icecream and rlang 1.0.0

[lionel-]

Hello, I see in revdep checks:

  ══ Failed tests ════════════════════════════════════════════════════════════════
  ── Failure (test-icecream.R:76:3): source file is correctly identified ─────────
  `f()` did not throw the expected message.

I took a look and it's because you're subsetting the object returned by trace_back(). The structure of this object was undocumented and has now changed (as well as become public). You can fix your package with this patch:

modified   R/ic.R
@@ -25,10 +25,10 @@ ic <- function(x) {
   # In the event that icecream is totally disabled we will just return the input.
   if (getOption("icecream.enabled")) {
     trace <- trace_back()
-    num_calls <- length(trace$calls)
+    num_calls <- length(trace$call)
 
-    parent_ref <-  if (num_calls > 1) trace$calls[[num_calls - 1]][[1]] else NULL
-    ref <- attr(trace$calls[[num_calls]], "srcref")
+    parent_ref <-  if (num_calls > 1) trace$call[[num_calls - 1]][[1]] else NULL
+    ref <- attr(trace$call[[num_calls]], "srcref")
     loc <- src_loc(ref)
 
     # Case when location of file is unavailable

We plan to release rlang 1.0.0 in 2 to 4 weeks.

Thanks @lionel- appreciate you taking the time to send a patch! I've got some housekeeping to do anyway so this is a good incentive. Cheers 👍
