gopack

The natural logarithm to Go's e. Simple package management for Go a la rebar.

A configuration file named gopack.config tells gopack about your dependencies and which version should be included. You can point to a tag, a branch, or, if you are being naughty, master. The programming community would thank you not to carry out such a travesty as it leaves your code open to breaking changes. Much better to point at immutable code.

gopack.config

[deps.memcache]
import = "github.com/bradfitz/gomemcache/memcache"
tag = "1.2"

[deps.mux]
import = "github.com/gorilla/mux"
branch = "1.0rc2"

[deps.toml]
import = "github.com/pelletier/go-toml"
commit = "23d36c08ab90f4957ae8e7d781907c368f5454dd"

Inside the configuration file you can also specify your project's repository name and it will be linked before pulling dependencies. For instance, let's say you have a reference to a subdirectory from your own project like this:

import "github.com/login/repo/dir"

You can declare it's repository name and it won't be pulled from the remote repo:

repo = "github.com/login/repo"

# Put other dependencies here.

Then simply run, install, and test your code much as you would have with the go command. Just replace go with gp.

gp test gp run *.go

etc…

The gp command will make sure your dependencies are downloaded, their respective git repos are pointed at the appropriate tag or branch, and your code is compiled against the desired library versions. Project dependencies are stored locally in the vendor directory.

Installation

First checkout and build from source

git clone git@github.com:d2fn/gopack.git
cd gopack
go get github.com/pelletier/go-toml && go build -o gp

Then copy the gopack binary to your project directory and invoke just as you would go. Make sure the current directory is on your path or place the gp binary elsewhere on your path.

cp gp ~/projects/mygoproject
cd ~/projects/myproject
gp run *.go

Sources and Scms

Gopack uses goget to download packages by default, but when you need more control over downloads you can be more specific about the source and the type of scm.

For example, if you want to download the source using git via ssh, you can provide the ssh url and specify git as a scm:

[deps.mux]
import = "github.com/gorilla/mux"
source = "git@github.com:gorilla/mux.git"
scm = "git"

You can do the same with Mercurial, hg, and Subversion, svn.

Gopack commands

Gopack includes a few tools to help you track your project dependencies.

1. ./gp dependencytree shows the complete list of external dependencies in your project.
2. ./gp stats shows statistics about dependency imports.
3. ./gp installdeps installs the project dependencies using go install ....
