I had hoped to develop a filter that would allow me to put something like: 
language=python
parameters: :var data=tbl-data
in front of the block for an html export. I tried following the example here: http://orgmode.org/manual/Advanced-configuration.html at the end, by defining a derived mode. However, it does not appear that the information is kept in the parse tree. (src-block (:language python :switches nil :parameters nil :begin 536 :end 578 :number-lines nil :preserve-indent t :retain-labels t :use-labels t :label-fmt nil :hiddenp nil :value print data :post-blank 2 :post-affiliated 536 :parent #4)) although if I look at the element at point, it seems to be there: (src-block (:language python :switches nil :parameters :var data=tbl-data :begin 536 :end 629 :number-lines nil :preserve-indent t :retain-labels t :use-labels t :label-fmt nil :hiddenp nil :value print data (princ (org-element-at-point)) I am not sure why the :end values are not the same though. Here is what I was trying to use: #+BEGIN_SRC emacs-lisp (defun my-src-block (src-block contents info) (message "start-block\n\n%s\n\nend-block" info) (concat "
"
   (format "[language: %s]" (org-element-property :language src-block))
   (format "\nparameters: %s" (org-element-property :parameters src-block))
   "

" (org-export-format-code-default src-block info))) (org-export-define-derived-backend 'my-html 'html :translate-alist '((src-block . my-src-block))) (org-export-to-file 'my-html "custom-src-table-export.html") (browse-url "custom-src-table-export.html") #+END_SRC There are two issues with this block: 1. All parameters are listed as nil 2. the code is not syntax highlighted in html at all. Any suggestions on how to achieve this? I also want to insert tablenames, and if the src-block is named to put the name above the block (for extra gravy, a hyperlink from :var to the source ;). thanks, -- ----------------------------------- John Kitchin http://kitchingroup.cheme.cmu.edu
