I've tracked down bits and pieces here and there, but I'm missing the big picture. For example, this: #+srcname: python2_env #+begin_src emacs-lisp (setq org-babel-python-command "python") (set-face-background 'modeline "#4477aa") #+end_src #+srcname: python3_env #+begin_src emacs-lisp (setq org-babel-python-command "python3") (set-face-background 'modeline "#771944") #+end_src Why is #+srcname being used and not just #+name? I assume these blocks will be called later? I'm also assuming that #+call plays a role, but this page <http://orgmode.org/manual/Evaluating-code-blocks.html> has no examples and confused me. This example <https://lists.gnu.org/archive/html/emacs-orgmode/2010-09/msg00466.html> again uses #+srcname: . . . * Opening > #+srcname: opening > #+begin_src org > Dear Org mode users, > #+end_src . . . * Closing > #+srcname: closing > #+begin_src org > Yours Truly > #+end_src . . . and then . . . \setupdocument{ > to = {% > <<to>>}, . . . > opening = {<<opening>>}, > closing = {<<closing>>} > } I'm guessing the opening and closing are being called. But again, why srcname and not just name? And what if my blocks had been defined somewhere outside of this file?

During development of Babel, source code blocks were originally named using #+srcname:. Later, as other elements gained the ability to be named, it was decided to use a more generic identifier, #+name:. The #+call: syntax is confusing to me, too. I usually put :var arguments in the <arguments> part, non-:var arguments that change what the code block does in <inside header arguments>, and non-:var arguments that affect how the buffer is changed in the <end header arguments>. > > This example > <https://lists.gnu.org/archive/html/emacs-orgmode/2010-09/msg00466.html> again > uses #+srcname: > > . . . > * Opening >> #+srcname: opening >> #+begin_src org >> Dear Org mode users, >> #+end_src > . . . > * Closing >> #+srcname: closing >> #+begin_src org >> Yours Truly >> #+end_src > . . . > and then > > . . . > \setupdocument{ >> to = {% >> <<to>>}, > . . . >> opening = {<<opening>>}, >> closing = {<<closing>>} >> } > > I'm guessing the opening and closing are being called.

Your example expands the source code block. You can get the results of the source code block with <<opening()>>, which I think is what this example might intend. If the blocks are defined outside of the file, then where they are defined is a library of Babel. You'll need to explicitly load them with the org-babel-lob-ingest function. You can have as many libraries of Babel as you want. hth, Tom -- Thomas S. Dye http://www.tsdye.com ^ permalink raw reply [flat|nested] 5+ messages in thread

You can name the file as you wish, and you can have as many libraries of Babel as need be. I have this code in .emacs to load one of my libraries of Babel: (org-babel-lob-ingest "~/org/td-lob.org") After the library has been "ingested" then you can call the named source code blocks it contains, just like you would if they were defined in your working buffer. hth, Tom -- Thomas S.
