Fetching packages in golang can be difficult, especially when juggling multiple packages, and private repositories. GIGO (Gigo Installer for Go) tries to solve that problem, effectively being the golang equivalent of python's pip.
The direct result of using gigo, is that a requirements.txt file can now be used for golang projects, making it easy to componentize golang projects. Through using gigo, components can now have their own life cycles, and be managed, even within private repositories.
How Gigo Works
For all packages that can be fetched using the existing go get calls, Gigo acts as a wrapper. For elements in private repositories, gigo calls out to the appropriate revision control tool, like git.
Packages can be installed in several ways. You can use a go getable path, a go getable path and a commit number for versioned code, or the path, optional version, and a URL to pull the code from. If a url is used, gigo will copy the repository found at that url into the path specified.
Make sure you've set your GOPATH and then:
gigo install github.com/BurntSushi/toml gigo install github.com/BurntSushi/toml github.com/kr/fs gigo install -r requirements.txt gigo uninstall github.com/BurntSushi/toml gigo --help
First, make sure your GOPATH has been set. On unixes, simply run sh build.sh. On Windows, run build.bat.
Outputs are stored in dist/gigo and dist/gigo.exe respectively. At that point, you'll want to copy the binary produced, into a known location.
Requirements File Format
The gigo requirements.txt file follows python's pip as inspiration. Each line in the requirements file should represent a gigo fetchable item. In the case of private github repositories, you can specify a hash or tag, as well as a destination.
Hashes or tags can be specified following a hashmark. Similarly, a destination is specified by adding a comma. Below is an example of a valid requirements.txt file, using some random repositories.
github.com/BurntSushi/toml firstname.lastname@example.org:kr/fs#2788f0 email@example.com:liamstask/goose#8488cc4, bitbucket.org/liamstask/goose
Ideally, rcsget.go would be extended, to add support for mercurial, subversion, and pretty much anything else under the sun. We'd also like to make it easy to upgrade packages.
