I’ve been using yad-calendar as a simple agenda for a while, but recently I upgraded it, and now it pops open a yad window to enter a new description for the selected day, or edit exiting descriptions.
To use it, double click any day of the current month.
It’s a very basic agenda, without alarms and limited (not really, but in practice, yes) to a single line of text…

#!/bin/bash
################################

Adicionar_evento(){
# Dia sem evento, adicionar um...
event=$(yad --width=800 --form --center --title="Calendar: $day ..." --field="") && event=${event%|*}
space=" "
text=$day$space$event
echo $text >> $HOME/yad-calendar.txt
exit
}

Editar_evento(){
# Dia com evento já existente
entrada=$(grep -h $day $HOME/yad-calendar.txt)
line=($(grep -n $day $HOME/yad-calendar.txt | head -n 1 | cut -d: -f1))
altered_entry=$(yad --width=800 --center --title="Editar evento existente" --undecorated --form --field="" "$entrada")
#retirar ultima letra, desnecessária
entry=${altered_entry%|*}
#gravar texto na linha original:
awk -v line=$line -v texto="$entry" 'NR=='line' {$0='texto'} { print }' $HOME/yad-calendar.txt > $HOME/yad-calendar.txt.TEMP
cp $HOME/yad-calendar.txt.TEMP $HOME/yad-calendar.txt
exit
}

import -f Adicionar_evento Editar_evento
touch ~/yad-calendar.txt && [ -s ~/yad-calendar.txt ] || echo "28/06/2020 This is how yad-calendar entries work! Add ONLY ONE line per day, starting with the date. If nothing shows up in the calendar, try another date format like dd-mm-yyyy" > $HOME/yad-calendar.txt

#ecrã principal
day=$(yad --calendar --undecorated --mouse  --details=$HOME/yad-calendar.txt --button="X":1)
if [[ $foo -eq 1 ]]; then
    exit 1
  fi
#se não se seleccionou nenhum dia, sair simplesmente
[ -z "$day" ] && exit

#se dia seleccionado ver se tem conteudo prévio ou nao
if grep -q $day $HOME/yad-calendar.txt; then
   Editar_evento
   else
   Adicionar_evento
fi

The comments are in portuguese, but there is no text that needs to be localized in the script itself!

Edit: How to use this “yad-agenda”:
Call the script and double click any day of the currently displayed month (A day with a description will be shown in “bold”):
– If it has no discription, a small window will pop up, allowing you to add a description to that day.
– If the selected day already has a description, a pop up window (without any window decorations) will show the complete line that referes to that day, including the full date. If you press “cancel” you cancel that event and remove it’s entry. If you change the date in the begining of the line, you will move the event to that new date.
You can see the entire “agenda” and directly edit it using any text editor- it’s in your home file, under the name yad-calendar.txt (yeah, Skidoo, I like poluting my home folder 🙂 ).
You can add, to that file a line with comments, begining with “#”. For example:

 #Anniversaries
 25/12/2020 baby Jesus
 #Holidays
 01/01/2021 New year day; Hang over :-)

etc

Hello PPC,
Just tested your script while translating it. Nice idea and good work, I think.

Please check line 26 in this version
import -f Adicionar_evento Editar_evento
as well as in the most recent version I’ve got from marcelocripe. This line produces an error message only, since there is no import command in bash shellscript available. So it will get executed by ImageMagick instead, and produce an errormessage only.
import-im6.q16: unrecognized option '-f' @ error/import.c/ImportImageCommand/820.
I’m quite sure you simply can drop this line unless I am very much mistaken.
Greetings and best regards for the New Year
Robin.

During the week-end and last night I updated yad-calendar even more, and localized all output to English:
Changes:
-New GUI to enter events in an “empty” new day.
–If you only enter the event’s description it will be considered an all day event.
–If you enter a start date it will show up with the prefix @ – example: “@ 12:00 Launch time”
–If you enter an end time, it will be displayed like this: “@ 12:00-13:00 Launch time”
-New GUI that shows day’s events, when user double click a day with one or more events ( “all day events” are displayed on the top of the page)
-New “experimental” GUI to search for events in the agenda (it’s case insensitive)
– I fixed the bug Robin noticed.

