If you are using integer keys, use:

20: test
Instead of:
"20": test

If you are using key after bullets definition and need more dimension arrays, use:

	- factory: Foo\Bar
	  	key: [foo: 123, bar: 456]
Instead of:
	- factory: Foo\Bar
			foo: 123
			bar: 456

Known limitations

Services and parameters refactoring

  • Here problem with refactoring services and parameters that have more than one definition (only usages will be refactored)
  • For services and parameters with only one definition everything works fine

Move class

  • For now is not implemented Move class functionality. If you use it in PHP, then it will not affect Neon files.

Do not use mixed indents

  • Do not use mixed indents. Use only tabs or spaces
  • If you use spaces, use same count of spaces on all levels
  • Exception is only key after bullet where are used two spaces


Since 1.0.0, IntelliJ NEON Nette Support plugin is compatible with all major JetBrains IDEs with version 2021.1.1 and higher.
