All Ruby documentation offline with yard

Question

If I want see documentation on my gems I can do:

yard server --gems

How can I see the documentation of Ruby's standard library?

Answer 1

You have to

1. download the Ruby code archive and extract it into a directory,
2. run yardoc *.c (that will generate the core documentation), 2a. run yardoc . (that will generate the stdlib documentation but will take a lot of time),
3. run yard server.
