Mmm, I wonder how coverage implements these... go through the source matching and collect the set of lines that match, excluding them? That would seem easier than matching in the AST...

Yes, it's a regex on the raw line.

It cannot be done using AST because the patterns in exclude_lines may contain comments. Even more, the default exclude_lines excludes the lines with # pragma: no cover comments.

Semi-related, is there any way to exclude code blocks with pragma: no cover? It seems to only ignore the line that the no cover statement is on

if condition: # pragma: no cover
  print()  # will not be covered

No, SlipCover doesn't currently support this, sorry.

Being unable to exclude blocks is pretty much a blocker for me - I'd have to comment every line or live with a big reported regression in coverage, neither of which is desirable.

I hear you, folks. I will work on this ASAP.

Idk if you'd consider it part of this more general feature, but not counting stuff like if TYPE_CHECKING: blocks is also a blocker for me. I do have that as an explicitly exclude_lines for coverage, but (ditto with pragma: no cover, and assert_never) i wish it was just handled by default (and optionally turn-off-able)