To do’s:
– Confirm valid times and date
– I’m working in a GUI to add events to a day that already has events (instead of editing the day’s full line manually)- it’s almost done
– To finish off, I’m looking for a way to edit/remove entries from a day. Finding a way to move events to a new day would be ideal, but very troublessom…
– Find a nice script ( don’t want to right it from scratch) that runs on very little RAM and CPU ) to act as alarm, for the entries on the agenda- this would basically make yad-agenda a fully featured (yet basic and low on resources) Personal Agenda… – hey, even Linux Mint does not have an agenda on their calendar, so if the Dev’s pick this up, it would be a nice handy feature for those of us that don’t like to use google calendar on their phones…

It’s all work in progress, but, I believe, quite usable as is…

I almost forgot, I wrote a companion script, to be added to the system’s startup file, that displays events for the current day, if there’s any (please note that’s not any kind of alarm).
There was a user, now probably on a very heavy Calendar program that asked exactly for this… It’s easier done than creating alarms… 🙂

#!/bin/bash
#Display todays events using data in $HOME/yad-calendar.txt, if there's any
day=$(date +"%d"/"%m"/"%Y")
entrada=$(grep -h $day $HOME/yad-calendar.txt)

if test -z "$entrada" 
then
      echo "Nothing for today"
else
      echo "Events found for today: $entrada"

#Create table for todays events
reminder_time=$(echo $entrada|cut -d' ' -f2)
reminder_date=$(echo $entrada|cut -d' ' -f1)
line=($(grep -n $day $HOME/yad-calendar.txt | head -n 1 | cut -d: -f1))
#grep $day $HOME/yad-calendar.txt |cut -d' ' -f1 --complement
eventos_existentes=$(grep $day $HOME/yad-calendar.txt |cut -d' ' -f1 --complement)
echo $eventos_existentes
x=$(tr -dc '@' <<<"$eventos_existentes" | awk '{ print length; }')
echo The number of events for the day is $x
let "x=x+2"
numero_de_eventos_no_dia=$(tr -dc '@' <<<"$eventos_existentes" | awk '{ print length; }')
echo "" > /tmp/listar_eventos_do_dia
i=1
until [ $i -ge $x ]
do
grep $day $HOME/yad-calendar.txt |cut -d@ -f$i >> /tmp/listar_eventos_do_dia
  ((i=i+1))
done
#list todays events in a yad window:
evento_a_editar=$(yad --title="Calendar - $day" --button="OK":1  --width=550 --height=550 --center --separator=" " --list  --column=""  < /tmp/listar_eventos_do_dia)

Thanks for all input.
I have 2 good news: my yad-calendar interface is nearly completed, it looks and acts almost like a full blown calendar application! (The single thing still remaining is a GUI to delete existing entries AND check for validity of date and time).
Better yet- I developed, from scratch, a script, than runs on about 750 Kb of RAM, to monitor timed events that are in ~/yad-calender.txt file. Events there do not have to be entered via any GUI but do have to obey this simple rules:
– one day per line
– start with [date] (four digits for the year), a space, “@”, [time of event], space, [event description].
– there can be multiple timed events per day (but the date comes only on the start of the line):
Ex: “15/01/2021 @07:30 Wake up @09:00 arrive at work @12:30 leave for lunch @18:45 Go home”

Note: you can have an all day event just after the date, before, the first “@”, it will be ignored…
EX: “25/12/2021 Christmas @22:30 Open presents”

Save the script, make it executable (I call it yad-calendar-alarm.sh) and place it in your startup file (ex: (without commas) “~/yad-calendar-alarm.sh &”)
It runs on 750Kb of RAM all the time, it doubles that value every 30 seconds to check for new events. RAM use is negligible, even on my single core CPU…

The “alarm” script, it’s still a BETA, please test carefully, it’s not for mainstream use yet:

