Alex - I could not find a link to the Clojure.org github project on the clojure.org site. Should one be added under "Contributing" somewhere? Alan On Thursday, January 14, 2016 at 7:45:06 AM UTC-8, Alex Miller wrote: > > The new http://clojure.org is alive! > > Most of the content on the site is

GMail code formatter

Just discovered a cool Chrome extension so that you can get proper syntax highlighting when pasting code into your email. It turns plain-old code into something nice to read: *Plain:* (defn truthy? "Returns true if arg is logical true (neither nil nor false); otherwise returns false." [arg]

clojure.spec regression bug for 1.9.0-alpha6

Hi - Just noticed that the :ret function in fdef seems to be ignored in 1.9.0-alpha6: user=> (require '[clojure.spec :as s]) user=> (defn dummy [x] (if x "yes" "no")) user=> (s/fdef dummy #_=> :args (s/cat :x integer?) #_=> :ret integer?) user=> (s/instrument #'dummy) user=> (dummy 3)

Re: GMail code formatter

​​Hmmm, Never thought of that: (defn truthy? "Returns true if arg is logical true (neither nil nor false); otherwise returns false." [arg] (if arg true false) ) ​Doesn't look half-bad, although ​I don't always have Cursive/IDEA open. Alan On Tue, Jun 14, 2016 at 9:38 PM, Colin Taylor

Re: Too over complicated

Olek - You may find some of the convience functions you are missing in the Tupelo library. In particular: https://github.com/cloojure/tupelo#convenience-in-testing-seqs https://github.com/cloojure/tupelo#keeping-it-simple-with-not-nil Keeping It Simple with not-nil? Clojure has the build-in

Crossclj.info shows outdated dependencies

Hey - Many of you are probably already aware of the centralized API documentation available at https://crossclj.info . However, I just noticed a new (to me) feature: CrossClj shows the outdated dependencies of a project! Checkit out at:

Awesome VIM cheatsheet!

Hey - I just found this awesome VIM cheatsheet, laid out in the form of a keyboard showing all of the keys and what they do (normal, shift, control, etc), along with an extensive legend. Check it out at: http://michael.peopleofhonoronly.com/vim/ It is from a wiki of cheatsheets located at:

Sisyphus on Fire

Hi. I just read very well-written post by Marc Phillips on the Cognitect blog. He describes some of the current antipatterns that have hijacked the original idea of "Agile" development. Please read! Alan http://blog.cognitect.com/blog/2015/12/2/sisyphus-on-fire -- You received this message

(type ...) vs (class ...)

Hey - Just saw something on the clojure.core/type function: (defn type "Returns the :type metadata of x, or its Class if none" {:added "1.0" :static true} [x] (or (get (meta x) :type) (class x))) I have never seen this before, and it appears the :type metadata is not used in the clojure.core

Re: How is the emphasis of “data over code” different than the XML advocacy of the early 2000s?

I do think the whole "code is data" thing is a bit overstated. The earliest computers used paper tape for data records: At Bletchley Park, the "data" (ciphertext to be broken) was encoded onto the paper tape in the photo. The "code" was hardwired into the design of the machine & its

Re: [ANN] Specter 0.9.2

Looks great, Nathan. I also highly enjoyed your recent interview on the Cognitect podcast . One quick question: In the first example below from the README (verified at the repl), it seems that the (srange ...) function sometimes behaves as a half-open
