Is it just me or Golang started gaining momentum recently? More and more related articles/OSS projects/HN links show up every day.

When I first saw Go I was put off by its syntax, but after giving it a chance I very quickly fell in love with it. I've used C#, Python, Ruby, Java, C, Obj-C, JS and Go for mid-large scale projects. Go is the only language I've ever truly loved; sometimes I even feel like I'm writing poetry (as ridiculous as that may sound). The community is really incredible^, I've yet to encounter anything that didn't have great do…

Genuine question as I've only dabbled in Go, but I've heard complaints from other dabblers that Go seems to encourage large files rather than breaking things up in a more modular fashion. Is that a reality? Or has the complainer just been unlucky in the code they've viewed?

I don't see any reason why Go would encourage large files. A Go package consists of every Go source file in a directory. You can use as many or as few files as you want per package.

Upon reading the title I wondered "would anyone ever create a VPN client that doesn't use encryption?" and thought, with the "2k lines" as additional evidence, that it was the source code which was somehow encrypted/obfuscated to e.g. prevent censorship...

I was also expecting to see a single file at that line count, but then again I'm not really familiar with Go. Is this style of "many tiny files in multiple nested directories" common/expected for Go? I know it's rather common in many other languages, but also not what I expect when I see "Simple" or explicit mention of a low line count.

Yeah, I found it a strange assertion to make, so was wondering if it held any water. Sometimes different languages have different ways of working, which seem odd to novices entering the space from a different background, so I didn't want to assume that they were wrong.

Looks like it may be a case of coming across some less well written projects and making assumptions about the entire language, which is nice as Go seems fun :)

I have been using Go for about 4 years at work and I would say they have been unlucky with the code they have looked at. You have the freedom to organize your code as you wish, you can easily go from one extreme to the other, one function per file to 1000 in one file. The only thing that isn't encouraged is to have very small packages, for example, if your project ends up split into 10 packages, but each of them is just one file (or one code file plus a test file), then most Go developers would suggest to group more files into a single package.

I wouldn't use that repo as a representative of what "go code looks like". Most go repos are pretty similar in "structure", but I really don't know how to navigate this. The 'src' directory looks like the author is really fighting the gopath concept, but also trying to vendor dependencies. I agree, if my hook was "in xx lines of code" I would try to avoid boilerplate and keep it all together as much as possible.

We don't really have the "one class one file" beat into us like in java or c#. That means you gotta think a little to see how a package naturally splits up. Some people are better at that then others.
