09/03/2015, 3:25 AMSo. I am trying to make a pants repo with go code in it. My pants.ini has 'pants.contrib.go' listed under backend_packages, but pants fails complaining that 'Exception message: Failed to load the pants.contrib.go.register backend: No module named contrib.go.register'. Is there a step I'm missing to make contrib moules available (presumably on pythonpath)? - c

09/03/2015, 3:26 AM(Pants 0.0.45) - b
bored-art-40741
09/03/2015, 3:26 AMYou also need the python package for the backend installed - b
bored-art-40741
09/03/2015, 3:27 AMAre you running out of a virtualenv? - c
cuddly-accountant-94274
09/03/2015, 3:27 AMIt's not expected to be in the self-bootstrapped pants? - b
bored-art-40741
09/03/2015, 3:27 AMNo - c
cuddly-accountant-94274
09/03/2015, 3:27 AMYeah, I followed the virtualenv instructions. - c
cuddly-accountant-94274
09/03/2015, 3:27 AMSelf-bootstrap and then pinned version to 0.0.45. - b
bored-art-40741
09/03/2015, 3:27 AMcontrib modules are explicitly opt-in - c
cuddly-accountant-94274
09/03/2015, 3:27 AMAh, okay. - c
cuddly-accountant-94274
09/03/2015, 3:27 AMThat would explain it then. - b
bored-art-40741
09/03/2015, 3:27 AMSo in your virtualenv, install the 0.0.45 package for the go contrib module - c
cuddly-accountant-94274
09/03/2015, 3:28 AMAs in, I should be manually touching the virtualenv set up by pants? - b
bored-art-40741
09/03/2015, 3:28 AMYeah, kinda gross, I was just thinking about that - b
bored-art-40741
09/03/2015, 3:29 AMTo be honest, I'm less familiar with the self-bootstrapping approach since we have a bunch of customization of the environment internally - c
cuddly-accountant-94274
09/03/2015, 3:29 AMOk. Thanks! - b
bored-art-40741
09/03/2015, 3:29 AMSo I'm not sure if we have a pants.ini config that does this for you, but I doubt it? - b
bored-art-40741
09/03/2015, 3:29 AMIn which case I'd just pip install within your virtualenv the extra packages that you need - c
cuddly-accountant-94274
09/03/2015, 3:30 AMFTR, https://pantsbuild.github.io/install.html actually does have instructions for this as long as the plugin is on pypi. - b
bored-art-40741
09/03/2015, 3:30 AM(that's what we do internally, with a bit of chrome to help operate from patched sdists) - c
cuddly-accountant-94274
09/03/2015, 3:30 AMAnd that did indeed do the trick - b
bored-art-40741
09/03/2015, 3:30 AMAh okay, I was wrong then - b
bored-art-40741
09/03/2015, 3:31 AMI know there's a list of plugins you want to register, and it does make sense there's an equivalent list of the ones you want to install - b
bored-art-40741
09/03/2015, 3:33 AMOh. I think I wrote this originally. How time flies. - c
cuddly-accountant-94274
09/03/2015, 3:33 AM😄 - b
bored-art-40741
09/03/2015, 3:37 AMnaturally John is the canonical author, but I do remember writing the original plugins backend back in the day - e
enough-analyst-54434
09/03/2015, 5:58 AMYeah - David Taylor added support for setuptools entrypoints -> register.py and then I did some work most recently to 1. publish our plugins with those entrypoints defined, 2. resolve the plugins using the rules you have setup for python repos and indexes, 3. leverage all this in pantsbuild.github.io/setup - r

09/03/2015, 6:08 AMhave you ever thought about pex’ing plugins and using PEX_PATH?
