This tool filters the output of agda --dependency-graph by

• removing library modules
• removing direct dependencies where there's also an indirect dependency

The tool assumes that you start it in the base directory of your Agda codebase.

1. Create a dependency graph.

   agda -i . -i /some/library/src -i /another/library/src MainModule.agda --dependency-graph big.dot
   

   The big.dot graph will contain modules from all three search path components.

2. Filter the dependency graph.

   filter-agda-dependency-graph < big.dot > small.dot
   

   The small.dot will only contain modules from . but not from /some/library/src or /another/library/src.

3. Layout the graph.

   dot -Tpdf small.dot > small.pdf
