Go use of exec.Command on windows for noverify

问题:

I want to use VKCOM/noverify to analyse code. Calling it from the command-line (windows dos shell) using this command works

 noverify.exe -exclude-checks arraySyntax,phpdocLint 
              -output result.txt 
              C:\Dev\PHP\ResourceSpace_9_0_13357\include

The trouble is that i am unable to pass arguments to cmnd := exec.Command("noverify.exe", args)

options := " -exclude-checks arraySyntax, PHPDoc"
pathToCode := "C:\\Dev\\PHP\\ResourceSpace_9_0_13357\\include"

// this works
cmnd := exec.Command("noverify.exe", pathToCode)


args := []string{options, pathToCode}
arg := strings.Join(args, "")
// passing options does not work
// cmnd := exec.Command("noverify.exe", arg)    

b, err := cmnd.CombinedOutput()

What have i tried

You can find my source code in this gist It seems that args are joined as a string seperated by , despite that the separator is empty above.

Questions

1. How to pass multiple arguments to exec.Comman("yourFoo.exe", cmdArgs...)
2. Why is my attempt not working on windows?

回答1:

There are multible options to pass arguments to exec.Command:

You can use multible strings as arguments:

cmd := exec.Command("your-command", "arg1", "arg2")

If you have a slice of arguments, you can use the spread operator

args := []string{"-exclude-checks", "arraySyntax,phpdocLint", "-output", "result.txt", "your-path"}
cmd := exec.Command("your-command", args...)

To question two: In your code

options := " -exclude-checks arraySyntax, PHPDoc"
pathToCode := "C:\\Dev\\PHP\\ResourceSpace_9_0_13357\\include"

args := []string{options, pathToCode}

you're passing two options to the external program. If you wrote the same on the command line, you pass

your-command.exe " -exclude-checks arraySyntax, PHPDoc" "your-path"

This doesn't work, and is also the reason your program doesn't work.

In short, whereever you put a space between in a command, you need to have a separate argument to exec.Command. The example also does this.
