Fix indexing primitive refs with integers (broken in #1543), add tests
Apparently lua_tostring has the side effect of *converting* numbers to strings

lethosor df6f3a0455 Mark ref_target as a metafield so meta_primitive_newindex fails properly
unit:_field('hist_figure_id').ref_target = 4 now fails with "Cannot write field int32_t.ref_target: builtin property or method" instead of "not found"

more useful description

lethosor 0332a5c25a Replace a call to abort() with a VTableMissing exception
This makes some scripts crash less when the viewscreen vtable is unavailable,
for example.

Alexander Gavrilov 6046d68639 Support std::fstream in data structures and add file_compressorst to xml.
One tricky thing is that fstream does not have operator=, so the new
file_compressorst requires a manually implemented one that skips it.

Alexander Gavrilov c6694e386f Add rather inefficient type_identity wrapping for std::set.
Accessing an element is O(N), as if it was walking a list.

Alexander Gavrilov 149f175909 Make primitive refs (i.e. pointers to numbers, etc) behave as arrays. 2012-06-13 22:40:39 +04:00
Alexander Gavrilov 5afe2ca002 Update dfhack for specific_ref. 2012-05-03 11:47:04 +04:00
Alexander Gavrilov 2303a25bde Implement unconstructed building instance creation and linking into world.
For more flexibility, the base api is split into 3 phases:
alloc, setSize, and construct. No support for non-actual
buildings like stockpiles and activity zones at the moment.

Alexander Gavrilov 378a1fb914 Support the '#' string as index for wrapper vector insert at end. 2012-04-17 12:15:45 +04:00
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 9384f0c842 Update lua to 5.2 and fix obvious breakage due to obsolete api. 2012-03-31 12:11:43 +04:00
Alexander Gavrilov a9b7c74a23 Allow assigning NULL lightuserdata to pointers, and export a global.
Otherwise there is no way to specify NULL via recursive lua table assign.

Alexander Gavrilov 85c91c92d8 Implement __pairs and __ipairs for DF objects.
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).

Alexander Gavrilov 929657bed4 Disable pointer auto-vivification unless new is specified.
Since it is essentially allocating non-gc managed objects,
it can lead to memory leaks and shouldn't happen invisibly.
Also support using the 'assign' key to request assign()
from another object before processing the current map.

Alexander Gavrilov b76bdad50f Implement recursive transfer of values from lua to c++ structures.
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().
