command-prompt viewscreen may affect command execution if they are
looking for UI state. To make commands execute simillary to hotkeys or
console commands the viewscreen needs to removed from the top position.
Fixes#1194
* 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 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.
* Paint, filter, and brush state is now saved between calls.
* Added 'all' paint option to set material, shape, special, and variant at
the same time.
* Added tiletypes-here (like liquids here, except is uses the saved brush
settings)
* Added tiletypes-here-point (like liquids here, always only the tile under
the cursor)
* Added tiletypes-command: runs tiletypes commands seperated by ';' tokens
(affects saved state)
* Make the internal workings match liquids a bit more
* Give brush objects a descriptor string
* Make Core::cheap_tokenise available
- 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.
The idea is that if you have to execute many RPC calls, it is
faster to suspend once. The service class takes care to auto-resume
in the destructor in case the client just disappears.
This is an incompatible change to the plugin ABI.
The Console is not thread-safe unless used indirectly
via color_ostream_proxy, so everything should use their
per-thread stream.
