Alexander Gavrilov bd37cc09c5 Update the Lua API document with info about scripts. 2012-06-22 20:17:55 +04:00
Alexander Gavrilov 65e82f7c12 Support controllable error presentation verbosity in lua code.
Use qerror to squash stack traces and location prefix.

Alexander Gavrilov 7eb4fc19de Make dfhack.run_script usable from other scripts, and document it. 2012-06-14 12:46:12 +04:00
Alexander Gavrilov 87ec1de891 Improve lua api for tile biome access. 2012-05-13 13:58:41 +04:00
Alexander Gavrilov d4d6349f48 Expose builtin commands to dfhack-run, and add lua script support.
Move builtin command implementation to Core methods, and fall
back to hack/scripts/*.lua for otherwise unrecognized commands.

Alexander Gavrilov 4cffb6428d Update building creation code with new knowledge, and fix zone.
Also, document new lua api, and add a more convenient wrapper.

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 16ee049664 Split off the burrows api from Maps and Units. 2012-04-26 12:56:28 +04:00
Alexander Gavrilov 763a301b4f Add a few more lua api functions, documentation, and unit sort orders.
Units::getProfessionName appears to work correctly for
everything except nobles.

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
Warmist 17d5b2de04 Multiline interpreter.
To test try writing for k,v in pairs(table) do <enter> print(k) <enter> end
Also prompt could be changed (couldn't think of anything better).

Alexander Gavrilov 1e64a6a2f6 Make dfhack.lineedit automatically interact with RunCoreQueryLoop.
It still falls back to the original waiting mode if yield fails.

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 2d8611a480 Add core api for moving items between ground and containers. 2012-04-12 18:37:27 +04:00
Alexander Gavrilov 0c2b78b96b Add api for manipulating burrows to the core. 2012-04-11 19:42:05 +04:00
Alexander Gavrilov 61245711f7 Export a few maps functions to lua. 2012-04-11 16:20:16 +04:00
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 0daafef690 Wrap MaterialInfo for lua. 2012-04-06 19:56:19 +04:00
Alexander Gavrilov 903e9ee716 Export a few more functions to lua. 2012-04-06 11:21:28 +04:00
Alexander Gavrilov 9eed9f0d24 Wrap a few utility functions defined on the c++ side for lua. 2012-04-05 19:55:59 +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 2d4af4ac3e A few more utility functions for lua. 2012-04-03 20:02:01 +04:00
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.
