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.
* 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.
Structs enumerate fields in memory order in pairs().
Containers & biftields enumerate int indexes in ipairs, and
string keys in pairs (i.e. using index-enum for arrays).
E.g. df.global.cursor = { x = 1, y = 2, z = 3 }. The lua data
must be represented by raw lua tables.
For structs, the entries in the table are assigned to matching fields.
For containers, if a 'resize' field is missing or nil, the table is
treated like 1-based lua array, and the container is resized to match
its # length. Otherwise, the field must be either an explicit number,
true or false. If it is true, the size is selected by the highest index
in the table. After that, entries are copied using 0-based indices.
For pointers, the table must match the target object. If the pointer
is null, the object is auto-allocated; this can be controlled using
the 'new' field, the value of which will be passed to df.new().
Removed t_virtual.
Made lua use C++ compiler
Removed many silly exception types from Error.h and renamed the rest.
Removed Brush classes from tiletypes plugin.
I expect the majority of methods will have to suspend the core
first thing anyway, so this will reduce typing and bugs.
Also get rid of the "me->" ugliness by splitting threadFn.
- Associate a default output stream with the whole connection.
If not explicitly specified in the constructor, uses stdout.
- Add methods that use this default stream to RemoteFunction.
- Add easily usable wrappers for CoreSuspend and CoreResume.
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.
Trader items are now inside tables, and thus not in the block
item lists. Thus it is necessary to scan the global item vector
and look up blocks by coords.
