[ANN] Clojure 1.10.0-beta1

[Alex Miller]

1.10.0-beta1 is now available. You can try it with clj using:

      clj -Sdeps '{:deps {org.clojure/clojure {:mvn/version "1.10.0-beta1"}}}'

1.10.0-beta1 includes the following changes since 1.10.0-alpha9:

• Revert change for CLJ-1550 - Classes generated by deftype and defrecord don’t play nice with .getPackage
  
• Revert change for CLJ-1435 - 'numerator and 'denominator fail to handle integral values (i.e. N/1)
  
• Add changelog since 1.9
  
• Mark prepl as alpha
  

[Alex Miller]

Now is a great time to try 1.10.0-beta1 and let us know if you find any major bugs or performance issues. 

I also meant to mention that all changes in Clojure 1.10 are now collected in the changelog:

    https://github.com/clojure/clojure/blob/master/changes.md

At this point, we consider 1.10 to be feature complete and only plan to address critical bug fixes so we can move expeditiously towards a final release.

Looks good to me, tested on both prod and open source code.

Thank you! We’re already on Alpha 8 in production, and we upgraded to Alpha 9 in dev today. We’ll get Beta 1 onto dev and into QA on Monday and I expect we’ll take it to production early next week.

 

Will there be more detail about prepl in a blog post or similar?

Cool! Will there be more guides how to use tap and prepl ?

Is there any plans to release  clj for windows?

Mike.

I’m not sure a guide is needed for tap - the functions are pretty simple? I’ll think about it.

prepl is designed for tool makers so is probably a limited audience and not really a good target for a guide. The docstrings have a lot more detail and may lead to some updated reference material.

Yes, but I can’t give you a timeframe. Significant work has been done.

[Alex Miller]

Thanks for testing!

This is very appreciated that it is now easy (and not only simple :) ) to test new Clojure versions with Clojure CLI: 

      clj -Sdeps '{:deps {org.clojure/clojure {:mvn/version "1.10.0-beta1"}}}'

Personally, I understand the mechanics, but I have no idea how they're intended to be used. I'd love to see some examples of what they're designed to do.

[Bozhidar Batsov]

Same here. 

[Alex Miller]

In a situation where you want to understand values flowing through some point in your system, you might use println or logging to understand what is flowing. 

What are the problems with println/logging?

- both: about strings, not values

- both: hard-wires the putting of the value to where the value goes (log f/ws have some flexibility there)

- logging: requires you to add logging crap to your requires and deps

- println: hard-wires where things go to a stream that's difficult to rebind in a global way

tap is a means to convey values (not strings) via a queue (see: Language of the System) where you can dynamically choose to attach and detach handler(s) to tell it to put values wherever you want (a log, a metric, println) - but those are decoupled from where you convey the values. tap> is in core so it's as easy to add to your code as println.

I recently stumbled across this little example by Ghadi Shayban that helped both prepl and tap click for me:

$ clj -Sdeps '{:deps {org.clojure/clojure {:mvn/version "1.10.0-beta2"}}}'

Clojure 1.10.0-beta2

user=> ;; launch a nested PREPL that steals this REPL’s *in* / *out* streams

user=> (clojure.core.server/io-prepl)

:bar

{:tag :ret, :val ":bar", :ns "user", :ms 0, :form ":bar"}

(defn my-broken-function [x]

  (tap> x)

  (prn "some output")

  (tap> x)

  :bar)

{:tag :ret, :val "#'user/my-broken-function", :ns "user", :ms 223, :form "(defn my-broken-function [x]\n  (tap> x)\n  (prn \"some output\")\n  (tap> x)\n  :bar)"}

(my-broken-function 24)

{:tag :out, :val "\"some output\"\n"}

{:tag :ret, :val ":bar", :ns "user", :ms 2, :form "(my-broken-function 24)"}

{:tag :tap, :val "24"}

{:tag :tap, :val "24"}

:repl/quit

nil
