Go to Window -> Preferences -> Scala -> Formatter -> Miscellaneous, then tick "Rewrite arrow tokens"

You can then type => and it will be converted to ⇒ when you do an auto-format (Ctrl-Shift-F), and similarly for <- to ←

It doesn't seem to convert -> for some reason, though.

You may get problems (on Windows, at least) with the character encoding of the file - you may need to change this to UTF8 via the file's Properties dialog.

  • It is also possible to enable automatic formatting on save at Java -> Editor -> Save actions. Works for .scala files but doesn't work for scala sheets. – Anton Kuzmin Apr 12 '14 at 03:26
