Demand-load most modules in the commands and ui modules. # HG changeset patch # User Bryan O'Sullivan <bos@serpentine.com> # Node ID 059c6e42fc4221816e26a72bef8cf780891989ca # Parent d2994b5298fb20f87dc1d4747635b280db3c0526 Demand-load most modules in the commands and ui modules. This improves response times for a number of simple commands, as the Python interpreter doesn't end up loading modules that it never uses. There's less benefit to demand-loading in other modules.

def demandload(scope, modules):
    class d:
        def __getattr__(self, name):
            mod = self.__dict__["mod"]
            scope = self.__dict__["scope"]
            scope[mod] = __import__(mod, scope, scope, [])
            return getattr(scope[mod], name)

    for m in modules.split():
        dl = d()
        dl.mod = m
        dl.scope = scope
        scope[m] = dl
