• [gentoo-dev] [PATCH 02/11] ruby-ng.eclass: optimize: use pattern substi

    From Sam James@21:1/5 to All on Thu Jun 15 18:00:01 2023
    We can save a little bit (consistently a few ms) by using patsubs in some obvious cases.

    Not really any difference globally, but for sinatra:
    ```
    $ pk pkg source $(pkg) --repo ~/g/ --bench 5s # before dev-ruby/sinatra-3.0.5::/home/sam/g/: mean: 76.25ms, min: 59.23ms, max: 83.674ms, σ = 4.247ms, N = 66
    dev-ruby/sinatra-3.0.5-r1::/home/sam/g/: mean: 77.465ms, min: 61.782ms, max: 85.127ms, σ = 3.592ms, N = 65
    dev-ruby/sinatra-3.0.6::/home/sam/g/: mean: 80.192ms, min: 60.922ms, max: 84.951ms, σ = 3.899ms, N = 63
    dev-ruby/sinatra-2.2.3::/home/sam/g/: mean: 80.389ms, min: 56.818ms, max: 86.915ms, σ = 4.508ms, N = 63

    $ pk pkg source $(pkg) --repo ~/g/ --bench 5s # after dev-ruby/sinatra-2.2.3::/home/sam/g/: mean: 66.68ms, min: 56.938ms, max: 74.248ms, σ = 4.832ms, N = 75

    dev-ruby/sinatra-3.0.5-r1::/home/sam/g/: mean: 73.265ms, min: 60.738ms, max: 81.06ms, σ = 3.227ms, N = 69
    ```
