Is there a mechanism for inferring targets from sources? Or is it just dependency inference on existing targets?

there is a

dependees

goal.

to clarify, I have a plugin that I want to auto-generate targets given the presence of source files with a specific extension

ah.. I didn't notice this was asked in the plugins channel 🤦‍♂️

🙂

Yeah, there is not "target gen", only "codegen" which operates on

sources

For now,

./pants tailor

is the solution, with an acknowledgment that we want to move away from needing targets so much in the future. Check out the Shell implementation with

shell/tailor.py
