Intro

Using gx as a go vendoring tool and package manager is (or at least, should be) a very simple process.

Creating a new package

In the directory of your go package, just run:

gx init --lang=go

And gx will create a new package.json for you with some basic information filled out. From there, all you have to do is run gx publish (ensure you have a running ipfs daemon) and gx will give you a package hash. That works fine for the base case, but to work even more nicely with go, we recommend setting the import path of your package in your package.json, like so:

package.json

{
    ...
    "gx":{
        "dvcsimport":"github.com/whyrusleeping/gx-go"
    }
}

Importing an existing package

Importing an existing go package from gx is easy, just grab its hash from somewhere, and run:

gx import <thathash>

If the package you are importing has its dvcs import path set as shown above, gx will ask if you want to rewrite your import paths with the new gx path. If you say no to this (as is the default), you can rewrite the paths at any time by running gx-go rewrite.

Some notes on publishing

It is recommended that when you publish, your import paths are not rewritten. The gx-go post install hook will fix that after the install, but for 'same package' imports, it works best to have gx rewrite things after the fact (Its also sometimes nicer for development). You can change paths back from their gx paths with:

gx-go rewrite --undo

NOTE:

It is highly recommended that you set your GOPATH to a temporary directory when running import. This ensures that your current go packages are not affected, and also that fresh versions of the packages in question are pulled down.
