Re: [ClojureScript] ClojureScript Compilation via Command Line

[Mike Fikes]

In the interim, you can pass multiple -e expressions, one for each form that 
would be in the build file you'd hypothetically be evaluating.

For example:

java -cp cljs.jar:src clojure.main -e "(require 'cljs.build.api)" -e 
'(cljs.build.api/build "src" {:output-to "out/main.js"})'

It's not possible but only because nobody has contributed the necessary
patches. I'd be happy to see a comprehensive CLI story.

[ClojureScript] Issue with cljs.pprint and tagged literals/elements

[Miroslav Kubíček]

Hi there!
I am having troubles making the cljs pretty print (cljs.pprint/pprint) behave 
the same way as the regular cljs or clj print function when it goes down to 
tagged elements that are by default used to denote custom records.

See example below - pr, pr-str, print and print-str functions all use the 
default approach toward creating (edn-like) tagged element for MyRecord adn all 
produce the same result:
#cljs.user.MyRecord{:value "a"}

On the other hand pprint just ignores the record's tag and simply just 
traverses/prints it as a map:
{:value "a"}

Is there some setting and/or parameter in cljs.pprint namespace I am missing? I 
looked briefly at the code, but it seems it uses print-str by default - so 
maybe it just traverses the graph depth-first and does not check for every 
node's type?

THIS WORKS:
cljs.user=> (defrecord MyRecord [value])
cljs.user/MyRecord
cljs.user=> (pr (MyRecord. "a"))
#cljs.user.MyRecord{:value "a"}
nil
cljs.user=> (pr-str (MyRecord. "a"))
"#cljs.user.MyRecord{:value \"a\"}"
cljs.user=> (print (MyRecord. "a"))
#cljs.user.MyRecord{:value a}
nil
cljs.user=> (print-str (MyRecord. "a"))
"#cljs.user.MyRecord{:value a}"

BUT THIS DOESN'T:
cljs.user=> (cljs.pprint/pprint (MyRecord. "a"))
{:value "a"}
("{:value \"a\"}\n")
cljs.user=> (with-out-str (cljs.pprint/pprint (MyRecord. "a")))
"{:value \"a\"}\n"

Thanks for help!

Cheers
Miro

[ClojureScript] [ANN] clojurescript.org

[Alex Miller]

We are pleased to announce that http://clojurescript.org is now a site rather 
than a redirect to the github repo. Content was seeded from the CLJS wiki.

The site contribution process is the same as http://clojure.org - Contributor 
Agreement is required, but then contributions can be sent via PR. More info

* CLJS-1657: Self-host: Implicit macro loading with alias
* CLJS-1742: Add docstring for new refer-clojure REPL special
* CLJS-1274: Allow assignment to namespace-qualified names in current
namespace
* CLJS-1744: rest produces nil for larger maps
* CLJS-1740: Self-host: Need to port more of CLJS-1733
* CLJS-1741: Add :rename to :refer-clojure in ns docstring
* CLJS-1737: Self-host: clojure alias implicit macro use regression
* invalid cljs.spec/merge res call
