Hello. We are trying to write a shell scriptsthat wraps an execution of a few python binaries. e.g., something like -

script.sh

./proj/main.py | ./proj/main2.py | ./proj/main3.py

How can i achieve this with pants? (We looked at

shell_source

, but it does not appear to be a runnable target. Also shunit2_test is almost what we need, except this is not a test in our case)

If shell source isn't runnable, it should be 😬

You may find this useful https://www.pantsbuild.org/docs/plugins-codegen

@bitter-ability-32190 i tend to agree 🤷‍♂️ (this is pants 2.16)

Feel free to open annussue

I mean you can include an external tool and use it with a goal_rule or create a dedicated target

Thanks @acoustic-house-77496, i'll look into it:) I can't not wonder though - i'm probably missing something very basic. Isn't running shell scripts a common use case?

If you want just to invoke it on demand you can create a ‘@goal_rule’ and use the external tool there

I'm hoping to find a bit simpler solution, as this seems to be a bit of an overkill for my case. But let's see 🙂

Until recently-ish sources were thought of to be something that goes into a runnable thing (think Java) Scripts, of course occupy both, but unless PRs are made, things don't change 🙂

Thank you!

run_shell_command

worked. The key was to use

CHROOT

which i previously missed.

You may also be able to use

runnable_dependencies

https://www.pantsbuild.org/docs/reference-run_shell_command#coderunnable_dependenciescode as part of

run_shell_command

seems like a

pex_binary

cannot be specified as a

runnable_dependency

.. Output:

❯ pants run stimulus/flask_server:my_script
