How to share code between script-scope things?

[davidchisnall]

[ Slightly simplified version of my problem: ]

I have two targets in the same file that both run some code in an on_load method. Is there a way that I can declare variables that are visible in both of their on_load functions? I've tried declaring them at the global scope in the file, but that's declaration scope and so doesn't work.

use memcache

target("foo")
    on_load(function (target)
        import("core.cache.memcache")
        memcache.set("cachename", "key", "value")
    end)

target("bar")
    on_load(function (target)
        import("core.cache.memcache")
        local memcache.get("cachename", "key")
    end)

use target:data()

target("foo")
    on_load(function (target)
        target:data_set("key", "value")
    end)

target("bar")
    on_load(function (target)
        import("core.project.project")
        local foo = project.targets()["foo"]
        local value = foo:data("key")
    end)

use single script file

target("foo")
    on_load(function (target)
          import("load_module").load_foo(target)
    end)

target("bar")
    on_load(function (target)
          import("load_module").load_bar(target)
    end)

load_module.lua

function load_foo(target)
    _g.key = "value"
end

function load_bar(target)
    local value = _g.key
end

you can also use memcache in this file or use global lua variable

Thanks. The second and third of these are both useful for me in different contexts.

I find that I repeat a lot of import directives in functions. It would be nice if I could do something at the top level in declaration scope in a file to define a set of imports that are added to all script-scope things in the file.

I have also been unable to make the target:set work with objects, so I ended up having to set my object as a bunch of properties. I vaguely remember being able to do something like {expand=false} as a third argument, but I wasn't able to make that work this time.
