Re: numeric-tower versus clojure 1.9

[Mark Engelberg]

You seem to be requiring the numeric-tower functions into the foobar.core
namespace, and then "use"ing the foobar.core namespace from the user
namespace and expecting the numeric-tower functions to show up in the user
namespace.  However, namespaces aren't transitive like that.  You need to
require math.numeric-tower from user if you intend to use it from user, or
change your namespace to foobar.core in the REPL.

A further problem (based on your github issue) may be that your foobar.core
namespace is in a file called src.clj (and you don't say what directory
that file is in).  Usually, the system will expect foobar.core namespace to
be in a file called core.clj in a directory called foobar.

Maybe it isn't a cider problem, I'm having a similar issue with lein.  
Working in the project directory created by lein:

$ lein repl

It seems that the lein repl also is not processing the

line in project.clj.

On the other hand:

nil

Re: [ANN] Datomic Cloud

[Gal Dolber]

Given that Datomic Cloud is just a different implementation for the Client
API you could use an on-prem or in memory transactor for the dev/test
environments. I think aside from performance and load testing there's no
good reason to run tests on a solo instance.

I can't reproduce this problem in either a lein repl or clj repl using

Re: [ANN] Datomic Cloud

[Julio Barros]

So, let me know if I understand this correctly. It seems that this would have 
some challenges such as:

- a single shared instance would require creating and destroying different 
(isolated) dbs for each developer and test runner
- or your organization needs to have enough aws sophistication to allow every 
developer / tester to spin up a solo db on demand.
- actually spinning up an instance would take some time so that needs to be 
planned around
- you have to be connected to do any development or testing

Any clarification would be welcomed?

Is the client api in starter close enough to use for development? Is there 
anyway that can be moved into a developer friendly license?

Thanks.

Julio

[ANN] clojure tools 1.9.0.309, tools.deps.alpha 0.5.323, tools.gitlibs 0.2.47

[Alex Miller]

This morning there are new releases of Clojure tools 1.9.309, 
tools.deps.alpha 0.5.323, and tools.gitlibs 0.2.47.

Highlights (across one or more of these releases):

  * NEW clj -Spom emits dep exclusions and classifier
  * NEW clj -Spom can also be used with -R and -C (but only for top-level 
modifications)
  * NEW pom file reader for local and git deps
   one note is that this will read  as the 
source path, which defaults to src/main/java
   if you are using it with Clojure source, you should probably set 
that to src/main/clojure
   given that most existing Clojure poms don't do this, we may just add 
this automatically instead
  * FIX git deps now use :deps/root if specified - thanks Dominic Monroe!
  * FIX  major updates in transitive version selection
  * ENHANCE git dep :sha now requires a full sha
  * ENHANCE git version resolution now uses stricter rules in comparison
   either both deps must be the same url, or both repos must include 
both commits
  * ENHANCE dump stack on unexpected errors for debugging
  * NEW gitlibs cache location can be modified with GITLIBS env var - 
thanks Pierre-Yves Ritschard!

Re: numeric-tower versus clojure 1.9

[Alex Miller]

I can't reproduce this problem in either a lein repl or clj repl using 
math.numeric-tower + clojure 1.9. Looking at the code, I don't see anything 
that should be different with Clojure 1.9.

[ANN] Clojure By Example: IN/Clojure'18 workshop source material

[Aditya Athalye]

Hello,

I'd like to share the material (source code etc.) for a Clojure workshop 
for programmers.

The material supported a 1-day guided workshop conducted at the 
recently-concluded IN/Clojure conference in Bangalore, India 
(http://inclojure.org/).

While the material is most fun and effective in a live interactive session, 
we've documented it heavily so one may follow along at home too.

The README explains more (study goals, setup, design perspective).

The source is available here: 
https://github.com/inclojure-org/clojure-by-example

My friends[1] and I enjoyed making and teaching this material.

We hope it will be another useful entry point into the weird and wonderful 
land of Clojure.

Sincerely,
Aditya

Re: numeric-tower versus clojure 1.9

[Bozhidar Batsov]

I also got a CIDER ticket about pretty much the same problem
https://github.com/clojure-emacs/cider/issues/2169

I guess there's some problem with Clojure 1.9 and the tower, but I'm not
sure about its exact extent.
