# Generate a list of included dependencies
sfood -i example-project > /tmp/out.deps

# Get dependant filepath from each dependency, sort and get unique
cat /tmp/out.deps | \ 
    grep -v test | \
    cut -d"'" -f8 | \ 
    sort | \
    uniq > /tmp/required.txt

# Find all modules in our project
find example-project -name '*.py' | \
    grep -v "__init__.py" | \
    grep -v "test" | \
    sort > /tmp/modules.txt
    
# Compare the two, and cleanup
diff tmp/modules.py tmp/required.py | grep '<' | cut -d' ' -f2

Nice

Suggestions:

• You can combine the two greps into grep -v -e "__init__.py" -e "test"
• You can use CWD=$(pwd) to get the current working directoy and and use that instead of "example-project" as the starting point
• You don't actually clean up, you may want to use TMP_DIR="/tmp/${CWD}/" as in "${TMP_DIR}/out.deps" and then add at the end of the code rm -r "${TMP_DIR}"
