A quick n' dirty hack to fix a dying GrowlVoice

How to Use

Open up Terminal.app in your /Applications/Utilities directory, then type in these commands, one after each other:

  1. Create a temporary directory for cycript:

    mkdir cycript && cd cycript
    
  2. Pull the latest cycript from cycript.org:

    curl -L https://cydia.saurik.com/api/latest/3 -o cycript.zip
    
  3. Unzip cycript:

    unzip cycript.zip
    
  4. Download fix_growlvoice.js:

    curl https://gist.githubusercontent.com/kroo/11205755/raw/fix_growlvoice.js -o fix_growlvoice.js
    
  5. Start GrowlVoice now.

    open -a GrowlVoice
    
  6. A popup window should appear about malformed JSON. Close it.

  7. Ensure cycript is executable:

    chmod +x ./cycript
    
  8. Patch the running GrowlVoice process:

    sudo ./cycript -p GrowlVoice fix_growlvoice.js
    

Each time you restart GrowlVoice, you will need to run this fix script again. Run cd ~/cycript && sudo ./cycript -p GrowlVoice fix_growlvoice.js to run the script sometime later.

/**
* A quick n' dirty hack to fix a dying GrowlVoice
*
* GrowlVoice is now officially dead: https://twitter.com/GrowlVoice/status/455931023868448768
* However, Google didn't really shut off API access (there wasn't really any to begin with);
* they slightly mangled a JSON object GrowlVoice was looking for on one of Google Voice's
* internal pages.
*
* The following is a Cycript script that will bring a dead GrowlVoice back
* to life for the moment (until Google decides to mangle things more).
*
* To use:
*
* - Download cycript from cycript.org, and extract somewhere sane
* - download this script to the same place as cycript
* - Start GrowlVoice (it will complain about malformed JSON)
* - Run sudo ./cycript -p GrowlVoice fix_growlvoice.js

@import com.saurik.substrate.MS
var oldm = {},
NSUTF8StringEncoding = 4,
MESSAGE = @selector(accountInfoFetcher:finishedWithData:error:),
START_TOKEN = 'var _gcData = ',
END_TOKEN = '};';
// It's failing in accountInfoFetcher:finishedWithData:error:, a callback method
// that parses a response from Google's auth page, and pulls in a bunch of info.
//
// Since it's failing there, let's hook it, and massage the data we're getting
// back until GrowlVoice can understand it again.
//
// Using MobileSubstrate, the following line 'swizzles' the method, replacing
// it with our own wrapper function:
MS.hookMessage(GoogleVoiceLoginInterface, MESSAGE, function (fetcher, data, err) {
// In particular, we need to find a json object embedded in the page that was
// just returned into this function (as the second arg, data).
// Convert to NSString from NSData
var sdata = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
// Find the start and end of the JSON object, then split the page into 3
// sections: before the json object, after, and the object itself. This is
// pretty fragile, but exactly what GrowlVoice does, so we might as well be
// consistant.
var startIndex = sdata.indexOf(START_TOKEN) + START_TOKEN.length;
var endIndex = sdata.indexOf(END_TOKEN, startIndex) + 1;
var prefix = sdata.slice(0, startIndex);
var suffix = sdata.slice(endIndex);
var authJSON = sdata.slice(startIndex, endIndex);
// Now, fix the JSON object. This method is robust, but dangerous:
// Google's new JSON encoding format only works when evaluating as a
// javascript statement -- it's really not even close to valid json.
// Therefore, we evaluate that line as a javascript statement, then
// re-encode back to well-formed json.
eval('var gcData = ' + authJSON);
var fixedJSON = JSON.stringify(gcData);
// reconstruct the original page, and pass back through to the original method
var newdata = [(prefix + fixedJSON + suffix) dataUsingEncoding:NSUTF8StringEncoding];
oldm->call(this, fetcher, newdata, err);
}, oldm);
// trigger the signin process again
[choose(GoogleVoiceLoginInterface)[0] signIn];

+1 not working on 10.10 with the same referenceError: Can't find variable: require. Any love for Yosemite?

I was thinking of making an Applescript to run Growl Voice and execute the command. Doesn't quite work:
do shell script "open -a GrowlVoice"
do shell script "~/cycript/cycript -p GrowlVoice fix_growlvoice.js" with administrator privileges

It returns an error
error "*** _assert(!stream->fail()):../Console.cpp(874):Main" number 1

Any thoughts on how to make a single double-clickable to launch GrowlVoice?

(this has been a helpful thread!)

@dnasralla,

If you are just wanting to avoid running the terminal command manually at each launch, then this should take care of things for you.

Hey guys, if you're trying to get this to work under 10.10 and have some time to spare for debugging, cycript author @saurik gave some pointers on how to fix this in szhu/fix-growlvoice#6.

Another update for you guys — d235j/GVFixer is a SIMBL plugin that works on 10.10 and is dead simple to set up.
