cal and repetitive patterns

[darksun]

Hi,

I am looking for a way to create a calendar with repetitive patters.

For example:
4 days on
2 days off

A friend of mine works a shift job and asked me to have a simple way to eg color the days red when he works and leave it uncolored when he has the days off. He works 4 days on and then 2 days off, every time.

I love simple, spartan and lightweight things so I was thinking to have a bash script to color the output of the command "cal" in that way: chosen a starting day, 4 days of a color (eg red) and 2 days leave it uncolored.
I have searched online and asked tgpt but cannot come up with a way to do so.

Thank you

@MochiMoppel is the person to ask for advice....he's a master of shell scripting......if anyone can color highlight 4 days on and 2 days off with the cal command as the base.......he'd be the guy I'd bet on.

Meanwhile since this already sounds like a very useful thing, I'll be looking for a solution as well.......

thank you @rockedge .

The top would be to create a calendar event (calendar software eg mobile phone's calendar app ) but I cannot come up with an idea to do so with the available options under recurrent events. Maybe it does not exist a way to do so.

As second option is the one I mentioned in my first post, then a "print screen" of the terminal output and export it as image

EDIT: silly me, as I was thinking about the idea of the calendar event on my android calendar app it was easy to implement, creating a event lasting 4 days and repeating it every 6 days

@darksun
Be prepared for crazy s**t!
I have written a bash script using urxvt and cal command to display three different kinds of event, based on code by @MochiMoppel
ATM i don't have the time to explain, but to give an impression of what can be done please see screenshot and code below:

it looks cool and promising, but I can see references in ?Dutch? and as well as files (txt, images) present on your storage media.

[HerrBert]

As i said, it's just to give an impression of what can be done...
Comments and references are in German. Image is only for the window icon of urxvt.

I have written a bash script using urxvt and cal command to display three different kinds of event, based on code by @MochiMoppel

By me? There used to be a related thread in the Murga forum (https://oldforum.puppylinux.com/viewtopic.php?t=108481) but it seems to be broken. Maybe @rockedge knows what is going on there. I can access the first and the third page, but not the second.

Whatever the trigger for your script was, I use a similar script which pops up a gtkdialog calendar when clicking the JWM clock. It's based on the same idea of formatting the cal output and shows the current day in green and any event in red. One of my goals was to make the calendar as small as possible.

I use this calendar mainly for birthdays or other anniversaries and for one-time events with a specific date in the future. However for doing what the OP asks for it's probably not suitable.

@MochiMoppel Thank you for the information about the non-functioning page.

This happens since the many database conversions done to save the murga forum's data. Seems that there are occasional problems with the custom html tags that need to be defined in javascript that cause errors during page parsing and generation, causing the blank page we are seeing.

I am working on it.

[rockedge]

@MochiMoppel, @fredx181,

I fixed the problem with the blank page on the original topic on the old forum. It's caused by a missing closing custom tag </r> in the source html for post #28. I modified it in the database directly by adding the closing tag. It does appear that post #28 had it's text corrupted during the conversion process.

Fixed post -> https://oldforum.puppylinux.com/viewtop ... 7#p1013517

Actually good to know how to fix this, since there are other blank pages lurking, probably for the same reason, that I can now more than likely fix.

Yes, that's the one I was looking for. I also found that I posted an early and simplified version of my current calendar here. Completely forgot all this stuff.

Perhaps this provides a solution: https://www.vertex42.com/calendars/shif ... endar.html

This should exactly do what the OP aims for. It claims that it requires Excel 10 (which I don't have), but it loads into Gnumeric and I see no reason for it not to work in Gnumeric - after a bit of tweaking. It uses only conditional formatting but no macros, which would be a no-go.

This seems handy.

From ChatGPT:

Code: Select all

#!/bin/bash

# Define start date for the schedule (yyyy-mm-dd format)
start_date="2024-11-10"

# Number of days to generate the schedule for
days_to_generate=30

# Loop through the days and create the schedule
current_date="$start_date"
for ((i=0; i<$days_to_generate; i++)); do
    # Get the current weekday (0=Sunday, 1=Monday, ..., 6=Saturday)
    day_of_week=$(date -d "$current_date" '+%u')
    
    # Determine if it's a work day or an off day
    if ((i % 6 < 4)); then
        schedule="Work"
    else
        schedule="Off"
    fi

    # Print the current date and schedule
    echo "$current_date - $schedule"

    # Increment the date by one day
    current_date=$(date -I -d "$current_date + 1 day")
done

Result:
