Download

You can download a command-line version of Vlad. It has been tested under both Solaris 8 and Mac OS/X. (I have not done this for Windows, yet. If you get it running, please let me know!)

System Requirements

Java 1.5. Vlad is a Java application requiring version 1.5 or later of the JRE.
Graphviz. Vlad uses the Graphviz package from AT&T for graph layout and image generation. Graphviz must be installed in order to run Vlad.

Installation

Install Graphviz, if you don't already have it.
- Un*x versions. WARNING: If you don't want Graphviz files mixing with other stuff, you should unpack the tar file in its own directory.
- Mac OS/X version. Be sure to get the .tgz or .zip version (not .dmg).
Download the Vlad distribution file:
- vlad-Install.jar
Open a terminal window and cd to the directory where you downloaded the jar file. E.g.,
% cd $HOME/Desktop
Run the installer:
% java -jar vlad-Install.jar
The installer pops up a dialog that asks for two pieces of information: the path to the Graphviz bin directory, and the path to the directory where you want Vlad installed.

Enter the two directory paths (either type in or use the file browse buttons), the click "Install VLAD". Note that the directory where you want to install Vlad must already exist. Directory names should not include spaces. Vlad will be installed in a subdirectory named "vlad-version", where "version" is the currect version number.
If the installation is successful, you should see the following dialog:
Test Vlad on the sample. cd to the "vlad-version" subdirectory and type:
% vlad Sample
If you are setting up Vlad as a CGI application, you must also edit the file CGI.defaults, and set the variables to appropriate values.
