#+TITLE:     Noweb references in LaTeX document
#+DATE:      2012-01-30

* Summary

** Problem

I use 3 chunks of LaTeX code which I wanna insert in a LaTeX document.

While 1 of them is correctly tangled into the LaTeX document, the 2 others
generate errors when C-c C-v C-t'ing:

    "if: reference '<<who' not found in this buffer"

and, if I temporarily replace `<<who()>>' by `<<who>>', I get the next error:

    "if: reference '    <<solde' not found in this buffer"

What I don't understand is that there is no -- sorry, I mean: I don't see --
the difference between the 3 noweb references. They all seem correctly
written...

** Note

Remember that, up to now, such a document *must be first tangled* and then
post-processed via =PDFLaTeX=. It can not be exported directly to PDF/HTML (=args
out of range= error).

* Example

** Part 1
#+name: who
#+begin_src org :results latex
1111ToMe
#+end_src

** Part 2
#+name: before
#+begin_src org :results latex
2222BeforeDate
#+end_src

** Part 3
#+name: solde
#+begin_src org :results latex
3333Rest
#+end_src

** Composed letter
#+begin_src latex :noweb yes :tangle yes
\documentclass{article}
\usepackage[utf8x]{inputenc}
\usepackage[T1]{fontenc}

\begin{document}

\begin{textblock}{85}(98,35)
\titlebox{9.4cm}{Foo}{% HERE 1111 <<<<
<<who()>>
}
\end{textblock}

\begin{textblock}{110}(25,195)
    Some sentence
    <<before()>> \hfill{}% HERE 2222 <<<<
    <<solde()>> EUR% HERE 3333 <<<<
\end{textblock}

\end{document}
#+end_src

Best regards,
  Seb

Currently newlines are allowed in noweb reference names causing the
problems you noticed above.  I've just pushed up a change which
disallows newline characters in noweb references and fixes the odd
behavior you describe.

Best,

If it does not take you too much time, can you enlighten me on the diffs
between the chunks?  Why was it well working for the second one?

References are working well. Thanks a lot!

Though, there is an annoying diff in the tangled LaTeX: the first block gets
an extra blank line (I don't understand why it differs from the others) which
will cause layout problem when compiling the document -- not this one, it's
just an not-so-valid ECM, but real ones...

#+begin_src latex
  \documentclass{article}
  \usepackage[utf8x]{inputenc}
  \usepackage[T1]{fontenc}

  \begin{document}

  \begin{textblock}{85}(98,35)
  \titlebox{9.4cm}{Foo}{% HERE 1111 <<<<
  1111ToMe

  }
  \end{textblock}

  \begin{textblock}{110}(25,195)
      Some sentence
      2222BeforeDate
       \hfill{}% HERE 2222 <<<<
      3333Rest
       EUR% HERE 3333 <<<<
  \end{textblock}

  \end{document}
#+end_src

Best regards,
  Seb

I think you'll find that the asymmetry is due to the placement of your
comment strings which have the <<<< characters, misinterpreted in this
case to indicate the start of a noweb reference...

That must be it. Due to the correct highlighting as comments, it did not occur
to me that the `%<<<<<' I inserted looked like noweb refs...

And Eric's fix does solve this.

This isn't priority anymore: currently, I'm not hit by that bug/feature in the
real file I'm working on.

Thanks for the fix you've readily made available...
