How to launch editor like vi or emacs from node.js REPL?

I want to launch an editor like vi or emacs from node.js REPL.

I have tried two approaches till now:

1. Node Addons

   Heres how my editor.cc looks like:

   const char *tempFile = "TEMP_FILE"; // File to be opened with the editor
   
   Handle<Value> launchEditor (const Arguments& args) {
       const char *editor = "vi";
       Local<String> buffer;
   
       pid_t pid = fork();
       if (pid == 0) {
           execlp(editor, editor, tempFile, NULL);
   
           // Exit with "command-not-found" if above fails.
           exit(127);
       } else {
           waitpid(pid, 0, 0);
           char *fileContent = readTempFile(); // Simple file IO code to read file.
           buffer = String::New(fileContent);
           free(fileContent);
       }
       return buffer;
   }
   
   
   // MAKE IT A NODE MODULE
   
   void Init(Handle<Object> target) {
       target->Set(String::NewSymbol("editor"), FunctionTemplate::New(launchEditor)->GetFunction());
   }
   
   NODE_MODULE(editor, Init)
   

   This worked when I had node v0.6.12 (compiled with node-waf), but when I updated node to v0.8.1, this code stopped working (compiled with node-gyp). The editor simply didn't appear, and the file content was read and returned (with emacs) or the editor was running as a background process (with vi)! Is there anything that I need to change for it to work with 0.8.1?

   Even if the editor is launched as background process, can I bring it to foreground from the code itself?

2. Child_process module

   spawn = require('child_process').spawn;
   editor = spawn('emacs', ['TEMP_FILE']);
   

   But this is not working properly. With emacs, it shows the error input is not a tty and vi gives a weird interface.

Can someone help with any of the solutions above, or suggest some other working solution?
