**Brad Fitzpatrick:** That'll be interesting to see how far they get. It'll be also interesting to see if other languages use Go as their runtime. |
**Erik St. Martin:** Yeah, last week we actually just discussed a project we saw where somebody was implementing the Ruby runtime in Go. I don't know how far along it was, but we did see it. |
**Brian Ketelsen:** Weren't there two of them? Two different Ruby runtimes in Go? |
**Erik St. Martin:** One of them was a Ruby-like language implemented in Go, and the other one was supposed to meet the actual Ruby spec. |
**Carlisia Thompson:** We're talking about languages now, but I'm dying to ask, and other people are asking, as well... Is there any prospect, and how good of a prospect is there if the answer is yes, for Go to have _Generics_? I'm asking this because obviously a lot of people want to know, people ask all the time, and... |
**Brad Fitzpatrick:** Yeah, I think everybody basically wants it; there's not very much anti-generic sentiment on the team. I think we would all like it if we could put algorithms in the standard library, and more containers and data structures in the standard library, or somewhere in some shared library, even if it's ... |
Ian Lance Taylor has written I think five or six proposals at this point, and every time he generally rejects his own proposals. He has even implemented a few of them... So he's probably the one that will figure it out. I don't know if it will be his seventh or eighth proposal he writes... \[laughter\] But I think he's... |
**Carlisia Thompson:** And this is Ian who? |
**Brad Fitzpatrick:** Ian Lance Taylor. Ent@golang, or whatever. He's Ian Lance Taylor on GitHub. |
**Brian Ketelsen:** He's mostly responsible for the GCC port of Go. |
**Erik St. Martin:** Yeah. |
**Brad Fitzpatrick:** Yeah, and he wrote the gold linker. He knows everything about signals and linkers and all this kind of hairy stuff that I don't know. |
**Brian Ketelsen:** The magic stuff that I wanna ignore. |
**Brad Fitzpatrick:** Yeah... Whenever there's some really bizarre UNIX question, like "Here's a process control group with a TTY session leader and something gets a signal and something dies, blah-blah-blah...", he's like "Well, of course... In UNIX, this page of the specification does that, except from that version o... |
The summary is -- I imagine if there's a Go 2, it would have _Generics_. I don't think we would do a Go 2 without _Generics_; it wouldn't be interesting enough. It would be too big of a change to do a Go 2 and break things without it being worth it. I imagine there probably will be a Go 2 at some point, I just don't kn... |
**Erik St. Martin:** Yeah, and I don't think you wanna tell everybody "Generics in Go 3", when they see how long it takes to get to Go 2. They'll know it's never gonna happen. |
**Brad Fitzpatrick:** I also think if there's a Go 2, we can't pull a Python 3 or a Perl 6 and kind of nuke the world and expect things to be okay. |
**Erik St. Martin:** Oh, yeah... |
**Brad Fitzpatrick:** I think any -- I mean, I haven't really thought about the details, but I think if in Go 2 any time you import something, you're allowed to import down... You're allowed to import and use a Go 1 package, but Go 1 packages can't import Go 2 packages, because semantics would be different. I think som... |
**Erik St. Martin:** That's interesting. I think we passed up our second sponsor break, so let's go ahead and take that. Our second sponsor for today is DataDog. |
**Break:** \[50:13\] |
**Erik St. Martin:** Alright, so we are back, talking to Brad Fitzpatrick. We were just talking about a vision for Go 2. Did anybody wanna jump into any interesting projects and news they may have seen this past week? I've got a good one that I saw... |
**Brian Ketelsen:** I have a good one too, so... Go ahead. You go first. Actually, I've got three good ones. |
**Erik St. Martin:** You've got three good ones? |
**Brian Ketelsen:** I've got three good ones, so you go first. |
**Erik St. Martin:** Are you hogging all the good ones? |
**Brian Ketelsen:** Nope. |
**Erik St. Martin:** So I hope I don't butcher his name, but I saw a project called [periph.io](https://periph.io/) by Marc-Antoine Ruel. It's an alternative to [Gobot](https://gobot.io/). It doesn't need any supporting libraries or CGO and things like that... I was chatting with him a little bit about it, and I guess ... |
**Brian Ketelsen:** Sweet... Making barbecues. \[laughter\] |
**Erik St. Martin:** I know... It stinks, because I decided for the meat probes and stuff, like "Alright, I'm just gonna use just a straight ARM processor, just do embedded C", and then I saw that, and I'm like, "Aw... I kind of want a single board computer again now." |
**Brian Ketelsen:** It's okay to change... It is absolutely okay. |
**Erik St. Martin:** It is. |
**Brian Ketelsen:** So I have a cool project and a shoutout that I wanna make... One of our listeners was listening to GoTime while hiking across the Alps, and sent us an email last week about his code generation tool, because he knows how much I like some code generation... |
This code generation tool is at [github.com/dave/jennifer](https://github.com/dave/jennifer), and unfortunately radio is not good for pictures... However, we'll try to find a way to post the picture of Dave standing on top of some giant Swiss Alps mountain, flashing us the Peace sign because he was listening to GoTime.... |
**Carlisia Thompson:** Does Dave have a last name? |
**Brian Ketelsen:** I don't know Dave's last name. I would have to dig up my email to find out Dave's last name. |
**Erik St. Martin:** What does "It is GoTime" announcement sound like after you've climbed a mountain? |
**Brian Ketelsen:** \[laughs\] Heaven. It sounds like heaven. So that was one. Then the other awesome announcement is from [github.com/myitcv/react](https://github.com/myitcv/react), and that is React bindings for [GopherJS](https://github.com/gopherjs/gopherjs). Now it offers Preact support, which is awesome, because ... |
These are specifically cool (these are from Paul Jolly, by the way), because they do code generation for all the yucky stuff. So you just implement a couple interfaces and then type `go generate` and it generates all of the Go code, which then gets transpiled into GopherJS code, which talks to React or Preact. |
**Erik St. Martin:** Brad, you're doing a bunch of GopherJS stuff too, right? |
**Brad Fitzpatrick:** Not so much... Mathieu, who works on Camlistore, is starting to transition more of our stuff to GopherJS and to use React, and I kind of look at it and it makes kind of some sense, but I haven't used much of it myself. |
**Erik St. Martin:** I think React has made me love doing web apps in Go. Before that, it was like a Rails thing, like "Oh, but doing the frontend's hard...", but React is just too easy to build the UI on top of a Go API. |
**Carlisia Thompson:** So Dave's last name is Brophy. |
**Brian Ketelsen:** Oh, thank you. Dave Brophy, you're absolutely right. |
**Carlisia Thompson:** Don't thank me, thank [Florin Patan](https://twitter.com/dlsniper). |
**Brian Ketelsen:** Oh, good job, Florin! That's why we have a pool of listeners in the GopherSlack, to help us out. |
**Erik St. Martin:** Yeah, why are we the hosts? They seem to know more than we do. |
**Brian Ketelsen:** I know. Kind of funny, isn't it? |
**Carlisia Thompson:** They totally do. We just wing it. They do the work, we wing it. |
**Erik St. Martin:** Is this you, Brian, who dropped in the "Is Go 2 actually happening?" |
