'''Also works with gojq, the Go implementation of jq, and with fq'''
The following relies on the ANSI terminal control codes. Unfortunately, as best I can tell,
horizontal cursor positioning via ANSI codes does not work in Terminal.app on a Mac.
Invocation: jq -nr --unbuffered -f cursor-movement.jq

# Be busy for at least the given number of seconds,
# and emit the actual number of seconds that have elapsed.
# The reason for defining sleep/1 is that it allows the idiom:
# E | F, (sleep(1) as $elapsed | CONTINUE_WITH_E_AS_INPUT)
def sleep($seconds):
now
| . as $now
| until( . - $now >= $seconds; now)
| . - $now ;
