Alternative
However, you can somewhat achieve the desired behavior by using Custom Postfix Templates plugin, which allows to define your own custom postfix completion templates.
Statement like this:
Will be converted to:
To achieve this:
- 1) Install Custom Postfix Templates plugin via Settings → Plugins → Browse Repositories.
- 2) Press Shift+Alt+P (or go to menu Tools → Custom Postfix Templates → Edit Templates of Current Language) to open the custom postfix templates for the programming language in your current editor.
3) Add the following template:
.var : Extracts variable as inferred 'var' type NON_VOID → var $VAR:suggestVariableName()$ = $expr$;
Restart IntelliJ and you're good to go.
Note. Existing postfix completion named 'var' exists in IntelliJ by default, you might want to disable the existing one (via Settings → Editor → General → Postfix Completion) or find another name for a new one.
