Problem with dynamic variables

[ralcantaraperez]

Hi. I'm having problems with dynamic variables and a script loaded by closh-zero.jar. If I do it in the REPL it runs fine. This is the script file content:

#! /usr/bin/env closh-zero.jar

(def ^:dynamic my-var "initial value")

(binding [my-var "new value"]
  (println my-var))

This is the error:

Thanks for the report. It looks like the problem is with the custom reader. For example following also does not work (prints nil):

#! /usr/bin/env closh-zero.jar

(println (meta ^:dynamic {}))

I will try to look into it.

This is now fixed in master.

I would like to fix some more bugs and release a new version after that. In the meantime you use manual build. Clone the repo, run npm run pkg-java and you will get the binary in target/closh-zero.jar.
