOKUP(10, {5, 10, 15}, 1, 0)";
$sheet->getCell('A1')->setValue($singleRow);
// Should echo 10, but echos '#N/A' and some PHP notices and warnings.
echo $sheet->getCell('A1')->getCalculatedValue() . PHP_EOL;
/**
* Multiple rows.
*/
$multipleRows = "=HLOOKUP(10, {5, 10, 15; 20, 25, 30}, 1, 0)";
$sheet->getCell('A2')->setValue($multipleRows);
// Should echo: 10 and also does.
echo $sheet->getCell('A2')->getCalculatedValue() . PHP_EOL;
```

This problem is the same as #1238, which was resolved by #1239.
For that issue, the fix was to check in one place whether
$this->mapCellXfIndex[$xfIndex] was set before using it.
The sample spreadsheet supplied as a description for this
problem had exactly the same problem in 2 other places in the code.
In addition, there were 7 other places in the code where that
particular item was used unchecked. This fix corrects all 9 locations.
The spreadsheet supplied with the problem is used as the basis
for some new tests, which particularly test column dimensions
and styles, the problems involved in this case.
#1495 reports that ActiveSheet can change when calculation
involves jumping around between sheets.
Save index before calculation, restore after, add test.
* Improve Coverage for Sylk
I believe that both BaseReader and Sylk Reader are now 100% covered.
Documentation available for this format is sparse.
It was always incomplete, and in some cases inaccurate.
My goal was to use PhpSpreadsheet to load the test file,
save it as Xlsx, and visually compare the two, then add a test
loaded with assertions. Cell values and calculated values,
and border styles were generally handled pretty well without changes.
Other types of styling were not handled so well. I added a few cells
to exercise some previously uncovered code.
Sylk files must be ASCII. I have deprecated the use of the
setEncoding and getEncoding functions, which had no test cases.
* Improve Coverage for Gnumeric
I believe that both BaseReader and Gnumeric Reader are now 100% covered.
My goal was to use PhpSpreadsheet to load the test file,
save it as Xlsx, and visually compare the two, then add a test
loaded with assertions. Results were generally pretty good,
but there were no tests with assertions. I added a few cells
to exercise some previously uncovered code. Code was extensively
refactored; logic changes are noted below.
Code allowed for specifying document properties in an old format.
I considered removing that, but I found the original spec at
http://www.jfree.org/jworkbook/download/gnumeric-xml.pdf
This allowed me to create an old file, which was not handled
correctly because of namespace differences. The code was corrected
to allow for this difference.
Added support for textRotation.
Mapping of fill types was not correct.
* PHP7.2 Error
One assertion failed under PHP7.2. Apparently there was some change in
the handling of SimpleXMLElement between 7.2 and 7.3. Casting to string
before use eliminates the problem.
* Scrutinizer Recommendations
All minor, solved (hopefully) mostly by casts.
* One Last Scrutinizer Fix
... I hope.
* Fix For #1509
User expected no CSV enclosures after $writer->setEnclosure(''),
which had been changed to be consistent with $reader->setEnclosure('').
Writer will now omit enclosures after code above; no change to Reader.
Tests have been added for this condition.
* Add Option to Write CSV Enclosure Only When Required
Allowing the user to specify no enclosure when writing a CSV can lead to
a situation where PhpSpreadsheet (likewise Excel) will not read the
resulting file as intended, e.g. if any cell contains a delimiter character.
This is demonstrated in new test TestBadReread.
No existing setting will rectify this situation.
A better choice would be to add an option to write the enclosure
only when it is needed, which is what Excel does. The RFC4180 spec at
https://tools.ietf.org/html/rfc4180
states when it is needed - when the cell contains the delimiter,
or the enclosure, or a newline.
New test TestGoodReread demonstrates that the file is read as intended.
The documentation has been updated to describe the new function,
and to change the write example where the enclosure is set to null.
* Scrutinizer Suggestions
3 minor changes, all in tests.
This problem is that ZipStream, in contrast to ZipArchive,
is saving 2 files with the same path. I have opened an issue with
ZipStream, who agree that this appears to be a bug.
For the case in question, PhpSpreadsheet is attempting to save
a file with the same path twice (and unexpectedly succeeding)
because of a clone operation. This fix attempts to rectify the problem
by keeping track of all the paths being saved in the zip file,
and not attempting to save any duplicate paths.
The problem case attempted to save printersettings1.bin twice,
but there are other possible exposures, e.g. by cloning a sheet
with a drawing.The new test cases clone an existing sample which
has both printer settings and drawings.
Replace default gridlines with different style. Usable in PDF
as well as HTML.
Documentation mentioned use of setUseBOM with Html, but that method
does not exist, and there is no real reason to support it.
Removed it from documentation.
* Improved handling of named ranges, although there are still some issues (names ranges using a union type with an overlap don't handle the overlap twice, which as the MS Excel approach to set overlaps as opposed to the mathematical approach which only applies overlap values once)
* Fix tests that misused space and comma as simple separators in cell ranges
We give users the ability to edit Html/Pdf, but it's a little cumbersome
to use the edited Html for an Html file, and difficult to use it
for a Pdf. I believe we could make it fairly painless in both cases
by allowing the user to set a callback to edit the generated Html.
This can be accomplished with fewer than a dozen lines of very simple code.
I think this would be easier than grabbing the Html in pieces,
editing it, and reassembling it. I think it would also be simpler
than an alternative I considered, namely the addition of a new method
(e.g. saveEditedHtml) to each of the Html and Pdf writers.
One edit that users might like to make when editing html is to add
fallback fonts, something that is not currently available in
PhpSpreadsheet, and might be difficult to add. A natural extension to
that idea would be the use of webfonts, something which is guaranteed
difficult to add. See samples/Basic/17b_Html for an example of this.
None of the PDF writers support webfonts yet. That doesn't mean they
won't do so in future, but, for now, samples/Pdf/21a_Pdf is a prosaic
example of something you could do with this callback. In fact, this
opens the door to letting the user replace the entire body with data
of their choosing, effectively allowing PhpSpreadsheet (where you can
set things like paper size and orientation) to be used as a front-end to
the Pdf processor without the user having to be be overly familiar with
the vagaries of the PDF processor. I think this is actually a pretty
nice idea. YMMV. See samples/Basic/21b_Pdf for an example.
