Pauli 1fc37f8ddc Checke Console::lineedit error return values
Console::lineedit can return -1 to indicate input error and -2 to
indicate the program is closing. But most users don't check possible
unusual return values which can lead to exit hang.

lethosor c44ac8ec6e Improve handling of fatal errors and errors in dfhack.lua
* Several fatal errors that occurred during core initialization didn't
  stop initialization or set 'errorstate' properly, which caused
  update hooks and other code to crash later. This has been fixed and
  should address crashes like the one mentioned in #470.
* Errors when loading dfhack.lua now cause Lua::Open() to fail, which
  triggers a fatal error in Core::Init()
* Failure to initialize the console no longer results in a call to
  fatal() (since it didn't actually stop initialization previously)

lethosor 96f3bdafb4 Implement an internal command to interrupt running Lua scripts
This inserts a debug hook that runs every 256 instructions by
default, which has a minimal impact on performance.

Alexander Gavrilov 27f169e298 Provide a partial application utility function to lua.

Alexander Gavrilov c6c5ad56c9 Track lua event listener count, and let the C++ host know.
This allows completely avoiding the call overhead if there
are none. The downside is that the event object now has to
be a userdata with lots of metamethods.

Alexander Gavrilov d4d6349f48 Expose builtin commands to dfhack-run, and add lua script support.

Alexander Gavrilov 2ef321a208 Preserve the original lua global environment for modules.
The intent is to prevent accidental pollution of module namespaces
by globals defined from careless scripts running in the _G environment.

Alexander Gavrilov 3beb2ebf25 Export the onStateChange event to core lua context & add some docs. 2012-04-17 11:45:09 +04:00
Alexander Gavrilov 1e64a6a2f6 Make dfhack.lineedit automatically interact with RunCoreQueryLoop.
It still falls back to the original waiting mode if yield fails.

Alexander Gavrilov 3e4863bc80 Integrate coroutines with table-based error handling.
Properly attach stack traces to errors passing the resume boundary.
Replaces coroutine.resume and coroutine.wrap with appropriately
modified versions, and adds a Lua::SafeResume function for C++.

Alexander Gavrilov 48e4717dd2 Try working around some msvc problems. 2012-04-16 10:59:55 +04:00
Alexander Gavrilov a1756a864c Implement a way to do prompts from core context.
The trick obviously is doing it without forcing DF to wait suspended.
Fortunately, lua has built-in coroutine support, so the interactive
prompt can simply yield and rely on the external loop to do the job.
To use this however the REPL had to be replaced with lua code.

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 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 3afed43cdb Experimental: try wrapping a dfhack api function. 2012-04-05 11:59:39 +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 81fb57a853 Add color output and input prompt support to core lua api. 2012-04-04 10:40:33 +04:00
Alexander Gavrilov 2d4af4ac3e A few more utility functions for lua. 2012-04-03 20:02:01 +04:00
Alexander Gavrilov 444377f9db Finish documenting the DFHack core lua api existing so far. 2012-04-03 13:13:44 +04:00
Alexander Gavrilov d109b6570b Add dfhack.with_suspend(f[, args...]) that calls f with core suspended.
The lock is properly removed in case of error, which is then propagated.
Just for fun, it also can be yielded from within in a coroutine.

Alexander Gavrilov edd63080b5 Only print the shortcut help once in the lua interactive mode. 2012-04-01 17:00:25 +04:00
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.
