Overview

This gist is based on the information available at golang/dep, only slightly more terse and annotated with a few notes and links primarily for my own personal benefit. It's public in case this information is helpful to anyone else as well.

I initially advocated Glide for my team and then, more recently, vndr. I've also taken the approach of exerting direct control over what goes into vendor/ in my Dockerfiles, and also work from isolated GOPATH environments on my system per project to ensure that dependencies are explicitly found under vendor/.

At the end of the day, vendoring (and committing vendor/) is about being in control of your dependencies and being able to achieve reproducible builds. While you can achieve this manually, things that are nice to have in a vendoring tool include:

	#include <sys/socket.h>
	#include <netinet/in.h>
	// #include <linux/if_ether.h>
	#include <stdio.h>
	#include <stdlib.h>

	#define IPPROTO_OSPFIGP 89

	void error(int ret, const char *err) {
	printf("%s: ret=%d\n", err, ret);

	#!/bin/bash

	total_ram_bytes=0
	total_disk_bytes=0

	format="%12s \| %12s \| %20s\n"

	printf "%16s \| %12s \| %12s\n" "index" "ram_bytes" "disk_bytes"
	echo "---------------------------------------------------------"
