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.
