Great news for fans of Intellij IDEA: “Surroud with…” action is now available for Kotlin!
What is the “Surround with…” action?
This action allows you to surround a block of code with if, try or other statements (see the full list bellow). Simply select a block of code, press Ctrl + Alt + T and choose the template (Cmd + Alt + T for Mac):
The IDE will add the neccessary code and put the caret at the position that allows you to finish your refactoring:
If the surrounded block contains variable declarations that are used after the block, they will be moved out of the block:
Function Literal Template
You can surround a block of code like this:
Use this template if you want to “hide” some variables in the scope of the block, to create a property with function type or a local function and if you want to call any function with function literal as an argument.
When template
You don’t need to write when expression by hand any more: you can simply select a subject expression, choose “surround with when(expr) {}” and the result will be:
Full list of “Surround with…” templates
When a block of code is selected:
- if
- if / else
- { } – function literal

- try / catch / finally
When an expression is selected:
- !(expr) – add negation for Boolean
- (expr) – surround with parentheses
- “${expr}” – surround with quotes
- when(expr) {}

We release “Surround with…” as a part of Kotlin M5.1 that will be out very soon.
