Golang cancels automatic line wrapping

With the rapid development of Go language in recent years, many people have begun to learn and use Go language for development. However, during the use process, some people have encountered a more controversial issue: how to cancel the automatic setting of Go language. Line break. This issue has also caused some discussion in the community. Some people think that this is a feature of the Go language to keep the code standardized and readable, while some people think that this is a limitation that will affect their coding. experience.

In this article, we will explore this issue and provide some methods to cancel the automatic line wrapping function of Go language.

How to cancel automatic line wrapping in Go language:

Automatic line wrapping in Go language is implemented by the "gofmt" command in the standard library. This command formats the source code according to the specification and keeps the length of each line to no more than 80 characters. This means that if a line of code exceeds 80 characters, word wrapping will occur before spaces, commas, or periods to keep the code readable.

Although the existence of automatic line wrapping tools can make the code style more unified, in some cases, it can also cause us trouble, such as when we need to output a very long string or need to locate a certain When one line. In this case, canceling word wrapping can be very useful. The following are several methods to cancel automatic line wrapping in Go language:

1. Use the -vet command: The

-vet command is a grammar checking tool that comes with the Go language. It checks your code for errors and style irregularities and provides suggestions for fixes. In Go language, if you use -vet command with "go build" or "go test" command, it will check the code before compiling or testing. Therefore, if you want to cancel automatic line wrapping, please run the following command before compiling or testing:

$ go vet -x -vettool=$(which echo) ./...

This command will convert all Go files into a single line, thus canceling automatic wrapping.

2. Use Go Imports:

Go Imports is a Go language tool that can automatically add and delete the required packages for you based on the import path of the Go language package and the path of the current file. And format your code to Go language specifications. Therefore, if you want to cancel automatic line wrapping, first install Go Imports and run the tool with the following command:

$ goimports -w <filename>

This command will organize all Go language references in the 2334ac29606bf8a170583e4f7533b1f4 file into one line.

3. Use Go Format:

Go Format is the Go language’s own code formatting tool. If you only need to format the code to the Go language specification, please use the following command:

$ go fmt <filename>

This command will format the code according to the Go language specification and organize it into one line.

Summary:

Canceling the automatic line wrapping function of Go language is a controversial issue, especially for some developers who need to output long strings or need to locate a certain line. Although the automatic line wrapping tool can make the code style more unified, in some cases, it can also cause us trouble. In order to better meet the needs of developers, the Go language provides some methods to cancel automatic line wrapping. Depending on your actual needs, you can use tools such as -vet command, Go Imports or Go Format to achieve this purpose.
