is there a way to filter output of

./pants list ::

based on target type? For example, I want to get only the python libraries using something like

./pants list --type=python_library ::

. The only thing I could only find in the docs was something like this:

Copy code

# find external dependecies
./pants dependencies --type=3rdparty <lib-target>

found this in the cli. don't know if it is the correct solution.

Copy code

./pants list :: | xargs ./pants filter --filter-target-type=python_library

although this does not work for 3rdparty dependencies

This should work:

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

And for third party targets:

./pants filter --filter-target-type=python_requirement_library ::

If you haven’t yet seen it, you may find https://www.pantsbuild.org/docs/project-introspection helpful. I still need to document

filter

- my bad!

Also you can use

./pants filter --target-type=python_requirement_library ::

, rather than

./pants filter --filter-target-type=python_requirement_library ::

. They’re different ways of typing the same thing

sometimes I get this error

Copy code

error	27-Aug-2020 07:34:27	13:34:27 [ERROR] Unrecognized command line flag '--target-type' on global scope. Suggestions:
error	27-Aug-2020 07:34:27	--filter-target-type, --target-types-details, --target-types-output-file, --target-types-sep

this was my command

Copy code

./pants --version && ./pants --changed-since=develop --changed-include-dependees=transitive filter --target-type=python_library | xargs ./pants setup-py ./pants --changed-since=develop --changed-include-dependees=transitive filter --target-type=python_library | xargs -i ./pants setup-py {} -- sdist && ./pants --changed-since=develop --changed-include-dependees=transitive filter --target-type=python_binary

Hmm, I can't reproduce this with any of those commands.

Is there a missing

&&

after the first

xargs ./pants setup-py

though?

To explain Eric's comment: The

--filter-target-type

flag means "The

target_type

option on the

filter

scope." This can be shortened to

--target-type

if it comes immediately after the

filter

goal on the command line. So that error means that pants encountered

--target-type

not immediately after

filter

This seems to be happening because of the missing `&&`:

Copy code

./pants setup-py ./pants --changed-since=develop --changed-include-dependees=transitive filter --target-type=python_library
11:31:03.16 [ERROR] Unrecognized command line flag '--target-type' on global scope. Suggestions:
--filter-target-type, --target-types-details, --target-types-output-file, --target-types-sep

Whereas

Copy code

/pants setup-py && ./pants --changed-since=develop --changed-include-dependees=transitive filter --target-type=python_library

should work

yes. you are right. my bad. the error code was misleading 🙂

3 weeks later…`filter` is now documented 🙂 https://www.pantsbuild.org/docs/project-introspection#filter---find-targets-that-match-a-predicate
