Description

Hi I'm interested in using batchtools but after looking at the documentation I'm not sure if batchtools has support for dependencies between jobs, which is a key feature that I would need. It is documented for SLURM on https://slurm.schedmd.com/job_array.html

e.g

# Wait for entire job array to complete successfully
sbatch --depend=afterok:123 my.job

If batchtools does support dependencies, where are the docs?

If not, how hard would it be to implement?

Research direction

Start by reading the batchtools documentation and the SLURM job-array dependency documentation linked in the issue. Determine whether batchtools already exposes job dependencies and, if not, identify the scope needed to support them across its batch systems. Done should mean either documenting existing support or defining and implementing a tested dependency workflow.
