Generators and Fibers

[Oobert]

It would be nice to get some background on them. Some pros and cons and what are people's experiences are with them. Much like the docker show.

[vincentmac]

I'm interested in generators too.

[bmeck]

@dshaw much has changed in this landscape; I am name dropping since twitter said to post opinions here but I feel like stale issues wouldn't be bumped

[dshaw]

@bmeck Realistically, what needs to happen is for a show to come together is it needs a list of candidates for the show and a list of topics (e.g. #9 ). Want to organize this one? Who else would be on?

[rvagg]

perhaps pulling petkaantonov in to this to talk about his workers PR in io.js would be a way to tackle this, it's inching closer to being merged

[dshaw]

And Jafar Husain, maybe?

[bmeck]

I'll try and organize it, but I don't have the muster to host it.

Suggested Panel:

• Petka Antonov (workers: initial implementation nodejs/node#2133)
• Luke Hoban (https://github.com/lukehoban/ecmascript-asyncawait
• Jafar Husain (https://github.com/jhusain/asyncgenerator)
• Someone from Meteor? They are the last bastion of Fibers to my knowledge (suggestions?)
• Alex Rauschmayer (http://www.2ality.com/ , http://exploringjs.com/)

Topics:

• Purpose of:
  • Generators
  • Fibers
  • Workers

Questions about each:

• Current tooling to get these
• Use cases for these
• Combining these with async tasks (cover queueing work and waiting on reply at minimum)

Status:

• Workers PR
• Async/Await wrt. Generators
• Async Generators

[dshaw]

I'll reach out to some folks at Meteor

[dshaw]

I invited @debergalis.

[dshaw]

@bmeck We can sort out hosting. @rvagg, @timoxley or I could host. That said, I would really like to have you on this panel because I'd love to hear your thoughts on this.

[benjamn]

I can talk about why we use Fibers (aka coroutines) at Meteor.

Credentials: I work at Meteor, and I gave this talk at GOTO Chicago a couple months ago: http://benjamn.github.io/goto2015-talk

[benjamn]

Oh, also, I'm the primary author of https://github.com/facebook/regenerator, which seems relevant?

[debergalis]

Thanks @dshaw. You want @benjamn from Meteor.

fibjs vs node.js , see https://github.com/xicilion/fibjs

If any one wants to know about examples of heavy usage of generators for CSP, concurrency, parrallelism:

• A JS library http://github.com/yosbelms/getjs
• A language that compiles to JS http://github.com/yosbelms/cor
