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 1.4. Vlad is a Java application requiring version 1.4 or later.
Graphviz. Vlad uses the Graphviz package from AT&T for graph layout and image generation. Graphviz must be installed in order to run Vlad.
Standard Un*x tools: bash, tar, gunzip (or gzip or zcat).

Un*x and Mac OS/X 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 to the directory where you want to install it. Here is the file:
- vlad-1.02.tar.gz
Open a terminal window and cd to that directory. E.g.,
% cd $HOME/Desktop
Uncompress the file. (Note: this may have already been done for you by your browser.) E.g.,
% gunzip vlad-1.02.tar.gz
Extract the contents of the tar file. E.g.,
% tar xvf vlad-1.02.tar
The previous step created a directory tree rooted at the current directory. Cd to the top level.
% cd vlad-1.02
Run the Install script, giving it the path to the Graphviz installation directory. (If the path contains spaces, you must enclose it in quotes.) E.g.,
% ./Install "$HOME/Desktop/Graphviz 1.13 (v16)"
This completes the installation. If you move the either the Vlad or Graphviz directories, you must rerun Install.
You should now be able to run the example.
% ./vlad Sample
