Golang中是否存在任何命令行来检查我的go源代码的语法错误并将错误写入文件？

Question

package main

import "fmt"

func plus(a int, b int) int {
    return a + b
}
}
func plusPlus(a, b, c int) int {
    return a + b + c
}

func main() {
    res := plus(1, 2)
    fmt.Println("1+2 =", res)

    res = plusPlus(1, 2, 3)
    fmt.Println("1+2+3 =", res)
}

This is my Go Source code. gofmt -e my_file.go is working But I am not able to write the errors to a text file.

Answer 1

gofmt will output the errors to the standard error. You can simply redirect the standard error stream of gofmt to a file on unix systems like this:

gofmt -e my_file.go 2>a.txt

Checking it:

more a.txt

Output:

my_file.go:8:1: expected declaration, found '}'
