Allow multiple SCs per issue

[hidde]

Currently the sc property of an issue accepts one number, for instance:

sc: 1.1.1

It would be nice if you could add an array of SCs:

sc: [1.1.1, 1.1.2]

Hey @hidde, I've gotten this working in my fork, though there are also a lot of other changes, so probably won't open a PR from that fork.

The main change was in scTable.js:

function getSCs(principleSearchString) {
  let principle = [];
  for (const issue of allIssues) {
    for (const sc of issue.data.sc) {
      if (sc.startsWith(principleSearchString)) {
        principle.push(sc);
      }
    }
  }
  return Array.from(new Set(principle));
}

const perceivable = getSCs("1.");
const operable = getSCs("2.");
const understandable = getSCs("3.");
const robust = getSCs("4.");

There was also a small change needed in the report layout around the WCAG link:

{% if issue.data.sc and issue.data.sc.length !== 0 %}
  {% for sc in issue.data.sc %}
    ...
  {% endfor %}
{% endif %}

And lastly there was the sanitizeNumber function in .eleventy.js, I just changed it to return that issues highest number SC for use in the sorting comparison when creating the collection:

const sanitizeNumbersAndReturnHighest = (numberWithDotsArray) => {
  let number = null;
  for (const numberWithDots of numberWithDotsArray) {
    const numberString = numberWithDots
      .split(".")
      .map((numb) => (numb = Number(numb) < 10 ? "0" + numb : numb))
      .join("");
    number = number < Number(numberString) ? Number(numberString) : number;
  }
  return number;
};
