Have you ever noticed how Go community presents Go-related talks? Their slides are very simple and without any fancy animation features: see Go talks. You might say that they are no so feature-rich as Reveal.js. And it’s true. But, simplicity is beauty, as for me. Also, it’s very well aligned with Go language philosophy.

So, here is listed steps required to setup and run Go present tool.

Install Go

I use Mac OS X in this tutorial (see the next article to install Go on other *OS*es).

Install Go:

$ brew install go

==> Downloading https://homebrew.bintray.com/bottles/go-1.4.2.yosemite.bottle.1.
######################################################################## 100.0%
==> Pouring go-1.4.2.yosemite.bottle.1.tar.gz
==> Caveats
As of go 1.2, a valid GOPATH is required to use the `go get` command:   https://golang.org/doc/code.html#GOPATH  

You may wish to add the GOROOT-based install location to your PATH:
  export PATH=$PATH:/usr/local/opt/go/libexec/bin
==> Summary
🍺  /usr/local/Cellar/go/1.4.2: 4566 files, 155M

Define Go workspace

Let’s assume that our Go language workspace will be located at /Users/halyph/Projects/go:

$ mkdir go
$ pwd
/Users/halyph/Projects/go

Configure PATH variable

$ cat .bash_profile

#Golang settings
export PATH=$PATH:/usr/local/opt/go/libexec/bin
export GOPATH=$HOME/Projects/go  #/Users/halyph/Projects/go
export PATH=$PATH:$GOPATH/bin

Install Go present tool

present tool is located in separate package golang.org/x/tools which depends on golang.org/x/net package:

$ go get golang.org/x/net
$ go get golang.org/x/tools
$ go install golang.org/x/tools/cmd/present

Now, we can find present tool here:

$ which present
/Users/halyph/Projects/go/bin/present

Run present tool

The easiest way to test present tool is to render some slides:

$ cat sample.slide

$ present

You should see something like this:

Go present works and you are ready to produce Go-fashion slides.
