Go fmt

Commands are mainly used to help you format the written code files [many third-party integration software uses go fmt commands]

First, use:

Using the gofmt command is more likely to use gofmt, and parameters are required

-w, otherwise the formatting result will not be written to the file. Gofmt-w src, which can format the entire project.

2. Introduction of parameters

-l displays files that need to be formatted

-w writes the rewritten content directly to the file, rather than printing it to standard output as a result.

-r add rewriting rules such as "a [b: len (a)]-> a [b:]" to facilitate us to do batch replacement.

-s simplify the code in the file

-d displays the diff before and after formatting instead of writing to the file. The default is false

-e prints all syntax errors to standard output. If you do not use this flag, only the first 10 errors of different lines will be printed.
