Subject: [Zope] HowTo Render txt-Files with LocalFS in PythonScript?
the content is returned but without rendering (as expected).
Does anybody know how to get the rendering done?
in globals which import HTMLFile you can also import HTML which takes a string as an argument. It can then render the text as if it was a normal HTMLFile.

like::

    # the normal way
    index_html = HTMLFile('path/to/file', globals())

    # the other way
    aText = open('path/to/file', 'r').read()
    index_html = HTML(aText)

I hope this is of some help.

if you want to render an arbitrary textfile selected dynamically, this would probably work (untested):

    def fileRender(self, filename):
        aText = open(filename', 'r').read() # get the text
        theDtmlFile = HTML(aText) # create the page
        return theDtmlFile(self, self.REQUEST) # render it

But my guess is that it can be pretty expensive to create a "HTML" object as the dtml will probably be parsed every time. So perhaps you should make some kind of dict to put the pages into. Like::

    class HtmlTxtFile:

        def updateFiles(self):
            pages = {}
            for file in textFiles:
                f = open(file, 'r')
                aText = f.read()
                key = file[file.rfind('/')+1:-len('.txt')]
                pages[key] = HTML(aText)
                f.close()
            self._pages = pages

        def __getattr__(self, attr):
            return self._pages.get(attr)(self, self.REQUEST)
