What are the files in go language?

The files in the go language include source code files, package files, executable files, binary files, library files and Makefile, go.mod, go.sum, etc. 1. Source code file, containing program code used to implement functions; 2. Package file, which can be defined in one source code file or contain multiple source code files; 3. Execution file, used to run the program directly; 4. , Binary files, usually used to publish and deploy applications; 5. Library files, which can be referenced and called as dependencies of other programs.

Go language is an open source programming language used to build efficient and reliable software. In the Go language, files are the basic unit for organizing and managing code. In this article, we will introduce several common file types in the Go language.

1. Source Code file File): Source code file is a file containing Go language source code. Every source code file has a `.go` extension. Source code files contain the program code used to implement functionality. A project usually includes multiple source code files.

2. Package file File): Package files are a way to organize and manage related code. A package contains a set of related functions, variables, constants, etc. A package file can be defined in one source code file or contain multiple source code files. The extension of the package file is also `.go`.

3. Executable file File): The executable file is an executable file generated after compiling the source code file in the Go language and is used to directly run the program. In Windows operating systems, executable files usually have the extension `.exe`, but in Linux and Mac operating systems, they have no extension.

4. Binary file (Binary File): A binary file is a file generated after compilation and contains machine code. Binaries are commonly used to publish and deploy applications. In Go language, you can use `go The build` command compiles source code files into binary files.

5. Library file (Library File): Library files are files used to reuse code in program development. Library files contain a set of related functions and data structures that can be referenced and called as dependencies of other programs. In the Go language, the extension of library files is `.a`.

In addition to these common file types, there are some other auxiliary files used to support the development and build process of the project:

1. Makefile: Makefile is a file used for automated builds. By defining a series of rules and dependencies, code can be automatically compiled and deployed during development.

2. go.mod: go.mod is the description file of the Go language module, used to define and manage project dependencies. The go.mod file contains other modules and version information that the project depends on.

3. go.sum: go.sum is a supplementary file to go.mod, which is used to store the specific version and checksum of the module to ensure the code integrity and security of the project.

During the development process, it is very important to understand and use these file types correctly. Their reasonable organization and management can improve the readability, maintainability and reusability of the code, and help developers write and maintain Go language projects more efficiently. Whether it is source code files, executable files or library files, they are an important part of building a complete and runnable Go language application. .
