Ok, thank you for your reply. I will give it a try then soon on one of
my pet projects! Thanks!

Hi Max.
I'm not actively doing any work on it. Mainly because there are no
requests for changes. It's pretty straight-forward. I haven't tested
it with later versions of Clojure, but I'm not aware of any breaking
changes, so I would expect it to work.
There are some alternatives, e.g. https://github.com/Raynes/conch

Hello,
I just found about this nice improvement over default java.shell
provided by clojure stdlib.
What is current status of this project? Is it still useful or
maybe there are alternatives?
Does it support latest clojure versions (1.6 or even maybe 1.7-beta)?
Thanks!

I'm announcing java.shell2
<https://github.com/mlimotte/java.shell2>. It is backward
compatible with clojure.java.shell. This is a Clojure library
to facilitate launching of sub-processes and piping
(streaming) data.
Features
- A declarative syntax for defining new processes to specify
input, output, encoding, and other behavior
- Handling for common use-cases (i.e. pass stdout/err of the
process to the same destination as the parent, merge stderr of
the process to stdout, output directly to a File, etc)
- The pipe macro handles all the complexity of managing
multipe streams and threads for streaming data through
multiple processes and clojure functions.
- Backward compatible with existing code that uses
clojure.java.shell (i.e. a drop-in replacement)
Shell has additional predicates like :pass, which will connect
STDOUT or STDERR of the process to the STDOUT/ERR of the
parent JVM.
(sh "wc" "-l" :in input :err :pass :out (io/file "/tmp/foo"))
So the above form reads input (which can be a file, stream,
string, etc), forwards the output to a file and redirects
STDERR to STDERR of the JVM.
And here's an example of a pipe:
(pipe
(sh "cat" :in input)
my-filter-fn ;A clojure function -- data is streamed
(sh "wc" "-l"))
This library was developed at The Climate Corporation
<http://climate.com/>, so a big thank you to them for allowing
me to open source this code under an EPL license. Climate Corp
has one of the largest Clojure development teams. We are an
established startup with offices in San Francisco and Seattle;
and are currently hiring full-time Clojure developers, data
scientists, product managers and more
<http://climate.com/careers>.
See the README for more details and many examples in the unit
tests.
I know there are other shell libraries for Clojure. My main
motivation is that I wanted something closer to the
clojure.java.shell api.
