Execute all of your project's .repl files with transcriptor.

Add the desired olical/lein-transcriptor version to your :plugins vector and com.cognitect/transcriptor to your :dependencies.

You may need to upgrade your Clojure version to one that has clojure.spec support.

# This will execute all of your .repl files in this directory or below.
lein transcriptor

# You can provide a path to run all .repl files under that specific path.
# When you don't provide a path, it defaults to "."
lein transcriptor ./my/repl-files
