Which globals are always present in Clojure code? The Leiningen docs hint at there being a list of them along with their meaningful values. But I have not been able to find it.
Noisesmith on the Clojurians Slack came with the idea that you can use apropos to find the globals:
(ins)user=> (apropos #"^\*.*\*$")
(clojure.core/*agent* clojure.core/*allow-unresolved-vars* clojure.core/*assert* clojure.core/*clojure-version* clojure.core/*command-line-args* clojure.core/*compile-files* clojure.core/*compile-path* clojure.core/*compiler-options* clojure.core/*data-readers* clojure.core/*default-data-reader-fn* clojure.core/*err* clojure.core/*file* clojure.core/*flush-on-newline* clojure.core/*fn-loader* clojure.core/*in* clojure.core/*math-context* clojure.core/*ns* clojure.core/*out* clojure.core/*print-dup* clojure.core/*print-length* clojure.core/*print-level* clojure.core/*print-meta* clojure.core/*print-namespace-maps* clojure.core/*print-readably* clojure.core/*read-eval* clojure.core/*source-path* clojure.core/*suppress-read* clojure.core/*unchecked-math* clojure.core/*use-context-classloader* clojure.core/*verbose-defrecords* clojure.core/*warn-on-reflection* clojure.core.server/*session* clojure.java.browse/*open-url-script* clojure.java.javadoc/*core-java-api* clojure.java.javadoc/*feeling-lucky* clojure.java.javadoc/*feeling-lucky-url* clojure.java.javadoc/*local-javadocs* clojure.java.javadoc/*remote-javadocs* clojure.java.shell/*sh-dir* clojure.java.shell/*sh-env* clojure.pprint/*print-base* clojure.pprint/*print-miser-width* clojure.pprint/*print-pprint-dispatch* clojure.pprint/*print-pretty* clojure.pprint/*print-radix* clojure.pprint/*print-right-margin* clojure.pprint/*print-suppress-namespaces* clojure.spec/*coll-check-limit* clojure.spec/*coll-error-limit* clojure.spec/*compile-asserts* clojure.spec/*explain-out* clojure.spec/*fspec-iterations* clojure.spec/*recursion-limit*)
Compared to previous ways of finding globals this includes globals not only from clojure.core.
