Each directory contains a small example highlighting a particular name binding pattern. The examples use Python syntax, but do not necessarily implement Python semantics. Each directory contains a stack-graphs.tsg file that describes at the top what behavior it implements, and a tests directory showcasing the behavior.

Running the examples requires the Python grammar to be available. This can be installed (in this directory) by executing:

./bootstrap

Run the tests for an example by executing:

./run EXAMPLE_DIR

or, from within the example's directory:

../run

To render HTML visualizations of the stack graphs for the tests in an example, add the -V flag to run.

Print the parse tree of an example file by executing:

./parse EXAMPLE_FILE

The following examples are available:

• Nested scoping
• Sequential definitions
• Modules and imports
