Appy 0.8.5 has been released

Written for Appy by Gaëtan Delannay on 2013-08-12

This is the last release of series 0.8. It is a bugfix release, also including minor improvements, mainly at the gen and px levels. This is the last 'gen' version where ZPTs (Zope Page Templates) will work. They will be replaced with PXs (appy.px=PythonXml) in the next Appy version.

[pod,px] 'loop' variable, available in the pox/px context, allows to know if we are managing an even or odd elem via loop.<elem>.odd and loop.<elem>.even.

[gen]
- Added the posssibility to create a custom widget that displays an icon for generating a doc from a pod field, but with an additional param allowing to customize the pod context.
- Some actions were triggered via icons. That was not explicit enough for basic users. So now, every action is triggerd by a button that displays an icon+a text.
- In the process of migrating from ZPT (Zope Page Templates) to appy.px (Python Xml).
- On Page instances, one may now define a method for conditionnally showing the 'edit' button on 'view' layout.
- An app may now, on its Config class, define a method getHomeObject that must return an object that will be the home object for a given (class of) user(s). This object's menu will appear when the user is consulting a page with no tied menu (like a search for example).
- Moved Appy fields into appy/fields together with their PX.
- Added a validator for String fields, for validating Belgian NISS numbers.
- Replaced, in PXs, function 'img' by function 'url', that returns the URL of an external resource to be included in the XHTML, like an image, a Javascript file or a CSS file.
- Created param config.groupsForGlobalRoles that disables by default creation of a group for every global role.
- On a appy class it is now possible to define a static method 'generateUid' that generates a UID for every instance of this class, instead of using the standard Appy way to produce such UIDs.
- Changed the way to customize the Config in an app.

[px]
- PX is now thread-safe.
- Added the possibility to have several PX actions in the same XHTML tag. If several PX actions are defined, they are evaluated in this order: var, for, if.
- Added tag 'var2', similar to 'var', but that is executed after tags 'for' and 'if'.
- Managed special HTML attributes like 'checked' and 'selected'.
- Better error reporting when encountering a parsing error in a PX.
- Added boolean param 'unicode' that defines if PX result must be unicode or an encoded str.

[shared]
- dav: improved Resource.soap: better handling of HTTP header SOAPAction.
- dav: Upgraded dav.py to use httplib.HTTPConnection instead of httplib.HTTP.
- dav.Resource: allow to retrieve the result encoded or not in utf8.

Appy 0.8.4 has been released

Written for Appy by Gaëtan Delannay on 2013-06-13

pod
- Added the possibility to define several variables, in 'with' statements, separated by ';'.
- Added the possibility, for function 'document', to import, into an ODT result, external documents of various formats: doc, xls, ppt, etc. This new 'ConvertImporter' uses LibreOffice to first convert the doc into PDF, and then uses the PdfImporter to split the PDF into images (one image per page) and include in in the pod result.
- Allowed to call a pod template within another pod template via new POD function 'pod'.
- Improved error handling.
- Bugfix: error when a pod template does not have a 'mimetype' file inside (https://bugs.launchpad.net/bugs/1173009)
- Bugfix: error when parsing some ods pod templates: some cells do not have attribute 'office:value-type' (see bug https://bugs.launchpad.net/bugs/1173301).
- An expression that begins with char ':' is considered XML code that will come into the result unescaped.
- Within the context of a 'for' statement, loop objects now have additional boolean attributes named 'first' and 'last' that allow to know if the currently walked element is, respectively, the first of the last element of the whole list.
- Added params 'pageBreakBefore' and 'pageBreakAfter' to OdtImporter and PodImporter.
- Updated 'print' statements throughout Appy code, in order to be Python3x as well as Python2x-compliant. But Python3x support is not yet complete.
- Added new method 'pageBreak' allowing to insert a page break via a note 'do xxx from pageBreak()'
- Line breaks which are found within pod expression results are converted to odf line-breaks into the pod result.

gen
- gen now integrates ckeditor 4.1.
- Integrated ckeditor inline editing via boolean parameter field.inlineEdit.
- icons.pt can now be configured even for anonymous users.
- Added tool.sendMail as an easy access method for function appy.gen.mail.sendMail.
- A Page instance that does not have sub-pages does not show the portlet.
- Added field appyclass.breadcrumb, allowing to show/hide the breadcrumb when displaying instances of this class
- Added field appyclass.resultMode, allowing to choose between 'list' or 'grid' mode (previously, only list mode was enabled) when showing instances of this class as a result of some query.
- appyclass.getIcons now receives the nav param, in case one wants to reproduce, on an icon or a picture, the link to the element. For example, on a artist's site that presents its artworks, getIcons can be used to create a clickable link to a small version of the artwork, that leads to the full-size picture.
- Bugfix: sort references.
- Allow to show transitions on 'view' and/or 'result' layout types.
- UI improvements.
- Added the possibility to define dict someClass.styles (with, currently, a single entry 'title'), allowing to specify alternative CSS classes for class-related elements (here, 'title' allows to define an alternative CSS class for the link allowing to click on some instance of the class on a query or ref.
- Added a basic integration of gen applications with Google Analytics.
- Bugfix in the query engine.
- Bugfix: do not show the Calendar widget (search and edit layouts) if field.calendar is False.
- Bugfix in the start and end dates for the Calendar widget.
- Added Config.discreetLogin allowing to put a discreet link on the main page for logging in, instead of the login form in the central strip, for sites where logged users do not represent the majority of visitors (only some admins).
- Corrected Zope index type for Date fields.
- wrapper.appyUser returns the admin if the user is 'System Processes', the virtual user that runs when Zope is starting.
- Added the possibility, for an admin, to unlock a page that was locked for too long by some user.
- Improvement in the management of Unauthorized exceptions.
- Added attributes 'created' and 'modified', now accessible on Appy wrappers.
- Added method AbstractWrapper.countRef that allows to count the number of objects tied to a given object via a Ref field whose name is given as method param.
- Replaced attributes tool.enableAdvancedSearchForX by klass.searchAdvanced.show. Obsolete fields 'enableAdvancedSearchX' are not generated anymore on the tool.
- Added a mechanism for caching method calls that are performed several times for displaying a single ui page (ie: field.show methods).
- Bugfix in the way to index text fields containing line breaks.

bin
- Added a new script odfGrep.py that allows to search for some pattern within odt and ods files.
- Added script bin/checklo.py to check connection to LibreOffice.

px
- First version of a new template engine Python-XML, sharing the pod roots.

