Inlay hints

Code vision

Code vision hints display in the editor the number of inheritors and usages for a symbol, show who authored it, and mark symbols that are new or contain uncommitted changes.

When you hover over a hint, it turns into a link. By clicking the link you can navigate to usages or implementations of the class or interface as well as open Version Control annotations.

• Inheritors show the number of descendants of a class (inheritors), interface (implementations), or trait (used by`s). Click the hint to jump to the descendants. If there are several descendants, select the relevant one from the list. Learn more from Go to implementation.

  

• Usages show how many times a class or a method is used in your project. Click the hint to jump to the usage or to select the relevant one from the list. Learn more from Search for usages in a project.

  

• Code author shows the person who wrote/edited most code lines in a given code element. The hint also indicates if the element is new, modified in the current revision, or has several contributors who considerably committed to it. Click the hint to open the Git annotations in the gutter. Learn more from Locate code author.

  

In the right-hand pane of the dialog, configure the default position of inlay hints—whether they should be displayed above symbols or to the right of them—and specify the maximum number of inlay hints to be shown in each position.

You can also configure custom positioning for hints of a specific type.

Parameter names

Show the names of parameters in function and method calls. These hints provide assistance with passing correct arguments to functions and methods.

The PHP-specific parameter name options are:

• Show name for all arguments: if selected, parameter name hints are displayed for all arguments. Otherwise, parameter hints are displayed only for literals or null values but not for named objects.

  

• Always show pass by reference: if selected, the & parameter hints are shown for arguments that are passed by reference. The names of the arguments that match the parameters' names are omitted if the Show name for all arguments checkbox is cleared.

  

For a number of methods and functions, parameter names are not shown by default: such methods and functions are on the default Exclude List. To re-enable the excluded parameter name hints or add more excluded methods or functions, click Exclude list and edit the list.
