(Script) Display a calendar for Journal entries

Hi,

I just played around a bit the last days and implemented a feature on my (very short) Silverbullet wishlist, and I thought, it might be handy for others, too.
As I’m not familiar with writing plugins, yet, I’m sharing my codeblocks at first. You will have to alter it a bit to fit your own preferences/directories/Language.

Hint: My Journal contains files with this naming-format: /Journal/2024-11-22_Fr

The output looks like this (all markdown based):

Every day is a link to a page. If page exists already, it is marked in bold.
Current day is marked with “(xx)”.
You can add marks for other important days, too (marked with “!”). This is defined with a list of days as secon

First the space-script itself. Can be placed on any page, it defines the needed functions:

silverbullet.registerFunction({name: "generateCalendarMarkdown"}, async (year, month, markdays, today,nohead) => {

    const monthNames = [
        'Januar', 'Februar', 'März', 'April', 'Mai', 'Juni', 
        'Juli', 'August', 'September', 'Oktober', 'November', 'Dezember'
    ];
    const daysOfWeek = ['Mo', 'Di', 'Mi', 'Do', 'Fr', 'Sa', 'So'];
    const date = new Date(year, month - 1, 1);
    let markdown = ""
      if (! nohead ) {markdown = `## Journal Kalender: ${monthNames[month - 1]} - ${month} / ${year}\n\n`;}
    markdown += '| ' + daysOfWeek.join(' | ') + ' |\n';
    markdown += '| ' + '--- |'.repeat(7) + '\n';

    // Adjust the start day for Monday
    let startDay = (date.getDay() + 6) % 7;

    // Fill initial empty cells
    for (let i = 0; i < startDay; i++) {
        markdown += '|    ';
    }

    while (date.getMonth() === month - 1) {
        let day = date.getDate();

        let daystr = String(day).padStart(2, ' ');

        let datePage = "Journal/" + String(year) + "-" + String(month).padStart(2, '0') + "-" + String(day).padStart(2, '0') + "_" + daysOfWeek[date.getDay()-1] 
      
        if (await space.fileExists(datePage + ".md")) {  //datePage
          daystr = "**[[" + datePage + "|" + String(day) + "]]**";
        } else {
          daystr = "[[" + datePage + "|" + String(day) + "]]";
        }

        if ( (today === undefined && day === Temporal.Now.plainDateISO().day ) || (today === day) ){
            markdown += '|' + " (" + daystr + '' + ") " ;
        }
        else if (markdays.includes(day) ) {
            markdown += '|' + " ! " + daystr + '' + " !" ;
        } else {
            markdown += '| ' + daystr + ' ';
        }
        if ((date.getDay() + 6) % 7 === 6) {
            markdown += '|\n';
        }
        date.setDate(date.getDate() + 1);
    }

    // Fill trailing empty cells
    if ((date.getDay() + 6) % 7 !== 0) {
        for (let i = (date.getDay() + 6) % 7; i < 7; i++) {
            markdown += '|    ';
        }
        markdown += '|\n';
    }

    return markdown;
});

You display the calendar on a page with this query, with these options:

  1. year
  2. month
  3. list of dates to mark extra (e.g. [23,11,26]), e.g. Birthdays, etc. in current month
  4. define another date to mark for today, if undefined take actual today. Useful, e.g. if you want to mark the date of a older Journal page
  5. if set to true, do not render a heading
{{generateCalendarMarkdown(2024,11,[23,11,26],undefined,false)}}

On my todo list

  • creating this as plugin
  • better formatting (size, color) with CSS / space-style
  • adding more special markings
  • make it language independent (as it is currently in german, only)
    (more ideas, hints and help welcome)

Have fun :slight_smile:
