1 Introduction

The go language is a new programming language launched by Google that can reduce the complexity of your code without compromising application performance. Rob Pike, Google's Chief software engineer, said: "We've developed go because software development has been frustrating over the last more than 10 years." Go is the second Google 2009 release programming language. In July 2009, Google released the simple language, a basic language used to develop Android apps. Beijing time January 10, 2010, go language picked Tiobe released the 2009 annual award. The award was awarded to the programming language with the largest increase in market share in 2009. "Go gives me the experience I've never had before," said Rob Pike, Google's senior software engineer, Rob Paik. Parker says that today's C + + or C, go is a system language. "Using it for rapid development, and it's a true compilation language, we're now opening it up because we think it's very useful and powerful," he explains. "In 2007, Google started research and development on go as a 20% project, which allows employees to devote 20% of their jobs to the project. In addition to Parker, members of the project also have some other Google engineers. Parker says that after compiling the go code, the run speed is very close to the C language, and the compilation speed is very fast, as if using an interactive language. None of the existing programming languages have been specifically optimized for multicore processors. Go is a language that Google engineers write for such programs. It is not designed for beginners, but learning to use it is not very difficult. Go supports object-oriented, with features such as true encapsulation (closures) and reflection (reflection). In terms of learning curve, Parker thinks go is similar to Java, and it should be easy for Java developers to learn go. The reason to publish go as an open source project is to give the open source community the opportunity to create better tools to use the language, such as plugins in the Eclipse IDE. Go was not used in all of Google's publicly available Web applications, but Google has developed several in-house projects using the language. Parker said that whether go will have an impact on Google's upcoming Chrome OS, too early is too early, but go can indeed be used with native client. "Go allows apps to run perfectly in the browser," he says. "For example, using go can make wave more efficient, both in the front-end and in the background. Go also has two compilers, one based on GCC and one set of compilers (6g and 8g) for 64-bit x64 and 32-bit x86 computers, respectively. Gccgo. Google is currently developing its support for ARM chips and Android devices. Parker said, "AndroThe problem with ID phone is that we have never had a math coprocessor. ”

2 Target

The goal of GO is to improve the management of existing programming languages such as library dependencies (dependency), which are called repeatedly by applications. Because of the parallel programming pattern, this language is also designed to solve multiprocessor tasks. Google started developing go in about 2007 and invested in a full-time workforce in 2008. Google originally designed the language as a system programming language that could be used in Web servers, storage systems, and databases. But Google believes the language is also expected to be used in other areas.

3 Application

Because go is not yet mature, Google's app engine and other parts of the product have started to be written in the go language. That's why Google needs the help of external programmers. "We need better libraries and tools, and the open source community can help us a lot in these areas," Parker said. By creating a new programming language, Google will continue to expand all aspects of computing in order to promote development in these areas. It is also the motivation for Google to develop its Android operating system, Chrome browser and Chrome OS.

4 function

Google has great expectations for go. It is designed to give full play to the advantages of multi-core processor synchronization and multi-work, and to solve the problem of object-oriented programming. It has modern programming language features, such as garbage collection, to help programmers handle trivial but important memory management issues. Go is also very fast, almost as fast as C or C + + programs, and can be quickly produced. Go's website is built with go, but Google has bigger ambitions. The software is 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, instead of the role of JavaScript. "It's at least a level higher in intensity than JavaScript," says Pike. Google has built its own Chrome browser, partly to speed up JavaScript and Web performance, and Google has fused its own technology, such as native Client and gears. Pike said that another network-related feature of Go is that servers and user-side devices, such as PCs or mobile phones, can share work. As a result, the Go service makes it easy to adapt to different user-side processing performance. Go also solves one of today's biggest challenges: multi-core processors. General computer programs are usually executed sequentially, one at a time, but multi-core processors are more suitable for multitasking. "We think we have enough support to improve the problem," Pike said. The Go team is looking for help. One important area is to improve the runtime library that go can use. This kind of library can provide many tools and functions to speed up the process of programming. The Go Library also includes many important design elements and supplies resources to handle the same work, garbage collection and other low-level chores. The go team also needs compiler assistance. Thompson has written some compilers for the 32-bit and 64-bit x86 processors, and ARM processors, and Taylor has written a go frontend for the GCC compiler. Despite Google's ambitions for go, the company understands that the plan is not a complete replacement for existing technology. "I don't think we can replace anything," Pike said. We're just creating another role in this field.

Thompson also invented the B programming language, which later derived from the C language. Pike: Was a UNIX team at Bell Labs, and a member of the Plan 9 operating system program. He has worked with Thompson for many years and has been creating a widely used UTF-8 character encoding. Robert Griesemer: The hotspot compiler that helped make Java, and the Chrome browser's JavaScript engine V8. In addition, Plan 9 developer Russ Cox, Tseng improves the widely used Kaiyuan code compiler for GCC's Ian Taylor.

7 Brief History

In 2007, Google engineer Rob Pike, Ken Thompson and Robert Griesemer began to design a new language, the original prototype of the Go language.
