Re: Need some help figuring out how to use a library

[Rob Cozens]

Is there some documentation on how to copy libraries from one stack to
another or can someone tell me how to do so for libSMTP ?

Without have looked at Shao Sean's example, I can only give you general thoughts:

A library stack, as traditionally viewed, is a container of handlers (in the stack script) and resources (eg: images). The handlers & resources in library X.rev are available to any control/handler in any stack that includes 'start using stack "X.rev"' before using them. (FYI, stack "X.rev" receives a libraryStack message when it is placed in use.)

Multiple stacks can be in use at any time, and their order in the message path is the reverse order of their receipt of libraryStack messages (ie: the last stack to receive libraryStack is first in the message path among stacks in use.

Here's a sample from SDB_Utilities' preOpenStack handler:

get the effective fileName of me
set the itemDelimiter to "/"
put "Serendipity_Library.rev" into the last item of it
if there is a stack it then start using stack it
else
if the platform is "Win32" then
get specialFolderPath("Documents")&"/Serendipity_Library.rev"
if there is a stack it then then start using stack it
else
beep
answer "Please install the file,"&&quote&"Serendipity_Library.rev"&quote&&"in my folder and try again."
close this stack
exit preopenStack
end if
else
beep
answer "Please install the file,"&&quote&"Serendipity_Library.rev"&quote&&"in my folder and try again."
close this stack
exit preopenStack
end if
end if
