General tools for Plone sites

Project description

General tools modules for Plone.

We don’t claim ultimate Plone wisdom (yet); the main purpose of this package is to factor out functionality from a big monolithic product into packages.

Thus, the purpose of this package (for now) is not to provide new functionality; it is more likely to loose functionality during further development (as parts of it will be forked out into their own packages, or some functionality may even become obsolete because there are better alternatives in standard Plone components).

It is part of the footing of the “Unitracc family” of Plone sites which are maintained by visaplan GmbH, Bochum, Germany.

Some modules of this package still contain some resources (e.g. type names) which are specific to our “Unitracc family” of sites; this is likely to change in future releases.


This add-on can be seen in action at the following sites:

Modules in version 1.1.1:

  • attools module

    several tools for Archetypes-based content

  • brains module

    currently one make_collector function, e.g. for address fields

  • cfg module

    Read “product” configuration, and detect development mode

  • context module

    Several tools for processing the request. Some need some modernization …

  • forms module

    Several tools for forms

  • functions module

    Some functions, e.g. is_uid_shaped

  • log module

    Automatically named loggers

  • mock module

    • a few small classes for use in doctests
    • the same module as
  • mock_cfg module

    A rudimentary mock module for cfg

  • search module

    A few functions to support creation of ZODB catalog search queries (quite proprietary, I’m afraid; might go away in future versions)

  • setup module (since v1.1)

    Functions for use in migration scripts

  • zcmlgen module (since v1.1.1)

    • Generates configure.zcml files, if - changes are detected, and - development mode is active, and - the source is in an development package.


Sorry, we don’t have real user documentation yet.


Since is a package for Plone instances, it is not normally installed using pip; instead, install it by adding it to your buildout:



eggs =

and then running bin/buildout


If you are having issues, please let us know; please use the issue tracker mentioned above.

1.1.3 (2019-01-29)

  • setup.make_renamer(): generated rename function improved: existing positional options default to None; instead of uid, o (object) or brain can be specified (by name).

  • setup.make_query_extractor(), generated extract_query function improved: don’t convert a Language string to a list if it’s value is all

  • zcmlgen module:

    • Bugfix for changes detection
    • If changes are found but disallowed (non-development setup), and if sys.stdout is connected to a terminal, start the debugger

  • Corrections for the documentation
  • (currently) unused dependencies removed [tobiasherp]

1.1.1 (2018-09-27)
