How to generate rdoc for a gem in an rvm gemset?

Question

I am using rvm and the rb-gsl gem. I have created a gemset with rvm 2.7.3@my_app . I have a global option to not generate rdoc documentation. If I run

gem server --dir=gempath/ruby-2.7.3@my_app

I can view my the rb-gsl gems at http://0.0.0.0:8808 . But I cannot click on the rdoc link because there is is no documentation generated for that gem. How do I do generate the documentation for the gem so it is in 2.7.3@my_app?

Answer 1

You can generate docs directly with the gem command:

gem rdoc rb-gsl --no-ri

The --no-ri switch skips the generation of ri documentation (the command line tool to fetch gem docs). It saves a little bit of disk space if you are not using ri . Otherwise you can remove it and it will generate both RI and RDoc documentation at the same time.
