Go Report Card

A web application that generates a report on the quality of an open source go project. It uses several measures, including gofmt, go vet, go lint and gocyclo. To get a report on your own project, try using the hosted version of this code running at goreportcard.com.

Installation

Assuming you already have a recent version of Go installed, pull down the code with go get:

go get github.com/gojp/goreportcard

Go into the source directory and pull down the project dependencies:

cd $GOPATH/src/github.com/gojp/goreportcard
make install

Now run

make start-dev

and you should see

Running on 127.0.0.1:8000...

Navigate to that URL in your browser and check that you can see the front page.

When running the site in a production environment, instead of make start-dev, run:

make start

Command Line Interface

There is also a CLI available for grading applications on your local machine.

Example usage:

go get github.com/gojp/goreportcard/cmd/goreportcard-cli
cd $GOPATH/src/github.com/gojp/goreportcard
goreportcard-cli
