Code Style. Go
Use this page to configure formatting options for Go files. When you change these settings, the Preview pane shows how this will affect your code.
Tabs and Indents
Indentation widths are measured in spaces, not in tab characters. For example, an indent of 4 with a tab size of 4 uses one tab when Use tab character is selected.
Item | Description |
|---|---|
Use tab character | Use the Tab key for indentation. When the checkbox is cleared, IntelliJ IDEA uses spaces instead of tabs. This checkbox is selected by default. |

Tab size | In this field, specify the number of spaces included in a tab. Default value: |
Indent | In this field, specify the number of spaces to be inserted for each indent level. Default value: |
Continuation indent | Specify the indentation for lines that continue from the previous line, making it clear that they are part of the same statement or block of code. Continuation indents are used when a single statement is too long to fit on one line. Default value: |
Keep indents on empty lines | If this checkbox is selected, IntelliJ IDEA will keep indents on the empty lines as if they contained some code. If this checkbox is cleared, IntelliJ IDEA will delete the tab characters and spaces. This checkbox is cleared by default. |
Wrapping and Braces
Configure wrapping options and the usage of braces.

Function parameters | Select wrapping options for function parameters. In Go, function parameters are variables that are declared as part of a function signature and are used to pass data to the function when it is called. The values passed to the function as arguments are assigned to the function's parameters, allowing the function to operate on the data. You can select between the following options:
You can apply the previous options to opening and closing parentheses:
|
Function result parameters | Select wrapping options for function result parameters. In Go, result parameters appear after the parameter list in a function signature. They define the values that the function returns. You can select between the following options:
