I've been using variations of HTML traspilers for a couple of years now. First versions were in PHP with native DOMDocument parser; more recently implemented in Node.js. The core engine is really small. There's a registry of custom tags, and it walks the parsed tree of tags, runs callbacks, building the final HTML string. The rest of the functionality depends on registered tags. A tag can render HTML, CSS classes, styles (combined in head), generate JS (combined at end of document), fetch stuff from database.. In your submission history, I found the following gem. If this is possible, then I think your idea of a framework-agnostic style system based on HTML tags is not too crazy. ;) <database name="bookstore" defaultIdMethod="native"> <table name="book" description="Book Table"> <column name="id" type="integer" primaryKey="true" autoIncrement="true" /> <column name="title" type="varchar" required="true" primaryString="true" /> <column name="isbn" required="true" type="varchar" size="24" phpName="ISBN" /> <column name="author_id" type="integer" /> <foreign-key foreignTable="author" onDelete="setnull" onUpdate="cascade"> <reference local="author_id" foreign="id" /> </foreign-key> </table> <table name="author"> <column name="id" type="integer" primaryKey="true" autoIncrement="true" /> <column name="first_name" type="varchar" /> <column name="last_name" type="varchar" /> </table> </database> (From: https://cameronspear.com/blog/a-different-and-better-approach-to-database-migrations-in-php/ https://cameronspear.com/blog/a-different-and-better-approac...)
