Is there a good way to see orphaned files in pants? basically files that only end up in lib and test targets but are never put into a binary

Interesting. I think you can pipe together a few commands to get this. Something like this to first get all your package targets, then to find their dependees + those package targets

./pants filter --target-type=pex_binary,python_distribution,archive :: | xargs ./pants dependees --transitive --closed

Now, find the set difference of something like

./pants list ::

or

./pants filter --targget-type=python_library ::

, then subtract the previous result. Then on those remaining targets,

./pants filedeps

to see which files they correspond to

comm

is magic for stuff like this.

Personally, I do the very verbose thing of using Python and

subprocess.run()

+ its

set

data type, but yeah

comm

allows you to stick to bash

Oh that's awesome. I'll give that a shot.

./pants dependees

is one of my fav features of Pants for that exact reason, I love deleting code

Would pants consider adding a

test

argument to the targets that are

python_library

that would block them from being imported into nontest root targets? It could make this a little easier. I'm currently adding

tags = {'test-only'}

to those libs.

Probably before adding that would be adding more general support for visibility. Pants atm has no support for limiting imports, and you could for example import files from a

python_tests

target from a

python_library

target

I would love that feature. I find it very helpful for enforcing what the directory structure means.
