Bug - Clojure -e disables stdin

[Asim Jalis]

Is this a bug?

echo "hi" | java -cp $HOME/jars/clojure.jar clojure.main -e '(println
(line-seq (java.io.BufferedReader. *in*)))'

The output is nil.

This works fine if argument to -e is saved to a file and then the file
name is specified on the command line.

This is actually a fairly good bug report, I think.

If you look in clojure.main, the "eval-opt" fuction uses
"with-in-str", which unnecessarily interferes with using *in* within
the expression you are trying to evaluate. I was actually running into
this while trying to make a "lein repl" in clojure rather than in the
shell script.

One way to fix it would be to replace it like in this gist:

I tested out this fix and it seems to work great.

We've actually had a bug in Leiningen with a fairly tacky workaround
that was caused by this bug, so I'd love to see it fixed in Clojure.
I've created a ticket and patch:
