Allow running a single bench from a file

[arjan]

Similar to mix test file:line, e.g.:

mix bench bench/template_bench.exs:37

Would you like to send a PR implementing this feature? :)

[arjan]

Sure, need to find some time for it though :)

Doesn't this already work? When I specify a file, it runs exactly that one for me with the current version:

mix bench bench/graph.exs

It only runs that single bench file and not others. That is handled in the paths param that is processed here: https://github.com/alco/benchfella/blob/master/lib/mix/tasks/bench.ex#L100

[arjan]

Yes but this is about running just one benchmark from a particular file. (you can have multiple benchmarks in a single file).

So adding a colon and the line number to the path argument.

I created a PR for this a while back, see #59.

[jdemaris]

Oh!!! Nice!! Yea, I saw the PR but I overlooked the details in the original comment. 👍

Any idea if this is still being maintained? I am starting to use it regularly.

[arjan]

I'm not sure... @alco ?

https://github.com/PragTob/benchee seems to be getting more love..

[jdemaris]

Yea unfortunately Benchee takes a different approach and everything is centered around comparing different ways of doing the same thing. It really did not fit my benchmarking needs.

I may just have to fork benchfella so we can maintain this. Benchfella is great for exactly what we needed
