(go (loop []

> (println v)
> (recur))))
I wanted to expand it into something like a logger that writes out to a
file though, so I made the relevant test.txt file, stuck it in resources
and changed the code to look like this:
(use 'clojure.java.io)
> (use 'clojure.core.async)
>
> (def print-chan (chan))
>
> (go (loop []
> (when-let [v (<! print-chan)]
> (with-open [wrtr (writer "resources/test.txt" :append true)]
(.write wrtr v))
> (recur))))
>
> (>!! print-chan 42)
But when I do this, I find that it will only replace what is in the file,
and not append to it. Sometimes also, the output that ends up in the file
is a little odd, too. I tried to put 42 and I got * instead. When I use the
writer without the core.async functions, it works as expected. I am using
light table.
