需要正则表达式来修复Construct 2.8无名称

Question

在Construct 2.8字段变得无名，我需要一个可以或多或少自动翻译的脚本，类似于2to3 python脚本。为了完全披露，我是维护者。这不仅适合我，也适合整个社区。

需要翻译的内容：

ULInt32 -> Int32ub  (actually its from {U,S}{B,L}Int{8,16,24,32,64})
field("name") -> "name" / field
Struct("name", ..., ...) -> "name" / Struct(..., ...)

(still adding...)

我之前使用的正则表达式工具：

#!/usr/bin/python3
import re, os, sys

def processfolder(top): 
    for root, dirs, files in os.walk(top):
        for f in files:
            if f.endswith('.py'):
                processfile(os.path.join(root, f))
        for d in dirs:
            processfolder(os.path.join(root, d))

def processfile(fname):
    print(fname+'... ', end='')
    with open(fname, 'rt') as f:
        txt = f.read()
    txt = re.sub(r'???', lambda s: s.expand(r'\1'), txt)
    with open(fname, 'wt') as f:
        f.write(txt)
    print('done')


processfolder(sys.argv[1])
