Transmogrifier

Transmogrifier provides support for building pipelines that turn one thing into another. Specifically, transmogrifier pipelines are used to convert and import legacy content into a Plone site. It provides the tools to construct pipelines from multiple sections, where each section processes the data flowing through the pipe.

A “transmogrifier pipeline” refers to a description of a set of pipe sections, slotted together in a set order. The stated goal is for these sections to transform data and ultimately add content to a Plone site based on this data. Sections deal with tasks such as sourcing the data (from textfiles, databases, etc.) and characterset conversion, through to determining portal type, location and workflow state.

Note that a transmogrifier pipeline can be used to process any number of things, and is not specific to Plone content import. However, it’s original intent is to provide a pluggable way to import legacy content.

3.0.0 (2022-06-29)

• Implement plone/code-analysis-action [ericof]

• Drop support to Plone versions 4.3, 5.0 and 5.1 [ericof]

• Drop support to Python 2.7 and Python 3.6 [ericof]

2.0.0 (2021-09-16)

• Add Python 3 e Plone 5.2 support. [wesleybl, zopyx, cdw9, rpatterson, flipmcf]

• Avoid failures if the id of an item is invalid for Zope. [hvelarde]

1.5.2 (2018-02-27)

• pep 8, utf-8 headers, whitespace strip and sorted imports. [thet]

• Ignore - but log - rare cases of construction errors. Usually this happens for objects you do not want to migrate, but a detailed log entry is written. [sunew]

1.5.1 (2015-11-26)

• Fix broken distribution. [hvelarde]

1.5 (2015-10-22)

• Allow csvsource to read files from GS import context [lentinj]

• Don’t use traversal to avoid problems with acquisition or views. [rpatterson]

• Add csvsource support for taking the filename from an item key. [rpatterson]

• Add csvsource restkey handling for rows with more keys than fieldnames. [rpatterson]

• Add a blueprint for opening and caching URLs with urllib2. [rpatterson]

• Add a source for walking a directory with os.walk. [rpatterson]

• Add support for arbitrary csvsource fmtparam options. [rpatterson]

• Add DEBUG logging for expressions, useful for tracking changes to items as they move through the pipeline. [rpatterson]

• Add an XML walker source section for walking a tree of elements. [rpatterson]

• Add a list source section for adding recursion and/or looping to pipelines. [rpatterson]

• Add pprint support to the logger section, moved from the pprint section used in tests to make it more useful and available in actual pipelines. [rpatterson]

1.4 (2013-04-07)

• Fix the import location of the pagetemplate engine for newer Zope versions. [leorochael]

• Bug fix to load ZCML for GS when Products.GenericSetup is installed. [aclark]

1.3 (2011-03-17)

• Added the GenericSetup import context as an annotation to the transmogrifier. [elro]

• Added a logger to log the value of a particular key for all items. Handy when debugging, you can see which path is failing, and good if you want to show progress in a long import. [regebro]

• Added a breakpoint section to break on a particular expression, which is handy for debugging. [regebro]

1.2 (2010-03-30)

• Bug fix: the constructor promises to encode paths to ASCII, but failed to do so. Thanks to gyst for finding the discrepancy. [mj]

1.1 (2010-03-17)

• Allow the CSV source to load its file from a package as well as from an absolute or relative file path. To load from a package, pass package.name:filename.csv to the filename option. [optilude]

• Add CMF 2.2/Plone 4 compatibility for the content constructor [optilude]

• Use an explicit provides attribute to register the transmogrifier adapter. Fixes the “Missing ‘provides’ attribute” errors when loading with zope.annotation installed. [mj]

• Add a required flag to the content constructor, which causes it to raise a KeyError if the container where to construct the new item doesn’t exist. [regebro]

• Add an optional condition to the manipulator section. [regebro]

1.0 (2009-08-07)

• Initial transmogrifier architecture. [mj]
