Language	Linter	Styles
Java	Checkstyle	Sun Java Style or Google Java Style Guide
Groovy	CodeNarc	Groovy Style Guide
Kotlin	Ktlint	Ktlint Official Style
C/C++	Cppcheck	C++ Core Guidelines or Google C++ Style Guide

• Point to local config file or put in /config/checkstyle/codenarc.xml.

  plugins {
      checkstyle
  }
  
  checkstyle {
      toolVersion "$checkstyleVersion"
      configFile "path/to/rulebook_checkstyle.xml"
  }
  
  dependencies {
      checkstyle "com.hanggrian.rulebook:rulebook-checkstyle:$libraryVersion"
  }

CodeNarc

• Apply CodeNarc Gradle Plugin.

• Using configuration codenarc, add this project as dependency.

• Point to local config file or put in /config/codenarc/codenarc.xml.

  plugins {
      codenarc
  }
  
  codenarc {
      toolVersion "$codenarcVersion"
      configFile "path/to/rulebook_codenarc.xml"
  }
  
  dependencies {
      codenarc "com.hanggrian.rulebook:rulebook-codenarc:$libraryVersion"
  }

Ktlint

• Apply Ktlint Integration to Gradle project.

• Using configuration ktlint, add this project as dependency.

  configurations {
      ktlint
  }
  
  dependencies {
      ktlint "com.hanggrian.rulebook:rulebook-ktlint:$libraryVersion"
  }
  
  // the rest of ktlint tasks' configuration

Cppcheck

Create addon.json file.

Pylint

Create .pylintrc file in the root directory.

ESLint

Create .eslint.config.js file in the root directory.

IDE settings

Presuming the IDE is IntelliJ IDEA or PyCharm, consider applying the linter style to it.

1. Ktlint Style

   Explained in Ktlint IntelliJ IDEA Configuration, using standard Kotlin coding conventions is enough:

• In File > Settings > Editor > Code Style > Kotlin, set from Kotlin style guide.
  • Append kotlin.code.style=official to root gradle.properties.

1. Google Java Style

   Explained in Google Java Format:

   • In File > Settings > Editor > Code Style > Java, import IntelliJ Java Google Style file.
