I know this question is quite old but there is actually a Save Actions plugin for IntelliJ that can be configured to format the code automatically

None of the solutions in Intellij is as elegant  or useful  as in Eclipse  What we need is feature request to the intellij so that we can add a hook  what actions to perform  when the IDE autosaves    In Eclipse we can add  post-save  actions  such as organize imports and format the class  Yes you have to do a  save  or ctrl-s but the hook is very convenient

Well that s not possible  but in intellij 13  how about adding a mouse gesture  something like single left mouse click to reformat the code  Or if you don t use the mouse much then add a very simple keyboard hotkey that you use all the time  possibly the  enter   not sure if intellij would be happy with that to be honest

You can do this with Save Actions plugin Refer This article on how to configure the plugin      Save Actions plugin Supports configurable  Eclipse like  save actions  including  optimize imports    reformat code    rearrange code    compile file  and some quick fixes for Java like  add   remove  this  qualifier   etc  The plugin executes the configured actions when the file is synchronised  or saved  on disk     Install the plugin Go to Settings   Other settings   Save actions Tick Activate save actions on save Tick Reformat file Apply   OK     I prefer the hot-keys though  For Mac   To format the code   Ctrl Alt Option  L  And additionally I do   Ctrl Alt Option  O   This will remove unused imports and format the import list as well

I have found two ways to do this    Go to Settings gt  Keymap In the right portion go to Editor Actions gt  complete current statement Click on it and select add keyboard shortcut  Press   and select ok  Use macro  Go to   Edit gt  Macros gt  Start Macro Recording   Now press semicolon and keyboard shortcut to reformat code  you can find the keyboard shortcut from other answers or from settings   keymap    After doing reformat go to  Edit gt  Macros gt  Stop Macro Recording  Save the macro with a name  auto format or something else   Then go to   Settings gt  Keymap gt  Macros gt  auto format  the macro name    Click there and select add keyboard shortcut  then press semicolon and click ok  Now whenever you will press semicolon it will write semicolon and do auto format

This can also be achieved by Ctrl WindowsBtn Alt L  This will be important to some people because in some Virtual Machines  Ctrl Alt L can log you out

File-  Settings -  Keymap-  Complete Current Statement  I added   key in there  When typing     at the end of the line  it is auto-formatting   UPDATE  I realized that this will cause some problems in some situations  Use Ctrl Shift Enter instead  This key can be used in any position of cursor in a line  It will add   at the end of the line  Also this shortcut have some other useful features   like   public void someMethod     after shortcut   public void someMethod            The cursor is here     so formatting on inserting   is not necessary

Eclipse has an option to format automatically when saving the file   There is no option for this in IntelliJ although you can configure a macro for the Ctrl S  Cmd S on Mac  keys to format the code and save it   Intellij reformat on file save

The way I implemented automatical reformating like in Microsoft Visual Studio  It doesn t work perfect    1  Edit  gt  Macros  gt  Start Macro Recording 2  Press continuously  Enter   Ctrl Alt I 3  Edit  gt  Macros  gt  Stop Macro Recording  Name it for example ReformatingByEnter    Now we need to perform same actions but for Ctrl Alt L    4  Edit  gt  Macros  gt  Start Macro Recording 5  Press continuously      Ctrl Alt I 6  Edit  gt  Macros  gt  Stop Macro Recording  Name it for example ReformatingBy     Now we need to assign HotKeys to these macros   7  File  gt  Settings  gt  Keymap  gt  press on a gear button  gt  Duplicate    8  Unfold a macro button  beneath  and by right clicking on two  ours macros assign HotKeys for them   Enter  and     correspondingly
