Lua 是 8-bit clean 的: 字符串可以包含任何 8 位字符, 包括零结束符 ('\0') (参见 §2.1)。 Lua 可以调用(和处理)用 Lua 写的函数以及用 C 写的函数(参见 §2.5.8). userdata类型用来将任意 C 数据保存在 Lua 变量中。 这个类型相当于一块原生...

In Lua, indexing generally starts at index 1. But it is possible to create objects at index 0 and below 0 as well. Array using negative indices is shown below where we initialize the array using a for loop.main.luaOpen Compiler -- create an empty array array = {} -- initialize array...
Number表示实数(双精度浮点数)。 (编译一个其它内部数字类型的 Lua 解释器是件很容易的事;比如把内部数字类型改作 单精度浮点数或长整型。参见文件luaconf.h。)String表示一串字符的数组。 Lua 是 8-bit clean 的: 字符串可以包含任何 8 位字符, 包括零结束符 ('\0') (参见§2.1)。
Therefore, indexing starts from 1 as in Lua instead of 0 as in Python. For the same reason, negative indexing does not work. It is best to think of Lua tables as mappings rather than arrays, even for plain array tables. >>> table = lua.eval('{10,20,30,40}') >>> table[1] ...

(It is easy to build Lua interpreters that use other internal representations for numbers, such as single-precision float or long integers; see fileluaconf.h.)Stringrepresents arrays of characters. Lua is 8-bit clean: strings can contain any 8-bit chracter, including embedded zeros (’\0’)...
so it probably doesn't work properly. If you want to try 0 based indexing just set the variableTableIndexOffsetto 0. Note thatTableIndexOffsetis strictly a VM setting, the standard modules do not respect this setting (for example thetablemodule andipairswill still insist on using 1 as the...
