Consider splitting out !-notation into separate repo?

[benhutchison]

Currently, DSL bundles alot of loosely related functionality together. I would like to access the !-notation feature in a modular way.

I didn't grasp the benefits of the !-notation when you first presented at REA FP guild (in the Each project), but I have since better understood the potential and would like to trial it. I write mostly monadic code nowadays, so any way to reduce "friction" can have a big payoff.

However, Im not going to take such big dependency as whole of DSL ATM, but if !-notation was more modular I would try using it (Ive been burned by large codebase dependencies in the past, most notably Finagle which didnt support 2.11.x for ages, just because some small parts of it didnt).

Please consider splitting out !-notation and supporting machinery (eg reset all plugin) into separate repos/artifacts.

They are separate artifacts but not separate repositories at the moment.
Do you suggest to split them into different repositories?

The current code base is modular at the artifact level.
https://github.com/ThoughtWorksInc/Dsl.scala/blob/master/build.sbt#L26

Most of keywords depend on only the core Dsl library or Shift keyword.

[benhutchison]

Yes I suggest independent repos. Finagle was similar to your layout. Independent artifacts, one repo and a master build.sbt. we depended only on 1 of 20 pieces, but had to wait 6-9months for all 19 others to Support scala 2.11. That's why I distrust large multi project repos now. Your DSL project could suffer the same problem with 2.13 for example

If I understand correctly, the actual need is separating version number.

[benhutchison]

What Im after is "confidence that the libraries I depend upon will be not entangled with unrelated code or concerns."

That's broader than just a technical concern, it also touches on project culture & human behavior.

I feel that many aspects of multiple-projects-in-single-repo encourage entanglement, and its only through careful discipline that unrelated libraries in same repo can remain modular.

Examples of issues:

• Shared releases across unrelated libraries (as in DSL at present)
• Github Releases are per-repo so encourages this behavior as a default
• A build.sbt file assumes a single shared scalaVersion
• Single queue for PRs across all subprojects
• Single README file means docs cannot focus on a single library or tool

While many of these can be overcome, the defaults for a github repo all encourage entanglement.

Fair enough! However multiple of repositories also means multiple of efforts to maintain those repositories.

Would you like to be a maintainer of some of the split projects?

[benhutchison]

I'm happy to help maintain repos for tools/libraries that I use ongoing. At this point, Im wanting to trial the use of the monadic !-operator, so Im not yet sure if I will adopt it. How about I trial it and then respond back..

Really nice to hear that! Do you have any plan? 2018-03-30 21:46 GMT+08:00 Ben Hutchison <notifications@github.com>:

I have some Eff-centric codebases where I'll try introducing the monadic operator. I'll probably decide within a month whether it's something to continue with.I'll aim to provide some feedback by end of April. On Mon, Apr 2, 2018 at 2:36 AM, 杨博 (Yang Bo) <notifications@github.com> wrote:

Cool. Enjoy it. You may also consider directly creating some Dsl type class instead Monad. The Dsl type class can interpret keywords, similar to Free monads, except Dsl is open for extending while Free monads are sealed. 2018-04-02 7:34 GMT+08:00 Ben Hutchison <notifications@github.com>:
