Comment #7 on issue 2103 by asmeurer: fix sympy's internal dependencies
http://code.google.com/p/sympy/issues/detail?id=2103
I played with this a little more, and got a graph of only the top level
directories. Here's the command I used to create the dot file (there's
also some stuff to remove things that just clutter the graph):
sfood sympy/ | sfood-cluster `LS -1 sympy | xargs -L 1 echo "sympy/"| tr
-d " "` | GREP -E "((.*?sympy.*?,.*sympy.*?), (.*?(sympy|
None).*?,.*?(sympy|None).*?))" | GREP -v "'sympy'" | GREP -v "conftest" |
GREP -v "abc.py" | sfood-graph > sympy-dependencies-graph.dot
Then supposedly
sympy-dependencies-graph.dot | dot -Tps | pstopdf -i | xargf acroread
will create a graph from it (I personally just used the Mac OS X GUI
Graphviz program). I've attached both.
What can be learned from this. Well, the modules that have no arrows
pointing to them, or only arrows from unimportant modules do not need to be
imported automatically. This can be misleading, as this includes
*everything*, including imports within functions and imports in tests.
Hence, e.g., printing appears to require everything, but actually it only
imports the various things if they are used in the first place. The
command above could easily be extended to skip tests.
By the way, is there an actual issue here?
