System-wide header arguments

System-wide header arguments

System-wide values of header arguments can be specified by adapting the org-babel-default-header-args variable:

:session    => "none"
:results    => "replace"
:exports    => "code"
:cache      => "no"
:noweb      => "no"

For example, the following example could be used to set the default value of :noweb header arguments to yes. This would have the effect of expanding :noweb references by default when evaluating source code blocks.

(setq org-babel-default-header-args
      (cons '(:noweb . "yes")
            (assq-delete-all :noweb org-babel-default-header-args)))
