Question: How to be notified of package updates when using gopkg.in? about gopkg HOT 9 CLOSED

One approach would be a tool that tells you what packages are outdated. Whether using gopkg.in or not (Git SHA, tags/branches).

Well, I have two tools [1][2] that I use to find out when there are updates for normal Go packages (and update them via go get -u).

As is, they won't work to tell me if "gopkg.in/pipe.v3" happens to come out tomorrow, because that's a completely new Go package with a different import path that doesn't exist in my GOPATH, and "gopkg.in/pipe.v2" will be reported as "the latest version".

I could work my way around it and look for branches/tags in the GitHub repo... but before I start doing anything on my own, I want an official approach that is sanctioned by gopkg.in itself. That's why I'm asking this here.

What I was thinking is to fetch origin (not merge/pull) and look for refs in the same format as gopkg.in (v3).

A gopkg.in API would be a nice solution too, though it doesn't seem as generally applicable. (If I set up my own instance of gopkg.in on another domain, your app would need to know to query it).

@niemeyer Any comments on my original question?

I share the same concern as @nathany, whatever the approach I would like it to work with custom domains.

Just to be clear, the fact gopkg.in won't update automatically when go get -u is run is part of the main reason why it exists. If it updated automatically every time, then the software would be incompatible on major versions.

Regarding an API that tells whether a given revision is available:

$ curl -I gopkg.in/yaml.v3
HTTP/1.1 404 Not Found
Date: Mon, 01 Dec 2014 13:28:29 GMT
Content-Length: 98
Content-Type: text/plain; charset=utf-8

$ curl -I gopkg.in/yaml.v2
HTTP/1.1 200 OK
Content-Type: text/html
Date: Mon, 01 Dec 2014 13:28:31 GMT

Should be trivial to build a tool that reports whether X+1 is available based on the local package list.

@niemeyer Thanks, I appreciate the information. That makes sense and I can work with it.

It's not that I couldn't have figured it out on my own, but rather I wanted to be following an official specification rather than trying to come up with one on my own.

Just to be clear, the fact gopkg.in won't update automatically when go get -u is run is part of the main reason why it exists.

It will update to the latest version that falls within the same major version, but of course it won't jump to a higher major version on its own.

Given that you've answered my original question, this issue can be closed. But it would be helpful to make the API available somewhere more visible, like a section in README or on a wiki page.

I'll do that now. Thanks again!
