Hi @holtgrewe I can't seem to replicate this with the latest snakefmt (v0.6.0)

$ singularity exec "docker://quay.io/biocontainers/snakefmt:0.6.0--pyhdfd78af_0" snakefmt --diff - << '@'
import contextlib

@contextlib.contextmanager
def some_helper():
    pass
@
=====> Diff for stdin <=====

  import contextlib
+

  @contextlib.contextmanager
  def some_helper():
      pass

[INFO] All done 🎉

Sorry, the following MWE is better.

# singularity exec "docker://quay.io/biocontainers/snakefmt:0.6.0--pyhdfd78af_0" snakefmt --diff - << '@'
rule run_varfish_annotator:
    run:
        print("")


@contextlib.contextmanager
def tmp_with_varfishrc(wildcards):
    pass

Thanks @holtgrewe I can recreate now.

We'll take a look at this after #136 is finished
