A tool to rewrite parts of template files (DTML, ZPT).

gocept.template_rewrite

A tool to rewrite parts of template files (DTML, ZPT and XPT).

The initial use case is to have a pluggable system to convert Python 2 expressions in templates to Python 3.

This package runs on Python 3.6 up to 3.8.

Requirements

For the rewrite to work properly, it is necessary to have this structure attr="value" for attributes in tags with no whitespaces around the =, as otherwise the values will get lost.

Caveats

• During rewrite double hyphens within HTML-comments are removed as the Chameleon engine in Zope 4 (and the actual specification) is very strict about it.
• The underlying lib2to3 does not take into account, that the cmp function is no longer available in Python 3.
• This tool converts Python 2 to Python 3 - that means the code may not be compatible with Python 2 any more. For these edge cases manual changes are required to make it compatible with both versions.
