I think you stumbled on a "bug" (though probably just more of an oversight). I looked around a bit for the default babel header arguments and think this looks accurate: - http://orgmode.org/manual/System_002dwide-header-arguments.html#System_002dwide-header-arguments This, with nothing set for `:exports something`, the default is `:exports code`. What you did instead is correct -- you want to export results. I get the same behavior: code only with no value set, results with `:exports results` added. To "patch," that page, you would follow the procedure for contributing to Worg: - http://orgmode.org/worg/worg-git.html You submit a key to Bastien, clone Worg, edit the file, and push your changes.
