A small C program that works like sleep but prints 1 dot a second, a space
after each 10 seconds, and a newline after every minute.
Go to releases to download 32-bit Windows and Linux executables (made with zig cc).
You need to pass in one or more time arguments, an integer, up to 9 digits
long, with optional suffix s, m or h (to mean seconds, minutes or
hours respectively), but unlike with GNU's sleep you cannot use fractionals.
The given arguments are summed together so passing 1h 15m and 30s will
result in a total of 4530 seconds of sleep (3600 from 1h, 900 from
15m and 30 from 30s).
You can also pass --countdown to replace the printed dots with a countdown
of seconds, or --hms to replace the printed dots with a clock-like countdown
in the format HH:MM:SS.
Also, if the terminal is a TTY (as checked by isatty function) then after
each print with above two options (but not with the default dots) the clear
ANSI sequence is sent, so while running in a TTY the program keeps changing
the single line instead of printing more lines with new values.
Option --help (and -h, -? and /?) will print the help, --sum will
only sum the times and error check but not do any countdown, --nosleep will
print all the output without any sleeping, and --print will print times to
stderr as they're being parsed. Some of these options are just to help
me in debugging and development.
Option --timer will cause the command not to sleep for any given amount of
time but to count up seconds elapsed, also using HH:MM:SS format. If that
option is used, it has to be the only option used.
