Comments in org babel clojure blocks are not tangled out. Let us take an example org file with the following contents:- This org file contains only two source blocks and a total of ten lines. > #+begin_src clojure :noweb-ref "Define a constant" > (def e 2.72) ;;This is a comment on a line of its own > (def pi 3.14) ;;This is a comment not on a line of its own > #+end_src The following block will be tangled > #+begin_src clojure :noweb yes :tangle ./output.clj > <> > #+end_src When I tangle the above file, the contents of the output.clj file are:- > (def e 2.72) > (def pi 3.14) ;;This is a comment not on a line of its own *The comment that was on a line of its own is missing from the tangled output.* Was able to reproduce on both emacs 29.3.50 and 29.4 on Ubuntu 22.04 LTS Both were started using *emacs -Q* and then evaluating *(require 'ob-clojure)* as the only line of config.
