Size overhead of urfave/cli

[abitrolly]

Just wondering that is the size overhead of urfave/cli?

Inspired by this post https://www.dolthub.com/blog/2022-11-07-pruning-test-dependencies-from-golang-binaries/

Minimal hello in Go is 1.73Mb.

$ go build hello.go
$ ls -la
total 1780
drwxr-xr-x. 2 anatoli anatoli      80 Nov 23 16:08 .
drwxr-xr-x. 4 anatoli anatoli      80 Nov 23 16:06 ..

-rw-r--r--. 1 anatoli anatoli      66 Nov 23 16:04 hello.go
$ cat hello.go 
package main

import "fmt"

func main() {
	fmt.Println("hello")
}

Minimal urfave/cli is 4.21Mb.

$ go build                                                                                                                                                   /0,1s

Using urfave_cli_no_docs flag cuts the binary size down a little.

$ ls -l hello
