What would be the simplest way to get the dependency graph between all

python_distribution

targets? With the aim of highlighting and preventing circular dependencies between distributions?

if you can wait for 2.20, there is https://github.com/pantsbuild/pants/pull/20566 so you could export the adjacency list and filter your targets. This information is currently presented in the output of the

peek

goal as well, but requires a bit of JSON munging.

so you'd need to 1. get dependencies of all

python_distribution

targets, potentially transitively 2. get a list of

python_distribution

targets in the codebase 3. check if there are any targets from step (2) in the list of deps from step (1)

it sounds like a useful feature to be able to filter the dependencies based on a certain type (e.g. only show deps of type

python_distribution

but this would currently require two steps - you get all the deps and then you can filter them)

That 2.20 feature looks like exactly what I would want. Until then, I’ll try and whip something up! Thanks Alexey, hope you’re well 🙏 I was also wondering if there’s an alternative to Graph my Repo, since that is now shut down? Preferably one with a JSON output or similar. If you know of one?

Visualising a large graph is inherently challenging, but I have been somewhat successful using https://github.com/tweag/skyscope
