2016-09-25 Thread Nikita Prokopov 
Matan,

spec is pretty isolated part of Clojure, so it’s basically a copy-paste job
with couple of gaps filled in that were introduced in 1.9.

Updating it is basically getting diff from clojure and applying it to my
repo. Sometimes with some manual corrections.

Nikita.

Nikita, this is cool, e.g. as lighttable does not yet fully support 1.9. 
Can you say something about how are these backports derived? so that I can 
get an intuition into how much it is at par with the real thing?
Does it involve a lot of code rewrite to backport each 1.9 alpha version?

Did you read my whole question? It doesn't work to have the implementation 
namespace require the spec namespace either, as I demonstrated in my second 
example, where the spec for the factor function uses the prime? predicate.

I can’t help but think you’re making it way more complicated than it needs to 
be.

Define ::config in example.spec, and in example.core use :example.spec/config 
(and, yes, require the example.spec namespace).

You need to avoid circular namespace dependencies.

Thanks Sean. You make an excellent point with specs being in a
separate namespace. I had thought that using fdef would have prevented
doing something like this but it appears I am wrong.

clojure.java.jdbc solves that by having the specs in a separate namespace (and 
by the tests conditionally loading that and clojure.spec.test). 
clojure.java.jdbc supports back to Clojure 1.4.

Nikita, it would be interesting to know how far back (in Clojure versions) your 
library could support. I can see real value in being able to back port spec 
beyond 1.8…

This looks great Nikita.

Sean, a lot of library developers still want to support Clojure 1.8,
but this would prevent using spec with their projects. This would help
there. Onyx in particular was going to avoid using spec for the time
being, but we may re-evaluate now.

2016-06-29 Thread Sean Corfield 
Interesting idea.

 

If you’re already on Clojure 1.8, I think it’s pretty safe to upgrade to the 
Alpha builds of 1.9. We’re running 1.9 Alpha 7 in production at the moment (and 
will move to Alpha 8 in our next build after today).

 

The only glitches we ran into were name collisions in libraries due to new 
predicates being added to core, and only one of those caused an actual breakage 
– and those libraries all got updated very quickly (big thanks mostly to Peter 
Taoussanis for the fast responses).

:dependencies [

  [org.clojure/clojure "1.8.0"]

  [clojure-future-spec "1.9.0-alpha8"]

]

 

(require '[clojure.spec :as spec])

(require '[clojure.spec.gen :as spec.gen])

(require '[clojure.future :refer :all])

 

clojure.future namespace contains all new clojure.core functions like int?, 
seqable? etc

 

The version numbers will follow clojure 1.9 versions. Expect this lib upgraded 
with every new Clojure alpha release until 1.9 if finally out.

[ANN] clojure-future-spec, a backport of clojure.spec for 1.8

2016-06-29 Thread Nikita Prokopov 
Hi!

Not sure if a good idea or bad, but if you were eager to play with latest 
version of clojure.spec but don’t want to upgrade your production to alpha 
version of the language, you can add clojure.spec capabilities as a library 
to 1.8:

https://github.com/tonsky/clojure-future-spec

:dependencies [
  [org.clojure/clojure "1.8.0"]
  [clojure-future-spec "1.9.0-alpha8"]
]

(require '[clojure.spec :as spec])
(require '[clojure.spec.gen :as spec.gen])
(require '[clojure.future :refer :all])

clojure.future namespace contains all new clojure.core functions like int?, 
seqable? etc

The version numbers will follow clojure 1.9 versions. Expect this lib 
upgraded with every new Clojure alpha release until 1.9 if finally out.
