I have many files each with as many as 60 tables that are generated using ob -rec. So that the tables are not evaluated during export it is convenient for me to set a buffer wide #+PROPERTY: header-args :eval never-export. On other hand, each file may also include, under a sub-tree latex source code blocks for signature lines, letter heads, etc. In another sub-tree, called correspondence, those source code blocks are called using :noweb yes, such as #+begin_src latex :noweb yes <> #+end_src \begin{center} \today \end{center} [Body of letter] #+begin_src latex :noweb yes <> #+end_src If I include in the correspondence sub-tree :PROPERTIES: :header-args: :eval yes :END: the results are a complete letter, i.e. letterhead followed by the body and then signature line. If I do not include the ":eval yes" property in the sub-tree, only the body of the letter results, as expected. So after all that, here are some questions: Is ":eval yes" officially allowed and, if so, why is it not documented? Should it be? May its use be inferred from other examples such as those from :cache or colnames? I found the following discussion, but it is fairly old: https://emacs.stackexchange.com/questions/2945/org-babel-eval-with-no-confirmation-is-explicit-eval-yes Charlie Millar
