Extract/Introduce variable
If you come across an expression that is hard to understand or it is duplicated in several places throughout your code, the Extract Variable refactoring Ctrl+Alt+V can help you deal with those problems placing the result of such expression or its part into a separate variable that is less complex and easier to understand. Plus, it reduces the code duplication.
You can use the Introduce Variable refactoring to extract variadic arguments into a new slice variable.
Extract a variable
In the editor, select an expression or its part that you want to extract. You can also position the caret within the expression, in this case GoLand offers you a list of potential code selections.
Press Ctrl+Alt+V or from the main menu, select .
- Select a name suggested in the popup or type your own and press Enter.
If GoLand finds more than one occurrence, it lets you specify a scope and extract just a part of the found occurrences and not just all of them.
