Description Simon Parsons 2012-02-03 17:46:30 CET

I was looking at some of the instructions on the wiki - specifically some of the how-tos - and wondered if the GraphViz extension was available as it's very useful for creating flow charts to visualise procedures.

Is it possible to have this plugin installed??

Simon: In such requests, it's always nice to provide urls, although it's easy to find in this case:

Oliver: I try to keep your mind active by giving you these little extra tasks ;-)
Actually, I must apologise as I completely forgot to include the link!

Imported into Cauldron, please test, so we can backport it and install into our wiki.

The following 5 packages are going to be installed:

- graphviz-2.28.0-4.mga2.x86_64
- lib64cgraph6-2.28.0-4.mga2.x86_64
- lib64gvpr2-2.28.0-4.mga2.x86_64
- mediawiki-graphviz-0.9-1.89857.1.mga2.noarch
- mscgen-0.20-1.mga2.x86_64

4.4MB of additional disk space will be used.

----------

The installation instructions are a incomplete..

To use this extension, you have to add the following three lines to your LocalSettings.php
include("extensions/GraphViz/GraphViz.php"); ->execPath = "/usr/bin/"; ->mscgenPath = "/usr/bin/";

From the extension URL

include("extensions/GraphViz/GraphViz.php"); //includes the extension<br />
$wgGraphVizSettings->execPath = "/path/to/graphviz/"; //Path to the Graphviz Installation
$wgGraphVizSettings->mscgenPath = "/usr/bin/";

It looks like the variables have been stripped out.

Once the correct lines put in LocalSettings.php tested using code borrowed from Simon

<graphviz caption='Inset Assignment Procedure'>

digraph INSETS {

SITE -> "Home Cell"; "Home Cell" -> Prediction; Prediction -> Dominant; Dominant -> "Use in-Cell channels"; "Use in-Cell channels" -> "Check C to I"; Prediction -> Smaller; Smaller -> "Use Insets"; "Use Insets" -> "Check C to I"; "Check C to I" -> "Print Plots";

}

</graphviz>

Produced a flowchart.


Other than the installation instructions this appears to be working fine.

Thanks :)

The variables appear to have been removed from the README.install.urpmi file so it is displaying correctly. They have probably been removed by the build system.

Comment 7 Simon Parsons 2012-02-27 12:59:04 CET

Hi Claire,

Thank you very much!  
I'll have to write a how-to for getting Mediawiki-GraphViz working in Mag2, won't I? ;-)

Simon

Display of php variables in README.install.urpmi fixed.

Comment 11 claire robinson 2012-03-02 18:56:32 CET

Sysadmin.. Does this need an mga1 version before it can be applied to the wiki or can you do so with this mga2?

If mga2 is Ok could this be applied please.

Thankyou :)
