This rule checks, if variables are named in one of the cases that you have defined in the config.

AllowVariableCases.allowedCases can be defined as an array containing:

• camelCase
• snake_case
• PascalCase
• UPPERCASE (also allows underscores like UPPER_CASE)

Default is [camelCase].

You can define multiple cases, that are allowed. For example [camelCase, PascalCase].

lowercase is also recognized, but is allowed with camelCase or snake_case.

Configure the rule by setting AllowVariableCases.allowedCases = [...] in your .scalafix.conf. For example: AllowVariableCases.allowedCases = ["snake_case"]

You can execute scalafix dependency:[email protected]:scalafix-rules:1.0.0 in the sbt shell.

To install the rule for your build update the scalafixDependencies in your build.sbt for example like this

ThisBuild / scalafixDependencies +=
  "de.spaceteams" %% "scalafix-rules" % "1.0.0"

and execute scalafix AllowVariableCases in the sbt shell.

You can use this rule directly from GitHub by executing scalafix github:spaceteams/scalafix-rules/AllowVariableCases in the sbt shell.
