In some situations (e.g. 32-bit Linux), "intptr_t" is defined as "int", which is
equivalent to "int32_t", leading to issues with duplicate definitions. In other
situations with GCC, "intptr_t" is "long", which isn't covered by any intNN_t
types. Also, definitions for "long" already had to be added on Windows, because
no fixed-width types in MSVC are equivalent to "long".
Switching to non-fixed-width types should hopefully cover all of these
situations. If this doesn't cover any integer types that we need, it will
be caught quickly, e.g. by references to integer_traits<T> in LuaWrapper.cpp.
- This context requires core suspend lock and asserts it in a few places.
- Special 'event' objects are introduced. They can be invoked as
functions, in which case they iterate all their fields and call
them as functions. Errors are printed and consumed.
- When a plugin is opened by the core context, events registered in
a special array are linked to it. The system is organized so as to
avoid even trying to pass the event to lua if the module isn't loaded.
- To ensure reload safety functions have to be wrapped. Every call
checks the loaded state and locks a mutex in Plugin. If the plugin
is unloaded, calling its functions throws a lua error. Therefore,
plugins may not create closures or export yieldable functions.
- The set of function argument and return types supported by
LuaWrapper is severely limited when compared to being compiled
inside the main library.
Currently supported types: numbers, bool, std::string, df::foo,
df::foo*, std::vector<bool>, std::vector<df::foo*>.
- To facilitate postponing initialization until after all plugins
have been loaded, the core sends a SC_CORE_INITIALIZED event.
- As an example, the burrows plugin now exports its functions.
