lua uses PVP Versioning.

lua-2.1.0

Released 29-01-2022.

• The functions lua_rawget and lua_rawgeti now return the type of the value that was pushed to the stack.

• Added bindings to unsafe function lua_arith. A new type ArithOPCode for arithmetic operations is added, as are pattern synonyms for the supported operations. These are:

  • LUA_OPADD
  • LUA_OPSUB
  • LUA_OPMUL
  • LUA_OPDIV
  • LUA_OPIDIV
  • LUA_OPMOD
  • LUA_OPPOW
  • LUA_OPUNM
  • LUA_OPBNOT
  • LUA_OPBAND
  • LUA_OPBOR
  • LUA_OPBXOR
  • LUA_OPSHL
  • LUA_OPSHR

• Added ersatz functions hslua_arith and hsluaL_requiref, wrapping lua_artih and luaL_requiref, respectively. Both functions catch any error resulting from the call.

• Made types OPCode, StatusCode, and GCCode instances of type class Show.

• The Show instances of Integer and Number now behave like those of the wrapped types. Both types are now also instance of Read.

• Removed hslua_userdata_gc from hslua.h.
