then again, if you have nine games from 3 publishers all depending on the same common element, you will inevitable run into the situation where 4 of them need version 15 of that component, and the other 5 need version 16.

So while it's nice for you to make reusable components, it might be for the best if you actually drag a copy into each individual style folder and publish individual game ZIPs which have'everything that game needs'

code:

---

if not package.commonFunction then
    -- The dependancy I was relying on is missing!
end

---

code:

---

local P = {}
Deck = P
local requestedVersion = versionRequest.Deck
setfenv(1, P)
if requestedVerion <2 then
    function Deck.someFunction()
        -- This function is only exported when the requestedVersion is less than 2
    end
elseif requestedVersion >= 2 then
    function Deck.someFunction(someNewParameter)
        -- This function is only exported whn the requestedVersion is 2 or greater
    end
end

That's fine for newer code being able to use older common packages, but not for old code to continue working after the package it depends upon has moved on... especially likely if the package is 3rd party (from your perspective)

but only if you wrap every single call, and then what do you do when a mission-critical function is not available?

Nah, you're confusing the procedure structure with that of non-prototyped languages.

That is one of the advantages of the file-scoping in Lua. As it first includes the file it has its own local scope (it's actually a closure), so when I declare a variable as 'local xx = xx' it takes xx from the global scope (which is common to the calling script) and assigns it to a local variable.

Then the setfenv command is actually creating a new global scope that only applies to this file. Thus all the variables from outside the file are now inaccessible (unless I linked them to a local variable *first*).

Then, I test the version requirements and export the methods required. No matter how many different versions I have in there, only the versions required are exported, and only the exported functions are called externally - through the use of the Deck class that I defined in the calling global scope at the start.

So those tests are ONLY done when the 'class' is initialised - Not even when instances are created as they use a recursive parent calling method to gain access to the class.

It'll be executed once and only once for an entire application. Thus you set the required version of this class before you 'require' it.

In this way, you can fail at application load if the version required is not available - or more specifically, if it can't honour the interface of the requested version - which would only happen if your library is too old, assuming you keep your old interfaces available.

It is added to the 'funpack' log window, and also to the main chat window.

Since I'm not a big fan of flooding the chat window. Is there anyway you could make it only send to the funpack window? Also could you enable the funpack window for the general user. Though I know the switch to enable it, the average user/developer does not. Perhaps add a new flag in the toy's options, "Debug Mode" which would enable such a thing? Also then we could put a test in our code "if in debug mode, output these useful bits." Rather than modifying the code to do it. Especially since in the future you will hopefully be doing some CRC/etc on the toy's code so that players have to use the same version... then the developer could switch on debug mode without upsetting that.
TA_IsDebugMode()
-or-
TA_GetDebugLevel() -- returning things like OFF, LOW, MEDIUM, HIGH, etc.


Also a TA_SetMod or TA_GiveMod may be useful in some circumstances. Say when someone that is not playing gets ahold of mod, perhaps the script could attempt to enforce that only people currently playing may have mod? Not too sure about that one.

Also, I don't suppose you can give us something that would allow for better usage of text? Something like...if I write this string, how much space will I need? I have a work around, but it's expensive and not pretty, using the evil TA_GetPixel function. Java has something that can get such Font-Metrics, does MSC++ have such a thing?

I know I've asked for this before, but your flip-flopping between colorIndex and RGB is a pain in my....side. Can't you standardize on one rather than flip flop? Or will you PLEASE give some conversion functions. Also it is not always clear in your documentation which is called for....

[heh Good suggestions and I plan to do them all -s]
