Coding Assistance in Groovy

IntelliJ IDEA supports the following coding assistance for Groovy:

• Code completion for keywords, labels, variables, parameters and functions.

• Chained expression completion.

• Error and syntax highlighting.

• Code formatting and folding.
  For example, all closures that have their parameters described in the separate line are formatted the following way:
  

  def cl = { param1, param2 -> body() }

• Numerous code inspections and quick-fixes.

• Ability to check what generics to specify for a method call or for a type variable using Parameter info (Ctrl+P).

• Code generation

  • Support of Groovy 3.0 syntax except for Java-style Lambda syntax and nested code blocks.

  • Inserting, expanding, and generating code blocks using live templates.

  • Creating various applications elements via intention actions.

  • Possibility to create line and block comments (Ctrl+//Ctrl+Shift+/).

• Ability to add annotations. For example, @Builder annotation. IntelliJ IDEA supports all Strategies from the standard library as well as code completion and navigation.

  

• Expression Type action for Groovy expressions. Use Ctrl+Shift+P to see the expression type without clicking the mouse.
