Evaluating core.incubator for your project? Score Explanation
Commits Score (?)
Issues & PR Score (?)


Future home of fns proposed for core inclusion. Currently:

  • A nil-safe threading macro for interop forms (.?.)
  • An implementation of dissoc-in
  • An implementation of seqable? (deprecated - in core as of Clojure 1.9.0-alpha5)
  • A string interpolation macro (<<), originally described here.

NOTE: If you are looking for the other nil-safe threading macros -?> and -?>> they're still here, but deprecated; they were effectively promoted into clojure.core starting with Clojure 1.5 in the form of some-> and some->>, respectively.

For more details, please see the project's generated API documentation.
