(OeditusCredo v0.11.1)
View Source
Basics
This check is disabled by default.
Learn how to enable it via .credo.exs.
This check has a base priority of normal and works with any version of Elixir.
Explanation
Chaining multiple Map.put calls for literal keys is inefficient and verbose. Use Map.merge(map, %{key: val}).
Bad:
map |> Map.put(:a, 1) |> Map.put(:b, 2)Good:
Map.merge(map, %{a: 1, b: 2})Check-Specific Parameters
Use the following parameters to configure this check:
:exclude_test_files
Set to true to skip test files (default: false)
This parameter defaults to nil.
General Parameters
Like with all checks, general params can be applied.
Parameters can be configured via the .credo.exs config file.
