Kang of Regil VII

What is this?

Many folks are frustated with the $GOPATH single workspace model, it doesn't let them check out the source of a project in a directory of their choice and it does not let them have multiple copies of a project checked out at the same time. Similarly many folks are frustrated with the gb project model, which gives you the ability to check out a project anywhere you want, but has no solution for libraries, and gb projects are not go gettable.

kang is an experiment to try to provide a solution that:

  1. lets you checkout a project anywhere you want
  2. does not force you to give up interoperability with go get.

Kodos uses .git

The reason $GOPATH is required by the go tool is twofold

  1. all import statements are resolved by the go tool relative to a fixed absolute root; $GOPATH/src.
  2. a location to store dependencies fetched by go get.

gb showed that point 2 could be solved by writing a new build tool that did not wrap the go tool and thus was not forced to reorganise the world to fit into the $GOPATH model.

The problem with point 1 is whenever the go tool builds a package in a directory, it must answer the question of "what is the full import path of this package". The $GOPATH model answers this question by subtracting the prefix of $GOPATH/src from the path to the directory of the current package; the remainder is the package's fully qualified import path. This is why if you checkout a package outside a $GOPATH workspace, the go tool cannot figure out the packages' fully qualified import path and everything falls apart.


kodos requires Go 1.7.3 or later.

go get


note: not done, see roadmap and TODO.

kodos build will build all the source in a project, it can be issued anywhere in the project. kodos test will test all the packages in a project, ditto.

Both commands automatically cache as much as possible for fast incremental compilation.


Here are the big ticket items before kang is a working proof of concept.

  • kodos test support.
  • automatic dependency fetching.
  • cgo support.
  • cross compile support.


Lots to do.

  • unit tests
  • functional and integration tests
  • kang has forked a number of gb components, merge the changes required back into gb so both kang and gb use the same build and test primatives.
