If you want to have it on a key, then you need to have a
function for it, something like this (room for improvement):

  define par_format_paragraph ()
  {
     variable tmpfile = make_tmp_file ("par_tmp");
     variable str = "", fp, wrap = WRAP;
     
     bol_skip_white ();
     ifnot (eolp ())
       backward_paragraph ();
     push_mark ();
     forward_paragraph ();
     str = bufsubstr_delete ();
     () = write_string_to_file (str, tmpfile);
     fp = popen ("cat $tmpfile | par -w$wrap"$, "r");
     str = strjoin (fgetslines (fp), "");
     () = pclose (fp);
     () = delete_file (tmpfile);
     insert (str);
  } 
  
What you have in Jove can be achieved with ishell from jedmodes:
