I didn't need UML. I didn't need the arrows to go the right way or the right sort of boxes. (I didn't know graphviz / dot well enough to get that right, and didn't want to spend the time looking it up.) \n\nI just wanted to grep the source code for all the *extends* and *implements* statements and to see what it looked like.\n\nHere's how I use it\n\n    cat *pde | egrep 'extends|implements' | javanal.py \u003e test.dot\n    xdot test.dot\n    \nYeah, I'm looking at Processing files. That's why they have the .pde suffix and I'm not using an IDE that already has this built-in.\n\nAlso, my program is small ... only 30 or so classes and interfaces. Big enough to get lost in, but small enough to scroll around a single diagram. Anything larger and you probably want a different tool.\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Finterstar%2Fjavanal","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Finterstar%2Fjavanal","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Finterstar%2Fjavanal/lists"}
