d.Hours() will always return 0, because it is not the origin input

c:\users\stingyjack\go\bin\countdown 10s && say "final"

does the countdown, then...

'say' is not recognized as an internal or external command,
operable program or batch file.

I'm guessing I need another tool installed for that. What am I missing?

This isn't really related to countdown, but in the gif on the main page, you have a pretty rad colorful prompt. Any chance you could provide the details on how to accomplish that ;)

Thanks!

This PR closes #20

New File added:

• assets/bell.svg => notification icon (downloaded from freepik)

Edited file:

• README.md => add notification preview and credit for freepik icon
• main.go => import beeep and add function notify() detailed below

func notify(title, body, icon string) {
	err := beeep.Notify(title, body, icon)
	if err != nil {
		panic(err)
	}
}

I also call notify() on main()

func main() {
	defer notify("Countdown App", "Timer Finished", "assets/bell.svg")
	...
}

Use case: During longer meetings, we often say: "Let's have a 10 minute break and meet back at 11:45". Instead of doing them math and say: countdown 9m27s this PR allows to say countdown 11:45AM instead.

i have an idea to create notification feature in this app. My plan is to refactor this fork countdown-notifier and used beeep cross-platform notification for sending desktop notifications.

before:

$ countdown
usage:
countdown 25s
countdown 1m50s
countdown 2h45m50s$

after:

$ countdown
usage:
countdown 25s
countdown 1m50s
countdown 2h45m50s
$

d has been modified, so it does not equal original value. So d.Hours() always returns 0 because the hours part was already subtracted from d.

h := d / time.Hour
d -= h * time.Hour

It should use h instead.

There is no --help, -help, or help to show the usage. A blank command will do it.. but this is easy to implement.

Additionally this command already sends a notification on finish, it would be trivial to add a custom notification.

If you do not get to this before I do, ill probably submit a PR to fix this.

There is already exists keybinding (Esc or Ctrl-C) to stop countdown w/o running next command. It is will be helpful to add keybinding (e.g. q, s or n) to skip countdown (exit with 0 code) and run next command.

alternately, if you don't want to make it annoying by default, have it look at COUNTDOWN_ON_ZERO_COMMAND in the environment, so I can do:

export COUNTDOWN_ON_ZERO_COMMAND='echo -e "\a"'

in my .profile.

• While the countdown is running and the user decides to change the size of the terminal, the font of the countdown will recenter automatically on the next ticks.

I notice that at least d for days is not supported. I use this occasionally with the sleep command to do stuff like open a link with xdg-open in a couple days. It's also a bit more readable to see 12 days counting down than 288 hours. Not sure if sleep supports bigger units than days, but if it does, it could be good to have those as well. w for weeks should be fairly unambiguous, and if you start using capitals, M could be months.
