#elvdoc:var after-command
#
# A list of functions to call after each interactive command completes. There is one pre-defined
# function used to populate the [`$edit:command-duration`](./edit.html#edit:command-duration)
# variable. Each function is called with a single [map](https://elv.sh/ref/language.html#map)
# argument containing the following keys:
#
# * `src`: Information about the source that was executed, same as what
#   [`src`](builtin.html#src) would output inside the code.
#
# * `duration`: A [floating-point number](https://elv.sh/ref/language.html#number) representing the
# command execution duration in seconds.
#
# * `error`: An [exception](../ref/language.html#exception) object if the command terminated with
# an exception, else [`$nil`](../ref/language.html#nil).
#
# @cf $edit:command-duration

#elvdoc:var command-duration
#
# Duration, in seconds, of the most recent interactive command. This can be useful in your prompt
# to provide feedback on how long a command took to run. The initial value of this variable is the
# time to evaluate your [`rc.elv`](command.html#rc-file) before printing the first prompt.
