Already using it! First off, I can save a page as PDF, there's still some issues, but at least it's more than one page.

can or can’t?

It does save and mostly looks good, but some of the layout ends up with tabular layout on top of text layout.

Some of the most fun I've had coding in the last few months has been in Clerk notebooks!

oh thats music in my ears, thanks you!

it does, been wanting to support that better in clerk for a good while…

(ns some
  (:require    [nextjournal.clerk :as clerk]))

(def ^:const ^double PI 3.14)

Clerk evaluated '/home/.../some.clj' in 39.979623ms.
Execution error (ExceptionInfo) at clojure.tools.analyzer.passes.jvm.validate/eval16782$fn (validate.clj:189).
Wrong tag: clojure.core$double@4e0d541b in def: PI

issue welcome, can take a look tomorrow

is the annotation valid?

Thanks! As far as I know annotation is valid, I'll verify it anyway.

currently suspect it’s a side-effect of analyzing more code due to build-graph change from https://github.com/nextjournal/clerk/blob/b149f2f34370125b53acd809c32764f9d6c5a01d/CHANGELOG.md#013838-2023-03-02

^double is valid and is the same as {:tag 'double}

The problem is that if I use such symbol (defined in other namespace) I also get this error.

is that a bug in tools analyzer then?

(clojure.tools.analyzer.jvm/analyze '(def ^:const ^double PI 3.14) (clojure.tools.analyzer.jvm/empty-env) {})

this is a minimal repro with only tools.analyzer

oh, indeed, hmmm

ok, it's my misuse of double tag in this case 😕

Looks to me like the https://blog.nextjournal.com/garden.html#citation-needed link isn't working?

ah right, meant to link this to the docs (which don’t exist yet)

for documentation purposes it would be great stuff (`notespace` and my metadoc supports this)

Having a combined clerk and test suite is something I’m looking for also.

We have built a clerk kaocha test thing internally, it's easy and doesn't take much code. It would be great if community members would give this a try for themselves. 🙂

I think we speak about something slightly different. Kind of embedding tests into the notebook and connect them with examples. Quick and dirty:

(defmacro examples-with-test
  [& forms]
  `(clerk/table
    {:head ["test" "code" "result"]
     :rows [~@(for [[c f t] forms
                    :let [test-code `(clojure.test/is ~(if t `(~f ~c ~t) `(= ~f ~c)))]]
                `(let [t# ~test-code]
                   [(if t# "✅" "❌" ) (clerk/code (quote ~c)) (if t# ~c (str "Expected " ~(or t f) " got " ~c))]))]}))

(examples-with-test
 [(+ 1 2) 3]
 [(+ 3 4) 5]
 [(+ 5 (rand-int 10)) >= 5])

And there you go, already a prototype 😄

I’d like a way to build individual notebooks without name clashes on index.html
