[Orgmode] Re: From state table to state diagram
You first need to decide on a syntax: how many cols in the table and what do they mean. A Confluence plugin does that. You may want to check it out for inspiration and nice examples: https://studio.plugins.atlassian.com/wiki/display/GVIZ/Confluence+Graphviz+Plugin https://studio.plugins.atlassian.com/wiki/display/GVIZ/Graph-from-table+Macro Dot is a really simple language, so translating to it should be easy. Eg | state1 | state2 | transition | becomes state1 - state2 [label=transition] ___ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.

Re: [Orgmode] Re: From state table to state diagram
I just started, in another context, to look into radio tables, and I thought - wouldn't this be an option? I mean - putting a radio table into a plantuml block and translating it, should not be to difficult? And it would be perfectly in line with org. The same could be done for graphviz.

Re: [Orgmode] Re: From state table to state diagram
Gary, One other request for you to entertain. When you get into the Python code (I can help with this, if you need it) think about organizing it such that you can use multiple output mechanisms. For example, default it to use dot as you have been talking about but allow for the use of tikz as Erik Fraga mentioned in August. This would imply converting to some intermediate representation from the table form and then passing that data to a dynamically selected back-end output engine. I suggest tikz as an alternative since it can make such beautiful graphs. I haven't made use of babel yet so I don't know all its ins and outs but I expect that there are ways of passing additional information to the language doing the heavy lifting so we could add various output modules...

Re: [Orgmode] Re: From state table to state diagram
Hi
I really like the idea of this conversion from a State Transition Table to a
State Transition Diagram as it is much easier to make a table then a graph.
Unfortunately I don't know enough of python to help here.
Could you please publish your solution here (and on worg) as it would be a
very useful addition to org.
Cheers,
Rainer

Well, wikipedia suggests the following[1] (and goes into further detail
as well[2])
| Current State - | State | State | State |
| Input v| A | B | C |
|--+---+---+---|
| x| B | ... | ... |

'x' then it transitions to State B, and when it receives a 'y' in State
B it transitions to State C.

Okay. What should this python code here do? :) I know, it converts a
table to dot-script, but are there any examples I could look at which
take a table as input and output something (anything), just so I can see
how the python code should expect its input?

library of babel [1] (a collection of generally useful code blocks).
Sure :)

Hi Gary,
The answer is that python receives that as [[1, 2], [3, 4]]. There are a
few ways to arrive at that answer. For your table-to-dot script I
suspect it is going to be easiest to use the :results output header
argument, which means that the result will be the printed output of the
python block (as opposed to...[1]). So using that, one way to see how
python receives its input is:
#+source: table-to-dot
#+begin_src python :var table=state-table :results output
print str(table)
#+end_src
#+results: table-to-dot
: [[1, 2], [3, 4]]
Another way is to place point in the code block and use C-c C-v C-v
`org-babel-expand-src-block'.
Alternatively, you might want to use a session to play around with the
input data structure interactively. In that case, add :session, and
use either C-u C-c C-v C-z or C-u C-c C-v z to bring up the emacs python
session with the input variable pre-loaded.

Yes, that is what I was thinking (but did not want to type on the little on-screen keyboard of my phone...) when I suggested graphviz: dot could be a good intermediate language. Well, maybe it's a bit specific and nobody has done anything so I should look into it on my own :) It is indeed specific but I think there would be some interest in what you manage to concoct so please post it here! If I were to have time to do this right now, I would probably use awk to convert a state transition table to a dot graph representation but only because I'm very comfortable with awk and much less so with emacs lisp... And the ease will depend on the type of transition table you have as the starting point, of course... As an aside, when it comes to actually generating a diagram, I would in practive typically use tikz due to the quality of the graphs that can be achieved. However, it may be harder to do a table \to tikz translation automatically. -- Eric S Fraga GnuPG: 8F5C 279D 3907 E14A 5C29 570D C891 93D8 FFFC F67D ___ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.
