Google Releases Version 1 of Go Programming Language

Google Inc. this week released version 1 of its Go programming language. The release was announced on the Go Programming Language Blog in a post by Andrew Gerrand, developer advocate for Go at Google Sydney.

Go is an open source systems programming language that was first announced in 2009, after being internally developed at Google since 2007. In the Go FAQ, Google describes Go as "mostly in the C family (basic syntax), with significant input from the Pascal/Modula/Oberon family (declarations, packages), plus some ideas from languages inspired by Tony Hoare's CSP, such as Newsqueak and Limbo (concurrency)."

Go version 1 (Go 1), which Gerrand referred to as a "major milestone," is the first release that promises stability with future iterations of the language, according to the company.

In his blog post, Gerrand noted that Go 1 is "not a major redesign," but rather provides a new standard for the Go language so that developers can confidently use it to build stable products. He discussed some of the primary reasons for the release of Go 1, including "forward compatibility," updates to the language and its standard library, and the introduction of a new go command. Gerrand described the go command as "a program for fetching, building, installing and maintaining Go code."

The Go 1 release also makes the language usable on different platforms. "Go 1 is the first release of Go that is available in supported binary distributions. They are available for Linux, FreeBSD, Mac OS X and, we are thrilled to announce, Windows," Gerrand explained.

A new version of the Google App Engine SDK was released concurrently with Go 1. Gerrand noted that, like Go 1, the new App Engine release is intended to provide a stable base for current and future development.

 

Description

The syntax of Go is broadly similar to that of C: blocks of code are surrounded with curly braces; common control flow structures include for, switch, and if. Unlike C, line-ending semicolons are optional; variable declarations are written differently and are usually optional; type conversions must be made explicit; and new go and select control keywords have been introduced to support concurrent programming. New built-in types include maps, Unicode strings, array slices, and channels for inter-thread communication.

Go is designed for exceptionally fast compiling times, even on modest hardware. The language requires garbage collection. Certain concurrency-related structural conventions of Go (channels and alternative channel inputs) are borrowed from Tony Hoare's CSP. Unlike previous concurrent programming languages such as occam or Limbo, Go does not provide any built-in notion of safe or verifiable concurrency.

Of features found in C++ or Java, Go does not include type inheritance, generic programming, assertions, method overloading, or pointer arithmetic. Of these, the Go authors express an openness to generic programming, explicitly argue against assertions and pointer arithmetic, while defending the choice to omit type inheritance as giving a more useful language, encouraging heavy use of interfaces instead. Initially, the language did not include exception handling, but in March 2010 a mechanism known as panic/recover was implemented to handle exceptional errors while avoiding some of the problems the Go authors find with exceptions.

Go interfaces do not participate in a type hierarchy like Java's. They are better described as a set of methods, identified by their name and signature. An interface can be declared to embed other interfaces, meaning the declared interface borrows the methods defined in the other interfaces, making them part of the set of methods of the declared interface. A type matches an interface if it defines the methods (same name and same signature) from this interface.

Visibility of structures, structure fields, variables, constants, methods, top-level types and functions outside their defining package is defined implicitly according to the capitalization of their identifier.

Examples

package main


import "fmt"


func main() {

fmt.Println("Hello, World")

}

   
  
 
 
   

 
 
Very interesting Language BY Google.......
 
Wonder if i should learn it
 
wow, this was expected lol
 
MAD!!!! WOW!!! Looks like they did it again
 
It looks kinda easy to learn... Or is it just me
 
This is interesting to know about "GOOGLE" improvement in standard of quality and their development towards the programming world.
 
Well said JanWan!
 
I have actually started my quest in the Go programming language! i'm very excited..........
 
Google soon make their own OS
