But it solves the common problem in the IT industry.
Before Go, there are only two popular choices to do backend progrmaming, 
Java (as a compiled langauge) and several dynamic languages.
Now Go presents as an alternative to Java, with many advantages to Java.

[go-nuts] Flutter and golang

[Tong Sun]

Saw a recent discussion on Flutter and golang, which seems to me to be 
going the wrong way, because I didn't see the magic word "FIDL 
" being mentioned. So I'd like to 
share my finding about that, 

First of all, about the Flutter:

On February 27, 2018, in Mobile World Congress 2018, Google announced the 
first beta 
 
release of Flutter 
.
 



   - Flutter is Google's new mobile UI framework that helps developers 
   craft high-quality native interfaces for both iOS and Android. 
   - Flutter targets the sweet spot of mobile development: performance and 
   platform integrations of native mobile, with high-velocity development and 
   multi-platform reach of portable UI toolkits.
   

There are loads of articles on Flutter 

 
already, but let me just pick only two:

What’s Revolutionary about Flutter

https://hackernoon.com/whats-revolutionary-about-flutter-946915b09514

Quote:

traditional model layout could be simplified significantly:


   - 
   
   Instead of having a large set of layout rules that could be applied to 
   any widget, each widget would specify its own simple layout model.
   - 
   
   Because each widget has a much smaller set of layout rules to consider, 
   layout can be optimized heavily.
   - 
   
   To simplify layout even further, we turned almost everything into a 
   widget.
   
Second, 

Why we chose Flutter and how it’s changed our company for the better

https://medium.com/@matthew.smith_66715/why-we-chose-flutter-and-how-its-changed-our-company-for-the-better-271ddd25da60

Quote:

Our productivity on new feature development has roughly tripled. Here’s why:


   - 
   
   Not only do we have the obvious gains from having only one code base 
   between iOS and Android, we are able to share ~70% (at the moment of this 
   writing it’s 67%) of our web client code with the mobile clients. But it 
   doesn’t end there. 
   - 
   
   When we test a feature in any of the platforms, unless it’s a platform 
   specific UI change, we are effectively testing across all three platforms 
   at once. We did not expect this gain, but it’s real and it’s significant. 
   
   - 
   
   We also found that because we were able to merge what was a fragmented 
   team into one team with a common skill set, we spend less time being 
   blocked by each other and can more easily work together. And honestly, we 
   are happier. While it’s fun to build a new feature, it becomes a chore to 
   then have to recreate it two more times. Then have to write the platform 
   specific unit tests. Then QA the same thing again.
   

OK, enough about Flutter 
.
 


We all know that recently Google lost its legal battle on using Java, so my 
personal view is that Android would be on the chopping board soon. One hint 
is that Google has silently changed its *Android* play store to *Google* 
Play Store  recently, which means a 
lot to me. 

Anyway, what I'm trying to say is that Flutter 

 
is only a small part of Google's strategic planning to ditch Java, and also 
the two OSs for the mobile phone and pad, the Android & ChromeOS, because 
Flutter 

 
is the center piece of Google's next generation OS, Fuchsia, which will be 
a cross-device OS for Phone, tablet, desktop, laptop, wearables, and more. 

Taken from https://9to5google.com/2018/01/23/what-is-google-fuchsia-os/ 

Most of the Fuchsia's UI is written in Dart  (a 
language that is designed to feel familiar to JavaScript and Java 
developers), through the Flutter framework . Support 
for Go !. Systems 
developers will find comfort in the availability of Rust 
.
 
Google is also targeting Apple’s developer base by introducing Swift support 
.

Once again, the Flutter framework  will support Go 
!  

It has native interoperability support for most of these languages, through 
the FIDL protocol , your Dart UI 
code can directly interface with your Go backend or any other combination. 



Again, the above are all of my finding, and my 2c view on them. 
All in all, I strongly believe that Flutter Will Take Off in 2018

Indeed. Please do not conflate popularity with ubiquity. Formula one is a very 
popular sport, but not everyone needs to do 180mph down the straight away for 
their daily commute.

