There are two rocket boosters on both sides of the U.S. space Shuttle fuel tank, as these boosters are built to be transported by train and some tunnels are going to be wider than the train rails, so the width of the rocket booster is determined by the width of the rai

The most fashionable use of C + + now is template meta programming. Booster are very fond of this, I am also a fanatical booster. To what extent. Do not use template is not comfortable, do not boost a bit feel sorry for C + +. But the serious consequence of this mania is that the program compiles at a very slow rate, and the resulting execution program is unusually large.
Once a C + + server program, the co

Recently, we found that users may be asked to build their own Query expressions in the project. For example, you need to enter a set of Query expressions with logical relationships through a configurable interface, and then filter and return the required data based on the query expression. This type of User case is actually very common. Inspired by this, we may be able to define a general query-oriented domain-specific language (DSL) for serialization

Why use gradle?
Gradle is a relatively advanced building system and a good building tool that allows you to customize building logic through plug-ins
The following are the main reasons why Android studio chooses gradle:
Use domain specific language to describe and process the building logic. (DSL)
Based on groovy. DSL can mix various declarative elements and use code to manipulate these

I have imagined such a software system: its core functions are completely exposed to the outside by a DSL, and all business operations are carried out through this DSL, business rules in this field can be configured through a rule engine, so this
