Excellent. Will investigate. Currently using espeak to call out pomodoros (among other things - weather, motivational quotes, reminders) at set times. But of course you tune out after a while. This might be a more flexible solution.

EDIT: CLI is the future :)

OK, based on the comment thread I'm now trying this:

    sleep 25m; espeak "Take a break!"; notify-send "Get a cup of coffee, stretch, ignore existential angst"

I recently started using Timetrap ( https://github.com/samg/timetrap) and find fantastic. Covers a lot of corner cases while still being incredibly simple to use.

But does it beep at you? That actually looks awesome though--thanks for sharing that.

> Around 100 LOC

Say what? To ring the bell after sleeping based on a parameter?

To be fair it does slightly more than that (relative times, absolute times, etc) but it is somewhat ironic considering that it advertises itself as an alternative to one liners like "sleep 4231; beep".

You can do sleep 15m; beep

One of the reasons to use this is to avoid beep, which may not even be enabled on your machine.

Use echo '\a' that's what this program uses anyway... It's literally sleep $1; echo '\a' or you can use at if you want exact time.

X11 bell almost never works for me.

GNU sleep is around 150 loc, and does significantly less...

GNU programs are not a reference. They must have usage(), and handle --help and --version. Even /bin/true.

  coreutils-8.25$ wc -l src/true.c
  80 src/true.c

Ding has `--version`, and a help message too :P

To be honest, a big chunk of it is just handling user input and attempting to provide useful error messages.

This made me smile. I usually pop open the chrome timer or use my phone. I also just started trying out Strict Timer (chrome extension). As simple as these are, I think you've managed to reduce the motion necessary from the user to its absolute lowest level for a parameterized timer. Thanks for the tool.

Sweet! I saved the link. My intention is to take a look at the source code and then write my own ding-ding cli tool. It will be fun and I think it will give me a nice feeling when using it.

Thanks for the inspiration!

Consider using \b instead of printing a new line every time. I've a huge scrollback configured and it can silently crash my terminal given a large enough wake time!
