This prints:

  • The label and the parent label.

  • Whether the environment is locked.

  • The bindings in the environment (up to 20 bindings). They are printed succintly using pillar::type_sum() (if available, otherwise uses an internal version of that generic). In addition fancy bindings (actives and promises) are indicated as such.

  • Locked bindings get a [L] tag

Note that printing a package namespace (see ns_env()) with env_print() will typically tag function bindings as <lazy> until they are evaluated the first time. This is because package functions are lazily-loaded from disk to improve performance when loading a package.


env_print(env = caller_env())



An environment, or object that can be converted to an environment by get_env().
