I'm using a Notepad++ macro to 'Trim trailing and save' files. And I have setup to [Ctrl]+[S] hotkey.
But, sometimes I'm editing files that I need to keep their spaces. Is it possible to set up a macro only for some file extensions? Or there is another way to auto apply Trim trailing spaces on save only for some file extensions?
Note: I use Notepad++ to edit php files but also MarkDown files that need blank spaces at the end of some lines.
Update: I'm using Notepad++ for Windows.
