This namespace mainly provides reflection capabilities to assist you in exploring code in a REPL. It comes with macros that are automatically imported into your REPL environment, but you can use them outside of one as well.
These macros allow you to explore code by listing/searching available vars in a namespace and viewing a var's documentation or source.
(Error->map o)
Constructs a data representation for a Error with keys: :cause - root cause message :phase - error phase :via - cause chain, with cause keys: :type - exception class symbol :message - exception message :data - ex-data :at - top stack element :trace - root cause stack elements
(apropos str-or-pattern)
Given a regular expression or stringable thing, return a seq of all public definitions in all currently-loaded namespaces that match the str-or-pattern.
(doc name)
Prints documentation for a var or special form given its name, or for a spec if given a keyword
(ex-str {:keys [:clojure.error/phase :clojure.error/source :clojure.error/line :clojure.error/column :clojure.error/symbol :clojure.error/class :clojure.error/cause :clojure.error/spec], :as triage-data})
Returns a string from exception data, as produced by ex-triage. The first line summarizes the exception phase and location. The subsequent lines describe the cause.
(ex-triage datafied-throwable)
Returns an analysis of the phase, error, cause, and location of an error that occurred based on Throwable data, as returned by Throwable->map. All attributes other than phase are optional: :clojure.error/phase - keyword phase indicator, one of: :read-source :compile-syntax-check :compilation :macro-syntax-check :macroexpansion :execution :read-eval-result :print-eval-result :clojure.error/source - file name (no path) :clojure.error/line - integer line number :clojure.error/column - integer column number :clojure.error/symbol - symbol being expanded/compiled/invoked :clojure.error/class - cause exception class symbol :clojure.error/cause - cause exception message :clojure.error/spec - explain-data for spec error
(find-doc re-string-or-pattern)
Prints documentation for any var whose documentation or name contains a match for re-string-or-pattern
(source n)
Prints the source code for the given symbol, if it can find it. This requires that the symbol resolve to a Var defined in a namespace for which the .cljs is in the classpath. Example: (source filter)
