It is definitely the case that this behavior of cl-format you demonstrate does not match the behavior of Common Lisp's format when given the same arguments. It doesn't capitalize the keyword name, either, but I think leaving it lower case is more in keeping with Clojure's case-sensitive symbol nat

Re: "Clojure Javadoc API Documentation" needs to be rebuilt.

Others can confirm, but I think that is the entire API, callable from Java, that is documented and supported by Clojure. Everything is reachable from there if you know which Clojure Vars you want to use. Andy On Tue, Sep 29, 2015 at 7:31 AM, crocket wrote: > http://clojure.github.io/clojure/ja

Re: deprecation warnings?

Try out the Eastwood Clojure lint tool [1] and see if it gives deprecation warnings where you hope to see them. Andy [1] https://github.com/jonase/eastwood On Wed, Oct 14, 2015 at 9:31 AM, William la Forge wrote: > OK, but > > 1. Still no warning from cursive or lein test and > 2. I think the

Re: Apparent bug with more than 5000 command line arguments

James: This sounds to me likely to be known and expected behavior of xargs. Any OS has maximum limitations on either number and/or total size of command line arguments, and xargs is probably invoking multiple JVMs. Here is a portion of the man page for xargs on my Mac: Any arguments specified o

Re: ArithmeticException while using unchecked-multiply

I can't answer whether Clojure should do that. It is doing it because unchecked-multiply falls back to normal multiply, i.e. *, unless both of its arguments are primitive long values. Even boxed Long values cause it to fall back to the behavior of *. The same goes for unchecked-add and unchecked

Re: ArithmeticException while using unchecked-multiply

I created this ticket: http://dev.clojure.org/jira/browse/CLJ-1832 I don't know what will become of it, e.g. perhaps a change in behavior to the unchecked functions, perhaps a clarification to the documentation, perhaps nothing. I wouldn't be surprised if the Clojure core team judged the existing

ojure.core/unchecked-subtract Describing the odd behavior in only one of those entries, and then cross-referencing it explicitly in the examples of the others to the 'detailed one', can save redundancy in writing. Andy On Sun, Oct 25, 2015 at 11:17 PM, Andy Fingerhut wrote: > I cr

Results of some testing done on 1.8.0-RC1: Ran 'mvn clean test' on a few OS/JDK combos that are not tested as often. Reason: there have been (or still are) build or test failures with some of them. All JDKs listed below were 64-bit. Windows 7 Enterprise SP1 + Oracle JDK 1.7.0_80-b15: ok 3/3 tria

Re: [ANN] Clojure 1.8.0-RC1 is now available

nearly the same -- about 2% longer with 1.8.0-RC1, but I only ran each set of tests once, and that could be within the range of variability across runs. Andy On Wed, Nov 11, 2015 at 12:02 PM, Andy Fingerhut wrote: > Results of some testing done on 1.8.0-RC1: > > Ran 'mvn clean test&#x

Re: Poor parallelization performance across 18 cores (but not 4)

There is no STM involved if you only have atoms, and no refs, so it can't be STM-related. I have a conjecture, but don't yet have a suggestion for an experiment that would prove or disprove it. The JVM memory model requires that changes to values that should be visible to all threads, like swap!

Re: Poor parallelization performance across 18 cores (but not 4)

David, you say "Based on jvisualvm monitoring, doesn't seem to be GC-related". What is jvisualvm showing you related to GC and/or memory allocation when you tried the 18-core version with 18 threads in the same process? Even memory allocation could become a point of contention, depending upon how
