By default, encoding the following Lua values will generate errors: Numbers incompatible with the JSON specification (infinity, NaN) Tables nested more than 1000 levels deep Excessively sparse Lua arrays 我们可以通
Nil values Luasnilconverts tonullptror 0 for pointer types, can be checked for withisNilref()and is different than the integer0. When you want to passnilto lua either passnullptr/(void*)0orkaguya::NilValue. state["value"] = kaguya::NilValue();//or state["value"] = nullptr;//or ...
This allows you to have simple, expressive APIs that access context that is unavailable to the Lua code. Encoding and Decoding data When working withLua, you may want inject data of various types into the runtime. Some values, such as integers, have the same representation inside of the run...
For instance, consider a C function that swaps two values: voidswap (double* x,double* y); or voidswap (double& x,double& y); If such a functionisdeclaredinthe package file, tolua binds itasa function receiving two numbersasinput and returning two numbers. So, a valid Lua code would ...
which is a container for Lua values such as Lua strings or tables. You can think of the Lua stack as a window into the set of Lua values currently relevant to your C code. We’ll dive into all the relevant details of this stack and the interlanguage interface within the first three ch...
Add navigation to window ( ctrl+3 or Ctrl+P ),including search files, quickly search function and variable; Stability improvement: some other bug fix; V1.6.8.0 - 2014.9.5 New feature: watch string variable values during debugging, support multiple languages: English, Simplified Chinese, Tradition...

rangecan be used to slice out raw values, eg.foo = "bar"will return aStringLiteraltoken with the valuebar. Slicing out the range on the other hand will return"bar". varparser = luaparse.parse('foo = "bar"', {wait:true}); parser.lex();// { type: 8, value: "foo", line: 1...
A non-nil Redis "multi-bulk reply" results in a Lua table holding all the composing values (if any). If any of the composing value is a valid redis error value, then it will be a two element table{false, err}. A nil multi-bulk reply returns in angx.nullvalue. ...
is used to convert function arguments from the target language to C There is a bunch of pre-defined fields that you can use in a typemap, which are expanded with function-specific values during code generation, e.g. $1will be replaced by the name of the variable used by SWIG as argume...
