How to rebuild rdoc for all the installed gems?

Question

I have several gems installed in multiple locations.

What is the hard/easy way to generate/re-generate:

• rdoc for all these installed gems, all at once?
• yardoc for all these installed gems, all at once?

Answer 1

yard gems

or

sudo yard gems

should do the job. You may also want to use the --rebuild flag. If you want to run a local Yardoc server for your installed gems, then run

yard server -g

Answer 2

Have you tried one of these?

gem rdoc --all
gem rdoc --all --overwrite
