I'm trying to draw some silly diagrams with dot, based on code stolen from
tutorials here:
http://irreal.org/blog/?p=2866
and here:
http://orgmode.org/worg/org-tutorials/org-dot-diagrams.html
The code won't work, though I can generate the diagram using a somewhat
clumsier method from here:
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-dot.html
Here are my two tables, one for nodes and one for edges (the real ones are
longer, with something like 30 or 40 nodes):
#+name: students-table
| *node* | *label* | *shape* | *fillcolor* |
|--------+-----------+---------+-------------|
| a | Omar | ellipse | green |
| b | Hindia | ellipse | orange |
| c | Yuvrai | ellipse | purple |
#+name: students-graph
| a | b |
| a | c |
| b | c |
I can generate my table using these two code blocks:
#+name: make-dot
#+BEGIN_SRC emacs-lisp :var table=students-table graph=students-graph
:results output :exports none
(mapcar #'(lambda (x)
(princ (format "%s [label=\"%s\" shape=%s style=\"filled\"
fillcolor=\"%s\"];\n"
(car x) (second x) (nth 2 x) (nth 3 x) )))
table)
(mapcar #'(lambda (x)
(princ (format "%s -- %s;\n"
(first x) (second x)))) graph)
#+END_SRC
#+BEGIN_SRC dot :file Images/test-dot.png :var input=make-dot :exports
results
graph {
rankdir=TB
$input
}
#+END_SRC
I would, however, like to avoid the clumsy intermediate step and use
something like this instead:
#+name: graph-from-tables
#+HEADER: :var nodes=students-table graph=students-graph horiz='t
#+BEGIN_SRC emacs-lisp :file ~/example-diagram.png :colnames yes :exports
results
(org-babel-execute:dot
(concat
"graph {\n"
(when horiz "rankdir=LR;\n") ;up-down or left-right
(mapconcat
(lambda (x)
(format "%s [label=\"%s\" shape=%s style=\"filled\"
fillcolor=\"%s\"]"
(car x)
(nth 1 x)
(if (string= "" (nth 2 x)) "box" (nth 2 x))
(if (string= "" (nth 3 x)) "none" (nth 3 x))
)) nodes "\n")
"\n"
(mapconcat
(lambda (x)
(format "%s -- %s;"
(car x) (nth 1 x) )) graph "\n")
"}\n") params)
#+END_SRC
However, this just creates a file ~/example-diagram.png whose content is
"nil%". I'm not sure how to debug the problem. Any suggestions? Does this
code work for you guys? I am using an uptodate arch linux, emacs 25, and a
recent graphviz.
thanks as always for the help.
Also -- WISHLIST: instead of a manually-entered list of edges, I'd like to
randomly create a random set of connections between the nodes. I can
easily create a list of nodes:
(let ((names () ))
(dolist (x nodes)
(push (nth 1 x ) names)
)
... do some stuff here)
but generating a list of unique edges -- that is, node pairs where
(a . b) and (b . a) are considered equivalent -- is somewhat beyond me.
Again, many thanks,
Matt

There are a couple of problems, one minor (the :colnames yes part
truncates the graph so you have only two edges), and one major: the
"params" argument is not defined.
When a dot source block is passed to org-babel-execute:dot, the params
argument I get [fn:1] is:
((:comments . #1="") (:shebang . #1#) (:cache . "no") (:padline . #1#)
(:noweb . "no") (:tangle . "no") (:exports . "results")
(:results . "file replace") (:session . "none") (:hlines . "no")
(:file . "Images/foobar.png") (:result-type . value)
(:result-params "file" "replace") (:rowname-names) (:colname-names))
So I tried passing it to org-babel-execute:dot and somewhat
to my surprise it worked [fn:2] - try evaluating the following in your
*scratch* buffer (make sure there is an Images subdir under the
current directory of that buffer):
--8<---------------cut here---------------start------------->8---
(org-babel-execute:dot
"graph {
rankdir=LR;
a [label=\"Omar\" shape=ellipse style=\"filled\" fillcolor=\"green\"]
b [label=\"Hindia\" shape=ellipse style=\"filled\" fillcolor=\"orange\"]
c [label=\"Yuvrai\" shape=ellipse style=\"filled\" fillcolor=\"purple\"]
a -- b;
a -- c;
b -- c;
}
"
'((:comments . #1="") (:shebang . #1#) (:cache . "no") (:padline . #1#)
(:noweb . "no") (:tangle . "no") (:exports . "results")
(:results . "file replace") (:session . "none") (:hlines . "no")
(:file . "Images/foobar.png") (:result-type . value)
(:result-params "file" "replace") (:rowname-names) (:colname-names)))
--8<---------------cut here---------------end--------------->8---
But I would hardly call this method less clumsy than your earlier
attempt.
Footnotes:
[fn:1] I made a simple dot source block with your graph
#+BEGIN_SRC dot :file Images/foobar.png
graph {
rankdir=LR;
a [label="Omar" shape=ellipse style="filled" fillcolor="green"]
b [label="Hindia" shape=ellipse style="filled" fillcolor="orange"]
c [label="Yuvrai" shape=ellipse style="filled" fillcolor="purple"]
a -- b;
a -- c;
b -- c;
}
#+END_SRC
and instrumented org-babel-execute:dot under edebug - when I executed the code
block, the debugger kicked in when the function got called and I could
get the "params" argument.
[fn:2] I thought the #1 and #1# constructs (which I don't understand at
all) would make it blow up.

> Many thanks, Nick, and especially to the pointer to edebug (so obvious
once you say it!). With my original code, I stepped through the whole
function and I can't quite understand why it's not working. The code block
text is generated as expected, but somehow it's not getting written, or
perhaps not executed by dot, as hoped. Here is the debugging output:

"orange") ("c" "Yuvrai" "ellipse" "purple"))))

Just a quick addendum. Pausing during debugging and running
(with-temp-file in-file )
(org-babel-eval
"dot /tmp/babel-2749DTL/dot-2749Nkt -Tpng -o
/home/matt/example-diagram.png" "")
from a scratch buffer also works. So I am really confused -- maybe there
is something wrong with ob-dot itself?

hmm. It looks like maybe I didn't -- I confess I'd forgotten about this
old email. Looks like I just generated the diagram from a scratch buffer,
as described in my email. Sorry I didn't get further!

No problems.
I've determined tonight that it was working fine in org 8.2.10, but
the problem you report is in org 8.3.1. There are many changes in
ob-core.el, but little in ob-dot.el or ob-eval.el, so further
investigation is required. I'll continue plugging. I really like
building graphs using dot through org-mode, so I'd love to see this
fixed (e.g. I had to revert to LibreOffice Draw today!).
Thanks,
Éibhear
