A stand-alone ClojureScript REPL for macOS and Linux based on JavaScriptCore.
Home page: planck-repl.org
On macOS:
$ brew install planck
On Ubuntu:
sudo add-apt-repository ppa:mfikes/planck
sudo apt-get update
sudo apt-get install planck
For other Linux distros, see Building below.
Launch Planck by entering planck at the terminal.
Get help on command-line options by issuing planck -h.
For more details, see the Planck User Guide.
It is possible to write Clojure-idiomatic scripts like the following:
(require '[planck.core :refer [line-seq with-open]]
'[planck.io :as io]
'[planck.shell :as shell])
(with-open [rdr (io/reader "input.txt")]
(doseq [line (line-seq rdr)]
(println (count line))))
(shell/sh "say" "done")Many of the familiar functions and macros unique to Clojure have been ported:
eval, file-seq, line-seq, intern, ns-resolve, read, read-line, read-string, resolve, slurp, spit, with-open
as-file, as-url, delete-file, file, input-stream, make-input-stream, make-output-stream, make-reader, make-writer, output-stream, reader, resource, writer
See Building Wiki for setting up OS-specific build tooling and dependencies.
Pre-made build environments for various environments are available in build-envs.
$ script/build
The resulting binary will be planck-c/build/planck.
Specify -fast to quickly build a development version that skips Closure optimization:
$ script/build -fast
If you specify -Sdeps or -R<alias>, it will be passed through to the underlying clojure command during the build process. This can be used to specify a ClojureScript dep to use.
$ script/test
