Let's Learn Go

(Note: nothing is right here! that's just some notes while i was learning)

Get started from here

The first crazy thing, i'm using cygwin on holy windows(R) . when you are setting $GOPATH it detects absolute unix paths as relative path and export GOPATH=`pwd` seems not working. so workaround is GOPATH=`cygpath -aw .` (maybe i will make a helper script for this GOPATH thing)

So lets compile and test my hello-go

mkdir -p src/github.com/pi0/letsgo
vi src/github.com/pi0/letsgo/hello.go

package main

import "fmt"

func main() {
    fmt.Printf("hello, دنیا\n")
}

> go install github.com/pi0/letsgo
[Silent!]
> ./bin/letsgo.exe
hello, world
> du -h ./bin/letsgo.exe
2.4M    ./bin/letsgo.exe

GOPATH Su**s everywhere!

On windows i created a .go directory inside my home dir and set this environment vars:

GOPATH=C:\Users\pooya\.go
PATH=....;C:\Users\pooya\.go\bin

Also there is a useful command go env to test current Go environment configs.
