0.20 (2019-07-19)

  • In xhtml.storeImagesLocally, do not break when a resolveuid is found but it does not find the image. This can be the case when copy/pasting HTML code from another instance or so. [gbastien]

0.16 (2019-01-31)

  • Added appy.pod usecase to show problems with table optimization if <td> has a defined size. [gbastien]

0.14 (2018-10-22)

  • Improved content create to avoid creating object when defined id already exists. [sgeulette]
  • Added methods content.uuidsToCatalogBrains and content.uuidsToObjects. [gbastien]

  • Added parameter raise_on_errors to content.validate_fields to raise a ValueError when errors are found instead simply returning it. [gbastien]

0.13 (2018-08-31)

  • Added content.get_schema_fields to get schema fields (behaviors included by default). [sgeulette]
  • Pep8 on imports. [sgeulette]
  • Added appy.pod usecase for lists containing tables. [bleybaert]
  • Added dependency on Plone in setup.py. [gbastien]

  • Improved annotation code [sgeulette]

  • Fixed bug in catalog.addOrUpdateIndexes where a new index was not reindexed if it was added together with an already existing index. [gbastien]
  • Fixed bug in xhtml.storeImagesLocally when img uses a resolveuid and starts with the portal_url (this is the case when using uploadimage plugin in collective.ckeditor), it raised a NotFound error. [gbastien]
  • In xhtml.storeImagesLocally, keep the scale at the end of the URL using resolveuid (like resolveuid/content_uid/image_preview). [gbastien]
  • Use PyPDF2 instead deprecated pyPdf to insert barcode into PDF. This solves ValueError: invalid literal for int() with base 10: ‘’. [gbastien]

0.9 (2017-11-27)

  • Added appy.pod usecase for complex styles start/end on same paragraph. [gbastien]
  • Do not break in xhtml.storeImagesLocally when no <img> src found. [gbastien]

0.5 (2017-08-30)

  • Added method to safe encode string. [sgeulette]
  • appy.pod usecase : table using width of 0px. [gbastien]
  • In content.validate_fields, added special bypass to avoid failing validation for Choice field that is required=False and for which given value is None. Validation fails because None not in vocabulary but it is nevertheless a correct value as it is managed by the widget while added thru the UI. [gbastien]
  • Added JS fix to be able to print <fieldset> on several pages in Firefox, see https://bugzilla.mozilla.org/show_bug.cgi?id=471015. This makes it necessary to add a default profile to add the JS resource ++resource++imio.helpers/helpers.js. [gbastien]

  • Added ‘path’ module with method ‘path_to_package’ that will return the absolute FS path to a given package. An extra ‘filepart’ can be provided to complete the returned path. This is useful to get a template in a ‘browser/template’ folder for example. [gbastien]

0.4.19 (2016-09-26)

  • Do not pretty_print HTML returned by lxml.html.tostring or it can leads to weird behaviors like extra blank space in case we have nested <span> tags. ‘pretty_print’ is now a parameter to relevant methods and is False by default [gbastien]

  • Added default views for Dexterity content and container that display fields in a table with widget label and the left and widget value on the right. The view for container also includes an asynchronous folder_listing that lists contained elements. Taken from imio.project.core [gbastien]

0.4.18 (2016-06-17)

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]

0.4.11 (2015-11-12)

  • Added ‘cache.cleanRamCache’ method that will invalidateAll ram.cache. [gbastien]

0.4.10 (2015-08-21)

  • 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]

  • 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 (“&nbsp;”). [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 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;
