Pythia is a browser based user interface for the Go source code guru,
which is a tool for navigating Go code.
For more information on the Go guru, see Using Go Guru.

Installing from source
Building Pythia requires Go with module support (Go 1.11 or later).
To install, run
$ git clone https://github.com/fzipp/pythia
$ cd pythia
$ go install
You will now find a pythia binary in your $GOBIN or $GOPATH/bin directory.
Running Pythia also requires guru:
$ go get -u golang.org/x/tools/cmd/guru
Usage
Start the web application with a package path, e.g.:
$ pythia net/http
By default it will listen on port :8080 and try to launch the application
in your browser. You can choose a different port via the -http flag, e.g.:
$ pythia -http :6060 fmt
Run pythia -help for more information.
