hslua-core-2.3.1 - Released 2023-03-17.
* New module HsLua.Core.Debug: the module provides bindings to a subset of
functions of the Lua debug interface. Currently the module only exports
getupvalue and setupvalue, both of which are also re-exported from
HsLua.Core.
hslua-core-2.3.0 - Released 2023-03-13.
* The functions loadfile, dofile, and dofileTrace now expect the argument
to be of type Maybe FilePath. The functions load from stdin when the
argument is Nothing.
* Added setwarnf' for simple warning messgae handling: The built-in method
of setting a warn function is flexible but not straight-forward to
use. The new setwarnf' function allows to set a Haskell action as a
warning hook: the default warning behavior is kept in place, but, in
addition to the default action, the hook is called on the concatenated
warning messages. This can be used to plug Lua warnings into an
application specific Haskell reporting system.
* Export GCManagedState, newGCManagedState, closeGCManagedState, and
withGCManagedState from HsLua.Core.
hslua-core-2.2.1 - Released 2022-06-19
* Ensure that loadfile works with umlauts in filepath: The OS does not
necessarily expect filenames to be UTF-8 encoded, especially Windows. On
non-Windows systems, the current file system encoding is now used to
convert filenames to C strings. On Windows, the CP_ACP codepage is used,
as required by the Windows API.
* GC managed Lua state: Add new type GCManagedState and functions
newGCManagedState, closeGCManagedState, and withGCManagedState. These
allow to create and use a Lua state in flexible ways in that it does not
require the state to be closed explicitly. The state will be closed when
the respective variable is collected.
* Require lua-2.2.1.
* Relax upper bound for mtl, allow mtl-2.3.
hslua-core-2.2.0 - Released 2022-02-19
* Use lua-2.2.0, which requires Lua 5.4.
* Rename newuserdata to newuserdatauv and let it take the number of
associated uservalues as an additional argument.
* Similarly, newhsuserdata is now newhsuserdatauv.
* Rename getuservalue and setuservalue to getiuservalue and setiuservalue,
respectively. Like both functions now take an extra argument specifying
the number of the uservalue that should be retrieved or set.
* It is now possible for setiuservalue to fail, so it returns a boolean to
indicate whether the action was successful.
* The GCControl type has been updated to match the new gc control:
- The GCStep constructor takes an argument "stepsize";
- constructors GCGen and GCInc have been added;
- constructors GCSetPause and GCSetStepMul have been removed.
