wgHTML

wgHTML imports and incorporates static HTML pages into Drupal. One writes HTML pages using an HTML editor (e.g. kompozer) and upload them into a subdirectory in your website. The HTML page is stored on disk, rather than being stored as entries in the database. The pages are rendered as if they're part of the pages managed by Drupal.

This means one can write pages using whatever means desired such as a WYSIWYG web editor, or autogenerating pages from a backend process.

Installation is difficult as it requires modifying the .htaccess file.

The wgHTML home page has a long and useful discussion thread concerning the development of this module.

The README has misleading documentation on the configuration of .htaccess. What I just added is the following:

  RewriteCond %{REQUEST_URI} \.html?$|\.txt$|\.doc$|\.me$ [NC]
  RewriteRule ^(.*)$ index.php?q=/wghtml/show [L]

This goes in the standard .htaccess file just before the <IfModule>. Note the RewriteCond does not include .php as a pattern, so that it does not interfere with PHP execution. One should also drop .doc and .me from this list.

In summary this offers a useful way to edit some pages using a WYSIWYG editor or other means. However it clearly presents an installation challenge.
