Hi all,
How do I get the org file line numbers in the tangled source? This way error
messages point to the org file.

thanks ...

  Hi,
  
  You can use the :comments header argument to include comments around
  tangled code blocks indicating where the code block lives in the
  original Org file.
  
  See [1] for information on the :comment header argument, and see [2] for
  information on using header arguments in general.

    Yes I am aware of the comments argument but it is not what I was
    referring to. What I want is, if I had the following in a file called
    "Haskell.org" :
    * Root
    Root comment
    #+begin_src haskell :tangle Main.hs
      test = length
      main = print $ test [1,2,3]
    #+end_src
    
    I would like the following output in the tangled file Main.hs:
    
    {-# LINE 4 "Haskell.org" #-}
    test = length
    main = print $ test [1,2,3]
    
    The line that starts with {-# LINE ... #-} is a pragma that tells the
    compiler that this line corresponds to line 4 in Haskell.org and if
    there is an error it will point to that file and not to Main.hs.
    
    Can I take it that this functionality doesn't yet exist?

      Hi,
      
      This isn't the first request for customizable comments in tangled code.
      I've just implemented a first pass at this functionality, the variables
      org-babel-tangle-comment-format-beg and
      org-babel-tangle-comment-format-end now hold simple format string
      specifying how the comments surrounding code blocks should be
      constructed, see their documentation for more info.
      
      As an example, the following specification should yield the results
      you're after
      #+begin_src emacs-lisp :results silent
        (setq org-babel-tangle-comment-format-beg "{-# LINE %start-line \"%file\" #-}"
              org-babel-tangle-comment-format-end ""
              org-babel-tangle-pad-newline)
      #+end_src
      
      Best -- Eric
