Hello, Bastien, Thanks for getting back to me. In ob-core.el, function org-babel-expand-noweb-references, line 2747, there is a 'mapconcat, that is commented as ";; Interpose PREFIX between every line." It prepends the "prefix", that is the content of the block to be expanded from the beginning of the line where a <<noweb>> reference is encountered to the beginning of the reference itself, that is to the first "<".
My point is that this is not the most obvious way to do the expansion. It does work if the "prefix" is a line comment character, similar to C++ "//" However, consider the following example: ``` # -*- mode: org; -*- * test :PROPERTIES: :header-args: :noweb yes :END: #+name: block1 #+begin_src shell printf "test1 \n" printf "test2 \n" printf "test3 \n" #+end_src #+begin_src shell :shebang "#!/bin/chibi-scheme" #<<block1>> <<block1>> #+end_src ``` Expanding this example gives: ``` #printf "test1 \n" #printf "test2 \n" #printf "test3 \n" # printf "test1 \n" #<<block1>> printf "test2 \n" #<<block1>> printf "test3 \n" #<<block1>> ``` Not a very obvious interpretation! At least I would expect the following instead: ``` #printf "test1 \n" printf "test2 \n" printf "test3 \n" printf "test1 \n" printf "test2 \n" printf "test3 \n" ``` Because at least it wouldn't leave anything resembling a "<<noweb>>" block in the expansion result. Thanks for looking at this issue.
