Mastiff's at it again - LUA help, please!

[Mastiff]

This will be a long night, I fear... I like to start with whatever I believe will give me the most problems, and sure enough... I'm trying to get the new NetRemote Feedback LUA to work, but where to put it? It's not working in the main directory, and creating a directory below Girder, called LUA, doesn't work either. Or does it? I try to fire this command:


NetRemote.SendLabel("PowerState", GirderPowerState)

The error message is:

[string "Z:\Kopi av Kino.GML:\NetRemote og stua\Pana..."]:10: attempt to index global `NetRemote' (a nil value)
stack traceback:
[string "Z:\Kopi av Kino.GML:\NetRemote og stua\Pana..."]:10: in main chunk


As always, help will be appreciated, and even more if it comes without the (probably well deserved) intro: "You moron, you should know that..." :roll: :wink:

[Rob H]

Put it in the luascript directory then use

require("NetRemote Feedback") in any script that needs feedback

[Mastiff]

Thanks, Rob! Now it's free to really confuse me! :oops:

[Rob H]

What version of G4?

[Mastiff]

Latest, Alpha 17 from May 13.

[Rob H]

Strange, it's working here with that version - there's nothing wrong with that number.

Unless it's a localisation issue? What do you use in Norway to indicate a decimal point?

[Mastiff]

A comma.
Edit: And you're right. Thanks! Changing that to a dot and restarting Girder fixed that problem. Is that something that can be fixed in Girder/LUA, or do I have to remember to change decimal sign on every computer?

So I'm at the next one:

Loading NetRemote Feedback.lua
LOAD
Varmepumpen står på 1
Setting PowerState to "1"
[string "Z:\Kopi av Kino.GML:\NetRemote og stua\Pana..."]:14: attempt to call global `RegSetStringValue' (a nil value)
stack traceback:
[string "Z:\Kopi av Kino.GML:\NetRemote og stua\Pana..."]:14: in main chunk

Something tells me that the synthax for setting values to the Windows registry are different in LUA 5. Gotta check that.

[Rob H]

Okay, try changing the '.' to a comma at line 633, and maybe put a space after the number and before the real comma

[Mastiff]

Eh...how do I find line 633? It takes a while to count... :wink:

[Rob H]

That's one for Ron.

It's certainly a bit worrying

[Mastiff]

Talk about crossposting!

[Rob H]

Eh...how do I find line 633? It takes a while to count... :wink:

That was for NetRemote Feedback, not the problem you currently have.

For your current problem take a look in the help for Lua Scripting, and follow the link to the Registry object

[Mastiff]

Thanks! And I know that it was for the feedback, but I think I'll just stay with the . as the decimal point for now, at least until Ron says something about this.

[Rob H]

What are you using to edit Lua files?

I use SciTE from http://www.scintilla.org

[Ron]

Okay help me out here what is the problem?

[Mastiff]

Well, I have tried... As usual I think I need it spelled out for me the first time... This is what I have arrived at so far, from the help file:

RegObj = win.CreateRegistry ('HKEY_LOCAL_MACHINE', 'Software\\Varmepumpe\\PowerState\\', GirderPowerState, Create = 1)

But it complains that:

`)' expceted near `='

And as usual I'm stumped... I'm just tring to write the Girder variable GirderPowerState to the registry key shown...

[Mastiff]

This crossposting is making me crazy! Ron, that one was for Rob. For you: A comma as a decimal point (instead of a dot) breaks Rob's NetRemote Feedback.

[Rob H]

That should just be


RegObj = win.CreateRegistry ('HKEY_LOCAL_MACHINE', 'Software\\Varmepumpe\\PowerState\\', GirderPowerState, 1)

[Ron]

That's why you should not post 2 questions in 1 thread :-)..

Numbers must use the dot, don't use the comma.

[Mastiff]

Thanks. Almost there... This creates the registry "subbranch" (don't know what they are called) PowerState below Varmepumpe, not the value PowerState = 1 or 0 in the branch Varmempumpe.

[Rob H]

The thing is that NetRemote Feedback.lua does use the dot but still gave an error in http://www.promixis.com/phpBB2/viewtopic.php?p=118587#118587

I'm not entirely sure what Tor changed to get it to work.

[Ron]

Weird. Don't tell me Lua uses localized numbers.

[Mastiff]

Rob, I changed to the dot under localized settings.

Ron, it didn't with version 4, at least. Because I have never had that problem before.

[Ron]

Thanks Mastiff, so it does use localized numbers, adding to todo list. So that it does not.

[Rob H]

Thanks. Almost there... This creates the registry "subbranch" (don't know what they are called) PowerState below Varmepumpe, not the value PowerState = 1 or 0 in the branch Varmempumpe.

Okay. You probably want something like



RegObj = win.CreateRegistry ('HKEY_LOCAL_MACHINE', 'Software\\Varmepumpe\\', 1)
RegObj:Write("PowerState", GirderPowerState)
RegObj:CloseKey()
RegObj:Destroy()

[Mastiff]

Thanks, Rob! And this is just the start of my weekend... To bad I need such a long thing for a simple registry write? It will be a lot of manual replacing in my scripts...


But good night for now!

[Rob H]

Weird. Don't tell me Lua uses localized numbers.

Yeah, certainly looks like it. Not a great design decision is it!? One would hope there's a way to turn that off

[Rob H]

Thanks, Rob! And this is just the start of my weekend... To bad I need such a long thing for a simple registry write? It will be a lot of manual replacing in my scripts...

Well you could always create a RegSetStringValue function that wraps all of that up.


But good night for now!

'night

[Ron]

Not smart of Lua indeed. There is a way in Windows - SetLocaleInfo.

edit. SetLocale is no good.

[Mastiff]

Rob, didn't reach the bed in time for that one... He-he... Functions... That means an external LUA file, right? :oops:

[Rob H]

But won't that screw up localisation of date handling?

[Mastiff]

At least for NetRemote that's possible to set on the clients, right?

[Rob H]

Good point

[Mastiff]

Woops...there's a much easier way to set the registry:

r = win.RegSetStringValue ("HKEY_LOCAL_MACHINE", "Software\\Varmepumpe","Horisontal dyse", GirderHorisontal );

[Rob H]

Ah, missed that one!
