Description

Gain development agility by using carefully curated, useful features, such as data storage or custom defaults. This library was created as part of the development of my other Typst projects; it contains functionality shared across multiple projects that would otherwise need to be maintained and updated individually, but is now centralized in a single place. This is not intended to be a full-fledged development toolset — although someday it might end up becoming that —, but rather a compartmentalization of shared resources and a repository of potentially useful development feature.
