Category filter not working with Quarto 1.6/1.7?

[mcanouil]

Description

If you find yourself with a Quarto site where the category filter is no longer working in your listing, it might be because of an outdated version of the libraries in the freezer (i.e., _freeze).

Check for _freeze/site_libs.
Delete it and render again.

The key file is site_libs/quarto-listing/quarto-listing.js which should contain the following at the beginning (it's not the only difference, but that's the obvious one since it's at the beginning):

Outdated	Current (>1.6.42)
window.quartoListingCategory = (category) => { if (categoriesLoaded) { activateCategory(category); setCategoryHash(category); } };	window.quartoListingCategory = (category) => { // category is URI encoded in EJS template for UTF-8 support category = decodeURIComponent(atob(category)); if (categoriesLoaded) { activateCategory(category); setCategoryHash(category); } };

Edit: if you are using a custom listing, ensure you are using: <%= metadataAttrs(item) %> documented as a requirement in Custom listing page for "sorting, filtering, and pagination".
You also need to update the EJS variable to retrieve the category, now encoded as base64:

<div class="listing-category" onclick="window.quartoListingCategory('<%= utils.b64encode(category) %>'); return false;">

instead of the outdated (<=1.6.40):

<div class="listing-category" onclick="window.quartoListingCategory('<%- category %>'); return false;">
