Question content

I can already use Go Build to delete the current directory information of the project, and I can also delete the Gopath information, as shown below. Now I can only delete one of them individually

go build -gcflags“all=-trimpath=${GOPATH}” -asmflags“all=-trimpath=${GOPATH}”

But I don't know how to delete them simultaneously, I don't know how to combine it

On Windows I try this

go build -gcflags“all=-trimpath=�%” -asmflags“all=-trimpath=�%” -gcflags“all=-trimpath=%GOPATH%” -asmflags“all=-trimpath= %"GOPATH%"

Not working

Final Results

@ZekeLu, the answer is correct.

I want to explain what happened, I originally wanted to remove the GOROOT information, but I wrote GOPATH, so I thought @ZekeLu's second answer was wrong, now I modified it and tested it, no problem, both The answers are all correct p>

Solution

Try this command:

go build -trimpath

This is the documentation for the -trimpath flag of the go command:

-Trim path

Remove all file system paths from the generated executable. Logged filename instead of absolute filesystem path will start module path@version (when using modules), Or a normal import path (when using the standard library or gopath).

If you just want to remove some prefixes, you can do this:

go build -gcflags "all=-trimpath=%cd%;%gopath%" -asmflags "all=-trimpath=%cd%;%gopath%"

Compile commands and asm commands call objabi.applyrewrites to prune paths. According to objabi's implementation of .applyrewrites, the rewrites argument is a ;-separated list of rewrites.

// ApplyRewrites returns the filename for file in the given directory,
// as rewritten by the rewrites argument.
//
// The rewrites argument is a ;-separated list of rewrites.
// Each rewrite is of the form "prefix" or "prefix=>replace",
// where prefix must match a leading sequence of path elements
// and is either removed entirely or replaced by the replacement.
func ApplyRewrites(file, rewrites string) (string, bool) {
    start := 0
    for i := 0; i <= len(rewrites); i++ {
        if i == len(rewrites) || rewrites[i] == ';' {
            if new, ok := applyRewrite(file, rewrites[start:i]); ok {
                return new, true
            }
            start = i + 1
        }
    }

    return file, false
}
