Thanks. Since I'm using a set of patches to MoinMoin itself (not only
in $INSTANCE_HOME) to generate LaTeX, I'm a bit slow to catch up... ;)

You're right. I meant 'attachment:file.html' without the curlies
before 1.7.0 and {{attachment:file.html}} for transcludes with
1.7.X...

What I've done for now is this:

In $INSTANCE_HOME/data/plugin/parser, I've added a file html.py
which contains this:

---------------- BEGIN html.py ------------------------------------------

# -*- coding: iso-8859-1 -*-

Dependencies = []

class Parser:
    """
        Send plain text in a HTML <pre> element.
    """

    extensions = ['.html']
    Dependencies = []

    def __init__(self, raw, request, **kw):
        self.raw = raw
        self.request = request
        self.form = request.form
        self._ = request.getText

    def format(self, formatter):
        """ Send the text. """
        self.request.write(formatter.preformatted(1))
        self.request.write(formatter.text(self.raw.expandtabs()))
        self.request.write(formatter.preformatted(0))

---------------- END html.py ------------------------------------------

It does work quite well...

Yes, of course I did that. But it was useless...

2.5.2

Anyway, using a custom parser for '.html' that renders preformatted
text solved the problem quite nicely. ;)

Thanks again,
