In version 7.4, org-export-html-preamble and org-export-html-postamble could
be set to the name of a function that was passed an option plist. This
appears to no longer be supported in 7.5.
I used this functionality when publishing to generate a preamble and
postamble to integrate the generated pages into my website, which included a
common page layout, header bar, and footer. I was able to define options in
org-export-inbuffer-options-extra, define values for these options in a .org
file, and incorporate them into the preamble via the option plist passed to
the org-export-html-preamble function.
Is there another way in version 7.5 that I can generate custom preambles and
postambles incorporating variables from each file at the time of publishing?
With much thanks,
Bill
