Live updating for scripts

The moral equivalent of the live resource updater. Edit your script, save it, and have it update instantly in the game. What's not to like?

Note: This ignores .mis, prefs.cs, etc. There really isn't a good reason to live update those. It will also only update scripts for which there is no .dso, so it won't do anything in a release version (ie if TORQUE_NO_DSO_GENERATION is not defined).

Use:

In core/volume.h at line 429 add

/// Adds a file change notification callback for a function.
///@ingroup VolumeSystem
template <class U>
inline bool AddChangeNotification( const Path &path, U func )
{
   FileSystemRef fs = GetFileSystem( path );
   if ( !fs || !fs->getChangeNotifier() )
      return false;

   FileSystemChangeNotifier::ChangeDelegate dlg( func );
   return fs->getChangeNotifier()->addNotification( path, dlg );
}

In consoleconsoleFunctions.cpp at line 1808 add

void reExec(const Torque::Path &path);

change line 1895 from

if( (dsoPath && *dsoPath == 0) || (prefsPath && prefsPath[ 0 ] && dStrnicmp(scriptFileName, prefsPath, dStrlen(prefsPath)) == 0) )

to

if( (dsoPath && *dsoPath == 0) || dStrstr(scriptFileName, "prefs.cs")) //(prefsPath && prefsPath[ 0 ] && dStrnicmp(scriptFileName, prefsPath, dStrlen(prefsPath)) == 0) )

This also fixes that line so prefs files don't generate dso's

At line 2112 after #endif add

if (compiled) //if this is true TORQUE_NO_DSO_GENERATION must be defined and it must not be prefs / .mis
      {
         Torque::Path path(scriptFileName);
         Torque::FS::AddChangeNotification(path, &reExec);
      }

And at 2138 after the function add

void reExec(const Torque::Path &path)
{
   //we know this is a file that exists, and a .cs file, so we can skip a lot of checks...
   CodeBlock *newCodeBlock = new CodeBlock();
   StringTableEntry name = StringTable->insert(path.getFullPath().c_str());

   void *data;
   U32 dataSize = 0;
   Torque::FS::ReadFile(name, data, dataSize, true);

   newCodeBlock->compileExec(name, (char*)data, false, 0);

   delete [] data;
}

Enjoy!
