From a76629a565920c3506f7046cc15d27ad01b8bd47 Mon Sep 17 00:00:00 2001 From: Eric Schulte Date: Mon, 12 Jul 2010 10:42:59 -0700 Subject: [PATCH] org-exp: raise an error when trying to export code blocks w/o languages * lisp/ob.el (org-babel-get-src-block-info): ensure that we don't match (and return info for) source blocks without a language * lisp/org-exp.el (org-export-replace-src-segments-and-examples): updated source code block regexp so that the presence of a language can be explicitly checked. Also now raising an error when a source block does not have a language. --- lisp/ob.el | 3 ++- lisp/org-exp.el | 30 ++++++++++++++++++++---------- 2 files changed, 22 insertions(+), 11 deletions(-) diff --git a/lisp/ob.el b/lisp/ob.el index 7b7be3d..d94cc06 100644 --- a/lisp/ob.el +++ b/lisp/ob.el @@ -143,7 +143,8 @@ added to the header-arguments-alist."
