Re: [ANN] Clojure 1.9.0-RC1

Code with reflection is ~6% faster on server JRE (in 1.9.0-RC1) and ~1% slower on client JRE. So apparently it's not a big deal. Server JRE: user> *clojure-version* {:major 1, :minor 8, :incremental 0, :qualifier nil} user> (use 'criterium.core) nil user> (bench (.length (.toString (reduce (fn

Re: [ANN] Clojure 1.9.0-RC1

Correction - it's not about regex parsing. I removed reflection calls for StringBuilder and now it seems to be on par in speed. On Fri, Nov 24, 2017 at 1:20 AM, Sergey Didenko wrote: > Hi, > > is it expected that code which does a lot of regex parsing is ~14% slower >

Re: [ANN] Clojure 1.9.0-RC1

Hi, is it expected that code which does a lot of regex parsing is ~14% slower than it was under Clojure 1.8? On Tue, Nov 14, 2017 at 8:22 AM, Shantanu Kumar wrote: > Sorry, my bad. I can see the same behavior in previous Clojure versions > too. I discovered this in

Re: [ANN] Clojure 1.9.0-RC1

Sorry, my bad. I can see the same behavior in previous Clojure versions too. I discovered this in the middle of moving to 1.9.0-RC1 in one of the projects and somehow got it all mixed up. Shantanu On Tuesday, 14 November 2017 11:36:30 UTC+5:30, Andy Fingerhut wrote: > > I see the same

Re: [ANN] Clojure 1.9.0-RC1

I see the same behavior in Clojure 1.7.0 and 1.8.0 as you see in 1.9.0-RC1. Andy On Mon, Nov 13, 2017 at 9:48 PM, Shantanu Kumar wrote: > Sorry, I did not specify the problem completely earlier. The coercion > fails only when *uncheked-math* is set to truthy in

Sorry, I did not specify the problem completely earlier. The coercion fails only when *uncheked-math* is set to truthy in 1.9.0-RC1. user=> (byte \a) 97 user=> (set! *unchecked-math* true) ; or :warn-on-boxed true user=> (byte \a) ClassCastException java.lang.Character cannot be cast to

Works for me in 1.9.0-RC1. I don't know of anything that changed in this area. Clojure 1.9.0-RC1 user=> (byte \a) 97 On Mon, Nov 13, 2017 at 1:09 PM, Shantanu Kumar wrote: > The coercion (byte \a) works fine in Clojure 1.8, but it fails with > `ClassCastException

Re: [ANN] Clojure 1.9.0-RC1

The coercion (byte \a) works fine in Clojure 1.8, but it fails with `ClassCastException java.lang.Character cannot be cast to java.lang.Number` in 1.9.0-RC1. Is this by design? Shantanu On Monday, 13 November 2017 07:32:00 UTC+5:30, Alex Miller wrote: > > Hi David, > > Clojure 1.9 now

Re: [ANN] Clojure 1.9.0-RC1

Hi David, Clojure 1.9 now depends on two external dependencies (spec.alpha and core.specs.alpha) so the instructions listed there will no longer work. We are evaluating whether and how to update those instructions in the readme right now. Most Clojure users work with Clojure through a

I'm getting an error when I follow the instructions in the readme.txt, am I missing something? java -cp clojure-1.9.0-RC1.jar clojure.main Exception in thread "main" java.lang.ExceptionInInitializerError at java.base/java.lang.Class.forName0(Native Method) at

Re: [ANN] Clojure 1.9.0-RC1

Clojure 1.9 (and 1.8, and every other prior version of Clojure!) works with Java 9 due to the care that Java takes in retaining backward compatibility. Clojure 1.0 works just fine with Java 9. However, there have been some changes that affect various tools, most prominently Leiningen and Boot.

One more data point. I haven't uncovered any regressions yet on beta4 & have upgraded a few libraries and apps; though none are in production yet I've been working with it more or less daily since the beta4 release. R. On 7 November 2017 at 14:58, Alex Miller wrote: >
