I wound up rebinding the Reformat code    action to Ctrl-S  replacing the default binding for Save All   It may sound crazy at first  but IntelliJ seems to save on virtually every action  running tests  building the project  even when closing an editor tab  I have a habit of hitting Ctrl-S pretty often  so this actually works quite well for me  It s certainly easier to type than the default bind for reformatting

I set it to automatically clean up on check-in  which is usually good enough for me  If something is too ugly  I ll just hit the shortcut  Ctrl-Alt-L  Return   And I see they have an option for auto-formatting pasted code  although I ve never used that

I thought there was something like that in IntelliJ  but I can t find it   The only clean-up that happens at save is that white space at the ends of lines is removed   I thought I had to specify that behavior at one point  but I don t see anything related at this point

I suggest the save actions plugin  It also supports optimize imports and rearrange code   Works well in combination with the eclipse formatter plugin   Search and activate the plugin     Configure it     Edit  it seems like it the recent version of Intellij the save action plugin is triggered by the automatic Intellij save  This can be quite annoying when it hits while still editing   This github issue of the plugin gives a hint to some possible solutions   https   github com dubreuia intellij-plugin-save-actions issues 63  I actually tried to assign reformat to Ctrl S and it worked fine - saving is done automatically now

This solution worked better for me    Make a macro  I used Organize Imports  Format Code  Save All  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    Code -   Optimize Imports      if a dialogue box appears  check the box that says  Do not show this message again    then click  Run   Tools -   Start Macro Recording  Code -   Optimize Imports     Code -   Reformat Code     File -   Save all  Tools -   Stop Macro Recording  Name the macro  something like  formatted save   In File -  Settings -  Keymap  select your macro located at  Main Menu -  Tools -   formatted save  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  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   IntelliJ 12  8  The Preferences contain the Keymap settings  Use the input field to filter the content  as shown in the screenshot