***pod now works with ODS (spreadsheet) templates! ***

Here is the full change log.

pod
- Added the possibility to use POD with ODS (Calc) templates. Integration with gen (Pod field).
- Bugfix for https://bugs.launchpad.net/appy/+bug/1083533 (thanks Gauthier): management of HTML entities with the standard Python SAX parser expatreader.
- Bugfix while generating filenames for files included into pod results.
- Changed the way pod results are re-zipped, in order to be compliant with section 17.4 of the OpenDocument format specification (bug https://bugs.launchpad.net/appy/+bug/1101237).
- Use, when available, Python's uuid module to generate images and file names to be included in pod results.
- Performance improvement: stop computing tag names, create a dict of precomputed tags before starting parsing.
- Bugfix: import several times an image from the same URL.

gen
- Bugfix: it is now possible to generate indexes on back references.
- Added the possibility to span widgets on several columns on the search screen (param Field.scolspan).
- Added config param 'enableSessionTimeout' for enabling/disabling session timeout (disabled by default).
- Bugfix: generate i18n label even for transitions for which show is False, because the label will be used within object's history.
- Allow to display, in history, differences between successive versions of XHTML fields via appy.shared.diff.HtmlDiff (which was not integrated to appy.gen until now). Improved rendering of XHTML fields.
- Allow to show the cumulative differences performed on historized String fields with format=String.XHTML.
- One can now specify a different source language for every translation.
- field.history can now be a method. This way, historization can be enabled/disabled, field by field, according to any custom condition.

- Added, on edit.pt (the unique Appy HTML form) a handler window.onbeforeunload to warn the user that data can be lost or a lock can stay on the object.
- Stop using param 'cmp' in method [].sort (deprecated in Python3). Used para 'key' instead.
- Wrapper.reindex: allow to specify attribute 'fields' containing the list of fields that must be reindexed. If not given, all object fields are reindexed.
- Improved search abilities.
- Added params Type.swidth and Type.sheight to allow for different sizes for the search widgets.
- Bugfix while generating the Translation class (page 'main' was not viewable because of field 'trToTool' for which page.show was False for an unknown reason).
- Added a link to the home page for anonymous users; resized fields 'login' and 'password'.
- Bugfixes with IE8 and JS function 'getElementsByName'.

Appy 0.8.2 has been released

Written for Appy by Gaëtan Delannay on 2012-12-07

Here's what has changed.

appy.pod
- xhtml2odt: allow, when converting tables, to take into account attributes 'width' of tds.

appy.shared
- xml_parser.XmlParser: added param 'raiseOnError' allowing to raise or not an exception when a SAX fatal parsing error is encountered.
- Bugfix for https://bugs.launchpad.net/appy/+bug/1083533 (thanks Gauthier).

appy.gen
- Added some layouts for Ref fields in Ref.wLayouts and Ref.wdLayouts.
- Added a new, simpler way of defining auto-references (=Ref fields that refer to the class containing the field), via method appy.gen.autoref.
- Stop catching exceptions raised by Actions (so a partial action can't be committed anymore).
- Cleaner and more robust approach when using Zope database indexes.
- ckeditor now works with IE.
- Now it is possible to index and search Ref fields.
- Added a i18n label used for the title of web pages and added a default favicon and the possibility to override it.
- Bugfix in the standard banner for RTL languages.
- Added some default page and field layouts.
- Added the possiblity to extract in a clean way text from XHTML field values.
- Fine-tuned indexing machinery with more accurate text extraction from text and xhtml fields.
- Added a new calendar field, allowing to add a single (typed) event by day.
- Added missing i18n in Ref field.
- Calendar: added the possibility in some calendar to view events from another calendar.
- Optimized Ref: do not ajax-call the Ref view macro when displaying a complete page.
- Added Ref.changeOrder to enable/disable (independently from write permission) the possibility to sort or change order of referred objects.
- Improved performance of the Ref field and added an icon for dissociating referred objects.
- Calendar field: added the possibility to define eventTypes dynamically: eventTypes can therefore be anything, ie object UIDs.

- Added param Search.default allowing to define a default Search. The default search, if present, will be triggered when clicking on the main link for a class, instead of the query that collects all instances of this class.
- appy.gen.Type: removed 3 obsolete params: 'index', 'editDefault' and 'optional'. For achieving the same result than using 'editDefault', one may define 'by hand' an attribute on the Tool for storing the editable default value, and define, on the appropriate field in param 'default', a method that returns the value of the tool attribute.

- For Type.shownInfo and tool.resultColumnsXXX, added the possibility to define the name, width and alignment of every column (=notion of 'column layout').
- Added an index 'Modified' on every object (it represents the date of the last modification).
- Removed obsolete workflow-related code.
- Removed attributes Tool.showAllStatesInPhaseForXXX.
- Changed the way to display the object's current state in the UI.
