Hi, in this e.g: I'm creating a package that holds other packages so it's easily installable 🙂 , the thing is that I need to maintain this manually I'm wondering if is there any way to pass a wildcard in dependencies or any way to search for relevant targets and pass them as dependencies

python_sources(
    name="lib",
    sources=["scripts/*.py"],
    dependencies=[
        f"{base_path}/package1:lib",
        f"{base_path}/package2:lib",
        f"{base_path}/package3:lib",
        f"{base_path}/packageN:lib"
    ],
)

python_sources(
    name="lib",
    sources=["scripts/*.py"],
    dependencies=[
        f"{base_path}/package*:lib", #does not work
    ],
)

no, there are no dynamism to dependencies in BUILD files. However, you can use a generic

target

to avoid duplicating the effort of maintaining that list if you have it in multiple places..

target(
  name="libs",
    dependencies=[
        f"{base_path}/package1:lib",
        f"{base_path}/package2:lib",
        f"{base_path}/package3:lib",
        f"{base_path}/packageN:lib"
    ],
)

python_sources(.., dependencies=[":libs"])

another option is you can potentially reduce the boilerplate by using a function (or as a macro if you need the same thing in more than one BUILD file):

def libs(*names, base_path="src/path/..."):
  for name in names:
    yield f"{base_path}/{name}:lib"

python_sources(.., dependencies=[*libs("package1", "package2", ...)])

any way to list/search the targets in BUILD file?

Yeah, ask this of the parent dir path containing the BUILD file:

pants list the/build/file/is/in/here:

The

:

is like

*

, glob all targets here. The

::

is like

**

, glob all targets here and under recursively.

and if you want to see the field values of them as parsed, including inferred dependencies and such, there’s

pants peek

I need to do this programmatically, so I can calculate the dependencies inside the same directory tree

def search_dependencies(path:str)->list[str]:
    # implementation

python_sources(
    name="lib",
    sources=["scripts/*.py"],
    dependencies=search_dependencies(base_path)
)
