- Fixes tprof :) #439
- also fixes one of the samples not being an .exs 😁
- also updates it and includes tprof
- might consider only adding it on elixir 1.17+ but may be too much
- still needs to be added to docs

Of course I wrote a test that all built-in profilers work 😂 |

I wonder if there is a way to pass opts to the profilers, like call_memory to tprof to get heap allocs?

Benchee already supports profile_after: {profiler, opts}
🤦

Absolutely! See https://github.com/bencheeorg/benchee?tab=readme-ov-file#configuration for profile_after
a profiler - either as a tuple of {profiler, opts} (e.g., {:fprof, [sort: :own]}) or just the profiler (e.g., :fprof), which is equivalent to {profiler, []}. The accepted built-in profilers are :cprof, :eprof and :fprof.
Should make that clearer/include it in the profiler section of the README though!

ah didn't see your response, sometimes github auto fetches sometimes it doesn't - but yeah :)

And of course I run 1.17 against erlang versions that don't have tprof yet and so I need to fix that behavior as well or fix the tests... 😅 Erlang versions are much worse though, sadly. |
