I don't know Notepad++, but I started a indenter plugin awhile ago, I'll
try to check where it is and make the source available if it can be
useful.  I should also finish it, but...

Unfortunately astyle does crazy stuff (like seeking back and forth) with
its input, making impossible to pipe data to it (actually it'll work
until the data size exceeds the OS's IO buffer size IIRC, but if it
exceeds that size astyle will just hang indefinitely).  Calling that
executable requires a real file then.  The plugin I talked about
previously has an astyle backend too, but it writes a temp file for the
very reason above.

So yes, AStyle can be used, but no, you can't pipe it data so it can't
be used with custom commands.   However, GNUIndent can.
