将参数传递给GoLang中的filepath.Glob函数

Question

I've been trying to get my head around with GoLang for few days and I am trying to make simple program which matches to certain files in certain directory. However I don't know how to pass variable to filepath.Glob function.

My attempt:

func ReadDirectory(srcDir string) {
    files, _ := filepath.Glob("[a-Z0-9]")
    fmt.Println(files)
}

This one prints well current directory where I am running the program. However I am looking for a way to list pass srcDir variable to it so I can find files from whatever directory.

Answer 1

Just prefix the pattern with the directory:

files, _ := filepath.Glob(srcDir + "/[a-Z0-9]")

The docs give this example:

The pattern may describe hierarchical names such as /usr/*/bin/ed (assuming the Separator is /).
