add better handling for `readonly` to prevent bugs from `const`-ifying the return value of a member variable (e.g., unexpected copy semantics)
add more tests and add a few more handlers for new readonly type
fix simple_usertype_metatable's handling of newindex and index when not at the top level
Slight breaking change, but at the source level almost nothing changes (ipairs is the only thing that changes because for some reason it checks if what is passed is a table and that really doesn't make any fucking sense)
Closes#195Closes#196
More documentation on how things work.
Once more at a 'feature-complete' state. Continue to work on #116.
Add testcase to ensure #108 is fixed. Then, prep release.
sol::this_state is a transparent argument that gets the current state at any position in any callback
sol::variadic_args allows a person to get something that can reference the "rest of the arguments", though it doesn't enforce that it has to be the last argument
Closes#57Closes#59Closes#60
usertype now respects factory functions and does not make default constructors/destructors unless the compiler says its okay
new and __gc functions can be overridden for usertypes to provide handle-like creation and deletion functions
Overloading match fixes
RAII improvements for all usertypes
Added tests to make sure these features stay
`set_function`/`set_usertype` now properly use `set`
For the time being, we are going to avoid implementing `traverse`; aside from performance of nested table access (e.g. `int x = lua["a"]["b"]["c"]`), it's a pain. ;~;
additional tests to make sure pass-by-value and copy semantics work as intended
new proxy_base class to reduce code duplication
update function / protected_function usage (to solve starwing's issue while keeping code as clean as possible)
sol::object had a few reference leaks in the way it retrieved values: it now does it properly without leaving the stack at +1 item
sol::stack was drastically cleaned up, with the following key change:
* sol::stack::push now returns an integer of the number of things its pushed (usually 1, but can be more) (Thanks, @PrincessNyanara!)
* sol::stack::call now calls functions flexibly, and getting is done more reliably
* due to the innovation of stack::call and using absolute indices, we no longer have to use reverse_call style programming to deal with lua
* sol::reference::get_type is now const-correct
* sol::state and sol::table now have a cleaned up `get` implementation since it is no longer held back by the ugliness of VC++'s incapability to handle templates
* the name `sol::userdata` now belongs to a type that actually encapsualtes a void* with a pusher/getter than gets a userdata void* value (TODO: give it a template to make it static_cast to that type on get?)
* lightuserdata_t -> light_userdata, upvalue_t -> upvalue as type names (mostly details)
* pushers for various types were updated to return integers
