variable name change [request] about synchrony HOT 5 CLOSED

Changing variable names is a feature I could implement but manual variable renaming is much faster and more reliable (with VSCode you can select a symbol and press f2 to change the var name and all references)

Other idea is remove function used to decript

Afaik setting removeReferences will remove the functions

from synchrony.

I find that first automatically renaming all the variables to something shorter is very helpful, since you can get a better quick overview and see what variables are the same at a glance before doing the manual renaming.

the only issue is use "global" value check, instead rename only inside function (local) i mean it do like this:

function A1(a,b) { 
  var c = 1+2;
  var d = 3+ 4;
  return c+d+a+b
 }
 
 function B1(f,g) { 
  var h = 2+2;
  var i = 6+7;
  return h+i+f+g
 }

when should be

 function A1(a,b) { 
  var c = 1+2;
  var d = 3+ 4;
  return c+d+a+b
 }
 
 function B1(a,b) { 
  var c = 2+2;
  var d= 6+7;
  return c+d+a+b
 }

Then is more easy overview changes and make diff cause you have always same "local variables" name, because if you add new function between A1 - B1, it will use new variables name

This has been implemented in 2.0.1

Variable renaming is a lot easier (you can do it from the deobfuscator web ui because it uses monaco (vsc's editor), by pressing f2 after selecting a symbol.

however there are plans to implement automatic identifier renaming with type inference in an upcoming version

from synchrony.

implemented in https://github.com/relative/synchrony/releases/tag/2.3.0.

update with npm i --global [email protected] and run
synchrony deobfuscate --rename ./file.js
