Hi,
If I have something like
,-------------------------------------------
| #+name: dot-code
| #+begin_src perl :results output :cache no
| print <<END;
| digraph G {
| overlap=false
| "Node\\nA"
| "Node\\nB"
| Core -> "Node\\nA"
| Core -> "Node\\nB"
| }
| END
|
| #+end_src
|
| #+header: :var input=dot-code
| #+header: :file tmp.pdf
| #+header: :cmdline -Kneato -Tpdf
| #+begin_src dot :exports both :cache yes
| $input
| #+end_src
`-------------------------------------------
I get the following error when evaluating the second block:
,-----------------------------------------------------------------
| executing Perl code block (dot-code)...
| "digraph G {
| overlap=false
| \"Node\\nA\"
| \"Node\\nB\"
| Core -> \"Node\\nA\"
| Core -> \"Node\\nB\"
| }
| "
| executing Dot code block...
| replace-regexp-in-string: Invalid use of `\' in replacement text
`-----------------------------------------------------------------
If I paste the output of the first block into its own src block, like
this:
,----------------------------------------
| #+header: :file tmp.pdf
| #+header: :cmdline -Kneato -Tpdf
| #+begin_src dot :exports both :cache no
| digraph G {
| overlap=false
| "Node\nA"
| "Node\nB"
| Core -> "Node\nA"
| Core -> "Node\nB"
| }
| #+end_src
`----------------------------------------
I get no error on execution.
If I replace '\\n' with ' X ', i.e. something without '\', in the first
block, the error seen when using the variable $input does not occur.
I'm using Emacs 23.2.1 and Org 7.8.11. Is this a known issue?
Cheers
Loris
