This package gets deployed as [a read-only git repo `bolt-design-system/core-php`](https://github.com/bolt-design-system/core-php), however it's source is at [`bolt-design-system/bolt` in `packages/core-php`](https://github.com/bolt-design-system/bolt/blob/master/packages/core-php), so **don't send PRs to the first repo link, send them to the second repo link!!** Categories of Twig Extension ============================ [](#categories-of-twig-extension) BoltCore -------- [](#boltcore) These are the set of custom Twig extensions globally used within the Bolt Design System + automatically wired up to other systems (ex. within Drupal via the bolt\_connect module). BoltCoreCompat -------------- [](#boltcorecompat) These are additional Twig extensions for Twig functions / filters used within the Bolt Design System's components that are specifically for cross-platform compatibility. For example, all of these extensions should already exist in Drupal enviroments by default with the exception of the `pattern_template` Twig function (which ships with the UI Patterns module). BoltExtras ---------- [](#boltextras) These are extra Twig extensions used primarily for internal testing within the Bolt Design System and are used to help build and maintain the documentation site and demos. ### Health Score 41 — FairBetter than 87% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity26 Limited adoption so far Community25 Small or concentrated contributor base Maturity82 Battle-tested with a long release history Bus Factor2 2 contributors hold 50%+ of commits How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
