Changelog
=========
0.4.17 (2016-03-22)
-------------------
- Added constant CLASS_TO_LAST_CHILDREN_NUMBER_OF_CHARS_DEFAULT to define the
default number of characters to take into account while marking last tags
in xhtml.addClassToLastChildren. This way it can be used in other packages.
[gbastien]
- Fixed xhtml.imagesToPath to handle image src using 'resolveuid' correctly.
[gbastien]
0.4.16 (2016-03-14)
-------------------
- Bugfix in xhtml.storeExternalImagesLocally if downloaded external image has
no 'Content-Disposition' header.
[gbastien]
0.4.15 (2016-03-14)
-------------------
- Added helper to be able to easily test appy.pod rendering by loading a full
HTML content to any content (AT or DX) by specifying a RichText field_name.
[gbastien]
- Added method xhtml.imagesToPath that turns the src of images used in a xhtml
content from an 'http' or equivalent path to the absolute path on the FileSystem
to the .blob image file.
[gbastien]
- Added method xhtml.storeExternalImagesLocally that will ensure that externally
referenced images are downloaded, stored locally and xhtmlContent is adapted
accordingly.
[gbastien]
0.4.14 (2016-02-25)
-------------------
- Added methods cache.get_cachekey_volatile and
cache.invalidate_cachekey_volatile_for to be used with methods using
decorator @ram.cache. This is meant for long living cached methods that are
invalidated manually. get_cachekey_volatile will be used in the method
cachekey and invalidate_cachekey_volatile_for will be used to invalidate the
cachekey.
[gbastien]
- Add a function to generate a barcode with zint : #13100.
[mpeeters]
- Removed initialize() call from __init__, no need to be considered
as a Zope2 product.
[gbastien]
0.4.13 (2016-01-22)
-------------------
- Use safe_unicode() instead of unicode(), especially in xhtml.markEmptyTags
to avoid UnicideDecode errors.
[gbastien]
0.4.12 (2016-01-21)
-------------------
- Added test when an uid (path) is no more in the portal_catalog,
it does not break catalog.addOrUpdateColumns.
[gbastien]
- In xhtml.xhtmlContentIsEmpty, do no more consider tag children in _isEmpty,
a tag rendering nothing (text_content().strip() is empty) will be considered empty.
[gbastien]
0.4.11 (2015-11-12)
-------------------
- Added 'cache.cleanRamCache' method that will invalidateAll ram.cache.
[gbastien]
0.4.10 (2015-08-21)
-------------------
- Add get_environment method and test.
[bsuttor]
- is_develop_environment method is true if global environment variable 'ENV' is equal to 'dev'.
[bsuttor]
- Added 'cache' module with helper methods 'cleanVocabularyCacheFor' that will clean
instance.memoize cache defined on a named vocabulary and 'cleanRamCacheFor' that
will clean ram.cache defined on a given method.
[gbastien]
0.4.9 (2015-04-21)
------------------
- In xhtml.addClassToLastChildren, do not define an empty class attribute. Indeed, not
managed tags were decorated with a 'class=""' attribute, this is no more the case.
[gbastien]
0.4.8 (2015-04-20)
------------------
- Manage every text formatting tags in xhtml.addClassToLastChildren and
do not break on unknwon tags.
[gbastien]
- Replace special characters by corresponding HTML entity in xhtml.addClassToLastChildren
so rendered content still contains original HTML entities. This avoid HTML entities being
rendered as UTF-8 characters and some weirdly recognized (" ").
[gbastien]
0.4.7 (2015-03-06)
------------------
- Adapted method xhtml.addClassToLastChildren to mark parent tag containing unhandled tags.
[gbastien]
0.4.6 (2015-02-26)
------------------
- Added method markEmptyTags that will mark empty tags of a given
xhtmlContent with a specific CSS class.
[gbastien]
- Removed method security.call_as_super_user as we will rely on
plone.api.env.adopt_roles to execute some methods as super user.
[gbastien]
0.4.5 (2015-02-05)
------------------
- Added method to test if the buildout is in development mode (IS_DEV_ENV=True).
[sgeulette]
- Added method to generate a password following criterias.
[sgeulette]
0.4.4 (2015-01-29)
------------------
- Make it possible to pass specific class by tag to hxtml.addClassToLastChildren,
this way, a specific class can be set depending on the node tag.
[gbastien]
0.4.3 (2015-01-20)
------------------
- Added method addClassToLastChildren that will add a specific class attribute
to last tags of a given xhtmlContent.
[gbastien]
0.4.2 (2014-09-19)
------------------
- Do not consider xhtmlContent to easily empty : xhtmlContent is empty if it does not produce
text, does not have attributes and does not have children.
[gbastien]
- Use method xhtmlContentIsEmpty in method removeBlanks to avoid duplicating code and logic.
[gbastien]
0.4.1 (2014-09-11)
------------------
- Corrected bug in 'removeBlanks' that removed children of an empty parent tag, that leaded
to removal of complex trees like <u><li>My text</li><li>My second text</li></ul>.
[gbastien]
0.3 (2014-09-04)
----------------
- Corrected bug in 'xhtmlContentIsEmpty' that did not managed correctly complex HTML tree.
We use now lxml method 'text_content' to check if a HTML structure will render something or not.
[gbastien]
0.2 (2014-08-27)
----------------
- Added xhtml.py module with helper methods for XHTML content :
- 'removeBlanks' that will remove blank lines of a given xhtmlContent;
- 'xhtmlContentIsEmpty' that will check if given xhtmlContent will produce something when rendered.
[gbastien]
0.1 (2014-08-18)
----------------
- Initial release.
