Feature Request: Add an option to log task timings

[chrisguest75]

I'm trying to find a nice pattern to log out task timings. I'm using just for various processes and I have cases where I'd like to understand the impact of cmd switch on performance.

I've just come up with this way of logging out the timestamps, but it is a bit manual and messy. The alternative is use an external tool an annotate the justfile.

It would be good for just to summarise at least the top level task execution stats or a graph in a json file if you wanted to support a full breakdown.

just --timestamp mytask

_start_task name="":
  echo "Start {{ name}}"

_end_task name="":
  echo "End {{ name }}"

mytask: (_start_task 'mytask') && (_end_task 'mytask')
  #!/usr/bin/env bash
  set -eufo pipefail
  tool --slow-switch

Thanks for such a cool project. It's really changing the way I document my tiny projects.

Maybe there could be a config option which would log a JSON summary of a just invocation to a file.

One quick and dirty thing you could do in meantime is use strace to log syscalls, look for process invocations, and figure out the timings from that.

Glad you like it! ☺️

Another thing maybe to OTEL enable it. I mean this would open up a whole world of possibilities for monitoring build pipelines and any subprocesses that are also OTEL enabled.

Scope Creeping already :D

Currently I'm using time like this -> time just mytask

Thanks for the quick reply.
