[rkward-devel] new JS functions

[meik michalke]

hi,

i just added two new JS functions to trunk:

 - shortName()
   JS equivalent to rk.get.short.name(), i.e. turn
   my.data.frame[["var1"]] and my.list[["var1"]][["var2"]]
   into var1 and var2

 - getValueShort()
   a getValue() alternative for varslots, to get an array of
   short names directly

examples:

function calculate(){
  // read in variables from dialog
  // long way:
  var myVarslot1 = getValue("my_varslot");
  myVarslot1 = shortName(myVarslot1);
  myVarslot1 = myVarslot1.join(", ");
  echo("c(" + myVarslot1 + ")");

  // shortcut:
  var myVarslot2 = getValueShort("my_varslot").join(", ");
  echo("c(" + myVarslot2 + ")");
}

what do you think?

i put them to rkward/scriptbackends/common.js -- is that a good place? i could 
probably come up with some more functions to ease the JS coding part for 
rather common stuff. 


viele grüße :: m.eik
