Python method for formatting compressed JS files

This article illustrates how Python formats a compressed JS file. Share with you for your reference. Specific analysis is as follows:

The script can be compressed js file format on some restore, of course, not 100% perfect, temporarily do not deal with the syntax problem, just to facilitate the reading of js code

lines = open("unformated.js").readlines()[0].split(";")
# Generally compressed file all the code in a line 
# Set the index as the case may be 0 The line is the source code. 
indent = 0
formatted = []
for line in lines:
  newline = []
  for char in line:
    newline.append(char)
    if char=='{': #{  That's the basis of the indentation 
      indent+=1
      newline.append("n")
      newline.append("t"*indent)
    if char=="}":
      indent-=1
      newline.append("n")
      newline.append("t"*indent)
  formatted.append("t"*indent+"".join(newline))
open("formated.js","w").writelines(";n".join(formatted))
