Re: Who Uses import-vars?

In the Tupelo library, I have been using `import-fn` and `import-macro` from Potemkin so that I can define functions/macros in a single namespace `tupelo.impl`, but then expose an API in "user-visible" namespaces like: - tupelo.core - tupelo.char - tupelo.test - etc Perhaps I've been

OK, I upgraded lein to 2.8.1, and it removed one of the error messages. I still have one remaining: WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by clojure.lang.Reflector

Re: [ANN] Clojure 1.9.0-beta4

Hi. 1.9.0-beta4 works great for the Tupelo library on java 1.8, but I get the following warnings using Java 9.0.1: ​WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by dynapath.defaults$eval380$fn__381 to method

Nice screencast overview of Specter

I just saw this on YouTube and thought you may enjoy it: https://youtu.be/rh5J4vacG98 While there is lots of written documentation on Specter, the live-coding and narration of what one is seeing provides some nice examples. Enjoy, Alan -- You received this message because you are subscribed to

Re: Help ship Clojure 1.9!

Before Clojure 1.9 is shipped, I would like to reiterate the appeal from many in the community to stop the terrible, permanent mistake that is *clojure.core/any?* For those who have not seen past emails on this topic, you may view the main threads here: -

Re: any? in clojure 1.9.0 alpha

id a permanent pollution of the language with a gigantic mistake such as *any?*. At the very least, the function could be moved to *clojure.spec/any?* from *clojure.core*. If we insist on adding this blatant contradiction to *clojure.core*, we won't even have the excuse of a committee to blam

Re: [core.spec] Stricter map validations?

While it doesn't use spec, you can do this using the validate-map-keys helper function in the Tupelo library . It verify that a map does not contain any keys other than those you specify. The unit test shows it in action: (ns tst.demo.core (:use demo.core

Re: Clojure rookie vs parsing

While Instaparse is (IMHO) the best parser for use with Clojure, you don't have to start from such a low level (i.e. parsing a char stream text file). Just re-write your original problem a little and you can skip writing a custom parser. In Clojure, perhaps the most popular format (certainly the

The Empire Strikes Back: Microsoft Visual Studio IDE Integration for F#

Here is an interesting talk from MS Build 2017 conference, especially when compared to similar capabilities in Clojure/Cursive, etc. For the first time they can do code completion, IDE REPL integration, and simple refactorings (e.g. "Rename Variable"). They also have an interactive data explorer

SymbolHound search engine

Re: Functional Pattern to Replace Temp Var

You are already doing exactly the right thing by having a temporary variable. To be precise a code fragment like: (let [expensive-answer (some-fn x y z) final-result { :k1 (f1 expensive-answer) :k2 (f2 expensive-answer) :k3 (f3 expensive-answer) }
