Fires a terminal shell timer, which sleeps the Mac and pings you (with IFTTT or mail) before you lose your spot.
Go for a break ? Start the script: computer goes to 'display sleep' and will send you timely notifications.
Sessions on a Mac at 42 accept a stand-by time of 42 minutes before one gets automatically disconnnected.
This should not be a problem in terms of work in progress, as you duely commits all your work in progress with Git every now and then. So you are safe, you lose no code. Good. (You DO commit your work right ? Good.)
But when the seats are scarce and many students compete for Macs to get work done, it is frustrating to forget the time because you had this very interesting conversation about refactoring all your code to do all the nifty tests in bitwise, and then you find that you have been disconnected.
No work lost obviously (you commit, right ? Right ?), but, fair is fair, someone has pushed your stuff aside and is now working at what was your Mac, sitting on what was your chair.
A gentle reminder that tells you that time flies and pings you every so often to tell you how much time remains, then alerts you when it is time to come back and get back to work.
It pings you in two ways:
- by mail (set your 42 email address as VIP to get notifications on your phone's home screen)
- or via IFTTT, which should display notifications on your phone if you have installed the IFTTT app : Google Play link / Apple App Store link)
This is not preventing the disconnect, mind you. It is really the equivalent to starting a alarm or a timer on your phone. But when you use it, it put your Mac to sleep AND the timer starts.
So one command to run and you're good to go for coffee.
It won't fetch a coffee for you.
It will not make your Mac believe you are sitting at the chair and prevent log out.
It will not take your messages and organise dinner for two at a difficult to book restaurant.
It will not fall foul of Staff_SI because it is just an improved timer. No cheating.
This is just a simple shell script that runs on your Mac.
You can either run it as a .command file by clicking it, or as a .sh shell script from your ~/bin folder.
- It first sends you an initial ping or mail, so that you feel confident it is working,
- It will count down from 3 so that you may stop it in case you started it by mistake,
- Then it sets the Mac to sleep using
pmset displaysleepnow, the terminal equivalent to your belovedctrl+shift+eject. - It will afterwards, while the screen is locked, starts counting and sends a reminder after 10 mins, 20 mins, 35 mins and, finally, THREE minutes before the end of the 42 minute period.
Download it. Or, better, clone or branch it, improve it and submit a Pull Request to give back!
Drop the sleeptimer.sh file in your ~/bin folder, chmod 755 the script so that you can run it directly.
You may want to add this ~/bin folder to your shell "ENV": do so by adding "export PATH=$PATH:$HOME/bin" to your .[|z|k|c]shrc file.
Restart terminal so the new scripts gets parsed, or type reset (it reloads the .rc file). Then you may
run it by typing 'sleeptimer.sh' at anytime in your terminal
If you want to run it as a command (like, something you may double-click, as a app, with the thingie they call a mouse, for the GUI-inclined), you can use the sleeptimer.command file :
it will open terminal and actually execute the ~/bin/sleeptimer.sh shell script. This can be put, for instance, in your dock. Rename it as will. (Make sure it is also chmod 755 so that it runs on opening.)
Open sleeptimer.sh and make sure the options you want (mail and/or IFTTT) are set to true.
In the sleeptimer.sh script, set USE_MAIL=true.
This uses the mail command from terminal.
You need to ensure your mail is set up correctly on your Mac. (Remember your Day 0 of Piscine C, Chapter III exercise 0).
This uses "Webhooks" service from IFTTT.
In the sleeptimer.sh script, set USE_IFTTT=true.
You need to create an applet with the service. Using value1 and value2 as respectively title and body variable.
You need to get your unique key for the Webhook service.
You need to enter that key in the correct place in the script sleeptimer.sh (replace ENTER_YOUR_IFTTT_WEBHOOK_KEY by your key).
Doing the whole IFTTT set-up stuff is left as an exercise for the reader (I'll come back and elaborate on this once I remember how exactly one shall do it).
NB: You don't need to do all this if you set USE_IFTTT=false.
This is a really crude and horrendous script, I wrote it during my Piscine c because I was too stupid to watch time during my breaks, breaks I was spending drining too much coffee, trying to understand the basics of c and discussing with many various and interesting fellows piscineux.
Not enough sleep, no idea of what I was doing, but at least I had my computer do some work for me.
Use at your own risk, and don't complain if you came back too late on tuesday at 11am during another piscine and the E1 was so full that somebody jumped at your PC as soon as the login screen appeared.
- Clean up the code so that the variables can be changed depending on one's IFTTT applet specifics.
- Update readme.md to add instructions to create applet proper.
- Find how to link /rebind a key shortcut natively (not using any plugin) so that one may juste use
ctrl+shift+ejectto start the script.
