Domain-specific languages have become a hot topic; Many functional languages are popular, mainly because they can be used to build domain-specific languages. For this reason, in the 8th article in the Scala Guide series for Java™ developers, Ted Neward to build a simple calculator DSL to demonstrate the power of building an "external" DSL for functional languages. He examines a new feature of Scala: Case cl

Before we talked about the Elasticsearch (search engine) operation, such as: Add, delete, change, check and other operations are used Elasticsearch language commands, like SQL command, of course Elasticsearch Official also provides a python operation Elasticsearch (search engine) interface package, just like the SQLAlchemy Operation database ORM box, so that we operate elasticsearch do not have to write commands, Use the Elasticsearch-dsl-py module to

problem is the readability of the code. It is not easy to immediately see what this code wants to achieve, so it needs to be carefully checked for omission or not being strictly in line with the requirements. When requirements change, it is desirable to know exactly where the code needs to be modified and, as a modification, to be confident that it will not affect other functions. Meta-programming concepts are used to solve this problem.Pragmatic Programmer (pragmatic programmer?) The meta-prog

In this column last month, I covered an example of using a specific domain language (DSL), defined in your code as a common design practice. (I introduced the concept of idiomatic patterns in the "combining methods and SLAP" article.) DSL is a good medium for capturing patterns because they are declarative, easier to read than "normal" source code, and make your capture patterns stand out from the surroundi

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 implement its parser using the combined parser des

It's not something new, and the wireless router has been using it a long time ago, but it has only recently begun to understand its rationale. Now the network embedded device's function is more and more powerful, each chip manufacturer's solution method supports this kind of complexity.
