Hi, folks
This is small piece of code that is inspired by haxl,
muse(https://github.com/kachayev/muse),
urania(https://github.com/funcool/urania). Not a library.

(Thread/sleep 1000)

I have a case where I'm reading a Clojure data structure serialized to

Clearly I want to avoid clojure.core/read-string. The

Presuming you're in Clojure, just use clojure.edn. clojure.edn is written
in Java and targets the edn subset of Clojure's syntax. Presuming you're
reading typical edn data, this is the best answer.
clojure.tools.reader is a version of the Clojure reader (not the edn
subset) written in Clojure (
Specs in docs are nice, great addition.
2 things related to them :
- what is `quotable` ? Couldn't find its docs in the page
- I suppose `:closure.core.spec.alpha/exclude` refers to a spec, but again it's
absent from the docs. A quick search in clojure.core and spec.alpha repos
didn't reveal it.
Thanks Alex. This makes sense.
It did occur to the the recommendation in the cheatsheet might be
aimed at ClojureScript compatibility. Since I'm in JVM Clojure only
for this project I'll switch over to clojure.edn.

To a large degree Clojure and ClojureScript should be the same from a reader
compatibility point of view.

Hi,
I am trying to use clj-http in my clojure program. I am trying to do the
whole thing in a "light-weight" manner - without creating a project and all
or using lein. Is that possible? or do I need to use Lein?
Regards,
Kashyap

All of the core specs are defined in an external library (so we can update
it more frequently than Clojure
Sure. You need a jar for Clojure and a jar for clj-http and then just run
Java with those in a classpath:
java -cp clojure.jar:clj-http.jar my-program
There is a lighter weight tool that we've added in Clojure 1.9 (also works
with 1.8) that can help in assembling classpaths and serving as a run
I am pretty sure that clojure.tools.reader.edn is a version of the Clojure
reader specifically for the edn subset, hence the name of the namespace.
That said, no need to add a separate dependency on clojure.tools.reader if
you would prefer to avoid it, and you are reading EDN inside Clojure on the
Thanks Alex ... just what I was looking for - putting the jars in classpath
that is!
I'll try out the new tool a little later though.

Hey, gang! There is something important here. Gold!, amidst the nuts and
bolts. A humdinger of first-rate philosophical insight is tucked,
inconspicuously, way toward the end of the linked demo video. In a word,
it is a bat-it-out-of-the-park answer to the docstring-improvement
chatter. Ta
Right on! I don't remember which of my insights did the humdinging but I'm
glad you liked it.

In addition to tools.deps, which reads dependencies etc from a deps.edn file,
you might want to look at Boot http://boot-clj.com which allows you to use
libraries via the command line without needing a project or source files etc:
boot -d clj-http repl
This will start a Clojure REPL (anywhe
Very nice! Kudos.
