Ruby and Ruby on Rails offline API documentation

In the past I used railsbrain.com to have a nice and handy offline API documentation.

But they stop at version 2.3.2

Is there any other solution with latest version.

Browser-based Solution – Updated Oct 19, 2017

DevDocs (https://devdocs.io/) uses your browser's IndexedDB to store the documentation you want. Make sure you follow the instructions on how to install the docs before you go offline.

Manual Download:

I used this commands on my server so I could get the files faster (they were cached, go figure).

wget -r -k -p http://api.rubyonrails.org/

• r - recursive
• k - convert links to point to local files
• p - get all images, etc needed to display the html pages

Then I compress the folder so I can download it without overhead.

rar a -r rails_api.rar api.rubyonrails.org/

• a - add files
• r - recursive

YARD Server

I prefer the yard format over rdoc.

1. Install the gem gem install yard,
2. Regenerate all the documentation gem rdoc --all --overwrite, and
3. Run the server for the gems yard server --gems.
