env_print: Pretty-print an environment

In hadley/rlang: Functions for Base Types and Core R and 'Tidyverse' Features

Pretty-print an environment

Description

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.

Usage

env_print(env = caller_env())

Arguments

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