Re: Macros and Caching

Hello,

I think I can give you the answer for the first question of
yours.

I think you already notice that you can enable/disable the caching
in your moin_config.py by adding the line:

  caching_formats = ["text_html"] # for enabling, default in config.py
  caching_formats = []            # for disabling

This fact is almost the answer.

If you remove "text_html" from caching_formats in your
macro, moin doesn't use caching.

For example:

    # first disable caching if enabled
    caching_flag = False
    if "text_html" in config.caching_formats:
        caching_flag = True
        config.caching_formats.remove("text_html")

    ##### your code here
    ##### blah, blah, blah,

    # enable caching if necessary
    if caching_flag:
        config.caching_formats.append("text_html")


I am not sure you are reading moin-user list, but I am the
one who send a patch about Include macro a couple of days
ago and complained about caching didn't go well with this
macro.

Now I got the solution and I am sharing this with you.

Hope this helps.
