Document Templating Markup Language (DTML)

Project description Current version on PyPI Supported Python versions


This package implements the original Document Templating Markup Language (DTML). It uses custom SGML tags to implement simple programmatic features, such as variable replacement, conditional logic and loops.

Inside Zope environments page templates and TAL have superseded DTML for most use cases.


4.6 (2023-11-13)

  • Add official support for Python 3.12.

4.5 (2023-09-18)

  • Add preliminary support for Python 3.12rc1.

  • Be more resilient on sorting if the getter returns None. (#72)

4.4 (2022-01-12)

  • Drop support for Python 3.6.

4.3 (2022-12-21)

  • Fix restructured-text format specification. Tests were silently skipped.

4.2 (2022-12-16)

  • Fix insidious buildout configuration bug for tests against Zope 4.

  • Add support for Python 3.11.

4.1 (2022-09-20)

  • Set the tree-s cookie for dtml-tree tags with SameSite=Lax. The tree tag never set this attribute. That causes modern browsers to show warnings in the browser console and break tree displays in the future. See for information about the SameSite cookie attribute and why its handling in browsers is changing.

  • Add support for Python 3.10.

  • Drop support for Python 3.5.

4.0 (2020-11-12)

  • Make ustr.ustr Python 3 compatible (Zope#921)

  • Add support for Python 3.9

  • Restore sql_quote behavior of always returning native strings (#54)

  • Fix broken tree tag (#52)

  • Drop support for Python 2.

  • Eventually drop BBB code leading to a deprecation warning in version 3.2+. (#42)

  • Update isort to version 5.

3.2.2 (2020-02-04)

  • de-fang sql_quote even more as quoting is too database-specific. (#48)

3.2.1 (2020-02-03)

  • prevent a really strange AccessControl test failure when running Zope’s alltests script by importing deprecated names from zope.sequencesort.ssort instead of sequence/ in sequence/

3.2 (2020-02-03)

  • no longer escape double quotes in sql_quote - that breaks PostgreSQL (#48)

  • Added DeprecationWarnings for all deprecated files and names (#42)

  • Import sorting done like Zope itself

  • Applied extended linting configuration similar to Zope’s own

3.1 (2020-01-31)

  • Escape more characters in sql_quote. Taken over from PloneHotfix20200121.

3.1b2 (2019-05-16)

  • Fix broken handling of SyntaxError under Python 3

3.1b1 (2019-05-13)

  • Don’t call HTTPExceptions that are looked up in TemplateDicts

3.0 (2019-05-09)

Changes since 2.13.2:

Breaking changes

  • Replace C code with a pure-Python implementation.

  • Remove VSEval module. Please use DT_Util.EVal now.

  • Remove DTtestExpr module. It contained nothing useful.

  • Remove support for string exceptions in <dtml-except>. (#29)


  • Add support for Python 3.5, 3.6, 3.7, 3.8.

  • Make the rendering encoding configurable to fix rendering on Zope 4. (#43)

  • Add __contains__ support to DocumentTemplate.TemplateDict.

Bug fixes

  • Only decode input in html_quote when needed under Python 3 (Products.PythonScripts#28 <>_)

  • Make sure all JSON-serialized data is text data and not bytes. (#45)

  • Fix regression with exception handling in <dtml-except> with Python 2. (#25)

  • Stabilized TreeTag rendering for objects without _p_oid values. (#26)

  • Fix bugs with <dtml-in>:

    • Raise proper error if prefix is not simple.

    • Fix complex multisort in Python 3.

    • Fix iteration over list of tuples in Python 3.

  • Ensure html_quote is being applied to content.

2.13.2 (2011-12-12)

  • Restrict the available functions in DocumentTemplate.sequence to public API’s of zope.sequencesort.

2.13.1 (2010-07-15)

  • LP #143273: Enable the dtml-var modifiers url_quote, url_unquote, url_quote_plus and url_unquote_plus to handle unicode strings.
