This change introduces a new visitation API to the new MuIL AST. The ast.Walk API takes an ast.Visitor implementation and walks the tree in depth-first order, invoking the visitor along the way. The visitor gets to choose whether to continue visitation (by returning a non-nil visitor object), or to stop it (by returning nil). The visitation will proceed with that returned visitor, so that a visitor can "swap out" the visitor used for child nodes if needed. At the end, the PostVisit function is called, for any clean up logic. Finally, the ast.Inspector type is available as a simple way of consing up visitors simply using a function that returns a bool indicating whether visitation should continue. |

Mu
Mu is a framework and toolset for creating reusable stacks of services.
If you are learning about Mu for the first time, please see the overview document.
Building and Testing
To build Mu, first clone it into a standard Go workspace:
$ mkdir -p $GOPATH/src/github.com/marapongo
$ git clone git@github.com:marapongo/mu $GOPATH/src/github.com/marapongo/mu
A good default value for GOPATH is ~/go.
Mu needs to know where to look for its runtime, library, etc. By default, it will look in /usr/local/mu, however you
can override this with the MUPATH variable. Normally it's easiest just to create a symlink:
$ ln -s $GOPATH/src/github.com/marapongo/mu /usr/local/mu
There is one additional build-time dependency, golint, which can be installed using:
$ go get -u github.com/golang/lint/golint
And placed on your path by:
$ export PATH=$PATH:$GOPATH/bin
At this point you should be able to build and run tests from the root directory:
$ cd $GOPATH/src/github.com/marapongo/mu
$ make
This installs the mu binary into $GOPATH/bin, which may now be run provided make exited successfully.
