如何列出模块所依赖的用户创建的python文件？

Question

I am interested in using doit to automate the build process of a python package. If possible, I would like doit to re-execute a task if any of the user-created source files it depends on have changed. From my understanding, the best way to accomplish this would be to use the file_dep key and a list of the dependent source files, however I am having a lot of trouble generating this list.

I've tried using sys.modules and inspect.getmembers() , but these solutions can't deal with import statements that do not import a module, such as from x import Y , which is unfortunately a common occurrence in the package I am developing.

Another route I investigated was to use the snakefood tool, which initially looks like it would do exactly what I wanted, generate a list of file dependencies for every file in a given path. Unfortunately, this tool seems to have limited Python 3 support, making it useless for my package.

Does anyone have any insight into how to get snakefood -like features in Python 3, or is the only option to change all of my source code to only import modules?

Answer 1

doit tutorial itself is about creating a graph of python module imports!

It uses import_deps package, it is similar to snakefood .

Note that for your use-case you will need to modify file_dep itself during Task action's execution. To achieve that you need to pass the task parameter to your action (as described here ).
