• Add clojure.core/intern
• Support new pod op: load-ns. This allows pod namespaces to be loaded on demand which speeds up the initial load of the pod. See docs and this bootleg PR.

Release v0.0.98 has a couple of small fixes, but most notably, it allows running bootleg as a pod. Bootleg is a CLI around generating static HTML websites. Thanks to @retrogradeorbit for his hard work on this awesome tool. Give it a try!

• babashka.pods: fix ordering of pod namespace vars: they are now handled in the order they are declared in
• #444: fix timezone issue by upgrading GraalVM (see #449)
• #446: fix location in error message in case of NullPointerException
• #447: expose flatland.ordered.map/ordered-map.
• #449: move to GraalVM 20.1.0 java11
• add clojure.core/bean and clojure.core/*print-meta*

Thanks to @retrogradeorbit, @lispyclouds and @kolharsam for contributing to this release.

• babashka/babashka.nrepl#8: fix flushing issues
• babashka/babashka.pods#6: support callback based pod functions. See docs for details.
• fix babashka.curl/delete mapping
• babashka/babashka.pods#3: implement babashka.pods/unload-pod to tear down a pod
• upgrade to GraalVM java8-19.3.2.

• Add "code" field to var section in pod protocol to support loading of client side code. This allows pods to define macros. See docs. One example of this is pod-babashka-hsqldb's with-transaction macro:

$ rlwrap ./bb
Babashka v0.0.96 REPL.
Use :repl/quit or :repl/exit to quit the REPL.
Clojure rocks, Bash reaches.
user=> (require '[babashka.pods :as pods])
nil
user=> (pods/load-pod "pod-babashka-hsqldb")
nil
user=> (require '[pod.babashka.hsqldb :as db])
nil
user=> (def db "jdbc:hsqldb:mem:testdb;sql.syntax_mys=true")
#'user/db
user=> (db/with-transaction [tx db] (db/execute! tx ["create table foo ( foo int );"]) (db/execute! tx ["insert into foo values (1,2,3)"]))
[#:next.jdbc{:update-count 3}]

Thanks @retrogradeorbit, @daviddpark and @mbjarland for contributing to this release.

• #419: add support for data readers via *data-readers*:

  bb "(set! *data-readers* {'t/tag inc}) #t/tag 1"
  2
  

  To preserve good startup time, babashka does not scan the entire classpath for data_readers.clj files.

• #424: Add classes from java.util.jar: JarFile, JarEntry and JarFile$JarFileEntry

• Add enumeration-seq

• #427: check syntax of ns macro: first argument should be present and should be symbol

• #432: split out nREPL server into its own library.
  The library adds improvements for completion of namespaces and fully qualified names.

• #435: add the clojure.zip namespace

• Fix automatic imports for java.lang.Comparable and java.lang.Process

• Include docstrings of clojure.tools.cli vars

• clojure.repl/doc enhancement: don't print hyphens when no var has been found

• Fix binding of dynamic vars that refer to functions.

• borkdude/babashka.curl#21: add curl/delete function

• classpath performance improvements

• Split out babashka.pods into its own library. This brings pods to the JVM and makes them easier to test.
• When babashka loads a pod, it sets the environment variable BABASHKA_POD to true. This way binaries can decide if they should run as a pod or not.
• clj-kondo can now run as a pod

• Add shutdown op to pod protocol. See https://github.com/borkdude/babashka/blob/master/doc/pods.md#shutdown. This fixes an issue with the hsqldb pod. Needs re-installing a new snapsnot pod binary.
• Add clojure.core/with-redefs.

Thanks to @lispyclouds for the contributed hammock time to pods!

New:

• Pods. See documentation.
• #415: Add java.util.Arrays/copyOf

Fixes:

• borkdude/sci#321: fix for variadic recur
• #413: fix associative destructuring with binding
• Fix babashka.signal namespace

• #407: add BABASHKA_FEATURE_DATASCRIPT feature flag

The following enhancements were made to add compatibility with the doric library:

• Add clojure.core/ns-resolve, clojure.core/remove-nsandclojure.core/read`
• Fix clojure.core/for: the macro did not fully qualify when and nth
• Add java.lang.Character

Thanks to @jaydeesimon for contributing to this release.

This release introduces feature flags to allow babashka to be a focused tool for the mainstream user and customizable for people who want to compile their own version of babashka.

See Including new libraries or classes and feature flag documentation.
