is there a way to make
./pants dependencies --type=3rdparty
output the value of
[python-repos].indexes.add
as well?

Hello! Not currently. Do you mean that you want for some deps to use a particular index, and others to use a different index? To get the value of
[python-repos].indexes
, you can use either
./pants help-advanced python-repos
, which will show you the current value. Or use
./pants help-all
, which will output JSON and you can use something like JQ to parse.

i'm trying to script up creating a virtualenv from the deps so my IDE can understand what's going on 🙂
i think for now i can just hard code the extra index into the script; the goal would to be to migrate those deps into the monorepo anyways, so i don't need to maintain this forever

Very helpful indeed. See https://www.pantsbuild.org/docs/python-third-party-dependencies#tip-set-up-a-virtual-environment-optional for a starter script

this is the beginning of it with `help-all`:
Copy code
./pants help-all | jq '.scope_to_help_info["python-repos"].advanced | map(select(.config_key=="indexes")) | .[0].value_history'
… although the structure doesn’t seem to render the final value directly, so you’d still need some logic.

…the whole thing:
Copy code
./pants help-all | jq '.scope_to_help_info["python-repos"].advanced | map(select(.config_key=="indexes")) | .[0].value_history.ranked_values[-1].value'

(maybe… cc @happy-kitchen-89482)
but more generally, we should probably expose venv export for IDE and jupyter purposes.

nice jq, i would have had no idea how to write that 😄

on this note, is there a good way to export "editable installs" to this venv? i'm trying a BUILD file in the source root and a
python_distribution()
target but there might be a better way

You want to create a
.whl
for your code, and then have pip install it via an editable install? What’s the motivation? Generally, for an IDE with creating the venv, I’d think you only want your 3rdparty reqs in it, and then have the IDE treat your first-party code like it normally would, rather than loading it via an editable install

hmm maybe i don't know how to confgure my IDE right then

Which IDE are you using?

i'm using vscode, which seems to defer as much as possible to the code environment it's connected to
reading now on the options though

Okay cool, and it isn’t understanding your first-party imports, it sounds like? What are your source roots configured to for Pants? For PyCharm, I had to teach it that
src/python
is a source root so that it knows the import
pants.util.strutil
is really from
src/python/pants/util/strutil.py
i guess i've always leaned on virtualenvs + editable installs before to make this work, so i didn't think to look at the IDE settings
