babashka
Clojure library for shelling out / spawning sub-processes
E.g.: ``` (process ["foo" "bar"] {:color :green :prepend "FOO"}) ``` This would be useful in babashka tasks where multiple processes are running in parallel so you can distinguish them.
The use case for tee is to redirect output to stdout but also to capture it in a file. We could make a built-in construct for this so you can...
``` clojure (require '[babashka.process :as p] '[clojure.java.io :as io]) (with-open [w (io/writer "hello.txt")] (-> (p/pipeline (p/pb '[echo foo]) (p/pb '[cat "bb.edn"])) last (p/process '[cat] {:out w}) p/check)) (slurp "hello.txt") ```...

The reason for this is that adding a shutdown hook by default creates a potential memory leak problem: the closure will be retained until shutdown. In case of lots of...
This is a deadlock: ``` (-> (process ["cat"] {#_#_:out (io/file "/tmp/foo.csv") :in (io/file "/Users/borkdude/Downloads/1mb-test_csv.csv")}) check) ``` since the stream can't write anywhere, it's waiting before it can exit. This works:...
`check` fails with the following error when passed the `*err*` stream: ``` Execution error (IllegalArgumentException) at babashka.process/check (process.cljc:106). Cannot open as an InputStream. ``` To reproduce on the REPL: ```...

Hi, it is considered a useful aid in shell scripting to echo the commands being executed. This is a request to include such an `:echo true` option in `shell` or/and...
