before, we inhibited multiple mouse button down events by overwriting
the values in enabler. now we keep state internally and inhibit multiple
events on our own.
also add events and state tracking for middle mouse button
before, when a mouse button was held down, we'd send a single _MOUSE_L
and _MOUSE_L_DOWN event and that's it. now we properly send a single
_MOUSE_L_DOWN event and _MOUSE_L events for as long as the button is
held down. similar for the right mouse button
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.
* 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)
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.
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++.
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.
- 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.
