Answered: Support Clojure 1.12-alpha12 Array class notation

Sat, 25 May 2024 12:12:15 +0000

FYI unless people contribute patches first, I plan to do a round to update tools.reader/analyzer to bring them up to compatibility with 1.12, but not while things are still in alpha and may still change.

Answered: sending cljs file to repl causes reader exception

Thu, 09 Nov 2023 15:20:28 +0000

The issue should be fixed as of shadow-cljs 2.26.0, or rather tools.reader 1.3.7 which was the cause of the problem and is now the declared dependency.

Answered: How to read namespaced keywords with clojure.tools.reader/read?

Mon, 18 Nov 2019 14:26:28 +0000

If you know how to resolve the autoresolved keyword aliases, you can set the *alias-map* dynamic binding and plug something in there: http://clojure.github.io/tools.reader/#clojure.tools.reader/*alias-map*

It's described as a map, but it's invoked as a function, so I think a function would work too.

Answered: Possibility to ignore read-eval?

Wed, 09 Oct 2019 13:40:33 +0000

Doesn't sound like a good idea to me. There are some other Clojure parsers out there that might better suit your needs like https://github.com/borkdude/edamame.
