Execute gofmt on file save in IntelliJ

Question

I use IntelliJ with the Golang plugin. Is it possible to configure the IDE to execute gofmt on file save?

Solution 1

Of course you can.

1. install File Watchers plugin
2. open "Preferences->Tools->File Watchers" & Add a new watcher
3. set File Type: Go, Program: the abosolute path of gofmt, Arguments: -w $FilePath$
4. click OK

Solution 2

Gogland EAP 16 deprecated the On Save actions and replaced them with the File Watchers plugin.

If you have previously configured On Save actions, the IDE will prompt you to install the plugin and configure everything automatically. If you want to set it up from scratch yourself, check if you have File Watchers plugin and if not install it.

Enable gofmt:

1. Go to Settings | Tools | File Watchers.
2. Click the + button and select go fmt.
3. The default values are good.
4. In Advance Options select:
   • Auto-save edited files to trigger the watcher
   • Trigger the watcher on external changes
5. Click ok!

You can do the same for goimports and gometalinter.

Solution 3

If you are using Gogland, you have an option On Save under Preferences

Solution 4

Updated:

For new versions of the Goland:

1. open File->Settings->Tools->File Watchers
2. click on + button and choose go fmt
3. press Ok

Done :)

Solution 5

September 2021 Update.

If you are using GoLand with the 2021.2 version and higher (July 2021), there are a few options to enable gofmt on save besides File Watchers.

• Enable Run gofmt on code reformat under Preferences/Settings | Editor | Code Style | Go | Other.
• Enable Reformat code under Preferences/Settings | Tools | Actions on Save.
• Press Command + S on macOS or Ctrl + S on Windows/Linux to save your changes.
