Thank you John.

PS - I enhanced 'require' to support multiple return objects for those rare cases (one so far) when I want to package two related classes in the same file.

Also, I embed the Debug module in the Require module because of the strange error I was having ('yield in C function' or something like that - its been a long time). Never had that error again after doing that. - Am I the only one who had that error?

PS - Its working fine now in Lr4b.

Thanks for sharing this John!

I did try it some time ago but had trouble getting it to fit with my

build/test environment. Next time I get some spare time I'll have to have

another go because the features do sound quite useful.

Thanks, Matt

I do.

Will try new version. Thank you.

UPD. At first glance everything seems ok.

New version of Debugging Toolkit

I've released version 1.3 of the Debugging Toolkit , which makes Debug.pp compatible with LR 4 beta. Please let me know of any issues. If anyone other than Rob uses this, drop me a note so I have some sense of usage.

It uses the following function to determine whether a value is an SDK object (e.g. LrFolder):

--[[----------------------------------------------------------------------------
private boolean
isSDKObject (x)

Returns true if "x" is an object implemented by the LR SDK. In LR 3, those
objects are tables with a string for a metatable, but in LR 4 beta,
getmetatable() raises an error for such objects.
------------------------------------------------------------------------------]]

local majorVersion = LrApplication.versionTable ().major

local function isSDKObject (x)
    if type (x) ~= "table" then
        return false
    elseif majorVersion < 4 then
        return type (getmetatable (x)) == "string"
    else
        local success, value = pcall (getmetatable, x)
        return not success or type (value) == "string"
        end
    end
