Can someone give me a compelling reason to start programming in Go? My default language at the moment is C, or C++.

Once Go is installed, I can make a simple web app from scratch that displays parameters from the URL or request body in just over 95 seconds with Go, using only the standard library. I can cross-compile it for another OS and architecture, then deploy a single binary file without worrying about dependencies, dynamic linking, or segfaults. Try doing that in C/C++. Maybe a better comparison is to more systems-level appl…

Concurrency with goroutines and channels in Go is pretty awesome, as is the tooling: race detection, code formatting, PPROF performance monitoring, vetting (finding incorrect printf strings), and a great test framework with parallel execution support. The standard library is enough for most of what you'll need, and it's all open source, so you can learn to write idiomatic Go from it.

Also can someone please give a brief description of whole process to write a simple Android app in Go? What are the bare bone setup(Go, JDK, Android SDK??, etc.), so I can develop and compile? Is the final result an apk file? Thanks.

I'm not an Android developer, but have you seen the examples yet? https://github.com/golang/mobile/tree/master/example

I am also not an Android developer, so don't know how to get started using Go for Android. Do I need to set up a Java skeleton first so it can call my Go code? Use Android Studio or other IDE? libraries needed? You know the basic set up and steps for producing a 'Hello World' app. If the instruction is already out there somewhere, I will be very glad to check it out. Golang for Android app, this is exciting.

Just to make sure I'm not missing it: fsnotify didn't make it into Go 1.4, right? 1.5 maybe? :)

Pardon my ignorance but if fsnotify is not available how is Hugo (static site generator) listening for events in the filesystem (to reload the server)

I wonder why they didn't move the main code repo to GitHub as well. https://go.googlesource.com/ is somewhat poor compared to GitHub.

Because we want a good code review system, and GitHub doesn't have that.

By using platform-specific cgo calls.

Probably unimportant for the asker, but go-fsnotify uses syscalls, not cgo.

Now you can write Android application and eventually iOS ( I don't know if I need that ), this is quite interesting. Congrats go team !

Did I miss something? I didn't see anything about iOS.

gophers,

I'm happy to announce that the iOS port of Go recently gained full cgo and external linking support.

I've also got a simple C based application working on a real iPad.

The port lives in ios3 branch of https://bitbucket.org/minux/goios. Read misc/ios/README for some rudimentary documentation.

The port is Go 1.4+, and it's based on upstream dev.cc branch. I intend to propose for inclusion into Go 1.5 after finding a way to test it (either build each test as an App, or use the open source xnu/arm port). Brad mentioned that inclusion of iOS support might happen in Go 1.5 in his talk the state of the gopher (http://talks.golang.org/2014/state-of-the-gopher.slide#40), now I believe it really will happen.

The iOS port is my first Go OS port, but it's the only one that takes almost 3 years to complete. :)

Go build iOS Apps. Let's see when can we see a Go based App in the store.

> The most notable new feature in this release is official support for Android. Using the support in the core and the libraries in the golang.org/x/mobile repository, it is now possible to write simple Android apps using only Go code. This is fantastic! Are there any example Android apps released by the Go team to help get started ?

If go code can now run on android, the go compiler can run on it...? Allowing go coding on-the-unit.