#!/bin/bash
### alarme sound from de https://unix.stackexchange.com/questions/1974/how-do-i-make-my-pc-speaker-beep
pkill $BASH_SOURCE
killall sleep
today=$(date '+%d/%m/%Y')
#read alarm and event from file
eventos_existentes=$(grep $today $HOME/yad-calendar.txt |cut -d' ' -f1 --complement)
echo $eventos_existentes
x=$(tr -dc '@' <<<"$eventos_existentes" | awk '{ print length; }')
echo The number of events for the day is $x
let "x=x+2"
#Count events (one per each @)
numero_de_eventos_no_dia=$(tr -dc '@' <<<"$eventos_existentes" | awk '{ print length; }')
echo "" > /tmp/listar_eventos_do_dia
i=2
until [ $i -ge $x ]
do
#grep $day $HOME/yad-calendar.txt |cut -d@ -f$i >> /tmp/listar_eventos_do_dia
grep $today $HOME/yad-calendar.txt |cut -d@ -f$i |cut -d" " -f1
target_time=$(grep $today $HOME/yad-calendar.txt |cut -d@ -f$i |cut -d" " -f1)
event_description=$(grep $today $HOME/yad-calendar.txt |cut -d@ -f$i |cut -d" " -f2)
initial_time=$(date +"%H":"%M":"%S")
diference=$(echo "$target_time
$initial_time" | 
  (read later_time; read former_time;
    former_seconds=$(date --date="$former_time" +%s);
    later_seconds=$(date --date="$later_time" +%s);
    echo $((later_seconds-former_seconds)) ))
nohup sleep $diference &&  yad --center --width=300 --no-buttons --window-icon="/usr/share/icons/papirus-antix/22x22/apps/calendar.png" --title="antiX Calendar" --text="\n $target_time - $event_description \n" --text-align=center & speaker-test --frequency 200 --test sine & sleep 2 && pkill speaker-test

@PPC: Thank you very much for your efforts in creating these tools.

By sharing them, people can either:
– use them as is, and benefit from a light, simple, easy to use tool
– use the idea, but modify it slightly to suit their own personal tastes and preferences
– learn from the straightforward code that you have written, and use it to create their own tools for the same or other purposes

Whether people do this, something else, or just use “standard tools” I feel that this kind of sharing and discussion is healthy and promotes more learning and sharing. Once again, thank you very much for all of your thoughtful, useful contributions!

Very nearly completed (and fully functional) version of yad-calendar (I rebranded it “antiX Calendar”)

Changelog:
-I now use a variable, in the start of the script, to select the calendar text file. If you want to change the file, or file path, just edit it
– GUI’s to add/cancel events (timed and all day events) to empty days, days with events.
– Use icons and window name in all yad windows
– Interface and comments should be fully localized to English
– I changed the event input window’s to a more logical and faster to use layout
– Cleaned up the code a bit
– The script now looks more polished
– Used with the previous companion scripts, this is almost a fully fledged calendar, with alarms, etc.

TODO’s:
– Validate date and time fields
– Clean up the code even more
– Integrate the companion scripts with the main antiX calendar script (they can be used with cli options, example: “antix-calendar –alarm” to activate alarms, “antix-calendar –today” to display the day’s events at start up.
– Think of a way to add recurring events (at least annually, it’s handy for birthdays and holidays)
– Add a way to edit results of the “search window”
– If a better “coder” than me want to help with bugs/missing features (and ideally add import/export function to the calendar’s file), all help is welcome

Not a bug, but features:
If you edit the “date” field of a day with events and remove it, that will erase the entire day’s contents
I kept the original “manually edit day” button because it can be handy to manually edit many events in a day, instead of clicking through the GUI- but that can be subjected to change- the user can always edit the calendar text file in a text editor… I kept it there also to quickly fix and bugs left on the edited day.

