Ruby and dot

Hello,

Is there an “official” Ruby/dot package? I can’t find it in the RAA
and searching for “dot” on blade is pointless due to anti-spamming email
address spellings.

dot is part of AT&T’s open source graph drawing software which RDoc uses
to draw class diagrams (see http://www.research.att.com/sw/tools/graphviz/).

Thanks,

You might look at the internals of rdoc… it uses
dot to draw class diagrams if you use the --diagram
option. I haven’t looked at it myself.

All I know.

Look in the RAA for graphr by Robert Feldt, or if you have rapt
just type `rapt install graphr’ and get it installed.

Hey,

rdoc (http://rdoc.sourceforge.net) includes a dot.rb package which
allows you to construct a graph and then write the graph in dot format
out to file. I’ve used it and it’s quite easy to use. I’m not sure if
you can obtain it seperately from rdoc though.

What exactly are you looking for?

In a small example [1], I used Robert Feldt’s GraphR [2]; more links and
info on www.graphviz.org.

In many cases, you can simply generated dot files with Ruby.

That’s the crux of my question…

GraphR is probably it…

It depends on what you’re doing, but in some cases it’s definitely
better to generate the dotfiles directly. You’ll have full controll and
all the features.

Perhaps you might also have a look at RGL (Ruby Graph Library) which also uses dot.rb from rdoc to
draw graphs:

http://www.ruby-lang.org/en/raa-list.rhtml?name=RGL or
http://www.hduchene.de/ruby/rgl/doc/

for drawing/manipulating/plotting graph/images/diagram there is some
options at the RAA under Graphics.
However, (for some reason ?) Graphr and RGL is in RAA under Datastructure.
