benchee_json

Formats a benchee benchmarking suite to a JSON representation and can also write it to disk. Actively used in benchee_html to generate JSON, and embed it into the JavaScript to give the JS access to the benchmarking results for graphing purposes.

Installation

Add benchee_json to your list of dependencies in mix.exs:

def deps do
  [{:benchee_json, "~> 0.4", only: :dev}]
end

Usage

Like a normal benchee formatter:

list = Enum.to_list(1..10_000)
map_fun = fn(i) -> [i, i * i] end

Benchee.run(%{
  "flat_map"    => fn -> Enum.flat_map(list, map_fun) end,
  "map.flatten" => fn -> list |> Enum.map(map_fun) |> List.flatten end
},
  formatters: [
    {Benchee.Formatters.JSON, file: "my.json"},
    Benchee.Formatters.Console
  ]
)

You can get started with a look at the open issues.

A couple of (hopefully) helpful points:

• Feel free to ask for help and guidance on an issue/PR ("How can I implement this?", "How could I test this?", ...)
• Feel free to open early/not yet complete pull requests to get some early feedback
• When in doubt if something is a good idea open an issue first to discuss it
• In case I don't respond feel free to bump the issue/PR or ping me on other places

Development

• mix deps.get to install dependencies
• mix test to run tests
• mix credo or mix credo --strict to find code style problems (not too strict with the 80 width limit for sample output in the docs)