BUGS:
-No validation of date and time: just like in a pen and paper agenda, you can enter “31/02/9999 @25:79 Just noticed I’m dislexic”… Because of that, you can add an event to a day with previous events, without a date. It will come up as “16/01/2021 @I messed up”- the correct way to add an all day event is clicking the date, on the top of the day’s window and edit the day’s field.
-If you add a new event to a day with events, that entry is sorted and inserted on the correct place, but, if you edit a timed event and change it’s time, it will not get sorted out, and will remain out of place, if you change it to a time previous or post other event’s time… I’m too tired to solve that one for now, it’s not serious, but I dislike bugs…

@Robin: sorry, as you can see I was in the process of heavily reworking my code, and did not reply, I’ll try to PM you tomorrow…

Very nicely done. Thank you for posting your work. I am certainly going to use your script instead of the calendar I’ve been using. Thank you. Looking forward to your future updates:)

For some reason, all the examples I found on-line about validating time in a bash script never quite worked out, and I ended up devoleping one myself.
The script now checks validity of start time of events (both the ones added to empty days and days with more events), but the time of the event’s “end” is not validated.
since I wrote the validation script from scrach, it’s “smart”: you can enter “9:15” and it gets corrected to “09:15”.

Unfortunatly I’m losing my momentum… Because the script already works quite well, I won’t change it much, maybe try to merge the 2 auxiliary scripts with each other and with the main “antiX Calendar” one.

Changelog:
– Validation of event’s start time
– Fixed regression that stopped to have more than one timed event per day (it was a bug in the clean up part of the script)

TODO’s/BUGS:
– Still, if you change an event’s time, it is not automaticaly sorted out… It’s a minor problem, but an anoying one

The current version:

Please test the script and report any bugs/suggestion. Feel free to contribute, it was a very tiresome process, converting the simple yad-calendar to an agenda.

Right now, the script if fully usable, in a final Beta level – feel free to use it, but do not rely on it for important appointments (I always use a pen and paper agenda, to be on the safe side, for all important stuff).

Sigh… I found some regressions and was able to fix them, and also, dispite not wanting to do that, I had to partly repeat the code to always make sure the day’s contents are in order.
Also, along the way, a new regression- validating the time field does not work when adding events to days with other events…
For now, I have to take a rest… Time validation will have to wait…

I have a sick mind and am dreaming of having an “Popup Alarm” checkbox and an “Alarm sound” field where you select a sound file to play if you want a sound file to play when it pops up. It could submit a cron job to do it, so it would take almost no resources.

But you would need to remove it from the crontab if it was cancelled and add it when new or moved. I wonder if a sound can be played from cron?

Yes, it’s quite a script already. I did test it here.

@BobC – My tiny alarm script (that reads time of the alarm from the yad-calendar.txt file can be made to work with terminal input/yad window to select a one time only alarm (that was how I tested it).
The alarm script, being based in “sleep” runs in almost no RAM and CPU at all- less than it takes to run Cron.
That said, I do run cron on my work PC and thought about using it as an alarm, but it seems to take some time to update the cronjobs- you can set an alarm for 5 minutes in the future and it may not go off because cron didn’t update- at least that was what I read online… But, yes, you can create a cron job, for example, to run mpv playing a mp3 file, everyday at 08:00, and use it as an alarm clock- I read on script that did something like that…
Also- did you ever heard about the “rtcwake” command? https://linux.die.net/man/8/rtcwake
You can use it to suspend your pc and then wake it up at a certain time- and yes, use a script, in conjunction with that, to play an audio file/video at a certain time (Example, use rtcwake to wake your pc at 7:58, and, then have a cronjob or a sleep command have mpv play some sound…
I resorted to the “sleep” command because it never fails, does not require cron to be installed and it’s very light…

The “antiX Calendar” main script tired the soul out of me, I was trying to fix all the possible quirks before I lose steam… The time validation part of the script is particularly nasty to make work… But has is, the script works perfectly – as long as you take care to write valid times (same thing as writing something in your paper agenda)
It now automatically organizes daily entries entries (that was bugging me).
Any user that uses the event’s “end time”, please be careful- I did not make the alarm script work with a time value that includes “end time” too (it’s an easy fix, but I’m dead tired, completely depleted…
Even so, I hope anti picks this up- I always imagined how cool it would be if we could use the yad-agenda, just one click away as a real PIM… Now I already do that- a yad window just came up, warning me it’s time to go to bed…

I guess I’ll take tomorrow off…
P.
