How do I embedd an addon?

[Wimpface]

I want to create my own suite, such as TukUI. He's inspired me a lot by his own UI, and it feels like it'd be a fun project to have.

I've run into a problem right off the bat though, how the flippin' fudge do I embedd oUF into my !blablaUI addon? As far as I can see from scanning Tukz github files I'm doing nothing wrong, every module so far loads except oUF, and I get an error that my layout couldn't find "global oUF" when creating a tag.

I've basically just dropped oUF into an "embedd" folder and then added it's oUF.xml to my own .toc file. I don't see what I'm doing wrong though.

I can throw up my !blablaUI addon folder if needed.

Thanks for help in advance!

Do you have the oUF global specified in the .toc?

## X-oUF: oUF

Tukui.toc does it this way.

EDIT: You may also use the oUF in the namespace, without any global at all.

local parent, ns = ...
local oUF = ns.oUF

I added it, but I was ingame and I just reloaded. Quite sure I have to restart WoW for changes to the .toc file. Brb!

EDIT: Right, it worked now. All of a sudden a new error shows up but I can solve this myself I think.
Thanks Cargor! I feel really stupid now.

EDIT2: I spoke too quickly, seems the error I got blocked this error from happening, or something. It still can't find "global oUF". I'll post the whole error here.

Message: Interface\AddOns\!haoriUI\unitframes\Layout.lua:55: attempt to index global 'oUF' (a nil value)
Time: 08/21/10 19:45:57
Count: 1
Stack: Interface\AddOns\!haoriUI\unitframes\Layout.lua:55: in main chunk

The code for my "!haoriUI" can be found here, well, a download to the entire addon since there are a few files and the embedd etc. Too lazy to get a github up yet.

You should load oUF in your xml-file before your oUF layout

Doh! Trying this!

EDIT: Same error. :/

[Wimpface]

Got an svn thing set up to view my code easier, no download required anymore.

Still isn't working, it's probably some retardedly stupidly small, easy thing that I'm missing.

Hmm, I don't see any mistakes. Maybe you could add a print() on top of oUF.lua to see if it actually gets loaded.
And try if the namespace-oUF is available as I posted above.

Maybe this helps to narrow down the error

I'll add a print, I don't know what this namespace thing is and how/where to add it though. :/

EDIT: The print implies oUF is loading, I've not tried the namespace thing yet as I don't know how it works. I now get an error from oUF in the chat frame, saying:
"oUF: Error: !haoriUI is doing it wrong and settings its global to oUF."

Ah, well, at the top of your file. These namespaces are some compromise between global and local variables - think 'local to your addon'.

Each file of your addon gets delivered some arguments via "...":
#1: the name of the addon (here 'parent')
#2: a table specific to your addon (the 'namespace').

oUF normally does the same thing and then adds itself to the namespace-table, so you can access it via 'ns.oUF" even if you don't have a global defined.

---
@your global-'error': Then go the namespace-route and remove the global, it's probably better this way. I wonder if the message comes in TukUI too or if he patched it out.

EDIT: with 'file' I mean each file which uses oUF, so: your layout :P

[Wimpface]

I can't really remove the global from my layout, since the error fires on "oUF.Tags" - Where I create a health display for my unitframe.

So I would add

local parent, ns = ...
local oUF = ns.oUF

to the top of my layout file?

EDIT: I don't even know what I'm trying to say here. Re-read your post and it makes a little more sense now, I just don't know how to go about doing this. Where do I add the 2 lines of code seen above and should I do "ns.oUF.Tags" later instead?

[xConStruct]

Yep.

It works now, but the chat error remains. I'll stick with it for now and when I'm more experienced with this I'll patch it out.

Thanks a bunch Cargor!

The global-part is located at the bottom of ouf.lua:

if(global) then
	if(parent ~= 'oUF' and global == 'oUF') then
		error("%s is doing it wrong and setting its global to oUF.", parent)
	else
		_G[global] = oUF
	end
end

So, it errors out if you register it as a global 'oUF', but your addon is not oUF. Either remove the X-oUF-part in your .toc (it's no longer needed with namespaces) or choose a different global name, e.g.:
"x-oUF: My_oUF" would store oUF in "My_oUF".

Removing it then, thanks a bunch Cargor. I really appreciate the help!
