Getting Started with Gato

Run Gato (depending on your plattform and how you installed Gato, you may need to type gato and hit return, type Gato.py and hit return at your prompt, double-click Gato.py or drag-and-drop Gato.py over the python interpreter).

You get two windows: The algorithm window (with the menu) shown here after opening an algorithm:

And the graph window shown here after opening a graph.
.

From the File menu in the algorithm window you can open a graph and an algorithm or create an Encapsulated Postscript (EPS) file capturing the contents of 'main' graph window.

Once you have openend an algorithm and a graph, you can use the buttons at the bottom of the algorithm window to control execution:

  • 'Start' starts the execution of the algorithm
  • 'Step' does a single step from one line of the algorithm to the next
  • 'Trace' on a line where a function is called will trace into the function. Only supported in a few places.
  • 'Continue' the algorithm will run and not stop until its done or an breakpoint is encountered.
  • 'Stop' terminates the execution of the algorithm

Lines which are breakpoints are displayed in red. You can toggle breakpoint by simply clicking on the line (even while the algorithm runs).
