Google Corporation’s GO Language is latest, highly comprehensive and effective system’s language.

GO is an open source project, distributed under a BSD-style license.

"GO combines the development speed of working in a dynamic language like Python with the performance and safety of a compiled language like C or C++," according to a Google blog post.

GO which is expressive, concurrent, and garbage-collected language as their Home Page says.

First of all I would like it if you also try GO’s power. Please use following instructions. (If you are familiar with any Programming Language, it will be more helpful you).

GO is not a Platform independent. I think that is the worst-case that affect GO to spread. It’s works on Linux and Mac Platforms. But even it’s not support to windows platform; it’ll conquer the programming language world as seen on above picture.

Remember all of GO Language most likely to C Language and it is very easy if you are familiar with C Language. And following instructions are for who works on linux platforms.

i.Install by using apt-get via bison parser generator.

ii. To build the Go distribution and run

1. gc Go compiler and tools (6g, 8g etc.).

2. Uses gccgo, a more traditional compiler using the GCC back end.

Here you can see how to install and uses GO with first approach.

The Go compilation environment depends on three environment variables that you should set in your .bashrc or equivalent, plus one optional variable.

The root of Go tree. Typically this is $HOME/go but it can be any directory.

$GOOS and $GOARCH :

Above diagram shows what OS ($GOOS) going to use and the architecture ($GOARCH ) used. Choices of Architectures are 386 (x86 32bit), amd64 (x86 64bit or most mature port), arm (32bit Arm, an incomplete port).

$GOBIN (optional):

The location where binaries will be installed. As on Java it will be on default at C:\Program Files\Java\jdk1.6.0_03\bin . In GO language default is $HOME/bin. After installing, you will want to arrange to add this directory to your $PATH,

This is an example for above :

And After you setting those variables you can check if those are set properly or not, type following on terminal:

Simple Hello World Program:

package main
import fmt "fmt" // Package implementing formatted I/O.
func main() {
fmt.Printf("Hello, world;\n")
}

Output file which is compiled will be file.6 for amd64 architecture. It will be ‘8’ and ‘5’ for 386 and armare architectures.

• Save this text as helloworld.go
• Compile it 6g compiler for Go Lang(amd64).
$ 6g file.go
• To link that file use
$ 6l file.6
• To run that use
$ ./6.out

Remember GO is just released and there will be some bugs and so many incomplete things.!

A Gopher :

A gopher is a small burrowing rodent that comes in many varieties. - Wkipedia

When looking at the above picture we can see those above logos are look like same. Yes it’s true. Both have same animal called gopher and designed by same person. PLAN 9 is a Bell Labs project and it is designed by Renee French.

PLAN 9 from Bell Labs is distributed operating system.

GO is an experiment. Also it is just at experimental level. But Google use it for some cases and in future they will broadly use GO.

For example GO is used for server behind http://golang.org .

Some parts of GO are object oriented and some parts are structured style.
