Introduction: Ward Cunningham once said that clean code clearly expresses what the code writer wants to express, while graceful code goes further, and beautiful code looks like it is specifically for the problem to be solved. In this article, we will show the design and implementation of a modular parser, the final code is graceful and extensible, as if it were to parse a particular syntax. We will also select an example in the H.248 protocol to imple

The last blog talked about the problem of constructing a syntax tree. A friend asked me in a message, why do I have to let the parser produce a syntax tree, rather than let the user decide what to do? I'm here to answer this question first. 1, most of the cases are really need to have a syntax tree 2, if you want to return directly to the results of such things, just write a visitor run the syntax tree is good, except for automatically generated code

In the previous article, the use of the SAX parser to parse an XML file, the advantage of a SAX parser is that it consumes less memory. This article focuses on parsing XML files using the DOM parser. The advantages of DOM parsers may be intuitive to understand, and of course everyone may have different preferences for different analytic methods. But Dom

In actual project development, if you need to parse the mathematical formula and do not need to use the interpreter mode for design, you can directly use some third-party parsing toolkit, which can be collectively referred toMath expression parser (MEP), Such as expression4j, Jep, jbcparser, symja, mathExpression string Parser (MESP) and so on replace the interpreter mode, which can easily explain some more

Scala: Operator and parser, scala operator ParsingThe names of variables, functions, and classes are collectively referred to as identifiers. The backquotes can contain almost any character sequence.In scala,-Operator ending with Colon-Value assignment operatorAll operators are left-bound. The unapply method accepts an object and then takes the value from it, usually the value originally used to construct the object. The sequence of values of any len

Sometimes, we need to generate an XML file. There are many ways to generate an XML file. For example, we can use only one stringbuilder to group XML content and then write the content into the file; you can also use the pull parser to generate xml files by using Dom APIs. We recommend that you use the pull parser. Use the pull parser to generate a myitcast. xml f

The dash parser is highly efficient, but not as powerful as bash, so there are errors that cannot be found when parsing some commands. To modify the default script parser for bash, the method is as follows: 1, command line input: sudo dpkg-reconfigure dash
