* 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.

* Fix Issue 1441 (isDateTime and Formulas)
When you have a date-field which is a formula, isDateTime returns false.
https://github.com/PHPOffice/PhpSpreadsheet/issues/1441
Report makes sense; fixed as suggested. Also fixed a few minor
related issues, and added tests so that Shared/Date and Shared/TimeZone
are now completely covered.
Date/setDefaultTimeZone and TimeZone/setTimeZone were not consistent
about what to do in event of failure - return false or throw.
They will now both return false, which is what Date's function
said it would do in its doc block anyhow. Date/validateTimeZone will
continue to throw; it was protected, but was never called outside
Date, so I changed it to private.
TimeZone/getTimeZoneAdjustment checked for 'UST' when it probably
meant 'UTC', and, as it turns out, the check is not even needed.
The most serious problem was that TimeZone/validateTimeZone does not
check the backwards-compatible time zones. The timezone project
aggressively, and very controversially, "demotes" timezones;
such timezones eventually wind up in the PHP backwards-compatible list.
We want to make sure to check that list so that our applications do not
break when this happens.
No code changes. The tests in all of these scripts write to at least
one temporary file, which is then read and not used again. The file
should be deleted to avoid filling up the disk system.
File author erroneously assumed that backslash was used to escape
quotes in CSV; in fact, doubling the quote is used for escape.
The test still worked, but mainly because the content of the cell
with the escape wasn't tested. The file is now fixed, and
a new test added.
This test changes directory then performs an assertion.
No problem if the assertion succeeds. I was a little concerned about
what would happen if the assertion fails, leaving us in the
new directory. So I have changed test to use setUp/tearDown
to ensure that we end up where we started.
While investigating something else in Shared, I noticed that CodePage
had poor test coverage and a high complexity rating. This change
addresses both; Scrutinizer would love it, although its interface on
GitHub seems broken at the moment (all PRs show "Waiting for External
Code Coverage").
