Installation

Follow macOS instructions here (or just use homebrew).

go run main.go
go build system.go

Local doc. : godoc -http=:6060

go & Heroku

go install github.com/rikwatson/hello

The above command will put an executable command named hello (or hello.exe) inside the bin directory of your workspace. Execute the command to see the greeting:

$GOPATH/bin/hello
hello, world

Environment variables

TODO: Stuff here about $HOME etc. Setting up for development.

echo 'export GOPATH=$HOME' >> $HOME/.profile
source $HOME/.profile
go env | grep GOPATH
GOPATH="/Users/myusername"

export GOPATH=~/Dropbox/go # /Volumes/MICROSD/go
mkdir -p $GOPATH
cd $GOPATH
mkdir -p $GOPATH/src
mkdir -p $GOPATH/src/github.com/raul
mkdir -p $GOPATH/src/github.com/raul/hello-go
cd !$
wget https://gist.github.com/raul/c168e41b78e23414c3b0/raw/hello.go
cat hello.go
go install . # No output means a successful compilation
ls $GOPATH/bin
$GOPATH/bin/hello-go
export PATH=$GOPATH/bin:$PATH  ####### < Add this TODO
mkdir -p $GOPATH/src/github.com/raul/hello-package
cd !$
wget https://gist.github.com/raul/345d9443b97ac394f590/raw/hello.go
cat hello.go
go build .
go install .
ls $GOPATH/pkg/darwin_amd64/github.com/raul/hello-package.a

cd $GOPATH/src/github.com/raul/hello-go
wget -N https://gist.github.com/raul/9e46c9f1d6e4bcd9df96/raw/hello.go
cat hello.go

go install .
hello-go

Go App Engine

Download from here, unzip & then:

export PATH=/path/to/go_appengine:$PATH

Also add to ~/.profile & do a source ~/.profile. Shold know have goapp etc available.

Then a swift

cd 
open http://localhost:8080/
goapp serve .
[Cmd-R]

and we’re in business - edit the .go and it will get recompiler on the fly. REPL..

Comming next look here.

• Concurrency
• Control variance

  AppStats certainly looks interesting. A golang version of the Python package. Also worth looking at the source code as quite performant & possibly similar to what we may end up needing.
