Dynamic path for publish section

[Puumanamana]

Hello,

I'm trying out the new publish feature introduced in version 24.04.0, but wasn't able to figure out the right implementation in my case. In my current pipeline, a single workflow execution can process multiple datasets at the same time, so I need to publish each process output to the correct output directory (matching its dataset). I'm currently doing that using a closure that takes the dataset field of the map associated to each channel element. Here's a snapshot of my publishDir directive:

publishDir = [
  path: { meta, output -> "results/$meta.dataset/${task.process.split(':')[-1]}" }
]

With the new syntax, files can be published with the >> operator within a process or workflow in the publish section. However, I couldn't identify in the documentation how to add a dynamic directive with a closure applied to the objects being published (if it's still possible)

It is not currently supported, but we are going to add it in the final version as many users have requested it.
