Hi pants! What’s the recommended way to install a 1st-party CLI tool from source in “editable” mode using

pants

? This would be helpful to use while developing the tool so changes to source are reflected when using the CLI tool without having to uninstall / reinstall. From reading the

pants

docs, it seems like using a

python_distribution

with

entry_points

might be my best bet for installing said CLI tool, but I’m not finding if there is a way to install this distribution in “editable” mode. Let me know if I’m on the wrong track, too…

https://twitter.com/pantsbuild/status/1442593447072911361 Congrats and thank you to Pants Contributor Alexey Tereshenkov for landing yapf support in the brand new Pants 2.7. A quick tutorial, and background story on the experience of contributing to the project: https://t.co/O4rH0IBFra https://t.co/aF5iedUIpv Twitter

Hey Pants Team, we're testing upgrading to

2.7.0

and now

./pants tailor

is adding

pex_binary

targets to our python files that have

if __name__ == "main"

. Is this intentional? Created an example of this here: https://github.com/njgrisafi/pants-example/tree/pex-binary-example-2.7.0

What decides what python version the

.pex

file gets built to expect?

https://twitter.com/pantsbuild/status/1442946892615196674 Have you checked out the new Pants 2.7 release? Lots of goodies for you: * yapf * Docker * lockfiles * ASDF *

./pants peek

(handy for incremental adoption!) * better Apple Silicon support * perf improvements * PEP 561 and more https://t.co/zqd0QgMCvi https://t.co/aF5iedD70V Twitter

Seeking: more contributors to blog.pantsbuild.org. Got something to say about Pants? A few ideas: how your team uses Pants, what problems you're solving, a favorite feature, your experiences of the community and/or of contributing back to it, etc. Ping me with your ideas. We'd love to share more posts from community members. Thank you to community members @fresh-cat-90827 and@curved-television-6568 for this week's posts on yapf and Docker, respectively!

P.S. We also love when you blog about Pants at your own site and your company's. Many people tell us they found Pants through other folks' blog posts about it. So when you share your Pants knowledge, you bring new people into the community. Thank you!

The new docker image stuff is sweet. Is there currently a way to authenticate the docker client for private repos? Looking to pull from AWS ECR.

I'm just about to merge in basic registry support. Will follow up with support for more configuration options such as certificates etc.

Awesome!

Hello everyone - myself and the company that I work for would like to use Pants big times. Our code is Python based and it has grown large enough to become hard to package and deploy since it takes significant time. We would like to have a build system that will detect the relevant changes and do the relevant work based on the changes. So we chose to go with Pants and it seems promising. My question is this: Is there a service that can be provided to guide us and help us during this transition to Pants?

Hi 🙂 I'm just taking a first look at Pants and seem to have run into problems early on, I've had a look but can't find any info suggesting where to look 😞 I've made a very simple repo with a couple of projects, using poetry with a pyproject.toml in the root If I add in a dependency (poetry add x) that's working fine, adding into the pyproject.toml and poetry.lock as expected For some reason if I add in pandas / numpy as an import in one of the src files, it fails. Other dependencies (to pick some random ones, pytz and requests) are both fine. It's coming back with:

Exception message: 1 Exception encountered:

ProcessExecutionFailure: Process 'Building requirements.pex with 3 requirements: pandas<2.0.0,>=1.3.3, pytz<2022.0.0,>=2021.1, requests<3.0.0,>=2.26.0' failed with exit code 1.

stdout:

stderr:

ERROR: Could not find a version that satisfies the requirement pandas<2.0.0,>=1.3.3

ERROR: No matching distribution found for pandas<2.0.0,>=1.3.3

pandas 1.3.3 definitely exists, I'm not sure why specifically pandas and numpy are causing problems but doing the same thing for other dependencies is fine 🤔 Any suggestions on where to look for this? Thanks!

hi there

can one have multiple constraints.txt files in a Pants monorepo?

@curved-television-6568 not sure if you'd consider it a bug. But I have multiple customers, and each of which have a creatively named

base

docker image (amongst other conflicting image names) the solution for this was change all their build/deploy scripts to name their docker images

<companyname>/base

or similar. Buuuut, I can't do that with the 2.7 pants

docker_image

target, because

/

is a disallowed target name. Is there a way to specify the image name of a

docker_image

target to be something other than the

name

property?

Hi! I’m trying to use pants in an airgapped CI. I’m following the instructions in https://www.pantsbuild.org/docs/proxies I have the

pex

dependency stored under a

pants_files

directory at the root of my repo. What should my

pants.toml

look like for

pants

to use the local

pex

file instead of downloading it form the internet? This does not work

[download-pex-bin]
url_template="<file://pants_files/pex>"

It fails with

Exception: Error (No such file or directory (os error 2)) opening file at /pex for download to pex

There is a section in the documentation for

python-native-code

Is this only for resolving third party deps or is there a way to build c bindings locally? Was also thinking about trying

python_ditribution

Hey all, I've been using Pants off and on for a few weeks now at work. I was previously using version 2.6.1rc3 without issue. I just tried updating to pants version 2.7.0 so I could try out some of the new features, however I got the following error when trying to use ./pants --version to bootstrap my pants 2.7.0 install:

./pants --version

I tried switching my pants.toml to point back to 2.6.1rc3 and that is now throwing the same error. I have tried deleting my ~/.cache/pants directory without any success. Can someone help point me in the right direction?

Hi folks, I'm wondering if there is a tutorial on how to write a codegen rule and target? I got a little lost trying to read how protobuf codegen works 😅 I'm trying to add a target + rules that generate files using templated params from the target.

anyone familiar with what this message means in PANTS "Canceled: Remote cache lookup for:" - given I am attempting to use remote caching in my pants.toml?

hey team. I am wondering how Pants deal with

pytest

skipping the tests when they are selected with markers?
