Go language is a system language. Go language is a system-level language. It is designed to solve practical problems in the development process of large-scale systems. It supports concurrency, standardized unified, simple and elegant, and powerful performance. Its main goal is to "have the development speed of dynamic languages ​​​​such as Python." and Performance and Security of Compiled Languages ​​such as C/C”. The Go language is specially optimized for programming multi-processor system applications. Programs compiled using Go can be as fast as C or C code, are more secure, and support parallel processes.

The operating environment of this tutorial: Windows 7 system, GO version 1.18, Dell G3 computer.

What is system programming? Why is Golang a systems programming language?

System programming is writing software to extend or enhance the functions of the operating system.

A good example of a system program is the mouse and keyboard drivers, and the file management system that comes with the operating system.

Even the entire windows or Mac system.

Apps downloaded on computers and mobile phones, and temporary blog pages are not classified as system programming.

When Google developed the Go language, there were some problems it hoped to solve:

  • Compilation time without sacrificing too much performance.

  • Fast execution time relative to interpreted languages.

  • Static binary, no need to worry about system dependencies or special runtimes.

  • The concurrency model that works is easier, easier to do things the right way.

All these attributes make Golang a good candidate as a systems programming language.

Is go language a system language?

Go language is the second open source programming language released by Google in 2009. It is a system-level language. It is designed to solve practical problems in the development process of large-scale systems. It supports concurrency, unified specifications, simplicity and elegance, and powerful performance; its main goal is to "have both the development speed of dynamic languages ​​such as Python and the speed of compiled languages ​​such as C/C." Performance and Security”.

The Go language is specially optimized for programming multi-processor system applications. Programs compiled using Go can be as fast as C or C code, are more secure, and support parallel processes.

Background introduction

The Go language is a new programming language launched by Google that can reduce the complexity of the code without losing application performance. Rob Pike, chief software engineer at Google, said: We developed Go because software development has been frustratingly difficult over the past decade or so.

On January 10, 2010, Beijing time, the Go language won the 2009 Annual Award announced by TIOBE. This award is given to the programming language with the largest market share growth in 2009.

Rob Pike, a senior software engineer at Google, said, "Go allows me to experience development efficiency that I have never experienced before." Pike said that, like today's C or C, Go is a system language. He explained, "You can use it for rapid development, and it is also a real compiled language. The reason why we open source it now is because we think it has been very useful and powerful."

In 2007, Google started developing Go as a 20% project, allowing employees to devote 20% of their time outside of their own work to investing in the project. In addition to Parker, other Google engineers are also members of the project.

Pike said that the running speed of compiled Go code is very close to that of C language, and the compilation speed is very fast, just like using an interactive language. None of the existing programming languages ​​are specifically optimized for multi-core processors. Go is a language written by Google engineers for this type of program. It's not designed for beginners in programming, but learning to use it isn't very difficult either. Go supports object-oriented and has features such as true closures and reflection.

In terms of learning curve, Parker believes that Go is similar to Java, and Java developers should be able to learn Go easily. The reason why Go is released as an open source project is to give the open source community the opportunity to create better tools for working with the language, such as plug-ins in the Eclipse IDE.

Go is not used in any of Google's publicly released web applications, but Google has developed several internal projects using the language. Parker said it's too early to say whether Go will have an impact on Google's upcoming Chrome OS, but Go can indeed be used with Native Client. He said that "Go allows applications to run perfectly in the browser." For example, using Go can implement Wave more efficiently, both in the front end and the backend.

Go has two compilers at the same time, one is Gccgo based on GCC, and the other is a set of compilers (6g and 8g) for 64-bit x64 and 32-bit x86 computers respectively. Google is currently developing its support for ARM chips and Android devices. Parker said, "The problem with Android phones is that we have never had a math coprocessor."

Goal

The goal of Go is to improve the management of dependencies such as libraries by existing programming languages. These software elements will be called repeatedly by applications. This language is also designed to solve multi-processor tasks due to the existence of parallel programming models.

Google started developing Go around 2007 and invested a team of full-time employees in 2008. Google originally designed the language as a systems programming language that can be used in network servers, storage systems and databases. But Google believes that the language has potential to be used in other areas.

Features

Google has high hopes for Go. Its design is to allow the software to take full advantage of the simultaneous multitasking of multi-core processors and to solve the troubles of object-oriented programming. It has modern programming language features, such as garbage collection, to help programmers deal with trivial but important memory management issues. Go is also very fast, almost as fast as C or C programs, and can quickly create programs.

Go's website was built using Go, but Google has greater ambitions. The software is specifically designed for building server software (such as Google's Gmail). Google believes that Go can also be applied to other areas, including executing software in the browser and replacing the role of JavaScript.

Go also solves one of today's big challenges: multi-core processors. Normal computer programs usually execute sequentially, one job at a time, but multi-core processors are better suited to processing many jobs in parallel. Pike said: We believe we have enough support to improve this aspect.

Although Google has big ambitions for Go, the company also understands that this plan cannot completely replace existing technology. Pike said: I don't think we can replace anything. We just create another character in this realm.
