I'm trying to restart a script trough code...

I was thinking, because Plus restarts the script when it detects changes, I would change the script, through my own script
So I open the script, write a nullstring, and close it again...
Theoraticaly it should work, it also works when I open in notepad
But I can't seem to open the file, because it is "in use" or something

Can anyone help me?

I have this code so far:

code:

---

function Restart () {
   try {
      var File = fso.OpenTextFile(MsgPlus.ScriptFilesPath + "\\Main.js", 8, 0, -1)
      File.WriteLine("")
      File.Close()
   } catch {
      //Couldn't restart...
   }       
}

---

code:

---

var File = fso.OpenTextFile(MsgPlus.ScriptFilesPath + "\\Main.js", 1, 0, -1)
var Lines = File.ReadAll().split(/\r\n?|\n\r?/)
File.Close()

---

Quite easy to understand, since Plus! is using the contents of the script to run it, and you're trying to modify your script from the script itself.

That's what I thought at first, but I still can change it in notepad (said that in the first post too)
So it should be possible

Not to mention this wouldnt work at all in a script unless the user had debugging options enabled (which is disabled by default), as only then is the script actually reloaded when its changed.

Couldn't you just clear all the variables (set them to default) then call OnEvent_Initialize?

No it doesn't, I tried it and it works when I have debuggin disabled...

I also made a new script, which has only the restart bit when I type '/restart', and a toast when it restarts. This works...

code:

---

function OnEvent_Initialize (MessengerStart) {
   MsgPlus.DisplayToast("Test", "Script loaded")
}
function OnEvent_ChatWndSendMessage (ChatWnd, Message) {
   if (/^\/restart/i.test(Message)) {
      var fso = new ActiveXObject("Scripting.FileSystemObject")
      try {
         var File = fso.OpenTextFile(MsgPlus.ScriptFilesPath + "\\Update.js", 8, 0, -1)
         File.WriteLine("")
         File.Close();
      } catch {
         MsgPlus.DisplayToast("Test", "File in use")
      }
      return ""
   }
}

Originally posted by Scripting Documentation > Getting Started > Scripting Environment
When debugging option are enabled, if a script file is modified by an external application, the script is automatically reloaded to apply the changes. This means that every time you save your script, you instantly see the changes without having to perform any extra manipulation. Note however that in order to avoid any possible kind of confusion, this functionality is disabled while the script editor window is displayed. Also, remember that this feature is only intended to be used by developers, this means that you cannot rely on it for public use of your script (so don't code a feature that expects code file changes to be intercepted by Messenger Plus!).

@Phalanxii, no, I can't. I'm working on an autoupdate, it installs with a .plsc, but sometimes the script isn't reloaded, so I need to do it in my script

First of all a very important note in regards to script updating

You should not be using the method explained below (or any other method to restart a script for that matter) to clean up old deprecated files in a subsequent update of your scripts! Unpredicted things can happen, and it is also a more complicated and longer piece of code than needed for this purpose....

Instead you should simply stick the next snippet in the script file you want to remove so that it is the only thing it contains:
(but dont forget to change the filename in it of course)

js code:

---

var fso = new ActiveXObject("Scripting.FileSystemObject");
try {
    // Replace 'todelete.js' with the file name this snippet is in.
    // In other words, if you want to remove the file 'hello.js',
    // then replace 'todelete.js' with 'hello.js' and add this entire snippet in 'hello.js'
    fso.DeleteFile(MsgPlus.ScriptFilesPath + "\\todelete.js");
} catch(e) {}

js code:

---

ReloadScript("Background Changer");

And once again, the day was saved by CookieRevised! (hmm, reminds me on the Powerpuff Girls)

Please note that restarting scripts is a feature suggested in the Scripting API Wishlist thread.

Thanks Cookie, I managed to get my piece of code working, but this is a better solution
I said fso was a declared FileSystemObject... well, it wasn't
I tried that function in a test script, and it worked. So I copied it to my main script, but forgot the declaration
Also I didn't wrote 'something' to the file, I added a nullstring to the end... So it would open and close as if it were changed, and thus restart... anyway, yours is better

@Saralk, I believe it was a suggestion of me... Because there is no clean way of restarting it
