formatting - Intellij reformat on file save

Question

I remember seeing in either IntelliJ or Eclipse the setting to reformat (cleanup) files whenever they are saved. How do I find it (didn't find it in the settings)

Answer 1

This solution worked better for me:

1. Make a macro (I used Organize Imports, Format Code, Save All)
2. Assign it a keystroke (I overrode Ctrl+S)

Note: You will have to check the box "Do not show this message again" the first time for the organized imports, but it works as expected after that.

Step-by-step for IntelliJ 10.0:

1. Code -> "Optimize Imports...", if a dialogue box appears, check the box that says "Do not show this message again.", then click "Run".
2. Tools -> "Start Macro Recording"
3. Code -> "Optimize Imports..."
4. Code -> "Reformat Code..."
5. File -> "Save all"
6. Tools -> "Stop Macro Recording"
7. Name the macro (something like "formatted save")
8. In File -> Settings -> Keymap, select your macro located at "Main Menu -> Tools -> "formatted save"
9. Click "Add Keyboard Shortcut", then perform the keystroke you want. If you choose Ctrl+S like me, it will ask you what to do with the previous Ctrl+S shortcut. Remove it. You can always reassign it later if you want.
10. Enjoy!

For IntelliJ 11, replace

step 2. with: Edit -> Macros -> "Start Macro Recording"
step 6. with: Edit -> Macros -> "Stop Macro Recording"

Everything else remains the same.

8. The Preferences contain the Keymap settings. Use the input field to filter the content, as shown in the screenshot.
