#173: Following up on the breaking change in v0.0.44, <input> is now renamed to *input*, which is now also a dynamic var, which looks and feels more idiomatic.

https://github.com/borkdude/sci/issues/188: add letfn
#173: BREAKING: rename *in* to <input> (in the user namespace). The name was a poor choice for two reasons. It shadowed clojure.core/*in*. Also, the value was not a dynamic var, but the earmuffs suggested otherwise.
#174: add clojure.edn/read
fix clojure.string/re-quote-replacement

#149: Add support for java.time API. This is an example how you can print the current time in California:

#!/usr/bin/env bb
(def now (java.time.ZonedDateTime/now))
(def LA-timezone (java.time.ZoneId/of "America/Los_Angeles"))
(def LA-time (.withZoneSameInstant now LA-timezone))
(def pattern (java.time.format.DateTimeFormatter/ofPattern "HH:mm"))
(println (.format LA-time pattern))

#160: Add support for java.lang.ProcessBuilder. See docs. This replaces the conch namespace (BREAKING).
#162: Add support for java.util.Base64:

$ bb '(String. (.decode (java.util.Base64/getDecoder) "YmFiYXNoa2E="))'
"babashka"

Add support for java.lang.Math:

$ bb '(Math/pow 2 3)'
8.0

#147 Add cheshire. The cheshire.core namespace is available via the json alias in the user namespace:

$ bb '(println (json/encode {:a 1}))'
{"a":1}

$ bb "(require '[cheshire.core :as cheshire]) (cheshire/generate-string {:a 1})"
"{\"a\":1}"

#137: implement console REPL. Babashka will now start a repl when no arguments are provided, or with the argument --repl. Using rlwrap is recommended.

$ rlwrap bb
Babashka v0.0.39 REPL.
Use :repl/quit or :repl/exit to quit the REPL.
Clojure rocks, Bash reaches.

Support for (dynamic) vars. See sci documentation: https://borkdude.github.io/sci/#vars. This also fixes #135.

$ bb '(def ^:dynamic *x* 1) (binding [*x* 10] (prn *x*)) (prn *x*)'

New

Add support for in-ns and ns:

$ cat script.clj
(ns foo (:require [clojure.string :as str]))
::str/foo

$ bb script.clj
:clojure.string/foo

Note that require still does not load external files. This will probably be added in a future release.

Upgrade to GraalVM 19.3.0. This means that SSL now works without any additional configuration due to static linking of the necessary library:

$ bb '(-> (slurp "https://www.clojure.org") (subs 0 55))'
"<!DOCTYPE html>\n<!-- This site was created in Webflow. "

New

#112: Add binding, with-out-str and with-in-str:

$ ./bb '(let [w (java.io.StringWriter.)] (binding [*out* w] (println "hello")) (str w))'
"hello\n"

$ ./bb "(count (with-out-str (println \"hello\")))"
6

$ ./bb '(with-in-str "hi" (read-line))'
"hi"

Notes:

Currently binding only works with clojure.core/*in* and clojure.core/*out*
*in* has a special meaning in babashka expressions, but you can refer to Clojure's *in*by fully qualifying it: clojure.core/*in*.
