For a single file, you can use the built-in import management and code formatter. Imports are managed on-the-fly. To customize import management, open settings by pressing Control+Alt+S and navigate to.
To reformat code, press Control+Alt+L. Comparing to gofmt, IntelliJ IDEA’s formatter works with syntactically incorrect code and can be invoked on an arbitrary block. There are other features such as automatically inserting semicolons, wrapping parameters and arguments, and others.
Also, you can use On code reformat option ( , click Other tab). This option lets you invoke both formatters by pressing Control+Alt+L whenever you want.
Alternatively, use the Reformat code option in Actions on Save. This action is enabled by default for IntelliJ IDEA. When triggered by pressing Control+S, the IDE runs the built-in IntelliJ IDEA formatter and gofmt.
