Install Go

Before you can use Revel, first you need to install Go.

Set up your GOPATH

If you have not created a GOPATH as part of the installation, do so now. The GOPATH is a directory where all of your Go code will live. Here is one way of setting it up:

  1. Make a directory: mkdir ~/gocode
  2. Tell Go to use that as your GOPATH: export GOPATH=~/gocode
  3. Save your GOPATH so that it will apply to all future shell sessions: echo export GOPATH=$GOPATH >> ~/.bash_profile

Note that depending on your shell, you may need to adjust (3) to write the export into a different configuration file (e.g. ~/.bashrc, *~/.zshrc, etc.).

Now your Go installation is complete.

Install git and hg

Git and Mercurial are required to allow go get to clone various dependencies.

Get the Revel framework

To get the Revel framework, run

go get

This command does a couple of things:

  • Go uses git to clone the repository into $GOPATH/src/
  • Go transitively finds all of the dependencies and runs go get on them as well.

Get and Build the Revel command line tool

The revel command line tool is used to build, run, and package Revel applications.

Use go get to install:

go get

Ensure the $GOPATH/bin directory is in your PATH so that you can reference the command from anywhere.

export PATH="$PATH:$GOPATH/bin"

Verify that it works:

$ revel help
~ revel!
usage: revel command [arguments]

The commands are:

    new         create a skeleton Revel application
    run         run a Revel application
    build       build a Revel application (e.g. for deployment)
    package     package a Revel application (e.g. for deployment)
    clean       clean a Revel application's temp files
    test        run all tests from the command-line

Use "revel help [command]" for more information.

Next Create a new Revel application.
