Search for Memfault YouTrack Issues in text and create Search Link

index.html

<textarea id="input" placeholder="Paste text with issue ids with the pattern MFLT-1234" rows="10"
    style="display: block; width:100%"></textarea>
<a id="link" href="">Click me</a>

<script>
    const textArea = document.getElementById("input");
    const linkElement = document.getElementById("link");

    function updateLink() {
        const issueMatches = [...textArea.value.matchAll((/\bMFLT-\d+/g))];
        const issueStrings = issueMatches.map(m => '' + m);
        const issues = [...new Set(issueStrings)];

        linkElement.innerText = `Open YouTrack Search for ${issues.length} issue(s)`;
        const issueList = issues.join(',');
        const searchTerms = ["issue id:", "aggregate Is duplicated by:", "aggregate Duplicates:"].map((s) => s + issueList)
        linkElement.href = `https://memfault.myjetbrains.com/youtrack/issues/MFLT?q=${encodeURI(searchTerms.join(' or '))}`;


        return true;
    }

    // yes, wasteful – but the easiest way to keep Link in sync
    setInterval(updateLink, 500);

    textArea.focus();
    updateLink();
