This article walks through the installation process.

Install Go

To use Revel, you first need to install Go.

Set up your GOPATH

If you did not create a GOPATH as part of installation, do so now. Your GOPATH is a directory tree where all of your Go code will live. Here are the steps to do that:

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 GOPATH=$GOPATH >> .bash_profile

Now your Go installation is complete.

Install git and hg

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

• Installing Git
• Installing Mercurial

Get the Revel framework

To get the Revel framework, run

go get github.com/robfig/revel

This command does a couple things:

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

Build the Revel command line tool

The Revel command line tool is how you build, run, and package Revel applications.

Use go get to install it:

go get github.com/robfig/revel/revel

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

export PATH="$PATH:$GOPATH/bin"
echo 'PATH="$PATH:$GOPATH/bin"' >> .bash_profile

Lastly, let’s verify that it works:

$ revel help
~
~ revel! http://robfig.github.com/revel
~
usage: revel command [arguments]

The commands are:

    run         run a Revel application
    new         create a skeleton Revel application
    clean       clean a Revel application's temp files
    package     package a Revel application (e.g. for deployment)

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

Now we are all set up.

Next: Create a new Revel application.
