Re: [Orgmode] Need help on org-exp-blocks and dot

[Bryan Emrys]

Thank you Eric and Erik for the incredibly quick troubleshooting. I updated
.emacs with the setenv command suggested by Eric, restarted emacs and
everything now works as expected.

Re: [Orgmode] Need help on org-exp-blocks and dot

[Eric Schulte]

back when I had to use a mac, I would just symlink paths into standard
locations, e.g.

  ln -s /opt/local/bin/dot /usr/bin/dot

Maybe not the most elegant solution, but it works reliably

To do this the *right* way you can update the PATH environment variable
*within* Emacs by doing something like the following

(setenv "PATH" (concat "/opt/local/bin/:" (getenv "PATH")))

How are you echoing path, starting up a terminal, or within
Emacs M-x shell?

What if you try M-x getenv  PATH  in Emacs?

Absolutely.



On the mac, dot is in /opt/local/bin/dot
My .emacs file has: (setq load-path (cons "/opt/local/bin"
load-path))


That won't add anything to your shell's path, it's just where Emacs
looks for code to load.


I can certainly just open a terminal window and run dot from
the command line.


Can you grep your shell startup files and find out which one adds
/opt/local/bin to the path?

Hmm. Pathname issue?

On the mac, dot is in /opt/local/bin/dot
My .emacs file has: (setq load-path (cons "/opt/local/bin" load-path))

Thanks for any further suggestions.

Re: [Orgmode] Need help on org-exp-blocks and dot

[Eric Schulte]

Hi Bryan,

For generating dot graphics from Org-mode it is now suggested to use a
normal code block rather than org-exp-blocks, for example the following
should generate a graph when pressing C-c C-c on the block, and on
export should include the resulting graph rather than the code block.

from http://www.graphviz.org/Gallery/directed/fsm.gv.txt
#+begin_src dot :file fsa.png :exports results
  digraph finite_state_machine {
  rankdir=LR;
  size="8,5"
  node [shape = doublecircle]; LR_0 LR_3 LR_4 LR_8;
  node [shape = circle];
  LR_0 -> LR_2 [ label = "SS(B)" ];
  LR_0 -> LR_1 [ label = "SS(S)" ];
  LR_1 -> LR_3 [ label = "S($end)" ];
  LR_2 -> LR_6 [ label = "SS(b)" ];
  LR_2 -> LR_5 [ label = "SS(a)" ];
  LR_2 -> LR_4 [ label = "S(A)" ];
  LR_5 -> LR_7 [ label = "S(b)" ];
  LR_5 -> LR_5 [ label = "S(a)" ];
  LR_6 -> LR_6 [ label = "S(b)" ];
  LR_6 -> LR_5 [ label = "S(a)" ];
  LR_7 -> LR_8 [ label = "S(b)" ];
  LR_7 -> LR_5 [ label = "S(a)" ];
  LR_8 -> LR_6 [ label = "S(b)" ];
  LR_8 -> LR_5 [ label = "S(a)" ];
  }
#+end_src

[Orgmode] Need help on org-exp-blocks and dot

[Bryan Emrys]

Hello. Trying to use org-exp-blocks with dot to export a graphic in
generated html file. Works on linux box.

However, on a mac box everything except the graph is generated. Instead of
pulling in the graphic, it just prints dot_somehashednumber.png. As far as I
can tell, that png is not generated anywhere and left in a file system
either.

Dot works standalone from a terminal window. Paths seem to be right and
emacs isn't complaining about loading org-exp-blocks.

The emacs version on the mac is 23.1.1. I have (require 'org-exp-blocks) in
the .emacs file.

Any suggestions on what to look for next?

Thanks,

Bryan