[go-nuts] colorful go test output

[Alex Efros]

Hi!

When we run `go test` (without package param) it doesn't redirect
os.Stdout, so it's possible to detect is it a TTY and enable color output:
unix.IoctlGetTermios(int(os.Stdout.Fd()), ioctlReadTermios)

But when we run `go test .` (with package param) it does redirect
os.Stdout, so it's became impossible to detect is it a TTY.

Is there any other way to auto-detect is os.Stdout support colors in this
use case? Or should I just introduce env var like $GOTEST_COLOR=1 instead?

I’m not sure popularity is a shared goal in the community; the original

Re: [go-nuts] Re: Is there a memory leak on Rob Pike's demo codes?

['Bryan Mills' via golang-nuts]

To answer the original question about how to detect the leak: if you have a 
leak, the “goroutine” profile from runtime/pprof 
 will show an 
ever-increasing number of goroutines with the same stack trace.

Detecting such a leak in a unit or integration test, however, is fairly 
tricky: you can fairly easily detect that the goroutine count is 
increasing, but it can be tricky to figure out whether that is a leak or 
just a transient increase while the program spools up to a steady state.

Re: [go-nuts] Re: Language is a platform, which golang still does not pay attention to !!!

[Tyler Compton]

Go does not run in a VM like JVM and CLR languages do, but Go provides a
"language as a platform"-like feel by allowing for code that is by and
large platform-independent. It is true that executables have to be built
for each platform but that has benefits of its own. Java applications
require the JVM to be installed, while Go executables work immediately on
the platform without dependencies.

Additionally, I don't really see why having a VM (which I assume is what
you mean by a platform) makes for better language in the cloud space. For
the most part, machines running in the cloud use Linux. If you build your
executable for Linux, you're done. No extra environment configuration
required like one would have to do to run a VM language. Building the
executable is often easy because of Go's great cross-compilation support.
This ease of deployment is something people talk up Go for quite a bit.

If you try Go out, I suspect you won't miss the JVM or the CLR.

As my company is a potential vendor of commercial Go libraries, I've been 
interested in this very question. I believe your assertion is incorrect. It 
is possible, but not pleasant, to share pre-built Go libraries. The 
challenge is that you have to include stub code to make it work, and make 
sure the timestamps on the stubbed-out code don't get updated. Of course, 
you also have to ship the binaries specific to the platform that the target 
developer is going to use, but that is possible. The advantage of shipping 
the stub code is that you can get all the benefits of existing IDE tooling 
that work off of the source to generate documentation, and understand the 
meaning of your code and how it is used.

What is meant by "language as/is platform"? Just about any library I need, 
I can find for Go. And they happen to work across multiple platforms, just 
like with Java. As with Java before it, Go delivers on database APIs, web 
APIs, and protocols. There's a robust ecosystem of third-party libraries to 
make coding in Go much better. Numerous IDEs and editors include excellent 
support for Go.

Tons of community, including Meetups around the world.

One piece that has been missing relates to versions on libraries. That has 
been addressed in various ways, and a proposal that will most likely join 
the toolchain is in the queue for Go 1.11 (vgo).

What would meet the definition of finished? Java still isn't finished, all 
these years later, because they're still adding language features (not just 
libraries!). Is Java slow because of this?

Go has felt to me like it moves very rapidly, as incredible enhancements 
come very quickly to the ecosystem. The compiler is itself now written in 
Go, and most of the runtime, which means that it is more possible for Go 
developers to help tweak the future direction of the language than it is 
for say Java developers, for whom the JVM will mostly be a black-box 
written in C++ that they probably never understand.

[go-nuts] Language is a platform, which golang still does not pay attention to !!!

[bingjunyin]

Almost 10 years golang appears in the world. 10 years is not a short 
duration. I think if it is not popular until 2020, it will never be popular.

Golang is designed for cloud and internet areas. Really?

The creators of golang have a lot of experience in C and C++. And golang 
borrows features from C and C++. But C and C++ do not fit the requirements 
of cloud and internet areas.

