This commit is a big refactor that improves the code organization.
It focuses on how dependencies are injected into the different classes. This is now done via some factories.
Also, the code is now built around entities (data model that only exposes getters and setters), managers (used to manage an entity) and helpers (used by the managers to perform some specific tasks).
The refactoring is not fully complete, as some dependencies are still hidden...
This will improve the management of options and simplify some methods' signatures.
This commit will also help moving the code to a better state regarding Dependency Injection.
Fixes#295
If a row should be written with a custom style, the handling of empty cells should change.
Instead of being skipped entirely, empty cells will be applied the custom style, if this style has custom background color or borders.
If not, then the cell definition can still be skipped.
* Fix#276, some general refinement
* Failing test #267
* Fixed shared border definitions across different styles #267
* Fix finding the correct borderId
This fixes issues when something went wrong on reader/writer init and the developer wants to close the reader/writer.
The file handle may not be defined so we need to add a check for it, before actually using it.
The ZipHelper interface is now more generic and allow single files to be added.
It supports adding uncompressed files (for PHP7+), which is required to have the mime detection magic work with ODS files.
Also fixed a few issues with the created ODS file (thanks to https://odf-validator.rhcloud.com/)
Since cells are referenced by their coordinates (A2, B4...), it is not necessary to write empty cells.
This will reduce the final size of the generated XML and therefore XLSX file.
Added ODS writer
Refactored XLSX writer to abstract some pieces into an abstract multi-sheets writer
Created an abstract style helper
Moved shared components around
Invalid names can also be triggered by:
- character ":"
- single quote at the beginning of the name
- single quote at the end of the name
Introduced a StringHelper, wrapping multibyte strings functions
Based on Excel requirements:
- it should not be blank
- it should not exceed 31 characters
- it should not contain these characters: \ / ? * [ or ]
- it should be unique
Added top level methods on the Writer:
- addRowWithStyle()
- addRowsWithStyle()
Added a style builder, to easily create new styles.
Each writer can specify its own default style and all styles will automatically inherit from it.
For now, the style properties supported are:
- bold
- italic
- underline
- strikethrough
- font size
- font name
- wrap text (alignment)
