This will avoid compiler overhead for excessively large enumerations. If you use the second overload, you will create a (runtime) std::initializer_list. Use the dot syntax or syntax to insert by associative key. In other words, after doing table.insert, your button table will be at tmp1, tmp2 etc. The arguments are expected to come in key, value, key, value. table.insert works with the index part of the table only. If you plan on changing the enum values in Lua, set the read_only template parameter in your new_enum call to false. By default, the enum will be made read-only, which creates a tiny performance hit to make the values stored in this table behave exactly like a read-only enumeration in C++. Use this function to create an enumeration type in Lua. args ) template basic_table_core & new_enum ( const std :: string & name, std :: initializer_list > items ) Template basic_table_core & new_enum ( const std :: string & name, Args &. Please note how callables and lambdas are serialized, as there may be issues on GCC-based implementations. If there are further lookups past a key that do not exist, the additional lookups into the nil-returned variable will cause a panic to be fired by the lua C API. If the keys within nested queries try to traverse into a table that doesn’t exist, it will first pull out a nil value.
The second one ( traverse_set) sets a single value, using all but the last argument as keys to do another lookup into the value retrieved prior to it. It is similar to table = value_a table = value_b. The first one ( set) can set multiple values, in the form key_a, value_a, key_b, value_b. These functions set items into the table. args ) template table & traverse_set ( Args &. This function does not create tables where they do not exist. As a short-hand, easy method for returning a default if a value doesn’t exist, you can use get_or instead. If you need to check for keys, check with auto x = table.get>( std::tie("a", "b", "c" ) ), and then use the optional interface to check for errors. The second one ( traverse_get) pulls out a single value, using each successive key provided to do another lookup into the last. Because it returns a std::tuple, you can use std::tie/ std::make_tuple on a multi-get to retrieve all of the necessary variables.
It is similar to doing return table, table, table. In the case of multiple return values, it is returned in a std::tuple. The first one ( get) can pull out multiple values, 1 for each key value passed into the function. Lua is cross-platform, since the interpreter of compiled bytecode is written in ANSI C, and Lua has a relatively simple C API to embed it into applications. These functions retrieve items from the table. Lua (/ l u / LOO- from Portuguese: lua meaning moon) is a lightweight, high-level, multi-paradigm programming language designed primarily for embedded use in applications.
