Bugs/Feature Requests

Existing bugs and feature requests for GraphvizPlugin are here.

If you have any issues, create a new ticket. Be sure to mention which version of Trac and which version of the plugin you're using. If the version number ends with '...dev', then please also specify the changeset number corresponding to the version you're using.

Requirements

The programs from http://www.graphviz.org.

Installation

See source:graphvizplugin/0.10/README.txt for details on installing the plugin on Trac 0.10.

See source:graphvizplugin/0.11/README.txt for details on installing the plugin on Trac 0.11.

After installing, don't forget to enable the plugin in your trac.ini, the usual way:

[components]
...
graphviz.* = enabled
...

Download

Download the zipped source from here. Note that this contains everything regarding the Graphviz plugin including tagged releases and branches. The 0.10 directory contains the latest released version of the code for Trac 0.10 and the 0.11 directory contains the latest code for Trac 0.11.

  • download latest stable version (0.7.5) for Trac 0.11
  • download latest version for Trac 0.10

That version has some trouble with rsvg support for creating anti-aliased images. The upcoming version contains a few related fixes:

  • download latest unstable version (0.7.6dev) for Trac 0.11

If you want to have anti-aliased images, it might be a better option anyway to get/build a recent version of graphviz tools, which support producing anti-aliased images directly (through pangocairo support).

Source

You can check out the source for GraphvizPlugin from Subversion at http://trac-hacks.org/svn/graphvizplugin.

Example

{{{
#!graphviz
digraph G {Hello->World->Graphviz->Rules}
}}}

would produce an image like:

Sample outout from the graphviz plugin, produced with graphviz-2.20.3 with pangocairo support

Note that you can insert TracLinks like this:

{{{
#!graphviz
  digraph G {
    rankdir = "LR"
    GraphvizPlugin [ URL=GraphvizPlugin ]
    Trac [ 
      URL="http://trac.edgewall.org/"   
      fontcolor=red
    ]
    GraphvizPlugin -> Trac
    }
}}}

This produces an image like this, but with the nodes are clickable, unlike here:

second example, this time with colour and TracLinks, also produced with graphviz-2.20.3 on Linux
