With the popularity and usage of Golang in the development field in recent years, people have gradually formed their own understanding and experience of Golang's usage. So, what is the idiom in Golang? Next, let’s explore it.

  1. Follow Go’s code style

Golang’s code style is relatively strict and standardized. It uses tab indentation instead of space indentation, and the end of the line is not A semicolon is required and the code must be encoded in UTF-8. At the same time, the code should follow the principle of one function per function, and function names should be named starting with a verb as much as possible.

  1. Use short package names

In Golang, the package name is an important concept that is imported and used using import. To be as concise and clear as possible, package names should be as short as possible, but still meaningful.

For example, one of the more common package names is "http", which is used to provide HTTP-related functions and types, as well as perform operations such as HTTP requests and responses.

  1. Use the defer keyword

The defer keyword is a very useful tool when writing Go language programs. It ensures that resources are released when the current function ends, which not only avoids memory leak problems, but also effectively reduces the complexity of the code. defer can be placed anywhere, but it should be noted that the calling order of defer functions is first in, last out, that is, first in, last out.

  1. Use interface instead of concrete type

In Golang, interface is a very powerful and flexible concept. Using interface instead of concrete types can improve the flexibility of the code and make the program easier to expand and maintain. In most cases, it is better to use interfaces to write code, which can make the code more flexible and extensible.

  1. Use go vet for static analysis

Golang provides a static analysis tool called go vet, which can help users find some common errors and Problems with code irregularities. Using go vet allows programmers to point out errors in the code in time during the coding process, thereby avoiding low-level errors in the code.

  1. Using Go Modules

For Golang programmers, Go Modules is a very important package management method. Go Modules can automatically download and manage dependency packages, and can also provide a lot of help during code maintenance and upgrades. Go Modules can be used as command line tools or integrated into development tools.

  1. Avoid excessive use of synchronization locks

In concurrent programming, synchronization locks are an inevitable concept. However, you should be aware when using it that excessive use of synchronization locks will reduce the performance of the program, because synchronization locks consume a lot of CPU resources. Therefore, when writing concurrent programs, excessive use of synchronization locks should be avoided as much as possible.

  1. Handle errors immediately

In Golang, it is a very good idiom to enforce immediate error handling. Only in this way can errors be avoided from being ignored and causing problems when running the code. Therefore, when writing code, be sure to handle all possible errors in a timely manner.

Summary

There are many idioms in Golang. These idioms can help programmers write high-quality code that is highly readable, easy to maintain and expand. Through the above introduction to Golang idioms, we can see that these idioms are widely used in actual coding and are important principles that Golang programmers must master and follow.

The above is the detailed content of golang idioms. For more information, please follow other related articles on the PHP Chinese website!

C   and Golang: When Performance is CrucialC and Golang: When Performance is CrucialApr 13, 2025 am 12:11 AM

C is more suitable for scenarios where direct control of hardware resources and high performance optimization is required, while Golang is more suitable for scenarios where rapid development and high concurrency processing are required. 1.C's advantage lies in its close to hardware characteristics and high optimization capabilities, which are suitable for high-performance needs such as game development. 2.Golang's advantage lies in its concise syntax and natural concurrency support, which is suitable for high concurrency service development.

Golang in Action: Real-World Examples and ApplicationsGolang in Action: Real-World Examples and ApplicationsApr 12, 2025 am 12:11 AM

Golang excels in practical applications and is known for its simplicity, efficiency and concurrency. 1) Concurrent programming is implemented through Goroutines and Channels, 2) Flexible code is written using interfaces and polymorphisms, 3) Simplify network programming with net/http packages, 4) Build efficient concurrent crawlers, 5) Debugging and optimizing through tools and best practices.

Golang: The Go Programming Language ExplainedGolang: The Go Programming Language ExplainedApr 10, 2025 am 11:18 AM

The core features of Go include garbage collection, static linking and concurrency support. 1. The concurrency model of Go language realizes efficient concurrent programming through goroutine and channel. 2. Interfaces and polymorphisms are implemented through interface methods, so that different types can be processed in a unified manner. 3. The basic usage demonstrates the efficiency of function definition and call. 4. In advanced usage, slices provide powerful functions of dynamic resizing. 5. Common errors such as race conditions can be detected and resolved through getest-race. 6. Performance optimization Reuse objects through sync.Pool to reduce garbage collection pressure.
