Alexander Gavrilov 14709e5d45 Add an official core lua context, and allow plugins to send events to it.
- 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.

Alexander Gavrilov cb49c92b99 Allow plugins to export functions to lua with safe reload support.
- 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.

Alexander Gavrilov 61245711f7 Export a few maps functions to lua. 2012-04-11 16:20:16 +04:00
Alexander Gavrilov e74788cb26 Add a generic facility for object finalization during stack unwind.
Supports two modes of finalization:

- try {...} finally {...}
- try {...} catch { ...; throw }

Argument passing discipline is designed with vararg tail calls in mind.

Alexander Gavrilov 9eed9f0d24 Wrap a few utility functions defined on the c++ side for lua. 2012-04-05 19:55:59 +04:00
Alexander Gavrilov 7efbd798ce Upgrade lua errors to structures when attaching stack trace.
This allows detecting when it's re-thrown and avoiding attaching the
stack twice, and so on. Would also be useful if debugging is added.

Alexander Gavrilov afe4eba957 Improve performance of the persistent data api, and wrap it for lua.
Use an stl table for string keys to avoid linear cost of lookup.

This uncovered a bug in the new luaL_getsubtable function.
