gb is a proof of concept replacement build tool for the Go programming language.

I gave a talk about gb and the rational for its creation at GDG Berlin in April 2015, video and slides.

gb operates on the concept of a project. A gb project is a workspace for all the Go code that is required to build your project.

A gb project is a folder on disk that contains a subdirectory named src/. That's it, no environment variables to set. For the rest of this document we'll refer to your gb project as $PROJECT.

You can create as many projects as you like and move between them simply by changing directories.

go get github.com/constabulary/gb/...

gb has its own site, getgb.io, head over there for more information.

In rough order

• Cross Compilation
• gb test improvements, test output, flag handling
• gb vendor updates and bug fixes
• new package resolver (replace go/build)

Big ticket items that are not on the road map yet

• Race detector support
• Tag handling, unify -tags, ENVVARS and GOOS/GOARCH into a single format for binary names and pkg cache
• Package BuildID support (make stale detection work like the Go 1.5)
• gccgo toolchain support.

We welcome pull requests, bug fixes and issue reports.
