PrefaceThe basic use method of boost.spirit.x3 is briefly described in the previous article. In four simple examples, we showed how to use the X3 organization to construct a grammar-generating formula that matches the source string and generates a synthetic attribute. In these simple examples, the complex syntax units, which are non-terminators, are created by combining the basic syntax units in the X3 library. But the syntax units in these examples d

About the principle of compiling this piece has not been involved before, this time to use the knowledge here will need to contact the content here. The principle of compiling, as its name implies, is the principle of dealing with high-level languages, which are called language (low-level languages) that computers can recognize. And what about grammar? Is the method used to describe the programming language. Similar to the Dharma, used to describe the

c++11 new Syntax 1:auto keywordOne of the most useful features that c++11 adds is the Auto keyword.I wonder if you've ever written such a code:STD::MAPstring, std::vector map;std:: Mapstring, std::vectorEven more complex templates are nested than this.In this case, not only is the code lengthy and error prone, but the compilation error message after the error is difficult to readThe use of auto can greatly simplify the writing of the code, but also reduce the possibility of spelling mistakesSTD:

The specific analysis is as follows: The structure grammar represents the new allocation of a struct by the value of the Structure field as a list.Use the Name: syntax to list only some of the fields.