Let's look at two popular programming languages java and php. What is the 
most important features of these two languages? Simple, ugly but 
practical... I find one feather: they are both not just programming 
languages but also platforms. They are almost the same in Windows and 
Linux. That's why java and php are very popular in recent days.

C and C++ are just pure programming languages, not platforms. On Unix and 
Windows, C and C++ are very different. A developer of windows C++ is not a 
developer of UNIX C++, and a Linux C developer is not a Windows C developer.

If golang wants to be widely used by developer all over the world before 
2020, it must learn some thing from java and php, must be a 
programming-language-is-a-platform.

Until now, programs written in golang still does not have binary 
distribution format like jar, dll or so. People have to share libraries by 
source code. It is so foolish.

Yes, Golang is very like C and C++, which are only pure programming 
language, But this times, we need "language as/is platform" technologies, 
just like php and java.

I have watched golang for many years, but never turn to it. Why? I think it 
is still semi-finished product. Creators of golang are researchers, not 
engineers, they worked too slow.

Re: [go-nuts] Hosting godoc internally for private git server

[Michael Levine]

How can I make godoc being run on local source code use the godoc 
templates/assets properly from a locally hosted version of godoc?

I tried the following:  $ godoc 
-templates="$GOPATH/src/github.com/golang/gddo/gddo-server/assets" -html 
path/to/local/library > ~/destination/path/library.html

I also found the following notes:

>From (https://github.com/golang/gddo/wiki/Development-Environment-Setup):  
"To run the gddo-server binary outside of a development environment with 
the source in $GOPATH/src/github.com/golang/gddo, you will need a copy of 
the assets directory. Use the gddo-server --assets command line flag to 
specify the location of the directory."

>From (https://github.com/golang/tools/blob/master/godoc/README.md):  "In

a flag to load CSS/JS/templates from disk every time a page loads:$  
godoc -templates=$GOPATH/src/golang.org/x/tools/godoc/static -http=:6060"

Is there a flag I can use when I run godoc to make the proper

Re: [go-nuts] proposal: advise using SetFinalizer to detect resource leaks

[Mateusz Czaplinski]

I replied on the issue; in short, if the proposal gets dismissed, I'll take
my chances at creating a third-party package with some super simple API,
and then try advertising it here, on reddit, and maybe to other packages.

Then why would this need to live in the stdlib? For example here is a quick
and dirty implementation that allows the same functionality, without having
to modify the stdlib:
https://play.golang.org/p/_TsQQUhs8Ik
This could be provided as a normal package and people can use it to augment
any io.Closer (and, really, by extension anything) with this functionality.

Re: [go-nuts] proposal: advise using SetFinalizer to detect resource leaks

[Mateusz Czaplinski]

Reading from it and handling the errors is left to user. There are many
possible ways to handle it, so it's hard to guess in the finalizer what
user wants:
  a) print them on stderr
  b) push them to some logging infrastructure
  c) just plain ignore them (default behavior)
User may not want or expect to have stderr trashed by some messages from
libraries. Passing the errors through a common channel can help opt-in to
the feature.

What would the runtime.Leaks channel do with the received errors? Why can't
you just do the same thing from the finalizer itself?

[go-nuts] proposal: advise using SetFinalizer to detect resource leaks

[Mateusz Czapliński]

Based on a recent discussion on reddit, and a reply by BowsersaurusRex:

"In C# I'll often use finalizers to track bugs in which an object was 
GC'd but Close() was never called."

I submitted the following proposal:

https://golang.org/issue/24696

I'd love to see a solution which would not require adding to package 
runtime, but as of now I don't see how it could be possible — esp. if 
stdlib packages were to use it.

I'm curious what are your thoughts on whether this would be a good idea? Do 
you see some problems with that? Do you think it could be done outside 
standard library?

It's not necessarily a leak. It's a possible leak.

And digging even deeper: it's implementation defined. Non-reachable
channels can be collected and goroutines blocked on them killed without
changing the semantics of the program.
