Function LuaPPrint

engine/script/src/script.cpp:618–652

pretty printing * Pretty printing of Lua values. This function prints Lua values * in a manner similar to +print()+, but will also recurse into tables * and pretty print them. There is a limit to how deep the function * will recurse. * * @name pprint * @param v [type:any] value to print * @examples * * Pretty printing a Lua table with a nested tabl
