Script Compiler to only recompile when changes are made
Even though this isn't really necessary since through out my tests it only takes around 10 seconds to compile the scripts anyway I thought I'd share this. This modification to Compile will check for newer or altered scripts (both .cs and .vb) throughout your scripts folder and cache the script file names to 2 files ScriptCountCS.cnt and ScriptCountVB.cnt to make a quicker comparison for the sebsequent loads. If it finds a Scripts.CS.dll or Scripts.VB.dll in your Scripts\Output \ folder it will first check to see if your script folder has any scripts (for shards that don't want to upload their scripts), if it does have scripts, it will check for newer files and it will load the compiled DLLs if no newer files are found. You can see the timing when you run the server in -debug mode. Even though I used plenty of exception handling and feel this code is safe: USE AT YOUR OWN RISK
Just replace the whole compile (bool debug) function
Code:
public static bool Compile( bool debug )
with the following code.
PHP Code:
private static bool CacheScriptNames(string type, bool debug)
{
string[] files = GetScripts( type );
return CacheScriptNames( type, files, debug );
}
private static bool CacheScriptNames(string type, string[] files, bool debug)
{
DateTime dt = DateTime.Now;
TimeSpan dt1 = new TimeSpan();
if (File.Exists( string.Format("ScriptCount{0}.cnt", type == "*.vb" ? "VB" : "CS" )))
{
int size;
string[] CachedScripts;
FileStream fs = null;
BinaryReader r = null;
try
{
fs = new FileStream( string.Format("ScriptCount{0}.cnt", type == "*.vb" ? "VB" : "CS" ),FileMode.Open, FileAccess.Read );
r = new BinaryReader(fs);
size = r.ReadInt32();
CachedScripts = new string[size];
for (int i=0;i < size;i++)
{
CachedScripts[i] = r.ReadString();
}
r.Close();
fs.Close();
if (debug)
Console.WriteLine("You have {0} {1} script files cached.", size.ToString(), type == "*.vb" ? "VB.NET" : "C#" );
