Call commands from stacks?

I have a Livecode stack that I started copying chunks of code out of to use in a server script.
Problem is that I keep making changes to the code in the stack, and then I need to update the scripts.
Can I just include the stack and run commands out of it in a server script?

Yep: "start using" to make all handlers in a stack available as a library works on servers as well.

Interestingly, it appears that the preOpenStack handler is *not* called when you "start using" a stack. I'm not sure at the moment if this is an oversight, if I'm expecting too much out of the server configuration, or if this is by design.

True
Since HCIL the message sent to a library brought into use is libraryStack.

Yeah. I'm now dispatching to my preOpenStack handler in the card script from the libraryStack handler in the stack script in order to get a frontscript in play. I know startup will get called instead of preOpenStack in standalones, but I rather expected that the server would call preOpenStack when launching a stack. Makes it slightly harder to get a one-size-fits-all stack that works with either the desktop or server engines.

If the stack is a library "libraryStack" should be automatically called in either Server or the desktop when the stack is brought into use.

Richard- yeah, I realize that, but what I was trying to do in this case is launch a stack created with the IDE. If it were just a library I would have made it a script-only stack. The stack does have a button whose script gets installed as a frontscript, and I have been using the preOpenStack handler to insert the script when the stack is launched in the IDE. So now for the server I have added
Code: Select all
on libraryStack
dispatch "preOpenStack" to card 1 of me
end libraryStack
