I would like to download the Drupal hook documentation and all that would be helpful. I saved several pages in parts on my hard drive, but it will take too much time to download all api.drupal.org. Is there a place where I can get everything at once?
The Drupal documentation is directly related to the source code. You can use the API module to use the documentation in the code to create your own local version of api.drupal.org.
The link from prasado is no longer available. This works: http://chm.kollm.org/drupal-6.chm
In addition, if you have api.module installed on a local copy of Drupal, you can browse and find the documentation built into Contrib modules such as Views, Organic Groups, etc.
If you use windows, try this link http://drupal.kollm.org/chm-drupal-6 This nice fella created a very convenient CHM file
Yes, this is great for API documentation, but for various other guides on the drupal.org man page, this is a bit more painful.
Found this here , which explains how logging on a site shows links to a printable version.
