How to name golang

In recent years, Golang has gradually become a popular language in the programming circle, and its "simple and efficient" ideas that it advocates are deeply loved by everyone. In the process of using Golang, naming is an important task. Good naming can improve the readability of the code and reduce the difficulty of later maintenance. So, how should naming be done in Golang? Next, this article will introduce the following aspects.

1. Naming rules

The naming rules in Golang are very simple, including the following points:

1. It consists of uppercase and lowercase letters, numbers, and underscores (_) .

2. The first character must be a letter or underscore.

3. You cannot use keywords in Go or predefined identifiers within the language as names.

4. The name should use camel case nomenclature, that is, the first letter of the word is lowercase, and the first letter of subsequent words is capitalized.

In practical applications, we must abide by the above naming rules when naming, so that our code can be standardized, easy to read and understand.

2. Package naming

In Golang, the package name should be short and concise, and can concisely summarize all the files contained in the package. Generally speaking, it is recommended that package names use lowercase letters, no underscores, and consist of one or more letters. Similar to the following:

package mypack

where mypack is the package name.

3. Variable name naming

In Golang, the variable name should describe the data it carries or its function. For example, name should be used to describe a person's name, path should be used to describe the path of a file, and so on. The naming of variable names should not be too simple or too complex, and should achieve a balance between readability and conciseness.

In addition, in Golang, there are some special types of variables, and their naming also has corresponding rules. For example:

1. Structure variable: The name of a structure variable should have the first letter capitalized, indicating that the variable is exposed to the outside world.

type Person struct{

Name string
Age int

}
var Person1 Person

2. Private variables: The names of private variables should be named in lowercase, indicating that the variable is only Visible within the current package.

var pvt string

4. Function name naming

In Golang, the naming of the function name should also describe its role or the function it implements. Generally speaking, we can include a description of its return type or parameter type in the function name to make it easier to understand.

func GetName() string{

return "Golang"

}

In addition, in Golang, the naming of function names also needs to follow the rules of capitalization of the first letter. For example, if the function name starts with a capital letter, it means that the function is exposed and can be introduced and used by other packages.

5. Naming constant names

In Golang, constants usually refer to variables that cannot be modified. The naming of constant names needs to be similar to variable names and should describe the meaning of the data or variables contained in the constant.

When naming, the letters of the constant name should be all capital letters, and use underscores as delimiters. For example:

const MAX_COUNT = 100

6. Conclusion

Good naming can provide better readability and maintainability for our code. In Golang, naming rules need to follow the principles of first letter case, camel case naming, conciseness and clarity. Only in this way can we write better and more reliable code and bring a better experience to our development and maintenance. I hope readers can understand and flexibly use these naming rules to write better code when learning Golang.
