Getting Editor Material Suffixes

[reepblue]

I'm trying to create an extension that'll allow quick material generation by right clicking on the image and selecting "Convert Image to DDS". The documentation with String:Right for lua isn't right and I think it's better that the extention should get the suffixes from the editor's config. 

Because of limited documentation on the addon system, how would I do this?

The bad code is commented out for now.

    if event.id == EVENT_WIDGETACTION then
        if event.source == extension.menu[1] then
            if program.assetbrowser.selectedfile then
                if program.assetbrowser.selectedfile.package == nil then                    
                    local imageext = string.lower(ExtractExt(program.assetbrowser.selectedfile.path))                  
                    if imageext == "png" then
                        local file = StripAll(program.assetbrowser.selectedfile.path)
                        --[[
                        -- TODO: Get the conversion suffix from the editor.
                        if string.right(10, file) == "_normalmap" or string.right(7, file) == "_normal" or string.right(4, file) == "_dot3" or string.right(2, file) == "_n" then
                            extension.ToTexture(program.assetbrowser.selectedfile.path, ".dds", TEXTURE_BC5, true)
                        elseif string.right(13, file) == "_displacement" or string.right(7, file) == "_height" or string.right(5, file) == "_disp" or string.right(2, file) == "_h" then
                            extension.ToTexture(program.assetbrowser.selectedfile.path, ".dds", TEXTURE_RED, true)
                        else
                            extension.ToTexture(program.assetbrowser.selectedfile.path, ".dds", TEXTURE_BC7, true)
                        end
                        ]]
                    end
                end
            end
        end

There is no string class in the table of contents. That page is not listed anywhere.

You want the Lua string library:
