Hi,
For a clojar I'm writing <http://github.com/cldwalker/table>, I'd like to
know a user's terminal width so I can resize output appropriately. All the
following techniques, which work fine in a ruby repl, don't work in
leiningen2:
$ lein repl
user=> (System/getenv "COLUMNS")
nil
user=> (clojure.java.shell/sh "tput" "cols")
{:exit 0, :out "80\n", :err ""}
; This is incorrect as my terminal width is 238
user=> (clojure.java.shell/sh "stty" "size")
{:exit 1, :out "", :err "stty: stdin isn't a terminal\n"}
The only thing that does work is if I `export COLUMNS`, something I don't
have to do for a ruby repl. Thoughts on why none of these approaches work
and what a correct one would be?
Thanks,
Gabriel
