This adds a Lua API for representing asynchronous operations and running
coroutines based on those operations comfortably. This is very similar
to features other languages have introduced such as C# or JavaScript. In
fact, the whole "promise" thing is derived from how JavaScript
represents these operations.
This is the initial and very basic system for supporting async
coroutines in Lua. There is no native support for running these
operations at specific points (they run whenever the awaited promise
resolved) or making sure they do not leak through different game states.
This adds the capability to have a Lua script that does not need to use
our table syntax at all but instead defines the hooks by calling API
functions. This also makes it possible to add hook functions at runtime
if the script requires that.
Also clean up some unused debug stuff.
This is a system for storing arbitrary data in the config file and then
easily retrieving it later on. This has full Lua support for exposing
the available options in a custom UI and changing the values of the
options. This ported some of the existing command line options over to
the new system which is opt-in for the moment by using a mod_table flag.
This is pretty much similar to the value setting changes. This is a much
safer solution for getting values out of the scripting system which has
compile time validation for move-only types.
This commit changes the way the scripting API works by properly using
the newly available type information for moving the FSO resources into
the memory supplied by lua. This has full support for rvalue references
which will make it possible to use move-only types with the scripting
API.
This also makes the API much safer to use since it doesn't use pointers
to local values anymore which made it very hard to use the API in a
different context without causing issues.
This only covers writing the FSO values to Lua. Getting values back is
not covered yet.
This was previously used for allowing scripts to set arbitrary values on
scripting objects. However, it was used by only a few scripting
functions and, as far as I know, no script uses this features.
This removes that feature which simplifies the code ade_index_handler
of.
This also simplifies the code that handles the userdata for libraries
provided by FSO.
This maintains the type information which can be used for enforce
const-correctness and also for implementing more advanced ways of
handling the type information.
This is probably a bug from when I changed how those functions worked.
The function is supposed to return if it successfully retreived a value
from the Lua stack but instead of returning true if it was, it returned
the value it just retrieved. This works fine if that value is true but
causes issues if it was false.
This add a system for adding generic instances of the DynamicSEXP class
to the SEXP system. The only implementation at the moment is the LuaSEXP
which is used by the mn.addSEXP lua API to allow Lua to add new SEXPs.
Since this requires that FRED also runs lua scripts I added a mod table
option to enable scripting in FRED. Since the current scripts are not
built with FRED in mind it would likely break all these scripts if FRED
would be opened with normal scripting enabled.
This fixes#1320.
The iterator known as _L, besides having an absurdly poor name,
clashes with standard headers on OpenBSD -current at the time
of writing. This commit is the minimum needed to build on
OpenBSD with an updated C++ standard library.
This adds a utility library for handling all the nasty lua referencing
stuff. It also provides functions for convienent usage of lua objects
such as tables and functions which allows to use them directly from C++
code without using the ugly Lua C-API.
