Control characters in cell values are automatically escaped without
the need to excplicitly call `StringHelper::buildCharacterSets()` beforehand.
Fixes#212
The static variable $imageCounter previously had a constant value of 0 throughout the program as it was never being modified, because it was commented out by mistake.
Now it increments every time a new drawing is being instantiated.
This also fixed a problem when multiple images of same name in the same worksheet are incorrectly displayed.

As described in http://interoperability.blob.core.windows.net/files/MS-XLS/[MS-XLS].pdf
a relative column reference can be between -255 +255 and not -127 + 127, the column
index should be read as a signed int16.

Array keys used for styling have been standardized for a more coherent experience.
It now uses the same wording and casing as the getter and setter methods.
Closes#189
Add option to suppress validation of sheet titles
Based on a "lowest common denominator" approach to compatibility,
we will continue to enforce a 31-character limit for sheet titles.
However, this limit should not be enforced when loading an existing
file.
Added a new optional parameter to Worksheet::setTitle() and
Worksheet::setCodeName() to suppress validation and massaging,
based on the premise that existing files should be given a
best-effort approach to loading and parsing. Unfortunately, it's
not possible with the current architecture to prevent users from
making use of this functionality, aside from with a strongly-worded
warning.
Added test coverage. I didn't see any existing unit tests of the
Worksheet class, so I created a new test to cover these methods.
Fixes#176
Fixes the PHP 7.1 bug reported over at PHPOffice/PHPExcel#1110
The behavior should not change since the default value used should behave the same way as the string value in earlier PHP versions.
Fixes a return type in the doc block of IReader.
Closes#165
We used to type hint against IWriter for writer part parent, but this
was not respected in writer part who often coded against the implementation
instead of the interface. With this change we make it a requirement for
writer parts to use their respective writer implementation instead of an
interface. This give legitimate access to all `BaseWriter` methods amongst
other things.
Having default values made it harder for end-user to figure out whether
it the arguement had to be supplied or not. Ommitting the argument may
lead to hard to debug issues, and is overall not a good idea.
Closes#110
In some exotic environnement (IBM AIX) it may happens that `//TRANSLIT` is not supported. In that case iconv would return false. We can easily identify the case and fallback on mbstring instead. That should give correct result.
Closes#135Closes#136
This is a hard limit of the BIFF format that cannot be worked around,
so it is best to throw exceptions than silently discard data or generate
corrupted files.
This drop a lot of non-core features code and delegate their maintainance
to third parties. Also it open the door to any missing implementation
out of the box, such as Redis for the moment.
Finally this consistently enforce a constraint where there can be one and
only one active cell at any point in time in code. This used to be true for
non-default implementation of cache, but it was not true for default
implementation where all cells were kept in-memory and thus were never
detached from their worksheet and thus were all kept functionnal at any
point in time.
This inconsistency of behavior between in-memory and off-memory could
lead to bugs when changing cache system if the end-user code was badly
written. Now end-user will never be able to write buggy code in the first
place, avoiding future headache when introducing caching.
Closes#3
We use to write the wrong property to file, leading to a warning
in PHP 7.1 since the `switch` never matched anything and the variable
was left as a string instead of as an int.
