7224 :: JS isIndirect template excluding skVar

• ElegantBeef (orginal) [2020-12-08T02:27:58+01:00] view original

  Hello, as playing with the JS generation I've found that something as simple as the following Nim code exports the following JS.

  import jsffi
  var t = jsNull
  t = newJsObject()
  Run

  
  var t_gensym = [null];
  t_gensym[0] = {};
  Run

  I am just wondering if this is expected behaviour for the output or if skVar should be apart of the set?

  It took me a second to understand what you were complaining about. You need var to be like that so you can use it as a pointer, that includes var T arguments. You could elide it somehow based on its usage but I doubt it's too much worth it for the complexity.

  Emulating addr can be costly. (So much for the "efficiency" of pointers.) But it mostly affects global variables, for local variables we perform an analysis if the address is taken.
