A super crappy and kinda slow (it makes network calls!) Visual C++ demangler script for Hopper disassembler. Based on https://github.com/melomac/Hopper/blob/master/Demangle%20Swift.py, uses demangler.com

HopperVCppDemangler.py

import urllib, urllib2

def demangle(symbol):
	r = urllib2.Request('http://demangler.com/raw', urllib.urlencode({'input': symbol}))
	response = urllib2.urlopen(r)
	return response.read()

def main():
	doc = Document.getCurrentDocument()
	current = doc.getCurrentAddress()

	for index in xrange(doc.getSegmentCount()):
		seg = doc.getSegment(index)

		for address in xrange(seg.getStartingAddress(), seg.getStartingAddress() + seg.getLength()):
			name = seg.getNameAtAddress(address)

			if name is None:
				continue
			else:
				demangled = demangle(name)

			doc.moveCursorAtAddress(address)

			if name is demangled:
				doc.log("Failed to demangle symbol at address: 0x%08x with name: %s" % (address, name))
				continue

			seg.setNameAtAddress(address, demangled)

	main()
